CTOnews.com, November 20, 2022 China Automotive Safety Conference opened today (20th) and will be held online today and tomorrow.

According to CCTV news, according to the new characteristics of road traffic accidents in China in recent years, the China Automotive Technology Research Center has announced a number of vehicle safety collision test projects with high complexity, such as simulating multi-vehicle traffic crashes, simulating two consecutive crashes, and truck roof pressing test.

In addition, with the rapid growth of the number of new energy vehicles in China, the electrical safety performance of new energy vehicles is particularly important. The China Automotive Technology Research Center has also added a number of rigorous tests, while the power outage of the high voltage system after the collision, no electrolyte leakage, no displacement of the battery pack, no fire, and no explosion will become the key safety assessment indicators of electric vehicles.

For example, in the high-speed rear-end collision test, it mainly examines the electrical safety protection function of the vehicle and the optimal structure of the third row of energy absorption space; in the tumble fall test, the test car at a speed of 60 km / h tumbles and falls from a unilateral bridge. The power battery located at the bottom of the electric vehicle will exert additional pressure on the top of the vehicle during the tumbling process.

In the water-related bottom test, the testers will send the electric vehicle to the flooded road and make it fall into the deep puddle of 30cm, so that the bottom battery pack will collide with the ground and the wall barrier in the water twice. this kind of test examines the requirements of the car company for electrical safety and waterproof performance of the battery package.

In the side column collision test, the CNAC examines whether the battery pack is prone to deformation and whether the electrolyte leakage causes a fire because the vehicle is out of control and crashes into pillars such as trees and telephone poles.

CTOnews.com reminded that the China Automotive Technology Research Center is a technical focal point unit of the automobile industry under the State-owned assets Supervision and Administration Commission of the State Council and a technical support organization for formulating automobile industry planning for the competent departments of the national government. The scientific research enterprise, which mainly assists the government in establishing and perfecting automotive industry standards and technical regulations, product certification and testing, quality system certification, industry planning and policy research, information services and soft science research, is also the management organization of C-NCAP.
