Below with reference to accompanying drawing 1, accompanying drawing 2, the utility model is described further, but protection range of the present utility model should not be limited with this.
For convenience of description and understand the technical solution of the utility model, below illustrate that the orientation that the noun of locality used all is shown with accompanying drawing is as the criterion.
As shown in Figure 1, a kind of electric automobile power battery module 1, include several cells 2, the front of described cell, two sides, surface, five, bottom surface is all coated with UV glue insulation glue-line 3 below, several be coated with insulation glue-line battery cell between undertaken by UV insulating cement more mutually fastening, thus form a battery modules 1.
The battery module structure of prior art is as shown in Figure 2 compared, battery modules reliability of the present invention is higher, the glue-line of battery modules applying glue rear casing has a style of one's own, and with shell, there is good adhesive strength, fully can ensure the sealing of insulating barrier, simultaneously also corrosion-resistant, especially electrolyte resistance, and the unfailing performance such as high temperature resistant, high humidity can all be greatly improved.Also be convenient to production and processing, be beneficial to the raising of productivity ratio and the reduction of production cost.
During concrete enforcement, take following key step:
(1) single battery module shell frame seamed edge difference gluing is also used UV photocuring;
(2) by five faces gluing or glue spraying respectively, uniform bondline thickness is formed;
(3) by be coated with insulation glue-line battery cell between undertaken by UV insulating cement more mutually fastening, thus formed one insulation battery modules.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
