A temperature increasing system for vehicle batteries includes a drive motor, first and second batteries, first and second temperature increasing units, and a controller. The drive motor can output a driving force for driving a drive wheel of a vehicle. The first battery can supply electric power to the drive motor. The second battery has a capacity smaller than a capacity of the first battery. The first and second temperature increasing units can increase, respectively, the temperatures of the first and second batteries by using electric power from the second battery. While the vehicle is parked, the controller heats the first battery by using the first temperature increasing unit if the temperature of the first battery is below a first value when the vehicle starts moving, and heats the second battery by using the second temperature increasing unit if the temperature of the second battery is below a second value.
