1. An electrically powered vehicle comprising:
a chargeable/dischargeable power storage device; a motor configured to generate vehicle driving power when receiving electric power supplied from said power storage device, and to regenerate electric power, which is generated during regenerative braking of the vehicle, to said power storage device; an auxiliary load; a charging control unit that sets a fully charged state of said power storage device so as to have a margin for a fully charged capacity of said power storage device, and that sets a charging power upper limit value permitted in said power storage device, in accordance with an upper limit value of a charge state value of said power storage device, said upper limit value of said charge state value being defined to be associated with said fully charged state; and a traveling control unit that controls charging power for said power storage device within a range defined by said charging power upper limit value, said charging control unit setting said fully charged state to be variable in accordance with a degree of deterioration of said power storage device such that said margin becomes smaller as the degree of deterioration of said power storage device is larger, said traveling control unit switching between first control and second control in accordance with a degree of decrease of said margin when regenerative electric power generated by said motor during regenerative braking of the vehicle exceeds said charging power upper limit value, said first control being control for regenerating, to said power storage device, an excess of said regenerative electric power relative to said charging power upper limit value, said second control being control for consuming the excess of said regenerative electric power using said auxiliary load. |
