Abstract
Even when a transient decrease has arisen in a battery voltage VBAT of a battery pack at startup of a motor that drives a flywheel, a power terminal Vcc and a reset terminal RES (or an input terminal IN of a reset IC) of a microcomputer are replenished with a normal voltage by the voltage accumulated by a capacitor of the backup power circuit, and hence a controller can maintain normal operation without involvement of faulty operation. As a result, even the battery pack whose battery has a smaller amount of remaining energy can be effectively utilized as the power source of an electric driving machine.
