The invention discloses a method and device for correcting SOH based on a big data platform, electronic equipment and a medium. The method comprises the following steps: acquiring the maximum allowable charging power, the maximum allowable discharging power and the current residual electric quantity of a current value when a power battery of a target vehicle works; calculating the high-power charging and discharging times of the power battery according to the maximum allowable charging power and the maximum allowable discharging power to obtain target charging and discharging times; according to the current residual electric quantity, calculating the deep discharge frequency of the power battery to obtain a target deep discharge frequency; according to the current value, calculating the number of cycles of the battery to obtain a target number of cycles of the battery; and correcting the current SOH of the target vehicle by using the target charge and discharge times, the target depth discharge times, the target battery cycle times and predetermined vehicle data to obtain a target SOH. According to the technical scheme, the adaptability to different driving habits is high, the SOH precision of the power battery is greatly improved, and the service life of the power battery is prolonged.
