Vehicular electric charge control apparatus and emergency notification system
First Claim
1. An electric charge control apparatus for a vehicle having a backup battery, which is a secondary battery for supplying electric power to in-vehicle devices mounted in the vehicle in case of emergency, the electric charge control apparatus comprising:
- a residual charge amount monitor unit that monitors a residual charge amount of the backup battery;
a time information acquisition unit that acquires present time information indicating a present time;
a time-divided temperature information storage unit that stores time-divided temperature information, which indicates a temperature in each predetermined period at a battery location of the backup battery;
a charge/discharge amount determination unit that determines a charge/discharge amount of the backup battery based on the time-divided temperature information and the residual charge amount, the time-divided temperature information being acquired based on the present time information and the time-divided temperature information; and
a residual charge amount control unit that controls the residual charge amount of the backup battery by charging and discharging the backup battery in accordance with the charge/discharge amount determined by the charge/discharge amount determination unit.

Abstract
A charge control apparatus includes a main control unit and a power source control unit. The main control unit acquires time-divided temperature information, which corresponds to a predetermined period covering the present time, based on present time information and the time-divided temperature information indicating a location temperature of a backup battery in each predetermined period. The main control unit determines a charge/discharge amount of the backup battery based on the time-divided temperature information and a residual charge amount of the backup battery. The power source control unit controls the backup battery by charging and discharging in accordance with the determined charge/discharge amount.
