The present invention relates to a battery pack control device and method for repairing a relay failure, and aims to provide a method for repairing a temporary failure of a relay by re-checking the relay even when a relay failure is detected. To this end, the present invention comprises: a battery module comprising a plurality of battery cells; a relay through which an output current of the battery module is supplied or blocked; the current sensor is used for detecting the output current of the battery module; a voltage sensor that measures a voltage applied to both ends of the relay; and a processor that controls the relay to open and detects a state of the relay based on at least one of a current detected by the current sensor and a voltage measured by the voltage sensor, and that checks and repairs the relay when it is determined that the relay fails.
本发明涉及一种用于修复继电器故障的电池组控制装置和方法,并且旨在提供一种即使在检测到继电器故障时也通过重新检查继电器来修复继电器暂时失效的方法。为此,本发明包括:电池模组,该电池模组包括多个电池单体;继电器,通过该继电器供应或阻挡电池模组的输出电流;电流传感器,该电流传感器检测电池模组的输出电流;电压传感器,该电压传感器测量施加到继电器的两端的电压;以及处理器,该处理器控制继电器开路并基于由电流传感器检测的电流和由电压传感器测量的电压中的至少一个来开路检测、继电器的状态,并且当确定继电器失效时,该处理器检查并修复继电器。
