With the formal introduction of the "Notice on Continuing the Promotion and Application of New Energy Vehicles" on September 17, 2013, the development of new energy vehicles ushered in a new round of development opportunities. As the mainstay of new energy vehicles, electric vehicles are always the type of subsidies that receive the most “careâ€. Even so, the high cost, difficulty in charging and poor battery life are still the three major bottlenecks for electric vehicles failing to open the market quickly. Chengdu LianTeng Power Control Technology Co., Ltd. is an integrated provider of electric vehicle system solutions and a key component development and powertrain system integrator with strong innovation capabilities in the southwest region. In 2013, it took the lead in uniting the Chengdu Bus and Dongfeng Motor. , Electronic Science and Technology, Noble Science and Technology and other cooperative units undertook the provincial major science and technology support program “Development of Electric Vehicle Power System†and recently made gratifying progress in breaking through the three major bottlenecks in the development of electric vehicles. First, the development of AC dual induction permanent magnet synchronous motor. The company and the Ukrainian Electro-Research Electrodynamics Laboratory (EDL) and the Lakatosh Valentin Pavlovich academician team conducted a joint tripartite research. This project is one of the company's key scientific research projects in 2014 and has now completed the development of the prototype. Into the actual measurement work, the power density of up to 10.4kW/kg, torque density of up to 51.5Nm / L, indicators exceed the current domestic leading level 3.0kw/kg, reached the international advanced level, is expected to enter the loading phase in September. Second, battery energy efficiency management system development. The second major scientific research project jointly developed by the company and the Scientific-research Electrodynamics Laboratory (EDL) of Ukrainian Electro-dynamics Technology Laboratory can effectively increase the energy usage rate of the battery and enable the current development of electric vehicles to break through the bottleneck of limited battery energy density. Changan Ruixin equipped with a 300kg battery that was controlled by the system had completed a 480km road test for continued driving mileage. 3. The on-vehicle ultra-high power charging device is independently researched and developed by the company. It can directly use the AC 380V standard AC power socket for rapid charging. Combined with unique battery grouping technology, it can achieve up to 90% of the 30-minute power charge. At the same time compatible with the existing charging equipment and home 220V charging mode. The above three transformational technologies have fundamentally solved the problems of vehicle cost, cruising range, and bottlenecks in the development of electric vehicles due to the large investment in basic charging facilities and construction difficulties, which are driving the development of the industry and industrial chain. The new energy electronic control and powertrain system is a core component of the electric vehicle industry. It plays a role in the supply chain (batteries and battery materials) in the industrial chain and is the core competitiveness of new energy vehicles. Technology has the important significance of driving the development of local related industries and technologies. In the next few years, the company will expand the field of international technology cooperation and will involve technology exchanges and introduction of key technologies in the electric vehicle industry chain, such as battery manufacturing technology, battery Material technology, and high-power semiconductor technology, to make new energy automotive industry development for the province. contribution.
