Problems solved by technology

However, for example, when the ambient temperature outside the vehicle is high or when the insulation strength in the vehicle interior is increased by sunlight reaching the interior of the vehicle through the window glass, there are cases where the cooling air blown from the blower is blown before reaching the suction port. heating, and thereby prevents rapid cooling of the condenser

Embodiment Construction

[0026] One embodiment of a cooling apparatus for an electric storage device of an electric vehicle according to the present invention will be described below with reference to the accompanying drawings. In the following description, directions such as front, rear, left, and right correspond to directions of the vehicle, unless otherwise specified. Also, in the drawings, an arrow F indicates a forward direction, an arrow R indicates a backward direction, an arrow L indicates a leftward direction, and an arrow R indicates a rightward direction.

[0027] 1, 2 show a hybrid vehicle (electric vehicle) provided with a cooling device for a condenser of an electric vehicle 1 of the present embodiment. This hybrid vehicle is a so-called parallel type in which an engine 2 and a motor generator 3 (vehicle drive motor) are connected in series, and the drive power of these is transmitted to drive wheels (for example, front wheels Wf) through a transmission 4 . Motor generator 3 is configu...

Abstract

A cooling unit for an electrical storage device (7) in an electrically driven vehicle comprises a drive motor (3) fed from the store through a rectifier and comprising a cooling unit (8) with a fan (9) sending cool air into the cabin interior. An extractor (16) removes cool air from the cabin and leads it to the electrical storage unit and a control unit (30) raises the fan speed in operation and if the electrical storage unit temperature exceeds a predetermined value. An independent claim is also included for a cooling method comprising the above.

Description

technical field [0001] The present invention relates to a cooling apparatus and a cooling method for an electric storage device of an electric vehicle such as a hybrid vehicle and an electric vehicle provided with a vehicle drive motor, and electric energy is passed from an electric storage device such as a battery and a capacitor through an inverter ( inverter) is supplied to the vehicle drive motor. In particular, the present invention relates to a cooling apparatus and cooling method for an electric storage device of an electric vehicle that cools the electric storage device by using cooling air supplied from a cooler to a cabin interior. Background technique [0002] Electric vehicles such as hybrid vehicles and electric vehicles are provided with a high-pressure condenser that supplies electric power to a motor generator during driving and is charged with electric power generated by the electric motor during deceleration. The condenser is normally housed in a power equ...
