Referring to Fig. 1, Fig. 1 is the theory diagram for the battery pack 100 that embodiment of the present utility model provides.The battery pack
100, which include multiple temperature of battery core 10 and first, becomes device 20.First temperature, which becomes device 20, includes multiple accepting units 26.Each electricity
Core 10 is contained in accepting unit 26 corresponding to one.Each accepting unit 26 is more than the first reference value and less than the second reference in temperature
Heat is conducted during value, and is blocked when temperature is less than or equal to first reference value or more than or equal to second reference value
Heat exchange.
In the present embodiment, each accepting unit 26 is in U-typed channel-shaped.Each battery core 10 houses list corresponding to being contained in
In member 26, and the volume of each battery core 10 is less than or equal to the volume that corresponding accepting unit 26 surrounds space.Each battery core
10 be substantially in cuboid-type, and the U-typed opening direction of adjacent two accepting units 26 is opposite.In other embodiments, phase
The U-typed opening direction of two adjacent accepting units 26 can be with identical；Each accepting unit 26 can be other shapes, such as rectangular
The gengon such as body shape, cylindric etc.；The battery core 10 can be other shapes, such as cylinder.
The battery pack 100 also includes heater 30.When temperature is less than or equal to three reference values, the heating dress
30 are put to begin to warm up.When temperature is more than first reference value, the heater 30 stops heating.3rd reference value
Less than first reference value.
The battery pack 100 also includes casing 50.The casing 50 includes bottom plate 51 and is arranged on the bottom plate 51
Four side plates 55 at edge.The bottom plate 51 surrounds with four side plates 55 houses the multiple battery core 10, first temperature
Become the receiving space of device 20 and the heater 30.The heater 30 is arranged on first temperature and becomes device 20 and institute
State between bottom plate 51.
The battery pack 100 also includes the second temperature and becomes device 60.Second temperature becomes device 60 and is arranged on the heating dress
Put between 30 and the bottom plate 51.Second temperature becomes device 60 and is more than first reference value and less than described second in temperature
Heat is conducted during reference value, and when temperature is less than or equal to first reference value or more than or equal to second reference value
Block heat exchange.
It is appreciated that in the present embodiment, first reference value, second reference value and the 3rd reference value
Concrete numerical value can be adjusted correspondingly according to actual conditions.
The operation principle of the battery pack 100 provided embodiment of the present utility model is illustrated below.
When each 10 equal normal work of battery core, due to individual difference between battery core 10 be present, caused by each battery core 10
Heat is different, but the temperature of each battery core 10 can be between first reference value and second reference value.It is each to house list
Member 26 is almost identical with the temperature for the battery core 10 that it is housed, i.e. the temperature of each accepting unit 26 is more than first reference value
And it is less than second reference value.Now, each accepting unit 26 shows the high conduction characteristic to heat, quickly and can have
Effect ground conduction heat, so that the temperature of each battery core 10 is roughly the same, and then enhances battery core 10 in the battery pack 100
Uniformity and the service life for extending the battery pack 100.
When some 10 thermal runaway of battery core, the battery core 10 gives out substantial amounts of heat, houses the receipts of the battery core 10
Hold the rapid absorption of unit 26 and conduct the heat that the battery core 10 gives out.Described in being more than when the temperature of the accepting unit 26
During the second reference value, the accepting unit 26 shows the high resistant characteristic to heat, can effectively block heat exchange, so as to have
Prevent that high fever is conducted to adjacent battery core 10 by adjacent accepting unit 26 caused by the battery core 10 to effect, and then effectively
Avoid chain reaction caused by the thermal failure of battery core 10 and enhance the security of the battery pack 100.
When the temperature in the casing 50 is less than three reference value, battery core 10 is influenceed in order to prevent temperature too low
Normal work, the heater 30 begins to warm up.Now, first temperature becomes device 20 and second temperature becomes device 60
All show the high resistant characteristic to heat.Each accepting unit 26 blocks the heat exchange of corresponding battery core 10, so as to play insulation
Effect.Second temperature becomes device 60 and blocks the heater 30 to carry out hot friendship by the bottom plate 51 and external environment
Change, so that heat caused by the heater 30 can more be used to heat the multiple battery core 10, reduce heat
Loss, improve the utilization rate that the heater 30 produces heat.When the temperature in the battery case is more than the described first ginseng
When examining value, the heater 30 stops heating.
The utility model by the multiple battery core 10 by being contained in the described first warm multiple accepting units for becoming device 20
In 26, and when temperature is more than first reference value and is less than second reference value, conduction is hot using each accepting unit 26
Measure, and the spy of heat exchange is blocked when temperature is less than or equal to first reference value or more than or equal to second reference value
Property, so that during each 10 normal work of battery core, corresponding accepting unit 26 can quickly and efficiently conduct heat, so that often
The temperature of individual battery core 10 is roughly the same, and then enhances the uniformity of battery core 10 in the battery pack 100 and extend the electricity
The service life of pond group 100；And in some 10 thermal runaway of battery core, corresponding accepting unit 26 can effectively block hot friendship
Change, so as to effectively prevent that high fever is conducted to adjacent battery core 10 by adjacent accepting unit 26 caused by the battery core 10,
And then it efficiently avoid chain reaction caused by the thermal failure of battery core 10 and enhance the security of the battery pack 100.
The utility model is not restricted to described in specification and embodiment, therefore for the personage of familiar field
For additional advantage and modification is easily achieved, therefore in the universal limited without departing substantially from claim and equivalency range
Spirit and scope in the case of, the utility model is not limited to specific details, representational equipment and shown here as with retouching
The examples shown stated.
