Electrical Discharge System

Electrical discharge units are designed to safely reduce the state of charge of a battery by converting the stored chemical energy into heat—typically via resistive loads—or by feeding the energy back into the grid. The unit connects directly to the battery’s main terminals, often requiring access through the housing and potentially past safety features like contactors, fuses, and the Battery Management System (BMS).

Discharge is controlled through a pre-programmed logic that brings the battery to a defined safe voltage. Throughout the process, temperature monitoring is essential to ensure safe operation, especially in large-format batteries.
