Abstract
A power supply device is mountable to a vehicle and includes: a high-voltage battery; a low-voltage battery of which an output voltage is lower than that of the high-voltage battery, and which can be charged by output power from the high-voltage battery; and a control unit configured to perform charging/discharging control for the high-voltage battery and the low-voltage battery. The control unit performs feeding control for causing the high-voltage battery to supply power to a predetermined on-vehicle device while consumed power is higher than a predetermined value in a state in which a main switch of the vehicle is not on.
Claims7
A power supply device mountable to a vehicle, the power supply device comprising:
- a high-voltage battery;
- a low-voltage battery of which an output voltage is lower than that of the high-voltage battery, and which can be charged by output power from the high-voltage battery;
- a detection unit configured to detect an occupant;
- and
- a control unit configured to:
- perform charging/discharging control for the high-voltage battery and the low-voltage battery;
- and
- perform feeding control for causing the high-voltage battery to supply power to a predetermined on-vehicle device when a condition including at least that the occupant is detected is satisfied in a state in which a main switch of the vehicle is not on.
A non-transitory computer readable medium that stores computer executable program instructions by a computer of a power supply device mountable to a vehicle,
- the power supply device being provided with a high-voltage battery, and a low-voltage battery of which an output voltage is lower than that of the high-voltage battery, and which can be charged by output power from the high-voltage battery,
- the program instructions causing the computer to execute:
- a detection step of detecting an occupant;
- and
- a control step of:
- performing charging/discharging control for the high-voltage battery and the low-voltage battery;
- and
- performing feeding control for causing the high-voltage battery to supply power to a predetermined on-vehicle device when a condition including at least that the occupant is detected is satisfied in a state in which a main switch of the vehicle is not on.
A method executed by power supply device mountable to a vehicle,
- the power supply device being provided with a high-voltage battery, and a low-voltage battery of which an output voltage is lower than that of the high-voltage battery, and which can be charged by output power from the high-voltage battery,
- the method comprising:
- a detection step of detecting an occupant;
- and
- a control step of:
- performing charging/discharging control for the high-voltage battery and the low-voltage battery;
- and
- performing feeding control for causing the high-voltage battery to supply power to a predetermined on-vehicle device when a condition including at least that the occupant is detected is satisfied in a state in which a main switch of the vehicle is not on.
