Device description

Battery Module

Modular rechargeable battery used independently or as a building block of an energy storage system.

A battery module contains one or more electrochemical cells combined into a mechanically and electrically complete assembly. Multiple modules may be connected in series and/or parallel to obtain the required system voltage, power, and energy capacity.

Key parameters include usable energy capacity, maximum depth of discharge, charge and discharge C-rates, peak-discharge duration, and round-trip efficiency.

Operating limits include permitted charging and discharging temperatures and thermal-management requirements. Lifetime is characterized by cycle and calendar ratings with stated reference conditions.

Selection considers compatibility with BMS and inverter, expansion capability, electrical characteristics, lifetime, and compliance with IEC 62619 and IEC 63056.
