Abstract:
A configuration can be more easily realized in which the temperature of an auxiliary power source can be increased even in a low temperature environment. In the in-vehicle auxiliary power source control device, a control unit performs a charging operation of switching a first switch on and switching a second switch off, and a discharging operation of switching the first switch off and switching the second switch on. Also, the temperature of an auxiliary power source is raised by heat generated by a resistor unit due to the charging operation and the discharging operation performed by the control unit.
