Research on Electric Vehicle Security To cover the full life cycle dynamic lithium-ion battery Recycling Renewal Requirement Director Wang Fang Wang Fang, Director Wang Fang, Director of the New Energy Laboratory of my country's Automobile Technology Research Center, at the 5th International Electric Vehicle and Key Component Assessment Seminar, I published the "Electric Vehicle Safety Regulations and Key Technology Development and Test Evaluation". She believes that the generalized electric vehicle safety should include manufacturing to transportation, from storage to use, from maintenance to the entire full life cycle. For electric car batteries to persist in sustainable development routes, the dynamic lithium-ion battery recycling and uses the development of the ladder to truly implement the implementation of green energy.
Wang Fang believes that the test of the safety of the vehicle is important including electrical control communication, electromagnetic compatibility, collision safety, function safety, and emergency rescue safety. First, the test of the safety of the vehicle is important including electronically controlled communication, electromagnetic compatibility, collision safety, function safety and emergency safety. Among them, electromagnetic compatibility is related to human protection, as well as integrated applications after intelligent networks; unlike traditional vehicles, the slight displacement and damage of the battery tank will affect the performance of the vehicle; in addition, the power lithium-ion battery is related to emergency rescue The trend of material three-dimensional, improved energy density makes thermal out-of control and thermal spread velocity control difficulty, and vehicle production and use of road transport should strengthen regulatory management, especially in summer rainstorm.
Second, charging security involves research and development and design of key components. Electric vehicle charging includes two parts of AC charging and DC charging, can be divided into four categories test requirements. The first is the charging connection device test, involving the plug and socket, etc.
; the second is a separate test of the automobile and charging pile, using special equipment to simulate the vehicle test charging pile, or simulate the charging pile test vehicle; third is the experimental vehicle and charging pile Car matching test; fourth is the actual matching test of on-site vehicles and charging piles, involving charging efficiency design in no-load and full load. Since the end of 2015 to 2016, the China Auto Center was tested in three batches of three batches, and the first 16 cars and 16 charging piles were first tested. The second is 20 cars and 11 charging piles.
The third time is 7 cars and 13 charging piles, including DC and AC charging matching tests, more than ten cities in the country will actually match the lives in various cities, which helps energy quality on the impact of charging efficiency. Third, the safety evaluation system of electric car battery. BMS security and fault diagnosis, battery pack shell protection IP level level anti-corrosion, anti-delay, anti-impact capacity is an important part of the national test standard.
In addition, the battery is safe, only if the battery is still effectively controlled in the thermostable control and thermal diffusion, in order to ensure system security. In the process of testing, the performance characteristics of the battery are very different. For example, after 65 degrees or 55 degrees, it is necessary to accurately determine the security level in the module and control the heat transfer process between the sub-module.
Fourth, the safety test evaluation system of power assembly. At present, the important basis for the industry is 18488 standards, and 28046 and other company standards, but there are still many defects in the actual evaluation process, including motor overheating, self-protection, insulated breakdown, sealed water problems. In promoting the development of industry development, the SMAC pays more attention to establishing a coherent test evaluation process from components to systems, in particular, involving the power assembly level, will cover the overall matching performance of the battery and motor system.
Fifth, sustainable development of electric car batteries. The recycling of the dynamic lithium-ion battery is imperative, especially in the safety hazard problem of long-term shelving electric vehicles. At present, there is no battery capacity to be less than 80% or 70%, but in fact, even if there is still a lot of remaining capacity, it is urgent to use reasonable utilization.
In addition, the secondary utilization of the power lithium-ion battery includes a system of operating monitoring, and the standardization and scale of the battery module. The system on battery operation monitoring, to perform overall design of the coding system of the battery, using the annual collection and accurate monitoring of the stage index parameters. The standardization and scale of battery modules is implemented, on the one hand, consider the versatility of the vehicle application, and on the other hand, consider the convenience of the ladder utilization site, to achieve better combination.
She proposed that the powerful lithium-ion battery recovery and re-uses the development of the ladder to truly implement the implementation of green energy.
