Description
Technical field
The invention belongs to the electric supply installation field, relate to a kind of power source, specifically a kind of battery pack.
Background technology
Power car, for example, hybrid vehicle need use multiple propulsion system to come to provide power for it.The modal oil-electricity mixed power automobile that is, it uses gasoline (diesel oil) to drive explosive motor (internal combustion engine), and electrokinetic cell comes drive motor.This class hybrid vehicle comes to be power battery charging by the braking kinetic energy of catching regeneration.Under normal smooth-ride or idling conditions, some outputs that fuel oil starts can feed back to generator (being that motor operates under the power generation mode), the electric energy that produces are used for the charging of battery.Different therewith is that the battery of pure electric automobile then needs outside power supply, for example electrical network, perhaps a Wai Bu charging station.
Battery then is very important known energy storage component.Battery or electric core comprised positive and negative electrode and between the conduction ion electrolyte.Battery pack particularly uses the battery pack of lithium ion chargeable owing to possessing, and does not have the characteristic of Memorability, and it is become more and more popular in automobile application and the electric apparatus field of various commerce.Storage and operation lithium ion battery under the working temperature an of the best, charging performance of battery and effective extending battery life are most important for keeping.According to the characteristic of lithium ion battery, the operating ambient temperature range of lithium battery group is-20～60 ℃, even but within this operating temperature range, the capacity of battery pack or charging and discharging capabilities also can lower.According to test, when ambient temperature at 0 ℃ up and down the time, real-time circulation volume and the charging and discharging capabilities of battery pack just can reduce significantly.In addition, when ambient temperature continued to be higher than 35～40 ℃, the life-span of battery also can significantly reduce.However, lithium ion is can't avoid being operated under the environment that exceeds operating temperature range moving.
In fact, pointed as top situation, the tangible temperature contrast between battery/electric core is only the basic reason of damaging battery performance.Therefore, in order to improve the life-span of whole battery group, guarantee that every battery in the battery pack all will be worked in operating temperature range.In order to improve the overall performance of battery pack, also to reduce the temperature difference between cell/electric core as far as possible.But because the difference of the heat dissipation path of each battery, different cells also has different temperature.In addition, for the same reason, different cells can reach different temperature in charging process.Therefore, if the temperature of one of them battery when relatively the temperature of other battery is higher, its efficiency for charge-discharge will be different, and for example, it may be faster than other battery charging and discharging speed.This situation can cause the performance of entire cell bag to descend.
