Description
Technical field
The present invention relates to field of batteries, more particularly to a kind of battery module.
Background technology
With the proposition of the related new energy laws and regulations of country, the development of new-energy automobile is to alleviate the energy and environment pressure
Power, promote the important measure of automobile industry sustainable development.New-energy automobile includes pure electric automobile, plug-in hybrid vapour
Car, hybrid vehicle etc..Wherein pure electric automobile is the automobile for providing power source by battery completely, with its environmental pollution
The advantages of small, and course continuation mileage is long, there is good prospect.
Pure electric automobile is due to the more electricity of demand, and voltage needs to match with motor, therefore between usually requiring battery
Parallel connection is carried out, while battery bag energy is improved, does not improve the voltage of battery bag.
When two or more battery units are combined into battery pack, it is difficult to maintain the dimensionally stable of battery pack
Property, when battery pack is by strong external impact and vibration, battery unit produces loosening in battery pack, as a result the safety of battery pack
Property and durability reduce.
There is the edge part formed by two panels aluminum plastic film or steel plastic film hot pressing the edge of soft-package battery, and edge part is soft
There is no Essential Action on bag battery but be not eliminable part, and edge part is easily bent or torn, and even results in electricity
The damage of pond body.The method that soft-package battery typically uses in groups at present is：The soft-package battery of certain amount is placed in one first
Individual shape is similar in the battery case of box or chest, and the lug of soft-package battery then is carried out into company in series or in parallel again
Connecing, the size of this battery case is greater than the thickness of the length of soft-package battery, width and the superposition of multiple soft-package batteries and formation,
Final total lug (collector) extends chest.A soft package battery module is so just formed, then again by multiple Soft Rolls electricity
Pond block combiner forms soft-package battery bag.
Some shortcomings be present in above-mentioned this design, first, the combination of the size of battery case than multiple soft package battery modules
Size it is big, the volume energy density for being assembled into whole module after battery module is relatively low；Secondly, multiple Soft Rolls in battery case
Battery is usually to be superimposed, typically no fixed structure between soft-package battery, in use, due to jolting or shaking
It is dynamic, relative displacement may occur between soft-package battery, so as to produce the extruding of battery cell or lug or kinking so that whole
The reliability of individual battery module reduces；In addition, after multiple soft-package battery superpositions, easily causing the cell heat of centre can not dissipate
Go out, cause whole battery unit heat distribution uneven.
The content of the invention
In view of problem present in background technology, it is an object of the invention to provide a kind of battery module, and it can strengthen electricity
The fixing intensity of pool unit, improve the heat-sinking capability and energy density of battery module.
To achieve these goals, the invention provides a kind of battery module, it includes：Heat sink；Battery unit, at least
It is fixed on along an end face of orientation on heat sink；And two fixed mounts.Wherein, two fixed mounts are fastened by elasticity
Link together, and battery unit and heat sink are clamped between two fixed mounts.
Beneficial effects of the present invention are as follows：
In the battery module according to the present invention, two fixed mounts are fastened by elasticity to grip battery unit, nothing
Larger-size battery case, therefore the effective volume for reducing battery module need to be provided as prior art, improve battery module
Energy density；Meanwhile at least one end face of battery unit is fixed on heat sink, so heat sink can carry for battery unit
For extra fixation, moreover it is possible to heat transfer caused by battery unit effectively is avoided into battery unit thermal runaway to outside.
