The invention discloses a control method and device of a power battery, electronic equipment and a thermal management system, the control method of the power battery comprises the following steps: acquiring environment temperature and state parameters of the power battery, the state parameters comprising battery cell temperatures of a plurality of battery cells in the power battery; when it is determined that the power battery has the heating requirement according to the environment temperature and the state parameters, the target heating rate is determined according to the lowest temperature in the multiple battery cell temperatures; and determining a target inlet water temperature according to the target temperature rise rate, and performing temperature rise control on a thermal management system of the power battery according to the target inlet water temperature, so that the inlet water temperature of the power battery reaches the target inlet water temperature. According to the control method of the power battery, the water temperature of the request inlet can be dynamically corrected, the energy consumption in the charging process is reduced, the charging time is shortened, and meanwhile the calibration workload in the research and development process is reduced.

    本发明公开了一种动力电池的控制方法、装置、电子设备和热管理系统,动力电池的控制方法包括:获取环境温度和动力电池的状态参数,其中,状态参数包括动力电池中多个电芯的电芯温度;在根据环境温度和状态参数确定动力电池有加热需求时,根据多个电芯温度中的最低温度确定目标升温速率;根据目标升温速率确定目标入口水温,并根据目标入口水温对动力电池的热管理系统进行升温控制,以使动力电池的入口水温达到目标入口水温。该动力电池的控制方法可以动态的修正请求入口水温,降低了充电过程中能耗,缩短了充电时间,同时也降低了研发过程中标定工作量。
