The invention discloses a power battery thermal management method and device, equipment and a storage medium. The method comprises the steps that a current power battery request signal in an electric vehicle is acquired; under the condition that the power battery request signal is a power battery heating request signal, determining first unit energy consumption and second unit energy consumption according to the power battery heating request signal and a passenger compartment heating request signal, the thermoelectric effect module is controlled by the power battery control unit to heat the power battery according to the first unit energy consumption and the second unit energy consumption; and under the condition that the power battery request signal is a power battery refrigeration request signal, the thermoelectric effect module is controlled by the power battery control unit to refrigerate the power battery according to the power battery refrigeration request signal and the external environment temperature. According to the invention, the self-balance of the temperature of the power battery is realized, and the energy consumption in the thermal management process of the power battery is reduced.

    本发明公开了一种动力电池热管理方法、装置、设备及存储介质,所述方法包括:获取电动汽车中当前的动力电池请求信号;在动力电池请求信号为动力电池加热请求信号的情况下,根据动力电池加热请求信号和乘员舱加热请求信号,确定第一单位能耗和第二单位能耗,并根据第一单位能耗和第二单位能耗采用动力电池控制单元控制热电效应模块对动力电池进行加热;在动力电池请求信号为动力电池制冷请求信号的情况下,根据动力电池制冷请求信号和外界环境温度采用动力电池控制单元控制热电效应模块对动力电池进行制冷。本发明实现了动力电池温度的自均衡,减少了动力电池热管理过程中的能量消耗。
