Abstract
An electric junction box is equipped with a special simplified power supply. An internal circuit of the electric junction box supplies the output of the simplified power supply as an operating voltage of a DC/DC converter to start the DC/DC converter when battery exhaustion occurs in the low voltage battery. When the DC/DC converter is started, high voltage power stored in a high voltage battery on the vehicle can be stepped down and supplied to a circuit on the low voltage battery, thereby enabling normal starting operations such as starting an engine. An emergency start mode can be selected by a switch operation of a user or by automatic detection of a drop in power supply voltage.
