The technical specifications stipulate the safety requirements and test methods for lithium batteries for electric bicycles, both at single cell and battery pack levels. For single cells, six safety requirements have been considered: overcharge, over-discharge, external short circuit, thermal abuse, puncture, and marking. As for battery packs, the requirements mainly pertain to electrical safety, mechanical safety, environmental safety and thermal diffusion. The requirements also deal with data collection and marking.

The technical specifications only apply to lithium-ion batteries for electric bicycles with a maximum output voltage not exceeding 60V as stipulated in the “Electric Bicycle Safety Technical Specifications” (GB 17761). They do not apply to electric scooters, self-balancing vehicles, motorcycles, etc. Upon the implementation of the standard, all lithium-ion batteries for electric bicycles sold in China must meet these requirements.

Currently, the number of electric bicycles in China has exceeded 350 million. In 2023, enterprises above a nationwide designated size will produce a total of 42.28 million electric bicycles. Among the new electric bicycle models released by major domestic electric bicycle brands, more than 20% are equipped with lithium-ion batteries.

According to the Chinese Ministry of Industry and Information Technology, this mandatory national standard for the safety of lithium-ion batteries for electric bicycles and the technical specifications are of great significance to standardizing the design, production and sales of lithium-ion battery products for electric bicycles. They are aimed at improving product quality and safety levels and at promoting the development of the electric bicycle industry in a positive way.

This new Chinese standard is not relevant for batteries imported from China to the EU. These batteries must comply with EU rules and regulations as for instance ensuing from the new Battery Regulation. Furthermore, the EN-standards for EPACs, e-mountain bikes and for e-cargocycles also have requirements pertaining to the batteries.
