It is fixed.And can be used for multiple times, convenient for disassembly and assembly, good insulating, it is suitable for the shape of circular hole.
Further, a kind of heating structure of the battery modules with heating device, be mainly used in PACK cylindrical lithiums from
Sub- battery modules assembling procedure.During column lithium ion battery PACK system assembles, the mode of heatings of battery modules need through
The assembling procedure of module is crossed, the purpose of this process is so that 4 side surface of battery core is come into full contact with heating film 3, and added to battery core 4
Heat.
Since each module is individually to be heated, whole system will be composed in series by multiple modules, i.e., add multiple
Hotting mask 3 is connected, to carry out good heating to entire battery system.
The battery modules with heating device integrally use enclosed construction, i.e. battery modules both sides use material for ABS+
The holder 2 of PC fixes battery core 4, and due to being applied alone battery core 4 to fix heating film 3, the effect is relatively poor, then holder 2 is in fixed battery core 4
Heating film 3 can be also fixed simultaneously.
The material of the two external films of heating film 3 is polyamide, and heating film 3 is wrapped in 4 outer surface of battery core, for entire
Battery modules are heated.Plastic cement rivet 5 is a telescopic rivet arrangement, for fixing heating film.
And original heating film 3 is flat silica gel material, is attached to two sides of module, there is following ask in use
Topic：
Original heating film 3 cannot be in direct contact, and holder 2 due to being attached to PACK module brackets both sides with 4 surface of battery core
Heat-conducting effect unobvious, have a direct impact to the heating effect of battery.
Original heating film 3 is due to being silica gel material, and single-sided back-adhesive, ageing-resistant effect is not high, and there may be de- over time
Fall risk.
Original heating film 3 wastes the space of whole system, reduces space profit due to being to be attached to 2 outside of PACK module brackets
With rate, and practical operation is not very convenient.
The battery modules with heating device have the advantage that compared with original heating module：Each battery core 4 can be made heated
Uniformly, to make entire PACK systems heating effect improve；PACK internal systems space is saved, is substantially increased in PACK systems
The utilization rate in portion space；Production operation is simpler, conveniently, securely, reduces scrappage of the heating film in production operation, subtracts
Cost is lacked.
The present embodiment is according to a kind of battery modules with heating device provided by the utility model, for original heating film
3, the bad mode occurred in actual use designs a kind of new mode of heating, to solve original mode of heating
It causes to heat the problems such as uneven, the efficiency of heating surface is low and scrappage is high, to improve whole heating effect and the efficiency of heating surface.
Further, a kind of battery modules with heating device use the form of more than one piece cooperation, are provided to entire module
Heating film 3, i.e., be wrapped in inside battery modules by a kind of new battery modules heat form, makes itself and each battery core in module
It is all in contact, and heating effect is good, fixation is easy to operate, and scrappage is low.
Further, a kind of battery modules with heating device, chief component by holder 2, heating film 3, battery core 4 with
And plastic cement rivet 5 forms.The heating module 1 first swings in battery core 4 in holder 2 in assembling, can battery core 4 be first placed on second
In shell, the groove in 2 opposed two side walls of holder can play the role of battery core 4 fixed at this time, avoid battery core 4 from
It is fallen inside holder 2, carries out certain limit.
Then, heating film 3 is wound along the position that battery core 4 is put inside holder 2, and by heating film 3
One end is fixed on the side of holder 2 with plastic cement rivet 5 in advance, proceeds by winding.It is first shell by the holder 2 of the other side,
Cooperation is carried out with the second shell, battery core 4, heating film 3 installed before to fix.Use plastic cement rivet 5 by the heating of the other side again
Film 3 is fixed on holder 2.Entire heating module 1 is set smoothly to be assembled with other modules.
A kind of battery modules with heating device provided in this embodiment pass through the structure to original heating film 3, winding
The structures such as mode, fixed form are modified, and are solved battery core 4 and are heated difficult, uneven, 3 scrappage height of heating film of heating etc.
Some problems.
To make battery core 4 be heated evenly, heating effect is good, warm liter is apparent, and heating film 3 is conveniently operated, is fixed, section
Save space.Mode of heating in such new heating battery modules is the heating of cylindrical lithium-ion power battery PACK modules and whole
A PACK systems heating problems provide a kind of more preferable, higher mode.
Finally, the present processes are only preferable embodiment, are not intended to limit the scope of protection of the utility model.
Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in this reality
Within novel protection domain.
