CHARGE CONTROLLER AND NAVIGATION DEVICE FOR PLUG-IN VEHICLE
First Claim
1. A charge controller for charging a battery of a plug-in vehicle with a plurality of electric power sources including a solar photovoltaic generation system, the controller comprising:
- a driving route estimation element for estimating a next optimum driving route based on information, which an user input;
an estimated electric power consumption amount calculator for calculating an estimated electric power consumption amount, which is necessary to travel the next optimum driving route;
a weather information obtaining element for obtaining weather information until a next driving time;
a sunshine information obtaining element for obtaining sunshine information until the next driving time;
a solar photovoltaic generation electric power amount calculator for calculating a solar photovoltaic generation electric power amount until a next driving time based on the weather information and the sunshine information;
an electric power shortage amount calculator for calculating an electric power shortage amount when the solar photovoltaic generation electric power amount is smaller than the estimated electric power consumption amount;
a charge schedule preparation element for preparing a charge schedule, which represents a first charge time for charging the battery with the solar photovoltaic generation system and a second charge time for charging the battery by the electric power shortage amount with another electric power source; and
a charge control element for controlling to charge the battery according to the charge schedule.
