GB/T 34131-2023

This standard specifies technical requirements, test methods, and safety protocols for battery management systems (BMS) used in large-scale electrical energy storage applications, such as grid-connected lithium-ion battery stations. It is applied to ensure accurate monitoring of voltage, temperature, and state of charge, as well as balanced cell management and fault protection in utility-scale storage systems. The standard is critical for manufacturers, system integrators, and grid operators to verify BMS performance under various operating conditions, including charging, discharging, and standby modes.
