Wu Zhixin, deputy director of the China Automotive Technology and Research Center, said that since consumers' experience in the comprehensive performance of electric vehicles comes from all aspects, it is impossible to establish a test evaluation method that covers all performance indicators, so EV-TEST is currently only focused on the key performance related to the consumer experience. Such as the five areas of battery life, power consumption, charging, safety and power.
The specific evaluation method is that EV-TEST establishes a corresponding evaluation method according to the vehicle type grouping, considering the target consumer groups and usage scenarios of different types of electric vehicles. EV-TEST classifies electric vehicles into two groups: mini-vehicles, passenger cars less than 4m in length, regular cars, and passenger cars other than mini-vehicles. With the development of electric vehicle products and markets, the improved version grouping method of EV-TEST will be adjusted according to the situation.
In the cruising range, considering the complicated road conditions in China, the cruising range is divided into normal temperature and high temperature cruising range. In terms of power consumption, pure electric passenger car products, according to the different M quality, are fitted to the line of power consumption of 100 km under working conditions: Y=0.006×M+8.
In addition, EV-TEST evaluation in the charging aspect of a more detailed subdivision, taking into account AC charging compatibility, 100 km charging time, charging immunity; in DC charging, etc. have detailed scoring standards introduced. In terms of safety performance, wading and electric safety, human body electromagnetic protection, electromagnetic immunity, battery system waterproofing, etc. are included. In terms of power, the system evaluation will have more detailed scoring standards in the top speed, acceleration performance and other sub-items. The evaluation will also be graded according to the star rating, one to five stars, the higher the star rating, the better the overall performance of the model. The first evaluation results are scheduled to be released in the second half of this year.
