摘要： To reduce power consumption when charging a secondary battery is not performed, a first power supply circuit is disabled but a second power supply circuit is enabled when the secondary battery is unloaded from a battery charger. Both the first and second power supply circuits are enabled when the battery is loaded in the charger The first power supply circuit is provided for supplying power to the secondary battery. The second power supply circuit is provided for supplying a first voltage to such components that are operated with the first voltage and a second voltage to such components that are operated with the second voltage, wherein the second voltage is greater than the first voltage. When the battery is unloaded from the charger, the second power supply circuit supplies only the first voltage whereas when the battery is loaded in the charger, the second power supply circuit supplies the first and second voltages to the corresponding components.
