Description
Technical field
This application involves battery technology fields, and in particular to a kind of good battery pack of heat dissipation.
Background technology
New-energy automobile is greatly developed in China, it is contemplated that the ownership to the year two thousand twenty new-energy automobile is up to
5000000.Accumulator is also increasingly being applied to the occasion of the high power works such as electric vehicle.In practical occasion, accumulator
Mostly by single battery series connection and/or and use in the form of being unified into battery pack, the quantity of series/parallel from tens to, hundreds of very
It is differed to thousands of.For security protection and the requirement of installation, battery pack is typically disposed in shell made of metal, and outside is equipped with
Terminal.Space is used in order to improve the effective of automobile, it is desirable to reduce battery pack volume, single battery are often arranged very tight
Close, this is very unfavorable for the heat dissipation of battery pack.In latter stage of charging and high power work, internal storage battery meeting heat release, battery
The temperature of the single battery in group centre position will be apparently higher than the temperature of the single battery close to shell wall, the electrification that they show
Characteristic is different from other batteries, and the battery homogeneity obtained before assembling by a variety of effort has not just existed, this portion in use
Divide single battery that will soon be operated in overcharge, cross and put under state, performance fails rapidly, and failure is caused under whole group battery performance
Drop even failure, failure.Dissection and analysis by the accumulator group to end to cycle life also indicates that battery pack medium temperature height
Single battery the residual capacity single battery low well below battery pack edge temperature residual capacity, battery pack
Failure is mainly due to caused by battery pack middle part the part often failure of the single battery under high temperature.This results in electricity
The service life of pond group is significantly less than the cycle life of single battery.Moreover, because also contained significant proportion in discarded battery pack
The single battery for still having use value, also result in the waste of resource and the increase of use cost.
In order to improve the situation of single battery non-uniform temperature existing for battery pack use in the process, and then improve battery pack
Service life, there has been proposed various solutions.Plus various cooling devices such as in battery pack, wherein to be made with air
For cool down medium air cooling equipment and by the use of water as cool down medium water cooling plant it is relatively conventional.But both modes there is
The deficiency of additional cooling medium circulating apparatus is needed, providing the device such as wind turbine, water pump of medium circulation power needs to expend in itself
Electric energy and occupied space will also reserve cooling medium channel in battery pack, this will increase the volume of battery pack, limit electricity
The riding position of pond group onboard.Also, after stopping, if turned off the power supply on vehicle, the devices such as wind turbine, water pump will stop work
Make, it is impossible to ensure being fully cooled for battery pack.It is just closed on wind turbine, water pump and vehicle after battery pack is fully cooled to realize
Power supply then will substantially increase the complexity of electrical control, improve cost.
