China Chengdu Xiangdao Technology Co., Ltd. Company News

In the past two years, the charging pile industry, which has been advancing rapidly, has entered a period of industry reshuffle. At present, most of the charging pile enterprises that have been out of the market are small and medium-sized enterprises with insufficient capital strength or too aggressive expansion, but the life of the leading enterprises is not easy. The neck, the low utilization rate of charging piles, and too many constraints on the operation of charging stations, etc., the common problem is that it is too difficult to make a profit. Faced with a brutal knockout before making a profit, this is the embarrassment faced by many companies attracted by the so-called "trillion" market in the charging pile industry.   At present, some of the companies that are out of the game and those that are facing out of the game are speculative companies that have no technology and no funds. Looking at the charging pile industry, they want to find a fish in troubled waters. question. After the fierce market competition, one or two giant companies will eventually be formed. After mergers and reorganizations, the industry will eventually enter the era of oligopolistic competition. In such a vicious competition environment, there is such a company, which took less than 3 years to become a well-known enterprise in the new energy industry and ushered in its "highway".   Chengdu Xiangdao Technology Co., Ltd. focuses on providing professional solutions for intelligent IoT cloud platform, electric vehicle charging business and electric vehicle charging station operation services.   Although Xiangdao Technology is a rising star, it has transformed and upgraded from the previous manufacturing industry to the current new energy industry, but its previous manufacturing foundation has made it a full-industry chain charging pile production, manufacturing, sales and operation enterprise. After 3 years of development, the company has become stronger and stronger, with many R&D personnel and strong product innovation capabilities.   In 2021, the situation of the new energy industry will change, and there will be many losers. It can be said that it is a cold winter for the industry, but Xiangdao Technology has maintained stable revenue growth and bloomed enthusiastically in the cold winter. To explore behind the success of Xiangdao Technology after its transformation and upgrading from a manufacturing industry to a new energy industry, it is not difficult to find that in the initial period of savage growth, Ruispeed Intelligence has always maintained high innovation, and at the same time, the customer's requirements are the company's standard. Criteria, quality is the foundation, and after-sales is the guarantee. With the continuous development and use of charging piles, customers have higher and higher requirements for quality, and the long-term high-quality performance has gained a batch of customers and industry reputation for Ruisu Intelligent. It is the charging pile supplier and strategic partner of many well-known operating companies such as Didi Xiaoju Charge, Wancheng Wancharge, and Midea Infore Environment. Continue to increase investment in research and development, aiming to improve its own innovation ability and win the market with high-quality products.   The output voltage range of this independent air duct DC charging pile is DC200V~1000V, and the maximum output current can reach 250A, which can provide constant full power output for buses, logistics vehicles and cars. The biggest highlight of this charging pile product is its unique charging pile system design. The charging pile no longer needs to be waterproofed separately for the charging module, nor does it need to install AC contactors, dustproof cotton, exhaust fans and other components. It can be completely dustproof, waterproof, anti-salt spray and anti-condensation, and the module is maintenance-free.   Xiangdao Technology focuses on the overall solution of electric vehicle charging system. In order to better solve the industry pain point problem of frequent charging failures due to environmental factors, after many researches and investigations, we finally designed and developed this integrated dual-gun independent air duct DC charging pile . According to the requirements of GB/T 18487.1, the protection level of charging piles installed outdoors shall not be lower than IP54. However, the charging modules used in the charging piles on the market generally adopt the "direct ventilation" heat dissipation mode, and the protection level is generally IP20. However, the electronic components are seriously heated, and high-speed fans are required for forced air cooling, and the components are in contact with the external air for a long time. , Due to dust blockage, salt spray corrosion, rain and condensation, etc., the charging module fails frequently. We believe that the protection level of the charging module should be higher than the IP54 protection level of the charging pile. Therefore, the electronic components are completely sealed and designed with independent air ducts for heat dissipation. In this way, the charging module can completely avoid dust, Problems such as salt spray and condensation have reached a maintenance-free state and greatly improved operational efficiency. If the heat dissipation, dustproof, waterproof and other aspects of the charging module can be designed, and the core components of the charging pile can be protected, it will not only help reduce the incentives for the frequent failure rate of the charging pile, but also reduce the maintenance cost of the charging operator. It is beneficial to prolong the service life of the charging pile and improve the operation efficiency. The service life of charging pile modules on the market is generally 1-3 years, and some charging piles in harsh environments can only last for 3 months.   If the charging station adopts an integrated dual-gun independent air duct DC charging pile, the service life of the core module is expected to increase to more than 5 years. Compared with products designed in traditional air-cooled mode, the use of this product can make the system design of charging piles more concise and can greatly reduce production costs and maintenance costs. In the future, DC charging piles are designed with independent air duct charging piles for environmental protection. And heat dissipation is bound to become a new mainstream trend. It's not spring, a hundred flowers bloom and spring is full of gardens.   As a leader in the charging pile industry, Xiangdao Technology not only hopes that it can have excellent product quality and high innovation, but also hopes that other domestic brother manufacturers can join forces and contribute to China's new energy. .  

