On May 16, 2014, the 2014 International Electric Vehicles and Key Components Evaluation Seminar was held in Changzhou. Wang Fang, the chief expert in the battery field at the China Automotive Technology and Research Center, disclosed the progress of standardization of battery packs for electric vehicles. The first two items of the national standard “Lithium-ion battery pack and system test protocol for electric vehicles†have passed the review of high-power application test procedures and high-energy application test procedures. The third safety requirements test protocol is under solicitation for comments. After half a year of consultation is completed, a review will be submitted in mid-year or at the end of 2014.
The Electric Vehicle Subcommittee, which is responsible for the development of standards for electric vehicles, was established in 1998 under the National Automobile Standards Commission. The secretariat is located at the China Automotive Technology and Research Center. Wang Fang was responsible for or participated in the formulation of a number of national standards for power batteries for electric vehicles. The battery cells and modules and battery packs and system standards are formulated separately. With respect to the standardization of battery packs, the development progress is even faster. As mentioned earlier, the planned national standard is divided into: Part 1 of the Lithium-ion Power Battery Pack for Electric Vehicles and System Test Regulations. High-power applications, Part 2 High-energy applications. It was adopted in mid-January 2014. National Standardization Technical Committee review. Part 3 is currently soliciting comments. After comments are solicited in the first half of 2014, they will be submitted for review in mid-2014 or at the end of 2014.
With regard to the monomer and module of the power battery, the electric vehicle sub-committee converted it into a national standard based on industry standards such as “Lithium Ion Battery for Electric Vehiclesâ€, namely: “Technical Requirements and Test Method Safety for Power Battery for Electric Vehicleâ€, "Technical Requirements and Test Methods for Electric Vehicle Power Battery", "Technical Requirements for Power Battery for Electric Vehicles and Test Method Cycle Life". The first two national standards will be based on the revised version of the previous industry standard and will be integrated and separated; the third will be based on the industry standard opinion for the cycle life of the power battery. After the draft standard is formed, opinions will be sought in the standard setting working group. -4 weeks, after the revision, a public consultation draft will be prepared and it is planned to be reviewed in mid-2014. In addition, there is also a standard for the specification of power battery specifications for electric vehicles.
It will take some time to submit a review to become a national standard. According to the “Notice on Release of the Second Batch of National Standards Amendment and Implementation Plan for 2012†issued by the National Automotive Standardization Committee, the estimated completion time of the national recommendation for lithium-ion batteries for electric vehicles is 2015.
The national standard for power battery systems and individual batteries for electric vehicles has been left blank for a long time. The introduction of this series of national standards will regulate the production and operation of electric vehicles. Wang Dongdong, director of the Power Battery Laboratory at China North Vehicle Research Institute, told reporters that the requirements of the national standard are relatively basic. The battery that meets the national standard is not necessarily a good battery. The introduction of the national standard does not mean that China can build batteries. Prince Dong is also the director of the National Electric Power Vehicle's major special power battery test center for the "863" program. He said, "The key to power batteries lies in the efforts made by companies to do a good job of batteries, and corporate standards must be much higher than the national standard. The national standard requires 5 items. Experiments, you have 500 companies to do.â€
In addition to power batteries, there are still a large number of Chinese electric vehicle standards that are not yet completed. On May 15, 2014, at the same time in the 2014 international electric car and key parts assessment seminar, Wu Zhixin, deputy director of the China Automotive Research Center, was interviewed during the meeting and said that in five to eight years, the electric car standard (system) Get together. Wu Zhixin is also the chairman of the Electric Vehicle Sub-Technical Committee of the National Standardization Technical Committee.
