CHARGE CONTROL APPARATUS FOR VEHICLE
First Claim
1. A charge control apparatus for a vehicle, comprising:
- an electrically chargeable and dischargeable battery;
a battery heater that heats the battery;
a battery temperature detecting section configured to detect a temperature of the battery;
a battery control section configured to monitor the temperature of the battery and controlling the battery heater so as to heat the battery;
a battery charger that supplies electric power to the battery and the battery heater;
a timer charge reservation section configured to allow a user to designate a predetermined charge time zone and a target amount of electric power to be charged to the battery; and
a charge control section configured to determine a timer charge start time and carrying out timer charge when completion of the timer charge before elapse of a designated time is designated by the timer charge reservation section,wherein when the charge control section predicts that the timer charge and battery heating are simultaneously carried out, the charge control section determines a required amount of extension of a charge time period so as to complete charge of the battery before elapse of the designated time, and starts charge of the battery at a time advanced relative to the timer charge start time by the required amount of extension of a charge time period.

Abstract
When completion of timer charge before elapse of a designated time is designated by a timer charge reservation means for allowing a user to designate a predetermined charge time zone and a target amount of electric power to be charged to the battery, a timer charge start time is determined. Upon carrying out the timer charge, when it is predicted that the timer charge and battery heating are simultaneously carried out, a required amount of extension of a charge time period is determined so as to complete charge of the battery by the designated time, and starts charge of the battery at a time advanced relative to the timer charge start time by the required amount of extension of a charge time period. With this control, charge of the battery can be completed at a predetermined time without unnecessary enhancement in a required capacity of a battery heater.
