In embodiments of the present invention, first fixed plate 110 is included for carrying out heating guarantor to the battery modules 130
First heating member 111 of temperature treatment.First heating member 111 is arranged in first fixed plate 110, with to the multiple
Heated one end that battery cell 131 is fixedly connected with first fixed plate 110.In an embodiment of the present embodiment
In, the gully shape lines for placing first heating member 111 is reserved with first fixed plate 110, described first adds
Warmware 111 is arranged in the gully shape lines, and first heating member 111 is embedded in into described first by gluing or cover plate
In fixed plate 110.
In the present embodiment, first heating member 111 is looped around the first through hole 113 weeks of first fixed plate 110
Enclose.When the battery cell 131 is fixedly connected by the first through hole 113 with first fixed plate 110, institute is looped around
First heating member 111 around first through hole 113 is stated to enter pair battery cell 131 corresponding with the first through hole 113
The treatment of row heating and thermal insulation, being distributed the heat of the battery modules 130 becomes uniform, and battery modules 130 described in fast quick-recovery are just
The working condition often run.
In the present embodiment, the density of first heating member 111 coiling around the different first through hole 113 is not
Together.Specifically, in the present embodiment, each battery cell 131 is by each self-corresponding different evenly distributed first through hole
113 are fixedly connected with first fixed plate 110, to constitute battery modules 130.When the battery modules 130 are applied to respectively
When planting different scene (such as, automobile cross bend), each battery cell 131 in the battery modules 130 can be with different
Multiplying power is discharged, and substantial amounts of heat is produced with different heat generation rate, but due to battery cell 131 be subject to it is corresponding described in
The restriction of first through hole 113, from the point of view of whole battery modules 130, heat skewness.
And due to battery cell 131 intensive for generating heat, rule is put and thermodynamic principles, in the battery modules
The heat of 130 zone line necessarily assembles more region, and the heat of the fringe region of the battery modules 130 compared with
It is few, will necessarily so produce the battery cell 131 on periphery in battery modules 130 and the battery list of the zone line of battery modules 130
There is the temperature difference between body 131, cause the inconsistent of the internal resistance of each battery cell 131 and capacity, and then cause percentage of batteries monomer
131 phenomenons that can produce overcharge or overdischarge, influence life-span and the performance of battery cell 131.
Therefore, in the present embodiment, the electricity of neighboring area of first heating member 111 in the battery modules 130
The density of the surrounding coiling of first through hole 113 corresponding to pond monomer 131 is more than first heating member 111 in the battery modules
The density of the surrounding coiling of first through hole 113 corresponding to the battery cell 131 of the zone line in 130, specific layout type
Can refer to Fig. 3 and Fig. 4.First heating member 111 is more than described in the heat that the neighboring area of the battery modules 130 produces
The heat that first heating member 111 is produced in the zone line of the battery modules 130, so that the heat of the battery modules 130
Distribution becomes uniform, progressively recovers the working condition that the battery modules 130 are normally run.
In the present embodiment, first heating member 111 includes at least two heater strips, at least two heater strip phases
The composition that connects first heating member 111.
In the present embodiment, the heating power of at least two heater strips in first heating member 111 is different.With it is above-mentioned
The coiling around the different first through hole 113 of the first heating member 111 density it is different similar, constitute first heating
Corresponding to the battery cell 131 of the neighboring area at least two heater strips of part 111 in the battery modules 130 first
The heater strip of the surrounding coiling of through hole 113 belongs to heating power heater strip higher, in the battery in first heating member 111
