First Claim
1. A power control unit for an electric vehicle comprising:
- a traction motor which is provided at a front area of said electric vehicle, and whose outputting shaft is directed toward a width direction of said vehicle;
a box which is provided above said tractor motor and which accommodates a device for controlling an electric power supply of said electric vehicle;
a connector case which is detachably provided on one side of the box; and
a plurality of electric cables which are connected to the connector case and are arranged toward a longitudinal direction of said vehicle, wherein a first part of the electric cables is connected to said traction morotr, and wherein a second part of the electric cables passes through the other end side in the width direction of the traction motor, which is a side not having said outputting shaft and is connected to a power supply apparatus disposed below a cabin of said vehicle.

Abstract
A power control unit for electric vehicle which can easily detach the high voltage cables even if the motor room is deformed, for example, by head-on collision and/or rear-end collision of the vehicle, which is difficult to be deformed, which can make small, and which can avoid an influence of heat generated by the reactor is disclosed. The power control unit 1 includes a box 10 which accommodates devices for controlling electric power supply of the electric vehicle; a reactor receiver 11a which is provided on a given external surface around the box 10 and supports a reactor R; a heat sink 12 connected to the lower end of the reactor receiver 11a, covering the bottom surface of the box 10, possessing passages including passage wall inside thereof, and performing heat-exchange with the box 10 by allowing coolant water to flow within the passage; and a partition 13a, which is laid on at least one side of the box 10 extending toward the longitudinal direction of the vehicle EV, and is detachably communicated with cables to be connected to the traction motor 4 disposed below the heat sink 12 to supply power.
