The development of electric automobile be unable to do without electrokinetic cell system, electrokinetic cell system supports car load to travel for electric motor car provides electric energy, electrokinetic cell is as a chemical assembly, there is its this attribute of intrinsic internal resistance, no matter electrokinetic cell is charged state or discharge condition, as long as electric current is arranged by internal resistance, the capital internal resistance of cell produces heat, cause battery temperature to raise, the best serviceability temperature scope of battery is about 25 ℃, excess Temperature can cause inside battery to damage, and we just need to cool off electrokinetic cell system like this, make it reach an optimum Working.Whole electrokinetic cell system is that the battery core body by One's name is legion is in series, magnitude of voltage between the core body is basic identical, all core bodys keep synchronous discharging current and same pressure drop rate in discharge process like this, and so just need to guarantee that all core bodys have identical temperature when discharging, in case otherwise electrokinetic cell core body temperature is inconsistent, the battery that temperature is low in the discharge process is so emitted more electric weight with the battery higher than temperature, the phenomenon of putting easily occurred, existing cooling system is difficult to the uniformity that guarantees that electrokinetic cell cools off in discharge process.Existing air cooling system, the method that adopts is to import cooling air in the electrokinetic cell course of work, make it to carry out heat exchange with electrokinetic cell, thereby finish the cooling to electrokinetic cell, but when carrying out air-cooled cooling, the problem that occurs is always very fast near the battery modules cooling at cooling air outlet place, and it is slower away from the electrokinetic cell cooling at air outlet place, so just caused the electrokinetic cell cooling the time each battery modules and core body temperature can't balance, the electric current that battery core body faster of lowering the temperature is first emitted is relatively large, the decrease speed of voltage is very fast, be easy to cause the mistake of electrokinetic cell part to put phenomenon, serious meeting destroys electrokinetic cell performance and cycle life.Also have a kind of liquid cooling mode to solve electrokinetic cell and cool off uniform problem, the VOLT of AM General for example, but problem is a cover liquid cooling system, the liquid volume of itself is very large, increase the very large weight load of car load, and the liquid cooling pipeline is in a single day damaged, and interference is caused in the inside that easily flows into battery system.
The utility model content
The technical problem that the utility model solves is to provide a kind of power battery cooling system, can guarantee discharge, can guarantee again the evenly cooling system of cooling of battery.
In order to overcome the above problems, the utility model provides a kind of power battery cooling system, comprise electrokinetic cell pallet, A electrokinetic cell inclusion, B electrokinetic cell inclusion, air pipe, wind direction flow controlling mechanism, 2 wind direction controlling organizations and air-conditioning system, on the electrokinetic cell pallet installation screw is arranged, be connected with the car load bottom by construction bolt; A electrokinetic cell inclusion and B electrokinetic cell inclusion are separately fixed on the electrokinetic cell pallet, are connected with entire car controller respectively, realize separate work; The air pipe air inlet connects air-conditioning system, share an air pipe at A electrokinetic cell inclusion and B electrokinetic cell inclusion junction, be provided with wind direction flow controlling mechanism in the middle of sharing air pipe, two ends respectively are provided with a wind direction controlling organization, and described wind direction flow controlling mechanism, wind direction controlling organization baffler are rotatable; The air pipe other end connects air outlet in the car, and cooled gas is discharged.
Further, as preferably, air pipe is arranged in electrokinetic cell inclusion top, is installed in the centre gangway of bottom of car.
The utility model is by being divided into electrokinetic cell two parts, both work that hocket, another part is not worked during part work, then working portion is not cooled off, the battery infringement that has caused with regard to having avoided battery discharge in the cooling procedure like this, and native system makes electrokinetic cell reach the effect of even cooling in cooling procedure also by the conversion of wind direction.

Embodiment
Referring to figure embodiment of the present utility model is described.
For above-mentioned purpose, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, 2, a kind of power battery cooling system, comprise electrokinetic cell pallet 1, A electrokinetic cell inclusion 2, B electrokinetic cell inclusion 3, air pipe 4,6,2 wind direction controlling organizations 7 of wind direction flow controlling mechanism, 8 and air-conditioning system, on the electrokinetic cell pallet 1 installation screw is arranged, be connected with the car load bottom by construction bolt; A electrokinetic cell inclusion 2 and B electrokinetic cell inclusion 3 are separately fixed on the electrokinetic cell pallet 1, are connected with entire car controller respectively, realize separate work; Air pipe 4 air inlets 10 connect air-conditioning system, share an air pipe 4 at A electrokinetic cell inclusion 2 and B electrokinetic cell inclusion 3 junctions, be provided with wind direction flow controlling mechanism 6 in the middle of sharing air pipe 4, two ends respectively are provided with a wind direction controlling organization 7,8, and described wind direction flow controlling mechanism 6, wind direction controlling organization 7,8 bafflers are rotatable; Air pipe 4 other ends connect air outlet 9 in the car, and cooled gas is discharged.
Embodiment 1
As shown in Figure 2, in the motor vehicle driving process, A electrokinetic cell inclusion 2 and B electrokinetic cell inclusion 3 drive car load to car load output electric energy respectively and travel, this moment is because A electrokinetic cell inclusion 2 internal temperatures reach limit value, then A electrokinetic cell inclusion 2 quits work, system is automatically converted to be powered by B electrokinetic cell inclusion 3 and drives car load and normally travel, cooling system cools off A electrokinetic cell inclusion 2, introducing cold wind from air-conditioning system is entered by air inlet 10, run into wind direction flow controlling mechanism 6 and enter the airduct place, again be guided to the airduct place by wind direction controlling organization 7, import thus A electrokinetic cell inclusion 2 inside, flowed out by the place, air port through circulation, run into again the wind direction guiding device, enter outlet, discharged by the airduct place.
Embodiment 2:
As shown in Figure 3, in order to keep the cooling uniformity of electrokinetic cell, whole wind direction system flow is carried out contrary circulation to change, makes the battery system temperature reach balance.So behind the cooling certain hour, air-conditioning system is introduced cold wind and is entered by air inlet 10, run into wind direction flow controlling mechanism 6 and enter the airduct place, and wind direction flow controlling mechanism 6 rotations this moment make its change of the wind direction, are guided to the airduct place by wind direction controlling organization 8, import thus A electrokinetic cell inclusion 2 inside, flowed out by the place, air port through circulation, run into again wind direction guiding device 7, discharged by the airduct place.Because A electrokinetic cell inclusion 2 be off position, but shutdown system after cold wind circulates make between cold wind and electrokinetic cell, each core body of electrokinetic cell and carry out more fully heat exchange, reach more balanced effect with this.
Such as Fig. 4, be the end view of whole system, air pipe 4 is arranged in electrokinetic cell inclusion 2,3 tops, is installed in the centre gangway of bottom of car, can maximum reasonable utilize the space.
