Abstract
The utility model discloses a temperature control device of a lithium battery pack, and belongs to the technical field of lithium batteries. The temperature control device comprises the lithium battery pack consisting of lithium batteries, and is characterized in that electrothermal films with foldable performance are arranged between the lithium batteries. The electrothermal films with foldable performance are arranged between the lithium batteries of the traditional lithium battery pack, and normal working temperature of the lithium batteries is ensured, so that the lithium batteries can be normally used in low-temperature and severe cold regions; and therefore, the application range of the lithium batteries is widened, the safety performance of the lithium batteries is improved, and simultaneously the service life of the lithium battery pack is prolonged; and the PTC electrothermal films are adopted as heating material, so that the temperature control device has the advantages of being high in heating speed and saving the energy. One electrothermal film is adopted for heating a plurality of lithium batteries, so that uniformed heating of each lithium battery is ensured, and simultaneously the using amount of control switches is greatly reduced and the safety performance of the temperature control device is ensured through a single heating film compared with a plurality of heating films.
Description
Technical field
The utility model belongs to technical field of lithium batteries, particularly relates to a kind of attemperating unit of lithium battery group.
Background technology
At present, high speed development along with society, the popularity rate of electric bicycle is more and more higher, existing electric bicycle adopts the lithium battery group as storage battery mostly, find by long-term use link, in the area of low temperature and severe cold, particularly when temperature is reduced to 0 ℃, lithium cell charging is merely able to reach the capacity of 70%-75%, discharge less than 90%, when temperature is lower than below 0 ℃, by lithium battery group power supply can electric motor car can occur then that battery can't charge and discharge or charging and discharge capacity extremely low, influence vehicle and can't normally start or shorten the vehicle mileage of continuing a journey.Use for a long time at low temperatures, cause battery charging and discharging insufficient, make internal short-circuit of battery easily, fire hazardous and some are to the unsafe problem of passengers inside the car.Therefore, a kind of lithium battery group attemperating unit with function of temperature control of design seems particularly important.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, by attemperating unit is set between lithium battery, thereby proposes a kind of attemperating unit with lithium battery group of function of temperature control.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of attemperating unit of lithium battery group comprises the lithium battery group of being made up of lithium battery; Between described lithium battery, be provided with Electric radiant Heating Film with collapsible performance.
As preferably, the utility model has also adopted following technical scheme:
Described Electric radiant Heating Film is the PTC Electric radiant Heating Film.
Described Electric radiant Heating Film is the carbon fiber heating film.
Advantage and the good effect that the utlity model has are:
One, the utility model is by being provided with Electric radiant Heating Film between the lithium battery of traditional lithium battery group, when temperature is crossed when low, guaranteed the normal working temperature of lithium battery effectively, make lithium battery can use normally at low temperature and severe cold area, therefore, widen the range of application of lithium battery, improved the security performance of lithium battery group, prolonged the useful life of lithium battery group simultaneously;
Two, because the utility model has adopted the PTC Electric radiant Heating Film as heating material, under low temperature environment, the initial heating power of PTC Electric radiant Heating Film is bigger, make that the working temperature of lithium battery is promoted at short notice fast, along with improving constantly of lithium battery working temperature, therefore the PTC Electric radiant Heating Film reduces electric current and heating power thereupon gradually, has that firing rate is fast, the advantage of energy savings;
Three, because the Electric radiant Heating Film that the utility model adopts has collapsible performance, therefore one group of lithium battery group only needs an Electric radiant Heating Film can realize the polylith lithium battery is heated simultaneously, has guaranteed the uniformity of every lithium battery heating; Single heating film is compared with a plurality of heating films simultaneously, has also greatly reduced the use amount of control switch, has guaranteed the security performance of attemperating unit.
Description of drawings
Fig. 1 is the first specific embodiment structural representation of the present utility model;
Fig. 2 is the second specific embodiment structural representation of the present utility model.
Wherein: 1, lithium battery; 2, Electric radiant Heating Film.
Embodiment
For further understanding utility model content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, Fig. 2, a kind of attemperating unit of lithium battery group comprises the lithium battery group of being made up of lithium battery 1; Between lithium battery 1, be provided with Electric radiant Heating Film 2 with collapsible performance; Wherein: Electric radiant Heating Film 2 not only has heating function, and has collapsible performance, in use promptly, Electric radiant Heating Film 2 can be wrapped in lithium battery 1 outer wall with arbitrary shape after folding, and such as shown in Fig. 1: every lithium battery 1 all has three faces to be wrapped; Shown in Fig. 2: per two lithium batteries are formed a lithium battery group, by folding Electric radiant Heating Film 2, make Electric radiant Heating Film 2 three bread of each lithium battery group can be wrapped up in then.In this specific embodiment, Electric radiant Heating Film 2 is preferably the PTC Electric radiant Heating Film; Do not select METAL HEATING PROCESS film, carbon fiber heating film, fluorine-resin complex electrocaloric film and some polymer composite Electric radiant Heating Film for use but do not get rid of with above-mentioned characteristic yet.
The PTC Electric radiant Heating Film is the folding heating material of a kind of softness, therefore under low temperature environment, the resistance value of carbon dust conductor is less in the PTC Electric radiant Heating Film, this moment, the initial heating power of PTC Electric radiant Heating Film was bigger, made that the working temperature of lithium battery is promoted at short notice fast, along with improving constantly of lithium battery working temperature, the resistance value of carbon dust conductor constantly increases in the PTC Electric radiant Heating Film, at this moment, the heating power of PTC Electric radiant Heating Film constantly reduces, and finally reaches stable state.
More than a kind of embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