The benefits of electric vehicles are here! In Panyu District, Guangzhou, another open charging station was built.   A comprehensive service area for new energy vehicles that integrates people, vehicles and life will be built here, and it will be used as a pilot to promote this business model in local alumni associations by brainstorming and working together.   Pictures taken on the spot     Engineer is debugging  

In the 21st century, the oil resource crisis and the harm of global warming are becoming more and more serious. In order to cope with energy and environmental challenges, the world's major countries and automakers have developed clean and environmentally friendly new energy vehicles, especially electric vehicles. It has become a widespread consensus and concern. Strategic focus, the world auto industry has entered a period of comprehensive upgrading. As of June 2019, the total global sales of new energy vehicles was 6.3774 million. Similar to China, India, which also relies on oil imports and suffers from severe smog, has, without exception, opted for the development route of new energy vehicles for the transformation and upgrading of its auto industry. India became the first country to propose a timetable for the exit of gasoline vehicles, with an ambitious plan to make all new passenger cars in India electric vehicles by 2030. India hopes to use this to become one of the world's central markets for the manufacture of electric vehicles. The Indian government also announced incentives for electric vehicles, cutting electric vehicle production taxes and creating incentives for companies that manufacture lithium batteries and charging infrastructure. The government has indicated that it will invest 10 billion rupees (about 1 billion yuan) to subsidize the construction of charging piles, and plans to build 1,000 charging stations across the country, especially in Delhi, Chandigarh, Delhi, Mumbai and Mumbai, Surat, Pulau A charging station will be built every 25 kilometers on major highways in the region to accelerate the realization of India's electric vehicle development plan.   The reason why Xiangdao Technology's products are appreciated by Indian friends is that thanks to its in-depth efforts in technology research and development and product innovation, it has formed an industry-leading overall solution for electric vehicle charging systems. Since this year, Xiangdao Technology has launched a flagship product - a new one-piece dual-gun independent air duct DC charging pile. The output voltage range of this independent air duct DC charging pile is DC200V~1000V, and the maximum output current can reach 250A. It can be used for constant full power charging for various models such as buses, logistics vehicles, and cars. In order to better solve the problem Due to the frequent industry pain points such as charging failures caused by environmental factors, after many researches and investigations, this integrated dual-gun independent air duct DC charging pile was finally designed and developed. The performance indicators of charging piles are in a maintenance-free state, which not only effectively reduces the incentives for the frequent failure rate of charging piles, reduces the maintenance cost of charging operators, but also helps to prolong the service life of charging piles and improve operational efficiency. In the future, the design of DC charging piles with independent air duct charging piles for environmental protection and heat dissipation will definitely become a new mainstream trend.   For many years, Xiangdao Technology has focused on providing professional solutions for intelligent IoT cloud platform, electric vehicle charging business and electric vehicle charging station operation services. To explore behind the success of Xiangdao Technology's transformation and upgrading from traditional manufacturing to an excellent enterprise in the new energy industry, it is not difficult to find that Xiangdao Technology has always maintained a high level of innovation. In order to ensure continuous increase in R&D investment, we aim to improve our own innovation ability and win the market with high-quality products. Under the environment of people's increasing environmental awareness and strong support and encouragement from governments around the world, people's recognition of electric vehicles has gradually increased, and electric vehicles have increasingly become a world trend. For the Chinese charging facility enterprises that have stood out in the construction of the world's largest charging network, they should play a more active role and play a more important role in the construction of the global charging network. The Chinese charging station manufacturing enterprises represented by Xiangdao Technology, At this time, go abroad and go to the world!

