Power supply controller

A power supply system, comprising:

• a power storage device disposed in a vehicle;
• an outside-of-vehicle power system disposed outside of the vehicle and having a breaker that (a) supplies electric power from a commercial power system to an internal load of the outside-of-vehicle power system and (b) interrupts a power supply from the commercial power system to the internal load when the outside-of-vehicle system is in operation;
• and
• a power supply controller connected with the power storage device and with the outside-of-vehicle power system and configured to perform a charge control that charges the power storage device disposed in the vehicle with electric power supplied from the outside-of-vehicle power system, the power supply controller configured to include:
• a power amount controller controlling a supply power amount of the charge control;
• and
• a determiner determining whether a management device is available to control a power supply to the internal load of the outside-of-vehicle power system;
• and
• a charge control memory unit;
• wherein
• the power amount controller performs a first control that determines the supply power amount according to an instruction value received from the management device when the determiner determines that the management device is available, the charge control memory unit storing the instruction value received from the management device, and
• the power amount controller performs a second control that determines the supply power amount according to information about a past power supply from the outside-of-vehicle power system when the determiner determines that the management device is unavailable by controlling the supply power amount of the charge control so that an actual power value supplied to the outside-of-vehicle power system does not exceed the instruction value previously stored in the charge control memory.

A power supply controller connected with a power storage device disposed in a vehicle and with an outside-of-vehicle power system disposed outside of the vehicle, the outside-of-vehicle power system having a breaker that (a) supplies electric power from a commercial power system to an internal load of the outside-of-vehicle power system and (b) interrupts a power supply from the commercial power system to the internal load when the system is in operation, the power supply controller for performing a charge control that charges the power storage device disposed in the vehicle with electric power supplied from the outside-of-vehicle power system, the power supply controller comprising:

• a power amount controller controlling a supply power amount of the charge control;
• and
• a determiner determining whether a management device is available to control a power supply to the internal load of the outside-of-vehicle power system;
• and
• a charge control memory unit that stores a power restriction value of the outside-of-vehicle power system;
• wherein
• the power amount controller performs a first control that determines the supply power amount according to an instruction value received from the management device when the determiner determines that the management device is available, and
• the power amount controller performs a second control that determines the supply power amount according to information about a past power supply from the outside-of-vehicle power system when the determiner determines that the management device is unavailable by controlling the supply power amount of the charge control so that an actual power value supplied to the outside-of-vehicle power system does not exceed the power restriction value stored in the charge control memory.
