The embodiment of the invention discloses a battery manager. The battery manager comprises an auxiliary power supply control module, a battery voltage detection module, a system power supply control module, a central control module and a power supply module, the battery voltage detection module is used for detecting the battery voltage of the storage battery when the auxiliary power supply control module is self-locked; the central control module is used for controlling the system power supply control module to disconnect with the negative electrode of the whole vehicle system when the battery voltage is smaller than a first threshold value. Or the central control module is used for controlling the auxiliary power supply control module to release self-locking when the battery voltage is greater than a second threshold value; the auxiliary power supply control module is used for controlling the power supply module to stop supplying power to the system power supply control module when self-locking is relieved; the system power supply control module is used for disconnecting with the negative electrode of the whole vehicle system after power failure. According to the scheme, the storage battery can be monitored in real time, and the storage battery is prevented from being overcharged or overdischarged.
本发明实施例公开了一种电池管理器。该电池管理器包括辅助电源控制模块、电池电压检测模块、系统供电控制模块、中央控制模块以及电源模块;电池电压检测模块用于在辅助电源控制模块自锁时检测蓄电池的电池电压;中央控制模块用于在电池电压小于第一阈值时控制系统供电控制模块断开与整车系统负极的连接;或,中央控制模块用于在电池电压大于第二阈值时控制辅助电源控制模块解除自锁;辅助电源控制模块用于在解除自锁时控制电源模块停止给系统供电控制模块供电;系统供电控制模块用于在断电后断开与整车系统负极的连接。本方案可以对电池蓄电池进行实时监控,防止蓄电池出现过充或过放。