If electric vehicles can also replenish a large amount of energy in a few minutes like fuel vehicles, so that the vehicle can continue to travel hundreds of kilometers, the so-called range anxiety will disappear. Therefore, the charging method of electric vehicles has undergone a transition from slow charging, fast charging to overcharging. Higher cruising range and faster charging methods will be the future development direction of electric vehicles.   Therefore, news about the development of electric vehicle fast charging technology is often reported in the newspapers. In 2020, San Francisco-based startup Ample launched a charging network that it claims can fully charge an electric car in 10 minutes. This year, Dr. Rachid Yazami, famous for inventing the graphite anode in lithium-ion batteries, said that we charged a high-density battery in 10 minutes, seven times faster than Tesla's 70 minutes .   Everyone mentioned the concept of fully charging in ten minutes. In fact, in order to meet the needs of car owners and a sense of fast experience, this is also the pursuit of many car companies. Last year, Toyota announced that it will launch a 500-kilometer battery life model in 2021, which can be charged from empty to full in 10 minutes; Huawei also pointed out in the communication meeting that energy digitalization is the future trend, as the energy industry gradually Going digital and charging in 10 minutes will greatly improve efficiency.   . The liquid-cooled supercharger series adopts advanced thermal management concepts and cutting-edge electronic circuit technology to achieve liquid-cooling cooling treatment for the charging gun, which can enable the vehicle to be fully charged within 10 minutes with a current of up to 600A, which not only solves the problem of high-power charging charging guns The problem of heat dissipation, and the problem of noise disturbance of charging piles is improved, which greatly improves the application prospects of new energy vehicles. Charging for ten minutes may become the standard in the electric vehicle industry.” After all, the longer and longer battery life can effectively improve the single cruising range of electric vehicles, but the battery life is ultimately limited, and charging is required to replenish energy anyway. Only The faster the charging speed, the better the user's charging experience can be.   Chengdu Xiangdao has been deeply involved in the charging industry for many years, dabbling in the national standard and European standard AC and DC chargers, with an independent research and development platform, using the whole industry chain charging pile to produce modules, the products are safe and reliable, and the technology is mature and stable. The 480KW split type supercharged liquid-cooled pile and the 180KW one-piece supercharged liquid-cooled pile have been developed successively, and other models of the series will be launched in the future. From liquid cooling source, liquid cooling gun to liquid cooling charging module, etc., we have overcome difficulties all the way, forged ahead, and achieved a series of achievements. In the future, we will work hard to reduce costs and improve efficiency, and strive to popularize and popularize super-filled liquid-cooled piles. In addition, Chengdu Xiangdao has also developed a charging treasure for the automobile industry, which allows the charger to be attached to the wings and fly freely, which solves the problem of car owners’ lack of electricity and throws sights halfway, and realizes the takeaway of the charging industry. These include 7KW, 10KW, 21KW, 42KW, 84KW and other national and European standard AC charging piles, 60KW, 90KW, 120KW, 180KW, 240KW integrated DC charging piles, 240KW, 360KW, 480KW split-type piles.   Chengdu Elephant Road is an intelligent manufacturing enterprise with a whole industry chain. Self-developed advanced controllers and intelligent IoT cloud platforms provide a full set of station construction solutions and efficient operation and maintenance services for charging facility operators. It has achieved a full range of services from charging station production and after-sales service, related technical support and training, as well as providing preliminary new site survey, planning, mapping, construction guidance, and solution solutions.

