US 2024/0186597 A1 · DEVICE AND METHOD FOR DISCHARGING BATTERY

Abstract

A battery discharge device is disclosed. The battery discharge device comprises: a discharge circuit connected to a battery module; a sensor unit configured to measure a state of the battery module, the sensor unit connected to at least one of the discharge circuit or the battery module; and a control unit configured to obtain information on the state of the battery module from the sensor unit, wherein the discharge circuit includes: a terminal unit having a first terminal unit and a second terminal unit, the first and second terminal units being electrically connected to the battery module; and a first electric circuit electrically connected to the first and second terminal units, wherein the control unit is configured to determine whether the battery module operates normally, based on the information on the state of the battery module.
