Electrokinetic cell is the key technology of electric motor car, battery temperature is too high or battery cell between temperature contrast increase, will
Shorten the service life of battery.The height and diversity of temperature has double influence to power battery pack：The rising meeting of temperature
The internal resistance of battery is reduced, accelerates internal chemical reaction rate, there are some researches show battery when working for 45 DEG C, cycle-index is reduced
60%；When battery charges under high magnification, temperature rise reaches 5 DEG C halves will the life-span of battery.So pile cooling
There is highly important realistic meaning to whole electric vehicle performance.
Current electrokinetic cell cooling technology can be divided into liquid cooling, phase-change material cooling, heat pipe according to heat transfer medium
Cooling etc..Liquid cooling is exactly by the use of water or other liquid as heat transfer medium.Compared with air-cooled technology, liquid cooling tool
There is good cooling radiating effect, shortcoming is relatively costly, and whole system is more complicated.Generally for guarantee set of cells and liquid
Good insulation between body can be arranged in pipeline between battery module, and maintenance difficulties are higher, and leakage problem is directly affected entirely
The insulating properties of set of cells and safety.
Phase-change material cooling is that energy is discharged or stored using latent heat during material phase transformation.Set of cells operationally can be produced
Raw amount of heat, now by phase transformation absorption heat, a portion heat is pulled away phase-change material, serves thermolysis.
Phase-change material radiating effect generally to be preferred over air radiating, but also have some shortcomings：Phase-change material is directly contacted with battery module
During heat exchange, the effect for cooling down radiating can be then affected in the event of deformation；And because complicated structure increased the weight of system
And cost.
Heat pipe cooling will reach reasonable effect need to coordinate fin and fan, while also to ensure heat pipe and set of cells
Between must have good contact, the otherwise cooling effect of heat pipe will be greatly affected.Electrokinetic cell heat pipe cooling technology mesh
It is front also in the laboratory research stage.
