The invention provides a vehicle battery power mapping relation correction method and device, equipment and a medium, and the method comprises the steps: obtaining an initial power mapping table, adjusting a vehicle battery to a test charge state, obtaining the corresponding test power based on the initial power mapping table, and setting the test power as the initial power mapping table; performing a discharge test on the whole vehicle battery based on the test power to obtain a test result, and correcting the initial power mapping table based on the test result to obtain a corrected battery power mapping relation; according to the method, the discharge state of the whole vehicle is tested according to the discharge power of the battery monomers, and the battery power mapping relation is corrected based on the test result, so that the corrected battery power mapping relation is more suitable for the use scene of the vehicle, and the battery power mapping relation is more suitable for the use scene of the vehicle under different charge states and environment temperature conditions. And the battery management system can accurately provide the required maximum power, so that the stability of the whole vehicle in the using process and the user experience are improved.
