The present application provides a heating circuit for a battery, a control method therefor, a battery, and an electric vehicle. A battery includes a first battery bank and a second battery bank, and the heating circuit for a battery includes a switch module, a heating module, and a control module. The switch module is connected to each of the first battery bank and the second battery bank. The heating module is connected to each of the first battery bank, the second battery bank, and the switch module. The control module is connected to each of the switch module and the heating module. The control module is configured to control the switch module to switch the battery to a heating state, and is configured to control the heating module when the battery is in the heating state, such that the first battery bank, the heating module, and the second battery bank form a loop. The loop is used to transfer electricity between the first battery bank and the second battery bank, so as to heat the first battery bank and the second battery bank. In this manner, the heating rate of the battery can be increased.
