GB 48146-2026Technical conditions of lithium-ion traction battery applied in underground mine (English PDF)

GB 48146-2026 is the English-translated version of 地下矿山用锂离子动力电池技术条件.

Technical conditions for lithium-ion traction batteries used in underground mines are given in this mandatory national standard.

Because these batteries power mine vehicles and equipment in confined, hazardous workings, the document matters to battery manufacturers, makers of electric mining vehicles, mine operators and safety regulators who must decide whether a battery product is acceptable for underground use.

It was issued on 27 August 2026 under the responsibility of the National Mine Safety Administration and takes effect on 1 March 2027. As a GB standard it is mandatory in China, so products intended for underground mines there need to be assessed against it.

Buyers who supply or purchase power systems for mine locomotives, trackless vehicles and similar equipment will find it a useful reference when preparing technical specifications and compliance files.

No predecessor document is identified for it in the available data, and readers should consult the full text for its detailed content.
