Abstract
A control apparatus calculates the capacitor maximum power (P) that can be supplied to a capacitor depending on the detected value of the temperature of the capacitor, and calculates the output power (P) of the fuel cell, the real power of the motor (P) that actually powers the drive motor, and the load power (P) that actually powers an electrical load, excluding the drive motor. The control apparatus calculates the motor power limiting value (P), which is the motor power that corresponds to the capacitor maximum power (P), based on the output power (P) of the fuel cell, the load power (P) that powers the electrical load, excluding the drive motor, and the capacitor maximum power (P). The control apparatus output to the output controller a control command that directs the real power of the motor (P) to take the value of the motor power limiting value (P) in the case that the real power of the motor (P) is larger than the motor power limiting value (P). The drivability of a fuel cell vehicle is improved while protecting the capacitor.
