According to the rapid heating control strategy for the power battery, the corresponding battery heating strategy is executed according to different detected charging scenes and battery temperatures, so that the heating effect better conforms to the working condition, the energy loss and the fault rate are reduced, the fault is detected before the battery heating function is started, heating is executed in a fault-free state, and the heating efficiency is improved. The power of other high-voltage loads is controlled before the heating loop is started, so that circuit fusing is prevented, the corresponding heating power is matched according to different charging scenes and battery temperatures, the heating efficiency is improved, and the energy consumption is reduced. Besides, according to the power battery rapid heating control strategy, a plurality of safety thresholds are set, signals such as current, voltage, temperature and capacity are detected in real time in the operation process of the heating function, and heating is stopped immediately when the signals exceed the thresholds, so that the safety of the heating process is ensured, and the safety risk is reduced to a great extent.

    一种动力电池快速加热控制策略,根据检测到的不同充电场景和电池温度,执行相应的电池加热策略,使加热效果更符合工况,且减少能量损耗和故障率,通过在电池加热功能启动前检测故障,确保在无故障状态下执行加热,通过在启动加热回路前控制其它高压负载的功率,以防止发生电路熔断,根据不同充电场景和电池温度匹配对应的加热功率,提高了加热效率,减少能耗。另外,本发明的动力电池快速加热控制策略还设置了多个安全阈值,在加热功能运行的过程中,实时检测电流、电压、温度和容量等信号,在超出阈值时立即停止加热,以确保加热过程的安全性,极大限度地降低了安全风险。
