The invention relates to the technical field of automobiles, and provides a heat exchange system and method for an electric automobile, electronic equipment and a storage medium. The electric automobile comprises a power battery, an electric driving system and a braking resistor which are connected in parallel. The heat exchange system comprises a first heat exchange loop which is communicated with the electric driving system and the heat exchanger, and the first heat exchange loop is filled with lubricating oil; the second heat exchange loop is communicated with the brake resistor and the heat exchanger, and the second heat exchange loop is filled with cooling liquid; the heat exchange system has a lubricating oil heating state, in the lubricating oil heating state, the braking resistor is connected with the power battery, and the second heat exchange loop and the first heat exchange loop operate. According to the heat exchange scheme, under the low-temperature working condition, the braking resistor can be used for connecting the power battery for heating, lubricating oil of the electric driving system is heated, and therefore the problem that the electric driving system cannot normally operate under the low-temperature working condition due to the fact that the lubricating oil is too sticky can be solved without additionally arranging a heater.

    本发明涉及汽车技术领域,提供用于电动汽车的热交换系统、热交换方法、电子设备和存储介质。电动汽车包括并联的动力电池、电驱动系统和制动电阻;热交换系统包括:第一热交换回路,连通电驱动系统和热交换器,第一热交换回路中填充有润滑油;第二热交换回路,连通制动电阻和热交换器,第二热交换回路中填充有冷却液;热交换系统具有润滑油加热状态,于润滑油加热状态,制动电阻接通动力电池,第二热交换回路和第一热交换回路运转。本发明的热交换方案,在低温工况下,可以利用制动电阻接通动力电池发热,对电驱动系统的润滑油进行加热,从而无需增设加热器,即可解决低温工况下电驱动系统因润滑油过于黏稠而无法正常运转的问题。
