The present application discloses a thermal management method for a battery pack. The method includes: under a condition that an electric vehicle is in a stationary state, obtaining a power-on time of the battery pack in the electric vehicle; under a condition of determining that the battery pack has a thermal management demand, determining a target temperature of the battery pack according to a connection state of a charging interface of the electric vehicle and a charging device; determining a thermal management starting time of the battery pack based on the target temperature of the battery pack and the power-on time; and under a condition that the thermal management starting time arrives, performing thermal management on the battery pack so that a temperature of the battery pack reaches the target temperature before the power-on time arrives.
