On May 12, GB 18384-2020 “Electric Vehicle Safety Requirements” and GB 38031-2020 “Electric Vehicle Safety Requirements” and GB 38031-2020 “Electric Vehicle Safety Requirements”, which were organized by Hongye and the Ministry of Information Technology, led by China Automotive Technology Research Center Co., Ltd., and participated by key enterprises such as BAIC New Energy Safety Requirements for Using Power Batteries”, approved and issued by the State Administration for Market Regulation and the National Standardization Administration. As the first batch of mandatory national standards for electric vehicles, it will be implemented from January 1, 2021.
As a key domestic new energy vehicle enterprise, BAIC New Energy has been the sales champion in the domestic pure electric vehicle market for seven consecutive years. With its deep technical accumulation and strength reserves in the new energy vehicle field for ten years, it has deeply participated in two mandatory national standards for electric vehicles. The formulation.
As a national strategic emerging industry, new energy vehicles have developed by leaps and bounds in terms of technological level, industrial scale, and market acceptance in the past ten years. In order to implement the requirements of the “Energy-saving and New Energy Automobile Industry Development Plan (2012-2020)”, “Mid- and Long-term Development Plan for the Automobile Industry” and other requirements, combined with the actual development of the new energy automobile industry and the needs of technological progress, the Ministry of Industry and Information Technology launched in 2016 Establishment of strong standards for electric vehicle safety. The strong standard for electric vehicles is a synthesis of the technological innovation achievements and experience summary of my country’s electric vehicle industry, fully coordinated with international standards and regulations, and further improved and optimized the safety technical requirements for electric vehicles and power battery products. In the “Electric Vehicle Safety Requirements”, it mainly stipulates the electrical safety and functional safety requirements of electric vehicles, and increases the battery system thermal event alarm signal requirements; strengthens the vehicle waterproof, insulation resistance and monitoring requirements to reduce the normal use of the vehicle Safety risks in situations such as wading and wading; test methods such as insulation resistance and capacitive coupling have been optimized to improve the accuracy of test detection and ensure the safety of the entire vehicle’s high-voltage electricity.
The “Safety Requirements for Power Batteries for Electric Vehicles” fully considers users’ extreme usage scenarios, and adds a number of test items corresponding to various extreme scenarios, such as: post-vibration immersion test to verify the waterlogging encountered by users during the entire life cycle Under the environment, whether the sealing of the battery pack is abnormal and whether there will be insulation problems; the overcurrent protection test simulates the safety protection of the battery pack when the current exceeds the limit due to the fault of the charger, so as to avoid exceeding the normal use conditions of the battery and causing safety problems; The thermal diffusion test simulates extreme cases of thermal runaway in a battery cell inside the battery pack, and the battery system does not catch fire or explode within 5 minutes. At the same time, an alarm signal requirement is added to the “Electric Vehicle Safety Requirements”, which can be the first time Give safety reminders to drivers and passengers and reserve a safe escape time for passengers.
In recent years, with the advancement of battery and vehicle technology, the driving range of new energy vehicles has no longer become a pain point for users, safety issues have become increasingly prominent, and battery thermal runaway has become a technological challenge for the entire industry. At present, most of the new energy vehicle companies have established safety requirements, performance requirements and test methods in all technical fields such as complete vehicles, energy consumption, charging and swapping, electromagnetic compatibility, batteries, and motors, and have established a scientific and reasonable standard system. The implementation of the two national mandatory standards further clarifies corporate responsibilities, which will be of great significance for improving the safety of new energy vehicles and ensuring the healthy and sustainable development of the industry. It is believed that with the implementation of national mandatory standards and the improvement of battery-related technology, the safety of electric vehicles in the future will be finally solved. According to industry insiders, the two mandatory standards reflect the country’s gradual transition from “policy-driven” to “market-driven” in the process of industrialization of new energy vehicles, becoming more market-oriented and effectively linking user needs. These requirements will have far-reaching effects and significance at the level of users, wheels, battery suppliers, and battery cell suppliers, and will promote technological progress in my country’s new energy vehicle battery safety and collision avoidance design to a certain extent. Improve the international status of my country’s new energy vehicle products and standards.
As a leading company in the domestic new energy vehicle industry, BAIC New Energy has made safety the top priority of electric vehicles in the development process. It has now completed the establishment and implementation of vehicle electrical safety corporate standards, test specifications, and test cases. In addition, on the basis of the electric vehicle safety standard requirements, through technical exchanges with experts and scholars in various professional fields, learn from relevant domestic and foreign standards, technical requirements and test specifications, put forward higher and more comprehensive requirements for the practical application of electric vehicles, and maximize Ensure product safety and reliability. Up to now, BAIC New Energy has won the first place in user satisfaction of new energy vehicles by CACSI China Quality Association for five consecutive years.” The total mileage of its new energy vehicles exceeds 12.1 billion kilometers, which is equivalent to 300,000 laps around the earth’s equator, which is fully verified Its advancement and reliability in the field of electric vehicle safety.
In July last year, BAIC New Energy established a new energy vehicle test center with industry benchmark significance. The test center has an area of ??about 50,000 square meters, 88 laboratories and more than 400 sets of international advanced test equipment. Among them, the investment in battery-related test equipment exceeded 140 million yuan, which fully guarantees product performance verification. In the future, BAIC New Energy will continue to optimize and improve, form a full-scene electrical safety standard system and test specifications for charging safety, battery replacement safety, driving safety, operational safety, etc., and continuously strengthen the development and verification of electrical safety in the vehicle development and verification process , Escort the safety of the entire vehicle.
