with the explosive growth in sales of new energy electric vehicles, related safety hazards and challenges have gradually emerged, such as safety issues of the battery system during charging and discharging, the risk of power system loss of control, power safety in water-related scenarios, and the risk of thermal runaway of batteries. these safety issues not only affect consumer trust, but may also pose a threat to the continued healthy development of the industry. therefore, ensuring the safety of new energy vehicles in various usage scenarios has become a core issue that the industry must prioritize. in response to this, china automotive research institute and authoritative institutions have established a relevant working group, starting from the two aspects of electrical safety and fire safety unique to new energy vehicles, and launched the "new energy vehicle safety new quality evaluation (nevs-nqe)" certification procedure, and based on this, conduct testing and evaluation.

(electrical safety and fire safety can be certified separately)

(after passing both electrical safety and fire safety, you can obtain the all-round star certification)

we pay special attention to three core areas: driving difficulties in bad weather, daily anxiety points for car owners, and safety risks that may be caused by misoperation. we conduct rigorous tests from multiple key dimensions to ensure that new energy electric vehicles can demonstrate stable and reliable performance when facing various challenges in vehicle use. as an authoritative third-party testing agency, we ensure the professionalism and fairness of the test results, and also provide companies with a platform to showcase their technological innovations and product advantages.

some time ago, some cities in my country were hit by heavy rainfall due to the impact of typhoon makar. heavy rainfall and the resulting waterlogging on the road and soaking of the battery packs are extremely likely to threaten the safety of drivers' lives and property. in this regard, the electrical safety test deeply restores dangerous scenarios such as heavy rain, deep potholes on the road, and soaking of the whole vehicle, which endanger the electrical safety of the whole vehicle and challenge the waterproof performance of the whole vehicle. the test examines the waterproof ability of the whole vehicle after scraping and supporting the bottom, and whether it affects normal driving.

the electric vehicle safety test is based on the accident scenario library, and is designed to test the vehicle power system faults, especially for high-speed driving conditions. the test aims to examine the vehicle's recognition and response mechanisms in various fault situations, and whether the vehicle can issue timely warnings when the user makes a mistake and help the user make the right decision based on the decision-making and control capabilities of the vehicle computer.

fire safety mainly focuses on the impact of electrolyte leakage, fire, explosion and electric shock caused by thermal runaway of power batteries on personal safety. thermal runaway is triggered by internal heating or bottom puncture, and the alarm time of fire, heat diffusion speed, smoke and toxic gas content, and destructiveness of explosion are monitored. the hazard of vehicle fire accidents is scored and the fire safety level is divided.

after rigorous testing and strict evaluation, xinghai s7, avita 07 and deep blue s07 passed the electric vehicle electrical safety assessment procedures and obtained the electric vehicle electrical safety star certificate issued by china automotive research institute kerry certification. at the new energy vehicle fire safety and electrical safety technology forum held on september 20, xia guoqiang, director of the china automotive research institute standard certification center, presented awards to the winning units.
