The invention discloses a battery control method, a vehicle-mounted controller, a battery control system and an automobile. The method comprises the following steps: acquiring a current state of a battery pack and actually measured data corresponding to the current state; determining a low-temperature power limit value and a high-temperature power limit value of the battery pack based on the current state and the measured data; determining the smaller one of the low-temperature power limit value and the high-temperature power limit value as a target power limit value of the battery pack; and controlling the battery pack to work based on the target power limit value. According to the method, the current state of the battery pack and the measured data corresponding to the current state are considered, the low-temperature power limit value and the high-temperature power limit value corresponding to the current state are compared, the target power limit value corresponding to the current state is determined, the minimum power limit value of the battery pack can be accurately determined, and the method has high application value.

    本发明公开了一种电池控制方法、车载控制器、电池控制系统和汽车。该方法包括:获取电池包的当前状态和当前状态对应的实测数据;基于当前状态和实测数据,确定电池包的低温功率限值和高温功率限值;将低温功率限值和高温功率限值中的较小值,确定为电池包的目标功率限值;基于目标功率限值,控制电池包工作。该方法将电池包的当前状态和当前状态对应的实测数据考虑在内,对当前状态对应的低温功率限值和高温功率限值进行比较,确定当前状态对应的目标功率限值,能够较为精确地确定电池包的最小功率限值,具有较高的应用价值。
