IN-VEHICLE AUXILIARY POWER SUPPLY CONTROL DEVICE AND IN-VEHICLE AUXILIARY POWER SUPPLY DEVICE

摘要

The present invention more simply obtains a configuration with which the temperature of an auxiliary power supply can be increased even in a low temperature environment. In this in-vehicle auxiliary power supply control device (3), a control unit (10) can perform: charging operation in which a first switch unit (SW1) and a second switch unit (SW2) are brought into an on-state and an off-state, respectively; and discharging operation in which the first switch unit (SW1) and the second switch unit (SW2) are brought into the off-state and the on-state, respectively. An auxiliary power supply (7) is then raised in temperature by heat generation occurring in a resistor unit (22) by the charging and discharging operations performed by the control unit (10).
