The power supply controller controls the supply of electric power from a first power supply source to a predetermined facility having a first power supply destination and a second power supply destination, and also controls the supply of electric power to the predetermined facility from the second power supply source that is powered by a battery installed in a plurality of electric vehicles parked in a parking lot attached to the predetermined facility. The power supply controller prioritizes the first power supply source over the second power supply source when there is an abnormality in the first power supply source.

Power supply controller

There is provided a motor vehicle including a lithium ion capacitor; an electrical load configured to transmit electric power to and from at least the lithium ion capacitor; and a control device. The control device is programmed to control the lithium ion capacitor such as to be charged and discharged according to a discharging excess pattern that provides a higher discharge current value than a charging current value, when a degree of degradation of the lithium ion capacitor reaches or exceeds a predetermined level by charging and discharging the lithium ion capacitor according to a charging excess pattern that provides a higher charging current value than a discharge current value.
