CHARGE CONTROL DEVICE AND VEHICLE LOADING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a charge control device, capable of reducing a total charging cost in consideration of power consumption requiring for putting in advance an energy storage unit in a state ready for charging.

SOLUTION: A charge control ECU17 computes a temperature-change time t2required for cooling or heating a battery by a cooler 13 or a heater 14 in consideration of a battery temperature. The charge control ECU computes a first power required for charge at a time when the charging time t1of the battery 2 is secured for a time from a charge-commenceable time to a vehicle starting time and a second power required for cooling or heating the battery 2 at the temperature-change time t2while using the time obtained by adding the temperature-change time t2to a present time as the charge-commenceable time. The cooler 13 or the heater 14 is controlled so that the total of electric rates converting the first power and the second power on the basis of an electric rate system having differences by time zones is minimized, and charging the battery 2 is carried out from an external power supply X.
