Description

Battery pack box body with dehumidification function

Technical Field

The utility model relates to a technical field of battery package dehumidification scheme, specific battery package box with dehumidification function that says so, in particular to its mechanical connection structure.

Background

Electric-powered new energy vehicles have been popular in the market after years of development. However, with the increasing of the holding capacity of the electric vehicle, the faults caused by short circuit of the power battery pack of the electric vehicle and failure of BMS hardware are much higher than those of the traditional vehicle in reality. One of the causes of these failures is high air humidity. The working environment of the conventional power battery pack is severe, and the shell of the battery pack is sealed, so that when the battery contains a small amount of moisture, the humidity of the air in the battery pack is high at high temperature, and in addition, the water vapor in the air outside the battery pack can possibly enter the battery pack.

Disclosure of Invention

An object of the utility model is to provide a battery package box with dehumidification function, to the problem that the steam easily gathers and is difficult for the effluvium in the electronic passenger car power battery package of present new forms of energy, design out a novel battery package casing scheme, it has original function not subtract, implement simple structure, fall wet effectual, convenient to use, advantage such as the cost is extremely low. Overcomes the defects in the prior art.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a battery package box with dehumidification function, including battery package box, the internal main room that forms of battery package box, the outside formation dehumidification room of battery package box one side, form the physics between dehumidification room and the main room and keep apart the wall, battery package box opposite side is equipped with 2 at least breather valves, above-mentioned physics isolation wall department also is equipped with 2 at least breather valves, dehumidification room one side is equipped with the air exhauster, the wind channel of air exhauster and the indoor intercommunication of dehumidification room, be equipped with inside humidity transducer in the battery package box, battery package box outer wall is equipped with outside humidity transducer, still be equipped with temperature sensor in the battery package box.

The utility model discloses a battery package box with dehumidification function, beneficial effect: 1. the box body with the dehumidification function solves the problem that the air humidity of the existing power battery pack is too high to be processed in time; 2. the shell of the battery pack in the scheme of the application is very different from the shells of various items in the existing market, and the adjustment of the prior art is very easy; 3. the number of the breather valves is increased by adopting the multi-breather valve, and the dehumidification efficiency is higher; 4. the number of the exhaust fans can be increased as long as one exhaust fan is used, and the exhaust fans are not limited; 5. the added devices have low cost, are conventional mass production devices, and can effectively ensure the quality consistency and controllability; 6. the scheme is simple to use and operate, and the change amount of the control system is small.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The invention will be further described with reference to the accompanying drawings.

The utility model discloses a first embodiment discloses a battery package box with dehumidification function, it is different from prior art and lies in: including battery package box 1, form main room 2 in the battery package box 1, the outside of battery package box 1 one side forms dehumidification room 3, form physics between dehumidification room 3 and the main room 2 and keep apart wall 4, battery package box 1 opposite side is equipped with 2 at least

breather valves

5, 4 departments of above-mentioned physics isolation wall also are equipped with 2 at least

breather valves

5, 3 one side in dehumidification room is equipped with air exhauster 6, the wind channel of air exhauster 6 and the indoor intercommunication of dehumidification room 3, be equipped with inside humidity transducer 7 in the battery package box 1, battery package box 1 outer wall is equipped with outside humidity transducer 8, still be equipped with temperature sensor 9 in the battery package box 1.

The working principle is as follows:

1) the whole battery pack box body is divided into two parts, a battery and other parts are placed in the main chamber, and the ear chamber beside the battery pack box body is a dehumidifying chamber.

2) The distribution positions of the breather valves are important, the breather valves are divided into two groups in equal parts, and the two groups of breather valves are necessarily distributed on the two sides of the box body in an axisymmetric way. This may allow for a more uniform gas flow rate through the battery can casing.

3) A humidity sensor is disposed within the battery pack housing and a humidity sensor is disposed outside the battery pack at an attachment location adjacent the suction fan.

4) Any group of the suction valves and the air draft fans are installed in the side wall of the dehumidifying chamber.

5) The dehumidification chamber is physically isolated from the main chamber, and the waterproof requirement between the two chambers is more than IP 67. The dehumidification chamber is relatively closed to form an air duct or air cavity. The size of the dehumidifying chamber volume is not particularly required.

6) The exhaust fan needs to select the exhaust fan with large air suction quantity and good waterproof performance.

7) The humidity sensor in the box body and the humidity sensor outside the box body can monitor the humidity inside and outside the main chamber at regular time.

8) If main indoor humidity is greater than outdoor humidity, the air exhauster starts, changes the main indoor air of battery package through the breather valve by force, reduces main indoor air humidity.

9) If the temperature in the battery chamber is much higher than that in the outdoor, the exhaust fan is started in due time to reduce the humidity of the air in the main chamber.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the present invention be limited to the specific embodiments thereof. For those skilled in the art of the present invention, for example, the object to be fixed is a circular object that is not an energy accumulator, or the structures of the lower support and the upper support of the energy accumulator are different, but the fixing mechanism is the same, and so on. Without departing from the concept of the present invention, a plurality of simple deductions or replacements can be made, all of which should be considered as belonging to the protection scope of the present invention.
