Abstract:
1. A NiH/NiCd (nickel hydrogen/nickel cadmium) battery charger with the function of emergency power supply, comprising: a) a main body having a charging chamber for accommodating a plurality of batteries; b) a power input interface positioned at one side of the main body and attached to a mains socket; and c) a charging control circuit positioned within the main body to allow an electric connection to the charging chamber and the power input interface, the charging control circuit including: wherein, when the power input interface is electrically loaded, the N-MOSFET of the electrical switch is switched on while the P-MOSFET thereof is switched off so that the batteries in the charging chamber are automatically separated for an individual charging process, thereby forming a type of charger; and wherein, when the power input interface is electrically unloaded, the N-MOSFET of the electrical switch is switched off while the P-MOSFET thereof is switched on, so that the batteries in the charging loops are automatically connected to supply required power via an emergency power supply interface to electronic units, thereby forming a type of an emergency power supply unit.
