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.
