Problems solved by technology

[0004] However, the above-mentioned existing invention cools the battery module and electrical components in parallel by providing the air intake duct on the front side of the vehicle body and the exhaust duct on the rear side of the vehicle body, and therefore is different from making the air intake duct and the exhaust duct on the vehicle body. Correspondingly, the front and rear separate settings have the problem of increasing the size of the power unit in the front and rear directions

no. 1 approach

[0036] First, based on Figure 1 to Figure 8 A first embodiment of the present invention will be described.

[0037] Such as figure 1 As shown, a power supply device for operating a motor / generator of a hybrid vehicle is accommodated by using a tire pan 11 in a trunk 43 at the rear of the vehicle body (refer to figure 2 and image 3 ) to accommodate the spare wheel. Left and right side edges of a container-shaped tire disc 11 depressed downward are connected to left and right rear side members 12 , 12 . The power supply unit includes a container-shaped waterproof case 14 with an open upper surface, a flat plate-shaped cover member 15 that closes the upper surface opening of the waterproof case 14, and a pair of front and rear suspension frames 16, 16 at both ends in the vehicle width direction. The pair of suspension frames 16 and 16 are fixed to the upper surfaces of the left and right rear side members 12 and 12 by bolts 17 . Therefore, the power supply unit is suspend...

[0061] Next, based on Figure 9 A second embodiment of the present invention will be described.

[0062] The duct member 18 of the second embodiment is configured by combining the intake passage portion 41 and the exhaust passage portion 42 as separate members and integrally combining them. In this embodiment, although the number of components is increased compared with the first embodiment, the degree of freedom in designing the shape of the duct member 18 is increased.

Abstract

A vehicular power supply system is provided in which the interior of a waterproof case (14) is partitioned into a first cooling air passage (39) on the lower side and a second cooling air passage (40) on the upper side, a battery module (24) is cooled with cooling air that is introduced from an intake passage part (41) of a duct member (18) and flows through the first cooling air passage (39) on the lower side, and high voltage electrical components (33, 34) are then cooled by guiding the cooling air to the second cooling air passage (40) on the upper side via an intermediate duct (36). After a cooling fan is stopped, air that has been heated by the high voltage electrical components (33, 34), which have a high temperature, is discharged via an exhaust passage part (42) of the duct member (18) without contacting the battery modules (24) on the lower side. Moreover, since the intake passage part (41) and the exhaust passage part (42) are provided integrally in the duct member (18), which is provided at one end of the waterproof case (14), compared with an arrangement in which they are provided separately at opposite ends of the waterproof case (14), the power supply system can be made smaller.

Description

technical field [0001] The present invention relates to a power supply device for a vehicle in which a power unit composed of an accumulator and electric components is arranged inside a case, and the inside of the case is divided into a first cooling air passage and a second cooling air passage , using the cooling air supply device to supply cooling air to the first and second cooling air passages, cooling the accumulator with the cooling air flowing through the first cooling air passage, and cooling the accumulator with the cooling air flowing through the second cooling air passage The cooling air cools the electrical components. Background technique [0002] In the following Patent Document 1, an invention is known in which a battery module is arranged in the lower part of a power supply unit arranged under the floor behind the seat of a motor vehicle, and a DC / DC converter is arranged in parallel in the vehicle width direction in the upper part. With the inverter for dri...
