Problems solved by technology

Since many high-voltage components such as battery cells and inverters are housed inside the battery case and are connected to each other by cables, when the high-voltage equipment is pressed by the fan rotor advancing under the impact load, misplacement occurs. When moving, the cables to which the high voltage is applied are pulled and damaged, which may short-circuit to the ground with the metal parts of the vehicle body

Embodiment Construction

[0048] Below, based on Figure 1 to Figure 12 , to describe the embodiment of the present invention.

[0049] Such as figure 1 As shown, a recessed portion 11a is formed on a bottom plate 11 of a trunk room at the rear of a vehicle body of a hybrid vehicle, and a packaged battery 12 is mounted in the recessed portion 11a. The battery pack 12 includes: a container-shaped synthetic resin case 13 with an open upper surface; a metal cover 14 formed in a plate shape to close the upper surface opening of the case 13; Front holding members 15 and rear holding members 16 made of metal are fixed at their ends to the upper surface of the bottom plate 11 . The housing 13 and the cover 14 are fixed to the front holding member 15 and the rear holding member 16 , and are suspended and supported in the recess 11 a via the front holding member 15 and the rear holding member 16 .

[0050] Such as figure 1 and figure 2 As shown, the middle parts in the vehicle width direction of the front...

Abstract

The present invention provides a vehicle-used power storage device, and an object of the invention is to prevent damage to cables of the power storage device when a vehicle receives a back collision. A package battery (12) mounted at the rear body of the vehicle includes: a battery module (20); a PCU (23) connected with the battery module (20); a front holding component (15) and a rear holding component (16) which clamp and hold the battery module and the PCU (23) from the front and back sides, respectively; and a cooling fan (27) mounted on the back surface of the rear holding component (16) through a bracket (31). The front and back load that the bracket (31) can withstand is smaller than the front and back load that the rear holding component (16) can withstand, so that if a collision load caused by back collision is applied to the cooling fan (27), the bracket (31) is deformed and absorbs the impact, thereby preventing the rear holding component from deformation. Therefore, relative displacement of the battery module and the PCU (23) can be prevented, and the damage to the cables connecting the battery module and the PCU is thereby prevented.

Description

technical field [0001] The present invention relates to a power storage device for a vehicle, which is mounted on the rear of a vehicle body and includes: a battery pack; a high-voltage member connected to the battery pack via a cable; The group and the high-voltage component are held and fixed to the front holding member and the rear holding member of the vehicle body from the front and rear, and the auxiliary equipment is mounted on the rear surface of the rear holding member via a bracket. Background technique [0002] A vehicle electric storage device is known from the following Patent Document 1. Two front and rear frames extending in the front and rear directions of the vehicle body and two beams extending in the vehicle width direction are combined into a frame shape, and a plurality of The battery case of the battery is supported in a state offset to one side in the vehicle width direction, and a cooling fan for cooling the battery is disposed in a space formed on th...
