BATTERY TEMPERATURE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a battery temperature control device which inhibits electric power consumption needed for temperature control of a battery after an ignition is turned off thereby preventing the battery exhaustion.SOLUTION: A battery temperature control device 10 includes: temperature control means 12 performing cooling and heating of a battery module 11; environmental temperature detection means 13 detecting an environmental temperature; and a control device 14 which starts the control of the temperature control means 12 on the basis of the environmental temperature detected by the environmental temperature detection means 13 at the timing when an ignition is turned off so that a difference between a battery temperature and the environmental temperature becomes large. The control device 14 controls the temperature control means 12 for a predetermined time which is preset corresponding to the difference between the battery temperature and the environmental temperature.
