摘要： An on-vehicle power supply device according to the present disclosure includes an electricity storage, a charge circuit, a discharge circuit, an input unit, an output unit and a controller. When the controller decides that an emergency operation condition is satisfied, the controllers causes the charge circuit to stop charging power to the electricity storage, then sets an output instruction voltage that is a target voltage value of an output of the discharge circuit to a first voltage value, the controller further causes the discharge circuit to discharge the power charged in the electricity storage, and, when the power output from the discharge circuit becomes higher than a power threshold, the controller lowers an output instruction voltage from a first voltage value to a second voltage value.

摘要： A vehicle-mounted power source device includes: a power storage unit; a charging unit; a discharging unit; and a control unit which controls operations of the charging unit and the discharging unit in accordance with an activation signal. When the control unit receives the activation signal, the terminal voltage of the power storage unit becomes the first voltage through a charging operation of the charging unit, and when the control unit finishes receiving the activation signal, the discharging unit starts a discharging operation, and the terminal voltage of the power storage unit is reduced to a second voltage lower than the first voltage. The charging unit applies a third voltage lower than the second voltage to the power storage unit between (i) when the terminal voltage of the power storage unit becomes lower than the second voltage or when a predetermined length of time has elapsed since the terminal voltage of the power storage unit became lower than the second voltage and (ii) when the control unit receives the activation signal again.

摘要： A backup power system according to the present disclosure includes a battery, a charging circuit, power storage, a first load, a second load, and a controller that controls the charging circuit. The controller causes an input current at the charging circuit to increase at a first rate of change in response to a start signal. When the controller detects an increase in a charging voltage at the power storage up to a first voltage at which driving of the first load is possible, the controller controls the charging circuit to cause the input current at the charging circuit to increase at a second rate of change lower than the first rate of change. The charging circuit is controlled by the controller to cause the input current to increase at the second rate of change, and the charging voltage at the power storage increases up to a second voltage at which driving of both the first load and the second load is possible.

摘要： An in-vehicle power supply device according to the present disclosure includes an input terminal, a charge-discharge circuit connected to the input terminal, a first output terminal connected to the charge-discharge circuit via a first switch unit and a first cut-off unit, a second output terminal connected to the charge-discharge circuit via a second switch unit and a second cut-off unit, and a controller connected to the input terminal, the first output terminal, and the second output terminal. The controller controls the charge-discharge circuit, the first switch unit, the first cut-off unit, the second switch unit, and the second cut-off unit. When the controller detects that a voltage of the first output terminal becomes lower than the first load threshold voltage, the first cut-off unit changes from a connected state to a cut-off state. After a lapse of a first predetermined period following a time at which the controller detects that the voltage of the first output terminal is lower than the first load threshold voltage, the second switch unit switches from a state of higher-resistance conduction to a state of lower-resistance conduction in which a resistance level is lower than the resistance level in the state of higher-resistance conduction.
