POWER SUPPLY, CHARGING CONTROLLER, CHARGING CONTROL METHOD, COMPUTER, AND ELECTRIC VEHICLE

摘要

PROBLEM TO BE SOLVED: To obtain a power supply deterioration of which can be suppressed surely at a low cost during storage, a charging controller and control method which can suppress deterioration of the power supply surely at a low cost during storage, and a computer and an electric vehicle applied with the charge control method. SOLUTION: A CPU 102, built into a main battery 64A, detects residual capacity of a battery 106 based on a current flowing through a resistor 108 and delivers a charge request to an embedded controller 80 in the inner circuit of a computer system 10, when the residual capacity drops below a predetermined suitable storage capacity of the battery 106. The embedded controller 80 controls a charger 68 charging the battery 106, in response to the charge request.