In 2020, the China Electricity Council announced a new standard for high-power fast charging, the supercharging standard, jointly developed by China and Japan. With the continuous expansion of the new energy vehicle market, consumers have higher and higher requirements for charging convenience. In order to meet the charging needs in more different scenarios and improve the use efficiency of charging piles, ultra-large fast charging technology has once again become the focus of attention in the industry. DC high-power charging has become an inevitable trend in the future development of the new energy vehicle industry.   According to the latest data, the number of new energy vehicles and charging facilities that meet the 2015 version of the national standard is about 4.5 million and 1.52 million, respectively. At the current stage, the charging power range of public charging facilities is mainly concentrated between 60kW and 180kW, and the charging time is 0.5 to 2 hours. With the continuous increase of vehicle mileage, some users have an urgent need for higher power and faster charging, and hope that the charging time can be shortened to 20 minutes or even shorter. Wang Binggang, head of the national new energy vehicle innovation engineering expert group, further pointed out that there are three main application scenarios for fast charging. The first is for private electric vehicles that need to be charged at public charging stations for various reasons, such as when traveling long distances or temporarily finding that there is not enough power and no Cars with charging conditions in parking spaces; secondly, operating vehicles with a long daily mileage, including rental, tourism, logistics, and online car-hailing; the third is buses. On the whole, for the consideration of long-distance travel and operating vehicles, a certain number of super fast charging piles should be deployed in public charging piles to meet the corresponding needs.     In fact, car companies have seen market demand in advance and actively began to deploy accordingly. Liu Kai, director of the Technology and Certification Department of the China Charging Alliance, said that many car companies are currently developing fast-charging models, including Geely Krypton, GAC Aian, BYD, Great Wall Motor, and Tesla. At this year's Shanghai Auto Show, all Kia EV6 models support 400V and 800V charging, and the latest 800V high-voltage platform of Hyundai IonIQ 5 supports ultra-high-power charging up to 350kW. Dongfeng's Lantu Automobile recently announced that it is developing a super fast charging based on the ultra-high voltage platform. technology. At the same time, parts suppliers have also released product plans to support fast charging. In addition to the Ningde era that has previously announced fast charging technology, Honeycomb Energy has released new fast charging technology and corresponding batteries for the first time at this year's Shanghai Auto Show. The second-generation 4C fast charging core has a capacity of 165Ah and an energy density of more than 260Wh/kg. It only takes 10 minutes to achieve a SOC (state of charge) of 20% to 80%; Schaeffler's new motor series products can also achieve a voltage level of 48 ～800V, power level 15～300kW and above are fully covered. Not long ago, Ouyang Minggao, an academician of the Chinese Academy of Sciences, pointed out at a seminar organized by the Electric Vehicle Hundred People's Association that to solve the worries of charging, fast charging technology with higher power is needed. Super fast charging is the general trend, and the industry needs to promote the adoption of ≥800V electric vehicles. Higher voltage platform. Ouyang Minggao emphasized that for private passenger cars, based on the development prospects of vehicle-network integration and high-power fast charging technology and the trend of integrated battery-chassis design, I am more optimistic about charging. According to the research of Ouyang Minggao's team, it is completely feasible to charge a car with a cruising range of 600 kilometers for 200 kilometers in 5 minutes. Compared with the slow charging, the convenient and efficient fast charging charging pile is obviously more in line with the appetite of consumers, and it has also become the focus of competition between car companies and charging pile companies. Ji Xuehong, professor of North China University of Technology and director of the Automotive Industry Innovation Center, believes that the research and development and popularization of high-power charging technology has become one of the important factors to promote the progress and development of the industry. For example, the power of the fast charging pile of the State Grid has reached 