Description
Technical field
The utility model relates to a kind of power vehicle battery system refrigerating and heating combined equipment.
Background technology
Nearest more than ten years, under the common promotion of each side's factor, to the application of power vehicle battery more and more widely, also increasingly high to its requirement simultaneously.How ensureing the work that it is safe, stable, will be an important topic of power vehicle battery.How to guarantee that among this stable of battery operated ambient temperature of power vehicle then is one of them very crucial part.Giving the common practice of power vehicle battery cooling at present is air-cooled, water-cooled, and these two kinds of methods can only make battery remain in certain temperature range, also can't make each battery remain on the unified temperature point simultaneously.The power vehicle battery cooling and warming module that success is at present developed provides impetus for the range of application of power vehicle battery, the lifting of technical parameter.
Traditional power vehicle battery temperature module only possesses cooling or heating function, and the thermal module that possesses cooling and heating function simultaneously needs the device by the outside, and portability is not strong, and cost is high.Only can wholely heat up or cooling simultaneously, can not make every battery operated at fixed temperature, make that the working temperature point of each battery is inconsistent when using in groups on a large scale, the local cell problem of aging will appear in use for a long time, thereby influence the life-span of whole battery group.
Summary of the invention
The purpose of the utility model provides a kind of power vehicle battery system refrigerating and heating combined equipment, ensures battery operated optimum state and the trouble free service of power vehicle.
The technical scheme of the utility model is:
A kind of power vehicle battery system refrigerating and heating combined equipment; Comprise two hygral equilibrium parts, two cooling and warming parts, electric core, temperature acquisition parts and control assembly BMS, the affixed two cooling and warming parts of outside symmetry of said electric core, the affixed two hygral equilibrium parts of described two cooling and warming parts outside symmetry; Control assembly BMS connects the cooling and warming parts through lead; One end of temperature acquisition parts connects electric core, and the other end is through lead connection control unit BMS, and described cooling and warming parts are heating and cooling semiconductor chip; Described temperature acquisition parts use the NTC temperature sensor, and described NTC is a negative temperature coefficient.
The characteristic of freezing, heating of the utility model through semiconductor chilling plate solve the battery pack refrigeration, need not be when heating compatibling problem by external device (ED); Saved the space; The convenient transplanting; Adopt the discrete design of gathering, controlling simultaneously, all adjustable to the temperature of every battery, battery all is operated under the unified temperature.
Realized every battery operated under steady temperature, strengthened the useful life of battery pack, reduced the use cost of battery pack, simultaneously for the bigger capacity of exploitation, charge and discharge battery faster the temperature guarantee be provided.

Embodiment
Below in conjunction with accompanying drawing and instance the utility model is done further to describe.
As shown in Figure 1, a kind of power vehicle battery system refrigerating and heating combined equipment comprises hygral equilibrium parts, cooling and warming parts, electric core, temperature acquisition parts and control assembly BMS; The affixed two cooling and warming parts of outside symmetry of said electric core; The affixed two hygral equilibrium parts of described two cooling and warming parts outside symmetry, control assembly BMS connects the cooling and warming parts through lead, and an end of temperature acquisition parts connects electric core; The other end is through lead connection control unit BMS; Described cooling and warming parts are heating and cooling semiconductor chip, and described temperature acquisition parts use the NTC temperature sensor, and described NTC is a negative temperature coefficient.
As shown in Figure 2, the hygral equilibrium parts are made of metal, and effect is the temperature of the non-electric core end of balance cooling and warming parts, and itself and ambient temperature are consistent, and for each parts platform are provided fixedly;
Balance cooling and warming parts are heating and cooling semiconductor chip, and effect is to regulate electric wicking surface temperature;
The temperature acquisition parts use the NTC temperature sensor, and effect is the electric wicking surface temperature of detecting;
Control assembly BMS effect is the temperature of treatment temperature acquisition component information, control cooling and warming parts; Fixed part is made up of double-screw bolt and screw, and effect is the position of fixed temperature equalizing feature, cooling and warming parts and electric core.
For being close together, its heat-conducting silicone grease of contact-making surface interpolation is in twos filled between hygral equilibrium parts, cooling and warming parts, the electric core.Fix with screw between the hygral equilibrium parts.Control assembly is connected with temperature acquisition parts and cooling and warming parts through lead.
Control assembly is learnt the temperature of electric wicking surface through treatment temperature acquisition component information, and contrast inner setting program is judged this electricity core and is operated in excess temperature, low temperature or normal state.Thereby start the controlling mechanism of corresponding balance cooling and warming parts, make through balancing the energising of cooling and warming parts forward, reverse energising, no power that balance cooling and warming parts are operated in refrigeration, heat, off position.Regulate the refrigeration of cooling and warming parts, heating capacity through regulating its size of current.Regulate and control electric wicking surface temperature through the heat transmission between cooling and warming parts and the electric core; Make the non-electric core end temperature of cooling and warming parts and ambient temperature consistent through hygral equilibrium parts and heat transmission between the cooling and warming parts, thereby improve effective operating efficiency of cooling and warming parts.
The utility model lithium ion cooling and warming module can produce with ambient temperature ± 50 ° the temperature difference, and each battery temperature is adjustable separately, also can use with air-cooled, water-cooling system collocation commonly used now.
