1 Scope

GB/T 46443-2025 is the Chinese national standard covering the chiller that keeps a battery container within a few degrees end to end - the cooling and heating capacity across the ambient range, the temperature uniformity that decides how evenly the cells age, the redundancy, and the behaviour on a thermal event. First edition, in force from 1 May 2026. Issued on 31 October 2025, it has been in force since 1 May 2026.

This document specifies the types and basic parameters, technical requirements, inspection rules, and marking and packaging of refrigeration (heat pump) units for electrochemical energy storage. The requirements for loading, transportation, and storage are described, along with the corresponding test methods. This document applies to refrigeration (heat pump) units used in conjunction with the thermal management of electrochemical energy storage batteries employing vapor compression cycles, including air conditioners. Units and chilled/hot water units. Other similar units (such as those simultaneously supplying electrochemical energy storage batteries and their associated power modules and energy conversion modules, etc.) (For units that provide thermal management) Please refer to this guide.
