Art field.
Background technology
In recent years, lithium-ion-power cell because of its energy density height, small volume, longer cycle life the features such as be increasingly becoming
The main flow power supply of electric automobile.In electric automobile, typically by multiple single lithium batteries serial or parallel connection in different forms
One cell apparatus of composition are fitted together, with voltage or capacity needed for providing.Due to battery in charge and discharge process its own
Temperature can be raised, and charge-discharge magnification it is higher when heat up it is faster, especially for multiple cells composition device, temperature
Faster, this will affect optimum working performance and the life-span of battery, and cells burst is also resulted in when serious, or even occur quick-fried for aggregation
It is fried.Therefore, temperature control is very big to the performance impact of cell apparatus, and temperature is too high, too low and unbalanced can all affect battery
Performance, the ideal working temperature of lithium battery is adapted to hold within 50-60 DEG C, and more than 0 DEG C, the temperature difference should be at 5 DEG C or so.
To avoid the too high performance for affecting battery of temperature and life-span, need to be provided with cooling system in the battery, traditional dissipates
