The invention discloses an electric automobile battery thermal management method, electronic equipment and an automobile. The method comprises the steps of responding to a whole automobile alternatingcurrent charging starting event; determining a first battery heating target temperature threshold value and AC rechargeable battery heating prediction time corresponding to the first battery heatingtarget temperature threshold value based on the lowest battery cell temperature of the battery at the AC charging starting moment; calculating a scale factor of the AC rechargeable battery heating prediction time and the AC charging prediction total time; determining a second battery heating target temperature threshold corresponding to the scaling factor; comparing the first battery heating target temperature threshold with the second battery heating target temperature threshold, and selecting the first battery heating target temperature threshold or the second battery heating target temperature threshold as a final battery heating target temperature threshold; and heating the battery to a final battery heating target temperature threshold. The service life (or the discharge capacity of the battery cell) of the battery cell and the alternating current charging time are considered, and thermal management is performed on the battery.