160kW; BAIC, which is active in new energy vehicles, has recently launched a high-power charging pile with a power of 150kW; and among foreign companies, Tesla uses the second-generation supercharger. The fast charging power has reached 350kW, and the charging power of Porsche can reach 450kW. Some car companies are already actively leading the construction of fast-charging charging piles according to the promotion plan of high-power fast-charging models. For example, the charging gun developed by GAC Juwan Technology Research Institute based on the 2015 version of the national standard and adding a liquid cooling system supports a maximum current of 600A, the maximum voltage of the charging module supports 1000VDC, and the power output of the charging pile is not less than 480kW, and can be upgraded to 600kW. At a charging rate of 6C, the charging time from 30% to 80% is only 5 minutes. Gu Huinan, general manager of GAC Aian, also said that if you want to charge 1,000 kilometers in 8 minutes, you need to build high-power fast charging piles. It is technically possible, but the cost is high. We will promote it at a rhythm.   Therefore, the traditional air-cooling technology has long been unable to meet the heat dissipation requirements for charging piles with hundreds of kilowatts of power, and liquid-cooling technology has become the most reliable solution at present. Chengdu Xiangdao successfully developed a 500kW liquid-cooled super fast charging pile in 2021. This means that a new energy vehicle charged with this product can be charged from 0 to 80% within 10 minutes at the fastest. In fact, the principle of liquid cooling technology is not difficult to understand. A special circulation channel is set between the cable and the charging gun, and the cooling liquid for heat dissipation is added to the channel, and the liquid circulation can be pushed by the power pump to take out the heat. Liquid-cooled cables are currently the most widely used. Compared with ordinary cables, they can conduct electricity while dissipating heat with coolant. But the difference between liquid cooling and air cooling is that its sealing must be done well, because once the pipeline leaks, it is easy to cause the cooling system to fail. In addition, liquid cooling can also reduce the diameter of the cable, and ultimately make the charging equipment lighter. Therefore, in terms of technical paths, the technical paths of charging station manufacturers are basically the same, and the charging piles that are as cool and fast as possible are produced.   Chengdu Xiangdao researches high-power liquid-cooled charging technology. With the continuous advancement of the R&D team, the product has undergone several structural upgrades and improved reliability and performance. In October 2020, Ruisu's high-power liquid-cooled charging system (including charging piles, charging guns, high-voltage wiring harnesses, connectors, charging bases, busbars, and debugging kits) entered the real vehicle testing stage, and has already cooperated with many passenger car companies. Jointly do real vehicle verification. Xiangdao high-power liquid-cooled charging pile is a DC charging device for the future charging system. It can also match the 2015 national standard charging gun. Under the condition of cooling, the charging current is as high as 600A and the voltage is 1000V. On the premise that the vehicle battery can withstand In theory, it can achieve the goal of charging to 80% in 10 minutes at the fastest. It can effectively solve the problem of charging time for long-range mileage vehicles, rental, logistics, network-hailing operation vehicles, mega-city buses, and expressway vehicles. At present, this product has been supplied in batches. In order to meet customer needs for a long time and focus on the development trend of new energy electric vehicle technology, Ruisu takes high-voltage and high-current charging as the core research and development power to provide new energy vehicles with complete high-voltage, high-power fast The overall solution of the charging system.   In the future, Xiangdao will make every effort to promote the technological development of high-power liquid-cooled charging piles. In order to relieve users' anxiety about charging, it will continue to improve in terms of charging power, safety, and applicability. On the one hand, it provides technical exploration and practical experience for the formulation of my country's high-power fast charging development path and related standards; on the other hand, it comprehensively assists the rapid development of China's electric vehicle industry and contributes to the realization of China's grand goal of becoming an automobile power. the power of.

