1. A heating control method for a vehicle including a battery and an air conditioner that enables to heat a vehicle compartment, the vehicle being capable of traveling by electric power of the battery, including:
an outside-air-heat absorption mode in which the vehicle compartment is heated by absorbing heat from outside air without absorbing heat from the battery; and
a battery-heat absorption mode in which the vehicle compartment is heated by absorbing heat from at least the battery,
wherein the heating control method comprises:
heating the vehicle compartment in the battery-heat absorption mode when the operation of the air conditioner is started; and
after the battery-heat absorption mode is selected and an operation of the air conditioner is started, switching from the battery-heat absorption mode to the outside-air-heat absorption mode, or reducing an amount of heat absorbed from the battery in the battery-heat absorption mode, at a time when a temperature decrease amount of the battery since the start of the operation of the air conditioner is equal to or larger than a predetermined temperature decrease amount.
