Why do we need a code for new energy vehicles?

One code realizes the traceability of the entire life cycle of power batteries. 1. Introduction China launched the national strategy of new energy vehicles (NEVs) in 2003 because of the shortage of fossil energy, the need of environmental protection and the adjustment and benefit of automobile industry.

What are the requirements of a battery manufacturer?

The manufacturer must draw up certain technical documentation. The manufacturer shall operate an approved quality system for the production, inspection and testing of the finished product and shall be subject to surveillance. This applies only to some types of batteries.

What are battery safety requirements?

These include performance and durability requirements for industrial batteries, electric vehicle (EV) batteries, and light means of transport (LMT) batteries; safety standards for stationary battery energy storage systems (SBESS); and information requirements on SOH and expected lifetime.

Are battery codes interoperable?

However, there are currently battery codes, car VIN codes, and recycling codes. The three-code coding rules are different and cannot be interoperable. Battery coding is the coding of battery packs/modules/cells individually by battery manufacturers in accordance with national coding rules [ 68] when power batteries are produced.

What is an example of a battery code?

For example, the battery code itself should be a one-dimensional code or two-dimensional code compiled for the purpose of managing information collection in the process of production, sales, use, scrapping, recycling, and utilization (to the comprehensive utilization enterprise) of power batteries.

What is a battery recovery code?

The battery recovery code itself is a series of numbers and letters combined with codes for managing power battery information collection during the collection, disassembly, classification, step utilization, metal recycling, resource regeneration, and waste disposal processes [ 70 ].
