Problems solved by technology

Including the occasion of such installation, especially the occasion where the high-voltage electrical packaging box is installed close to the compartment, when it is placed in hot weather, it will have a bad effect on the battery-resulting in a reduction in life
In addition, when the battery is used at low temperature and under air, there are also adverse effects accompanying the freezing of the electrolyte-increased internal resistance and reduced output power

Embodiment Construction

[0025] The structure of a high-voltage electrical packaging box according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0026] The high-voltage electrical packaging box structure of this embodiment is suitable for use as a high-voltage storage battery cooling device for automobiles. Moreover, the automobile of this embodiment is a hybrid automobile. In such a hybrid automobile, when the battery of the DC power supply supplies power to the motor, it is converted from direct current to alternating current by means of an inverter, and the output power of the engine or the function of the vehicle When a part of the battery is stored by the motor, the inverter converts the AC into a DC for storage. Moreover, since the DC voltage converted by the inverter is high voltage, a part of it is stepped down by a DC / DC converter. Therefore, the high-voltage battery cooling device is used to cool these batteries, inverters, ...

Abstract

The high-voltage electrical packaging box structure can prevent adverse effects on the performance of high-voltage electrical products regardless of whether the temperature in the compartment is too high or too low. The inside of the box body (70) accommodates high-voltage battery components (5, 7, 8). Sandwich parts (200-203) made of foamed resin are installed in the gap between the box body (70) and the high-voltage battery parts (5, 7, 8). Air can flow through the inside of the box to cool the high voltage electrical products inside.

Description

technical field [0001] The invention relates to a high-voltage electrical packaging box structure containing heat-generating high-voltage electrical (bottle) products, also known as a high-voltage battery box structure (packaging box). Background technique [0002] For example, in electric vehicles and hybrid vehicles, high-voltage electrical products such as batteries and control devices are housed in high-voltage electrical packaging boxes without shielding and arranged in the vehicle. [0003] However, the present applicant thinks that, in order to efficiently install in the vehicle, the above-mentioned high-voltage electrical packaging box should be installed along the back of the rear floor. Including the occasion of such installation, especially the occasion where the high-voltage electrical packaging box is installed close to the compartment, when it is placed in hot weather, it will have a bad effect on the battery-resulting in a reduction in life. In addition, when...
