Abstract
A setting current switching circuitincludes a comparator. A battery temperature signal corresponding to a battery temperature detected by a battery temperature detecting unitis inputted to one input terminal (−) of the comparatorand a reference signal corresponding to a reference temperature is inputted to the other input terminal (+) of the comparatorto vary the setting charging current value of a charging current setting unitand the setting full-charge current value of a full-charge current setting unitcorrespondingly to the output of the comparator
