Battery standards specify test methods and pass requirements for different levels of test objects. Generally speaking, Chinese vehicle battery safety standards divide the test objects into battery cells, battery modules, battery packs, and battery systems. GB 38031–2020 "Safety Requirements for Power Batteries for Electric Vehicles" [25 ...
The new standard for battery safety also deals primarily with “thermal accidents”. Among other things, it specifies that the thermal passage of a cell for five minutes must not cause a fire or explosion of the vehicle. This should give the occupants sufficient time to leave the vehicle.
Standards for electric vehicle (EV) batteries 18.2.1. Scope of a standard Standards for EVs have different scopes such as those addressing: (1) the energy system itself; (2) the application of the batteries, that is, the EV system; (3) the interfaces between the EV and power grids; and (4) the infrastructure.
The standards, which have been approved by the State Administration of Market Supervision and Administration and the National Standardization Management Committee will be implemented from January 1, 2021. The three standards are the first compulsory national standards in the field of electric vehicles in China.
The paper analyzes the development and shortcomings of the existing echelon utilization power battery standards system and proposes suggestions on the standards that urgently need to be improved, such as the electrical performance, safety performance, sorting and reorganization, and re-decommissioning of the echelon utilization power battery.
The most used standards are proposed and developed by testing facilities, battery producers, device integrators, car manufacturers, and governmental bodies; the standards are constantly reviewed to make sure they maintain relevance with technology developments and applications.
In the second group, the battery holds a large amount of energy and uses it in a mostly continuous fashion but at lower rates; this application corresponds to a battery electric vehicle (BEV) in which the battery is the only energy source for propulsion.

One of the standards relates to electric vehicles in general, another specifically to electric buses and the third to traction batteries.
BEIJING, June 21 -- China''s Ministry of Industry and Information Technology on Friday announced plans to formulate new standards for the global auto industry, focusing on new energy vehicles (NEVs) and intelligent connected vehicles.
Therefore, we say that there are currently five major charging standards worldwide. The five major standard interfaces are the Chinese standard based on GB/T 20234, the North American standard CCS1 based on J1772, the European standard CCS2 based on IEC 62196, the Japanese standard based on CHAdeMO, and the Tesla standard based on NACS.
Through experiments, the method can completely analyze the hexadecimal battery data based on the GB/T32960 standard, including three different types of messages: vehicle login, real-time information reporting, and vehicle logout. At the same time, the visualization method is used to intuitively and concisely analyze the factors affecting SOC. …
