Abstract:
1. A battery temperature control system that carries out temperature rise control to raise temperature of a battery mounted in a vehicle by periodically repeating charging and/or discharging of the battery, the battery temperature control system comprising: limiting means for limiting at least either of a cycle period or an amplitude of charging and/or discharging of the battery so that vibration noise and/or driving force fluctuation is reduced during execution of the temperature rise control; and vehicle speed detecting means for detecting vehicle speed, wherein the limiting means limits at least either the cycle period or the amplitude in accordance with the vehicle speed detected by the vehicle speed detecting means; wherein a limitation value of the at least either the cycle period or the amplitude is mitigated with an increase in the vehicle speed; and wherein the limiting means limits the amplitude based on both the cycle period and the vehicle speed.
