Abstract
A charging control unit comprises a voltage detecting means including a first and a second resistor connected in series to an output of the armature coil, a third resistor parallelly connected to the second resistor and a temperature detecting element having a temperature coefficient, and a comparator having its one end connected to the second resistor and the other end connected to a reference voltage source. An arbitrary temperature characteristic can be set by varying the first resistor or the third resistor. At the same time, an arbitrary charging voltage can be set by changing the second resistor without changing the temperature characteristic.
