Abstract
A charging apparatus charges a plurality of rechargeable batteries individually and in succession. Each of the plurality of rechargeable batteries is coupled to one corresponding charging branch. The charging apparatus comprises a charging completion detecting circuit for detecting a charging completion of a rechargeable battery now in a charging operation, a high voltage detecting circuit for detecting an abnormal voltage of a charging branch now in a charging operation, wherein single pulse is generated responsive to the outputs of the charging completion detecting circuit and the abnormal voltage detecting circuit. A charging branch being connected to the charging voltage source is selectively and automatically switched responsive to the above described single pulse. Furthermore, the charging completion detecting circuit and the abnormal voltage detecting circuit are reset to an initial state responsive to the above described single pulse.
