摘要： A charging cord box has a first opening facing a cord outlet lid and a second opening at a substantially right angle to the first opening. A charging cord is passed through the first opening and the second opening. In storing the charging cord in the box, the charging cord can be lowered spontaneously by its own weight. Further, in drawing the charging cord from the box, a base portion of the charging cord is merely bent and no undue external force is applied to the charging cord. Accordingly, damage to the charging cord can be suppressed.

摘要： A power feed system for feeding power to an electric vehicle includes a motor driving circuit provided with a smoothing capacitor. The motor driving circuit is capable of preventing the smoothing capacitor from being discharged and has a comparatively short main current supply line to reduce unnecessary power loss. The motor driving circuit converts dc supply power into ac supply power to feed the ac supply power to a motor. The motor driving circuit includes the smoothing capacitor and a plurality of semiconductor switching devices, which are built in the motor. An electromagnetic relay is placed within a case housing the motor driving circuit and the electromagnetic relay is controlled to supply a main current to the motor driving circuit and to interrupt the supply of the main current to the motor driving circuit.

摘要： To provide an electric vehicle in which a low voltage power, obtained by conversion from a high voltage power of a main battery by a DC--DC convertor, is supplied to an operation control unit and electric equipment loads such as a lamp and is also used to charge a low voltage secondary battery, in which the main battery and the low voltage secondary battery are prevented from being over-discharged even when a main switch is left in the on-state. A low voltage power VR outputted from a DC--DC convertor is supplied to an exciting winding of a relay and is also supplied to a low voltage secondary battery through a diode. The low voltage power VR is supplied to low voltage loads through a contact of the relay. The DC--DC convertor is so constructed that the output of the low voltage power therefrom is stopped when the output voltage of the DC--DC convertor is reduced to a value less than a specified range due to the reduction in the battery capacity of the main battery. In the case where the battery capacity of the main battery is reduced when the main switch is left in the on-state, the output of the DC--DC convertor is stopped, and the contact of the relay is opened for preventing over-discharge of the low voltage secondary battery.