The overall development direction of electric vehicle charging piles   At present, the electric vehicle charging pile market is facing multiple difficulties such as the difficulty of handling old electric vehicle charging piles and the slow construction of new electric vehicle charging piles. However, the state still attaches great importance to the development of electric vehicle charging pile construction, and has repeatedly emphasized the determination to develop the new energy market in the recent 19th National Congress of the Communist Party of China. Among them, the construction of electric vehicle charging piles plays an important role in promoting the transformation of the country's energy structure, and will continue to receive attention and strong support. Analysis of the current development status of the electric vehicle charging pile market, in the 135 plan, the huge demand to meet the charging demand of 5 million electric vehicles by 2020 still stimulates the market development, but after the introduction of the new national standard for electric vehicle charging piles, new and old electric vehicle charging piles The replacement has not been implemented quickly, and the old electric vehicle charging piles are not only difficult to be compatible, but also face many difficulties, such as long-term unmanned use, aging equipment, failure of parts due to lack of maintenance, and the design of power supply equipment does not meet the current requirements of electric vehicle charging piles. Old electric vehicle charging piles can only be demolished and rebuilt. This undoubtedly increases the difficulty for the construction goal of building 4.8 million electric vehicle charging piles in five years.   Electric vehicle charging pile companies have begun to actively seek new development directions, and have strengthened their ties with new energy vehicle companies, parking lots, property departments, car rental companies, and power departments. The change in the awareness of the operation and service of electric vehicle groups has greatly improved the ability to guarantee the charging demand of electric buses in the public transportation system. The industrial structure of electric vehicle charging piles also needs to further strengthen the alliance, and predict market demand, improve the overall service awareness of the industry, and continuously adjust the product cost structure, strengthen resource integration, and improve the current price war market. The application rate of electric vehicle charging piles continues to increase, and it is imminent to strengthen the operation capacity of electric vehicle charging piles. Not only that, electric vehicle charging pile enterprises should keep abreast of relevant policy information issued by the government, and quickly understand the government's suggestions and favorable policies for the construction and operation of electric vehicle charging piles. At present, the government is in a period of favorable policies for the electric vehicle charging pile industry, but this time will not be long. If the subsidy opportunity is not seized in time, the government's subsidies for electric vehicle charging piles will continue to shrink in the future.

Why do the current new energy vehicle charging piles mainly use AC charging piles?   There are mainly the following reasons:   1. I think the most important thing is that the DC power output from the DC integrated charging pile is very large, hundreds of amps, which has a great impact on the life of the battery and may lead to a lot of reduction in the life of the battery. At present, the battery itself is the development of electric vehicles (even Including other equipment, such as mobile phones and other electronic products) bottlenecks. In other words, the current battery technology itself is not very perfect, if the battery life is often depleted, it is not economical enough.   2. The electric vehicle charging pile is convenient. It is installed in the parking lot or charging station. The input side only needs to be connected from the power grid. The output is also AC, and other equipment such as rectifiers are not required. The structure is simple.   3. Extending from the battery, the current electric vehicle is not suitable for long-distance driving, so in most cases, the electric vehicle can be charged slowly at work or at home at night.   4. The power of the AC charging pile is small, so the impact of electric vehicle charging on the power grid is also small. If the scale of electric vehicles is further increased in the future, if the DC high power is charged at the same time, the pressure on the power grid will increase. Of course, this It is also an issue that must be considered in the future.

The charging station is designed with distribution room, charger, charger back-ground management system, outdoor LED display, security monitoring system, monitoring room and rain shelter, etc. The overall design is coordi- nated and beautiful, with large distribution capacity, short charging time and more intelligent human-machine interaction. The 15 sets of 120KW DC char-ging piles used in the project are equipped with one machine and two guns, intelligent switching and multi-loop output performance, which can meet the requirement of 2 and a half hours for each charger at the bus station to fill 2buses.

With the gradual development of the new energy industry, more and more electric vehicles have appeared on the market. Today, I will introduce four common charging modes of car charger for you. Mode 1 Mode 1 charging technology refers to home charging from a standard power outlet with a simple extension cord. This type of charging involves plugging an electric vehicle into a standard household socket. This method of charging does not provide users with shock protection against DC currents. We do not recommend using this charging method.     Mode 2 Mode 2 charging involves the use of a special cable with integrated shock protection against AC and DC currents. In Mode 2 charging, the charging cable is provided with the EV. Unlike Mode 1 charging, Mode 2 charging cables have built-in protection in the cables which protects against electric shock. Mode 2 charging is currently the most common mode of charging EVs.     Mode 3 Mode 3 charging involves the use of a dedicated charging station or a home mounted wall box for EV charging. Both provide shock protection against AC or DC currents. In Mode 3, the connecting cable is provided with the wall box or charging station and the EV does not need a dedicated cable for charging. Mode 3 charging is currently the preferred means of EV charging.     Mode 4 Mode 4 is often referred to as ‘DC fast-charge’, or just ‘fast-charge’. However, given the widely varying charging rates for mode 4 – (currently starting with portable 5kW units through to 50kW and 150kW, plus the soon to be rolled out 350 and 400kW standards)
