The invention relates to the technical field of emergency protection circuit devices, in particular to a battery loop control device, a battery system and a battery loop control method. The battery loop control device comprises a first logic conversion circuit, an active safety driving circuit and a safety element, and the first logic conversion circuit is used for receiving a hardware abnormal signal; the output end of the first logic conversion circuit is electrically connected to the input end of the active insurance driving circuit, the output end of the active insurance driving circuit is electrically connected to the insurance element, and the insurance element is connected in series in a high-voltage loop; the first logic conversion circuit is enabled when receiving a hardware abnormal signal, the first logic conversion circuit outputs a first circuit driving signal to the active insurance driving circuit, and the active insurance driving circuit disconnects the insurance element. The battery loop control device can more reliably disconnect the high-voltage loop, and the risk and safety problems caused by the fact that the high-voltage loop cannot be disconnected are avoided.
本发明涉及紧急保护电路装置技术领域,特别涉及一种电池回路控制装置、电池系统以及电池回路控制方法。电池回路控制装置,包括第一逻辑转换电路、主动保险驱动电路和保险元件,第一逻辑转换电路用于接收硬件异常信号;第一逻辑转换电路的输出端电连接于主动保险驱动电路的输入端,主动保险驱动电路的输出端电连接于保险元件,保险元件串联于高压回路中;第一逻辑转换电路在接收到硬件异常信号时被使能,第一逻辑转换电路输出第一电路驱动信号至主动保险驱动电路,主动保险驱动电路使保险元件断开。电池回路控制装置断开高压回路更加的可靠,避免出现因无法断开高压回路而导致的风险和安全问题。
