TEMPERATURE-RAISING DEVICE AND TEMPERATURE-RAISING METHOD FOR IN-CAR BATTERY
First Claim
1. A temperature-raising device for an in-car battery, the temperature-raising device comprising:
- a battery temperature acquisition unit configured to acquire a temperature of a battery mounted in a vehicle;
an environmental temperature acquisition unit configured to acquire an environmental temperature;
a heater configured to raise the temperature of the battery; and
a controller configured toi) turn ON or OFF the heater based on a result of a comparison between the battery temperature acquired by the battery temperature acquisition unit and a predetermined threshold, andii) reduce the threshold in accordance with a reduction in the environmental temperature acquired by the environmental temperature acquisition unit.
