POWER SUPPLY BOX STRUCTURE AND POWER SUPPLY BOX ASSEMBLING METHOD FOR ELECTRIC VEHICLE

摘要

PROBLEM TO BE SOLVED: To improve the workability to assembly a DC-DC converter that supplies electric power to a variety of electric devices mounted on a vehicle by reducing the voltage of a direct current power supply of the battery to be mounted on the vehicle and arranged at the bottom of a power supply box. ;SOLUTION: The power of a battery mounted on a vehicle is supplied to a junction box 17 through a power connector 49, being distributed to a motor driving inverter 13 and a DC-DC converter 15 from the junction box 17. The motor driving inverter 13 drives a motor for moving the vehicle under the command from a motor controller 19 by converting direct current into alternating current, and the DC-DC converter 15 reduces the direct current voltage of the battery, supplying electric power to a variety of electric equipment mounted on the vehicle. The DC-DC converter 15 is fixed on a fixing plate 23, and can be dismounted alone and is connected to the junction box 17 through power terminal composed of a female connector 39 and a male connector 41.;COPYRIGHT: (C)1997,JPO
