VEHICLE-MOUNTED POWER SOURCE DEVICE

WIPO Patent Application WO/2019/093289

A1

This vehicle-mounted power source device is provided with an electricity storage unit, a charging unit, a discharging unit, and a control unit which controls the operation of the charging unit and the discharging unit in accordance with an activation signal. When the control unit receives the activation signal, a terminal voltage of the electricity storage unit is brought to a first voltage by means of a charging operation of the charging unit, and when the control unit stops receiving the activation signal, the discharging unit begins a discharging operation and the terminal voltage of the electricity storage unit drops to a second voltage lower than the first voltage. When the terminal voltage of the electricity storage unit drops below the second voltage, or when a prescribed length of time has elapsed after the terminal voltage of the electricity storage unit drops below the second voltage, the charging unit applies a third voltage lower than the second voltage to the electricity storage unit until the control unit again receives the activation signal.
