The invention provides a vehicle power battery thermal management method which comprises the following steps: in response to a charging starting instruction of a vehicle, determining a charging temperature interval of a power battery of the vehicle based on charging type information of the power battery of the vehicle, the charging temperature interval is the environment temperature required by the power battery under the charging type; acquiring current temperature information of a power battery of the vehicle; acquiring first current electric quantity information of a power battery of the vehicle in a normal charging state; and when it is determined that the first current electric quantity information of the power battery is larger than or equal to the target electric quantity information and the current temperature information of the power battery is within the charging temperature interval, the power of high-power temperature stabilizing equipment in the vehicle is reduced, and a temperature stabilizing water pump of the vehicle is controlled to be started. Therefore, the vehicle temperature-stabilizing water pump is started in advance before charging is finished, so that the energy consumption can be reduced and the service life of the battery can be prolonged under the condition of ensuring normal charging.

    本发明提供了一种车辆动力电池热管理方法,包括:响应于车辆的充电开启指令,基于所述车辆的动力电池的充电类型信息,确定所述车辆的动力电池的充电温度区间,其中,所述充电温度区间为所述动力电池在所述充电类型下所需的环境温度;获取所述车辆的动力电池的当前温度信息;获取所述车辆的动力电池处于正常充电状态下的第一当前电量信息;在确定所述动力电池的第一当前电量信息大于或等于目标电量信息,且动力电池的当前温度信息处于所述充电温度区间的情况下,降低所述车辆中大功率稳温设备的功率,且控制所述车辆的稳温水泵的开启。这样,通过在结束充电前提前开启车辆稳温水泵,可以在保证正常充电的情况下,降低能耗,提高电池的使用寿命。
