The invention discloses an electric vehicle battery pack capable of automatically adjusting temperature difference, which comprises a module on the outer side of a battery pack body and battery cellsstacked in the module, and is characterized in that the bottom of the module is connected with a liquid cooling plate in an attached manner, a cooling medium runner is arranged in the liquid cooling plate, and the top of the module is connected with a pulsating heat pipe in an attached manner; the pulsating heat pipe is in a snake shape, a groove matched with the pulsating heat pipe is formed in the top of the module, the pulsating heat pipe is arranged in the groove, and bubbles and liquid plugs are arranged on the pulsating heat pipe at intervals. According to the electric vehicle battery pack capable of automatically adjusting the temperature difference, the temperature difference in the battery pack module is improved by utilizing the pulsating heat pipe and the oscillation of the liquid plug while the liquid cooling plate is used for cooling and heat dissipation, and the liquid cooling is combined with the pulsating heat pipe, so that the heat dissipation of the battery does not adopt a single path any more, and the heat dissipation efficiency of the battery is improved; and the temperature of the battery cell is controlled within a proper working temperature range.
