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 unit1includes a box10which accommodates devices for controlling electric power supply of the electric vehicle; a reactor receiver 11awhich is provided on a given external surface around the box10and supports a reactor R; a heat sink12connected to the lower end of the reactor receiver 11a, covering the bottom surface of the box10, possessing passages including passage wall inside thereof, and performing heat-exchange with the box10by allowing coolant water to flow within the passage; and a partition 13a, which is laid on at least one side of the box10extending toward the longitudinal direction of the vehicle EV, and is detachably communicated with cables to be connected to the traction motor4disposed below the heat sink12to supply power.
