The invention relates to a battery pack heating framework, a battery pack heating method, a controller and a vehicle. The framework comprises a battery loop, and the battery loop comprises a battery pack; the battery water pump is connected with the water inlet of the battery pack; the integrated circuit comprises an integrated module integrating a vehicle-mounted charger and a direct current-direct current converter; the first communication module is arranged between the battery loop and the integrated loop, and the first communication module is used for connecting or disconnecting the battery loop and the integrated loop; and the controller is used for controlling the first communication module to communicate the battery loop with the integrated loop and controlling the battery water pump to work so as to heat the battery pack in response to the condition that the working state of the battery pack is in a non-heating state and the working temperature of the integrated module is not less than a first preset temperature when the battery pack is in a slow charging working condition. By adopting the scheme, the power consumption in the heating process of the battery pack can be reduced.
