Abstract
A vehicle power supply device includes a relay controller. When a low voltage switching request is made to set a mode for supplying electric power from a switching module group to a low voltage power supply, the relay controller is configured to perform in sequence a first process of switching a first main relay and a second main relay to an open state, a second process of connecting a first switching relay to a second electrode terminal of the low voltage power supply and switching a second switching relay to a closed state, a third process of switching a precharge relay to a closed state and switching a third switching relay to a closed state, a fourth process of switching the second main relay to a closed state, and a fifth process of switching the precharge relay to an open state.
