Abstract

Official abstract text for this publication.

An electric vehicle includes a motor drive section that supplies electric power from a main battery to a motor to drive the motor. The motor drive section can include an inverter configured to convert direct current from the main battery into alternating current, and a capacitor configured to stabilize an operation of the inverter. A resistor is configured to discharge electric charge of the capacitor, and discharge operation unit can be configured to manually control the resistor to discharge the electric charge of the capacitor.
