Abstract: When DC power to be supplied from a main power supply device drops and a voltage to be input to a load falls below a predetermined threshold value, a microcomputer controls a switch unit so as to start an ON-operation for supplying the DC power from a sub power supply device to the load, and when the DC power to be supplied from the main power supply device recovers, the microcomputer controls the switch unit so as to start an OFF-operation for restricting the DC power to be supplied from the sub power supply device to the load, restrict supply of the DC power from the sub power supply device to the load so that a voltage to be input to the load does not fall below a predetermined threshold value until a predetermined time has elapsed since start of the OFF-operation, and set supply of the DC power from the sub power supply device to the load to zero after the predetermined time has elapsed.

Abstract: A charging circuit includes a first power source circuit that supplies charging power to secondary batteries; a switch that controls the supply of the power; and a control device that performs switching control of the switch. The control device detects a voltage difference between the secondary batteries before starting charging; starts a timer and starts serial charging of the secondary batteries; on the condition that the voltage difference before the charging has been equal to or larger than a first threshold, if respective voltage values of the secondary batteries have both become equal to or larger than a second threshold before the timer expires, shortens a remaining time on the timer at that time point; and finishes the serial charging of the secondary batteries at the earlier of a time point when the secondary batteries have both become fully charged, or a time point when the timer has expired.
