ABSTRACT:
A novel power charger apparatus is provided for supplying electrical power to an electrical device for operation or to a battery for charging, or both. The charger apparatus comprises a primary power supply for supplying power from an external power source to the power charger, a power converter coupled to the primary power supply for converting the power received by the primary power supply from the external power source into a form usable by the power charger, and a power controller coupled to the power converter for controlling the power applied to the device or the battery, or both, whereby, regardless of the rate of charge of the battery, a constant current is maintained for charging the battery while the voltage across the device and battery is allowed to vary. To observe the rate of charge of the battery, the power charger also includes a charge rate sensor connected to the battery and coupled to the power controller to measure the voltage across the battery.
