Abstract

The utility model provides a lithium battery pack case capable of preventing a lithium battery from being overheated. The lithium battery pack case comprises a case body, wherein an air inlet and an air outlet are formed on the side wall of the case body; a waterproof gas-permeable membrane is arranged on the inner side of each of the air inlet and the air outlet; and the periphery of each of the waterproof gas-permeable membranes is fixed on the inner side of the case body. The waterproof gas-permeable membrane is adhered on the inner side of each of the air inlet and the air outlet of the case body for isolating water molecules in the air, so that relatively dry air without moisture can enter the case for cooling the lithium battery, and therefore, the lithium battery can be prevented from generating an overheating phenomenon in a working process, the performance characteristics of the lithium battery are increased and the service life of the lithium battery is prolonged. Meanwhile, the enclosure of the lithium battery can be prevented from being corroded for a long time by moisture in the air during a cooling process, so that the lithium battery leakage can be avoided.

Description

The overheated lithium battery pack box body of a kind of anti-lithium battery
Technical field
The utility model relates to technical field of lithium batteries, is specifically related to the overheated lithium battery pack box body of a kind of anti-lithium battery.
Background technology
, noiselessness little due to the lithium battery environmental pollution, energy advantages of higher now are used as the power source of new-energy automobile, and its groundwork principle is to provide electric energy by lithium battery to motor, the drive motor running, thus propelling vehicle advances.That lithium battery by some gets up to form high-power, jumbo lithium battery group by series and parallel as the power source of electric automobile.
In the process of charging and discharging lithium battery, assembly on battery itself and large current path can produce heat, can cause the interior temperature of battery pack to continue to rise, meeting reduces serviceability and the useful life of lithium battery after temperature is over the maximum temperature of lithium battery normal operation.Be 60 degrees centigrade as ferric phosphate lithium cell normal operation maximum temperature, surpass 60 degrees centigrade and will greatly reduce battery in useful life.
So in order to protect the serviceability of lithium battery; the lithium battery group is carried out high-temperature control works under excessive temperature to prevent lithium battery; need to lower the temperature to lithium battery; at present comparatively economical and reliably mode be to carry out air-cooledly to ventilating in lithium battery pack box body, air-cooledly divide again in casing and the direct convection current of casing outer air is lowered the temperature to lithium battery in lithium battery pack box body with using in vehicle cooling air-conditioning.But owing to containing certain moisture in air, moisture can enter battery pack inside with cross-ventilation, when moisture reaches a certain amount of, because the ionization meeting of electrode produces corrosion to li battery shell, finally can cause the li battery shell corrosion failure to make the lithium battery generation phenomenon of leakage.
The utility model content
The purpose of this utility model just is to provide the overheated lithium battery pack box body of a kind of anti-lithium battery, and the protection lithium battery avoids being subjected to moisture to corrode, and improves its serviceability.
In order to reach above-mentioned effect, the utility model provides a kind of anti-lithium battery overheated lithium battery pack box body, comprise casing, described wall box is provided with air inlet and air outlet, the inboard of described air inlet and air outlet is equipped with waterproof ventilated membrane, and the surrounding of described waterproof ventilated membrane is fixed on the inboard of described casing.
In order to increase ventilation quantity, described waterproof ventilated membrane is folded into wavy.
In order automatically to control ventilation, be provided with temperature sensor in described casing, the output of described temperature sensor is electrically connected to the lithium battery group manager, and the output of described lithium battery group manager is electrically connected to ventilation equipment.
Described ventilation equipment are fan or the vehicle air conditioner of being located at casing air inlet and air outlet place.
The utility model is inboard by the fixing waterproof ventilated membrane of the modes such as stickup at the air inlet of casing and air outlet, air-conditioning system by fan or vehicle self-carrying is when lowering the temperature in lithium battery group case, extraneous convection current air is first isolated airborne hydrone by waterproof ventilated membrane, allowing the air of the relatively dry of not being with moisture enter in casing lowers the temperature to lithium battery, thereby prevent that lithium battery from producing superheating phenomenon because of the course of work, increase serviceability and the useful life of lithium battery.Simultaneously also avoided for a long time the shell of lithium battery being corroded at the moisture of temperature-fall period Air, and caused lithium battery generation leakage.Waterproof ventilated membrane is folded into wavy, increases the contact area of air and waterproof ventilated membrane, thereby the cross-ventilation amount is increased, increase ventilation quantity, the cooling-down effect of raising to lithium battery.
The utility model is further established a temperature sensor at box house, the temperature of lithium battery in casing detected, and when temperature reaches 30 ℃, can be aeration-cooling to carrying out in casing by lithium battery manager drive fan or air-conditioning system.Reach the purpose of automatic control, and reduce energy consumption.
