Abstract: A NiH/NiCd (nickel hydrogen/nickel cadmium) battery charger with the function of emergency power supply unit having a main body with a charging chamber and a charging circuit positioned within the main body to allow an electric connection to the charging chamber and the power input interface. This charging control circuit is controlled by an electrical switch which divides the charging chamber into two or more parts. When the power input interface is connected, the electrical switch shuts off automatically to make the batteries in the charging chamber to be charged in groups. This is the function of charger. When the power input interface is switched off, the batteries in different circuit are joined in series to supply power as an emergency power supply unit. Therefore, with the design principle of “separate charging and common sharing”, it can protect the rechargeable batteries and provide power in lacking of power supply unit outdoors.

Abstract: A serial charger with the function of automatic change of charging speed for NiCd/NiH batteries is provided where the different charging modes for multi-speed (four speed) charging process, two speed charging process or two speed charging process in two charging phases can be achieved by use of the speed-changing principle with a low power consumption of an exchange power unit. The finished charging time of each battery varies inversely as the number of the detected batteries to be charged. No matter whether the charging voltage is variable or constant, the charging current varies automatically to achieve the speedy charging process or the normal charging process even under low power consumption. Accordingly, an exchange power unit can be reduced in size and built in the charger so that the charger is convenient to carry and the finished charging time can be adjusted automatically according to the demand of battery consumption of customers.
