This application provides a method for heating a battery and an apparatus for heating a battery. The method for heating a battery includes: determining, based on a battery temperature of a vehicle, an ambient temperature, and a meteorological temperature model, a wakeup moment that is before the battery temperature is lower than a first preset temperature threshold, where the meteorological temperature model describes a relationship in which an ambient temperature changes with moments; and controlling, at the wakeup moment, to heat the battery. Based on the method provided in this application, the battery can be heated when the battery temperature is about to be lower than the first preset temperature threshold, to reduce a quantity of vehicle wakeup times while a battery failure is avoided, thereby reducing heating power consumption of the battery.
