Description
Technical field
The utility model relates to automobile technical field, refers to particularly it is a kind of cooling system of batteries of electric automobile group.
Background technology
Electric automobile refers to travel with power wheel take vehicle power as power, meets the vehicle of road traffic, safety regulations requirements.Because it is less to the relative orthodox car of environmental impact, its prospect is extensively had an optimistic view of.Along with the fast development of electric automobile, battery pack is as one of kernel component, and its serviceability more and more receives publicity.Temperature is one of principal element that affects battery performance, because the limitation of battery material itself, when battery pack was at high temperature moved, battery life can shorten, and was too high such as battery pack temperature, also can bring potential safety hazard.Therefore, need a kind of heat abstractor that battery pack is worked under preference temperature of design just to seem is of practical significance very much.
The utility model content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, and a kind of cooling system of the batteries of electric automobile group when battery pack is at high temperature moved is provided.
The technical solution of the utility model is: a kind of cooling system of batteries of electric automobile group, it comprises the heat abstractor that is installed on the Battery case, the power control system that is installed in Battery case inside and system for detecting temperature, system for detecting temperature is evenly arranged on the battery surface of Battery case inside, and power control system is arranged between system for detecting temperature and the heat abstractor.
Described heat abstractor is the cooling piece that connects by semiconductor and the semiconductor heat dissipation device that heats sheet, and described cooling piece is installed in Battery case inside, heats sheet and is installed in the Battery case outside.
The described sheet end that heats is provided with radiator fan, and radiator fan can be accelerated circulation of air, improves radiating efficiency.
Operation principle of the present utility model is: when battery pack is at high temperature moved, when the temperature that system for detecting temperature collects is higher than preset value, power control system control semiconductor heat dissipation device is opened, and the cooling piece of semiconductor heat dissipation device can be opened the processing of lowering the temperature.Simultaneously, heat sheet at the external generation heat of Battery case, distribute by radiator fan.When the temperature that collects when system for detecting temperature was lower than preset value, power control system control semiconductor heat dissipation device was closed, and semiconductor heat dissipation device quits work, and worked under suitable temperature to guarantee battery pack.
The utlity model has simple in structure, sealing reliability is high, volume is little, use and keep in repair the advantage safe, easy to operate, that integration is high, can carry out efficiently radiates heat to the batteries of electric automobile group, extending battery life prevents the potential safety hazard that causes because battery pack temperature is too high.

Specific implementation method
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not consist of restriction to the utility model.
The cooling system of a kind of batteries of electric automobile group as shown in Figure 1 and Figure 2, it comprises the heat abstractor 1 that is installed on the Battery case 2, the power control system 3 that is installed in Battery case 2 inside and system for detecting temperature 4, system for detecting temperature 4 is evenly arranged on the battery surface of Battery case 2 inside, power control system 3 is arranged between system for detecting temperature 4 and the heat abstractor 1, and power control system 3, system for detecting temperature 4 are connected in series with heat abstractor 1.Heat abstractor 1 is the cooling piece 1.1 that connects by semiconductor and the semiconductor heat dissipation device that heats sheet 1.2, described cooling piece 1.1 is installed in Battery case 2 inside, heat sheet 1.2 and be installed in Battery case 2 outsides, be provided with radiator fan 1.3 heating sheet 1.2 ends, radiator fan 1.3 can be accelerated circulation of air, improves radiating efficiency.
The type of the adaptable battery pack of the utility model can be in lithium ion battery, lead-acid battery or the fuel cell a kind of, the battery pack in the present embodiment is lithium ion battery.
The type of the adaptable electric motor car of the utility model is a kind of in pure electric automobile, mixed power electric car, external charge formula hybrid vehicle or the fuel cell electric vehicle, and electric motor car is pure electric automobile in the present embodiment.
The operation principle of present embodiment is: when battery pack is at high temperature moved, when the temperature that system for detecting temperature 4 collects is higher than preset value, power control system 3 control semiconductor heat dissipation devices 1 are opened, and the cooling piece 1.1 of semiconductor heat dissipation device 1 can be opened the processing of lowering the temperature.Simultaneously, heat sheet 1.2 at the external generation heat of Battery case, distribute by radiator fan 1.3.When the temperature that collects when system for detecting temperature 4 was lower than preset value, power control system 3 control semiconductor heat dissipation devices 1 were closed, and semiconductor heat dissipation device 1 quits work, and works under suitable temperature to guarantee battery pack.
As shown in Figure 3, the Battery case 2 that installs heat abstractor is put into high-temperature cabinet and is tested: 1, do not open heat abstractor, Battery case 4 is heated, when temperature reaches 55 °, make high-temperature cabinet keep temperature constant state, the temperature data in the record high-temperature cabinet is also drawn temperature figure line A; 2, open heat abstractor, Battery case 4 is heated, when temperature reaches 55 °, make high-temperature cabinet keep temperature constant state, the temperature data in the record high-temperature cabinet is also drawn temperature figure line B.The temperature curve A that opens the temperature curve B of heat abstractor and do not open heat abstractor is compared and can find out, after opening heat abstractor, system temperature reduces by 6 degree, illustrates that this device has good radiating effect, can effectively reduce the operating ambient temperature of battery system.
In addition, the utility model can be according to the Battery case inner space, and the effect of required heat radiation selects single or multiple heat abstractors to be applied in the Battery case 2.
