Abstract
An electrically-driven vehicle includes a power storage device that stores power to be supplied to a motor, and a controller that controls output of the power storage device. The controller estimates a SOC of the power storage device. The controller detects output power of the power storage device and calculates an output power upper limit value of the power storage device by using the SOC when a voltage of the power storage device reaches a lower limit voltage during discharge of the power storage device. The controller stops the electrically-driven vehicle in the case where the detected output power is lower than the output power upper limit value.
