Abstract
The utility model discloses a heatable battery module of electric automobile, include battery module and the electrical heating membrane that forms by a plurality of battery monomer stacks, the electrical heating membrane includes the electrical heating membrane monomer that a plurality of parallelly connected electricity are connected, and the free one side of electrical heating membrane is equipped with pastes the layer, pastes the layer and pastes and fix on battery monomer surface. The utility model adopts a heating structure with a plurality of electric heating film monomers electrically connected in parallel, and fixes the electric heating film monomers by using a pasting mode, thereby not only heating the battery monomers one by one, but also leading the electric heating film monomers to extend into the battery module to heat the battery module, and further leading the heat to be evenly distributed, leading the interior of the battery module to be evenly heated, and improving the heating efficiency of the battery module; in addition, the electric heating film monomer is installed and fixed by using a sticking mode, so that the heating structure is simplified, the installation and fixing part of the existing heating device is omitted, the volume of the whole power battery is reduced, and the structure of the automobile power battery is more compact.
Description
Technical field
The utility model relates to auto parts and components, refers to the heatable battery modules of a kind of electric automobile particularly.
Background technology
When the temperature of powered cell on electric automobile is lower than zero degree, freeze for preventing battery fluid or battery functi on reduction, consider from security standpoint, need forbid charging the battery, this is limited in the use of low temp area with regard to causing electric automobile.At present, cell production companies many employings heater heats whole battery modules, there is following shortcoming in existing heater: when 1) heater heats battery modules, battery cell often near heater side is first heated, be heated after battery cell away from heater side, heat conducts gradually successively in battery modules, cause battery modules internal cell monomer to be heated uneven, and the efficiency of heating surface is also lower; 2) heater general structure is complicated, volume is comparatively large, adds battery production technology difficulty.
Summary of the invention
The purpose of this utility model will provide a kind of electric automobile heatable battery modules exactly, and this battery modules self has heating function, and battery modules inside is heated evenly, and the efficiency of heating surface is high.
For achieving the above object, the technical solution adopted in the utility model is: the heatable battery modules of a kind of electric automobile, comprise the battery modules be laminated by multiple battery cell, also comprise electric heating film, described electric heating film comprises the electric heating film monomer of multiple parallel connection electrical connection, the side of described electric heating film monomer is provided with adhered layer, and described adhered layer is pasted and fixed on described battery cell surface.
The utility model abandons the integral type heater of existing complexity, adopt the heating arrangement of multiple electric heating film monomer parallel connection electrical connection, and profit in the method for paste to electric heating film monomer carry out installation fix, not only can heat one by one the battery cell of battery modules, but also make electric heating film monomer can stretch into battery modules inside it is heated, and then even heat distribution, battery modules inside is heated evenly, improves the efficiency of heating surface of battery modules; In addition, utilize bonding method to carry out installation to electric heating film monomer and fix, not only simplify heating arrangement, also eliminate the mounting fixing parts of existing heater, and then reduce the volume of whole electrokinetic cell, make automobile power cell structure more compact, battery production technology is good.
Further, in the form of sheets, and described electric heating film monomer is pasted onto the side of described battery cell to described electric heating film monomer by described adhered layer.Adopt the electric heating film monomer of sheet, make electric heating film monomer can be pasted on battery cell surface, planar heating more properly, improve each battery cell heating consistency, battery modules inside is heated evenly.
Further, described battery cell is the cuboid battery cell comprising the first side and the second side, described battery modules is laminated by described first side and described second side by multiple described battery cell, and described electric heating film monomer is pasted onto on described first side of described battery cell by described adhered layer.This arrangement make stacked enter battery modules inside the first side on be also pasted with electric heating film monomer, thus battery modules internal cell monomer is heated evenly, avoid the side heat that existing heating devices heat produces, the phenomenon that opposite side is cold, improves the efficiency of heating surface; And electric heating film monomer is all pasted onto on the first side of battery cell in battery modules, being to make electric heating film monomer be uniformly distributed in battery modules, promoting being heated evenly property of battery modules inside further.
Further, described electric heating film monomer is polyimides Electric radiant Heating Film, and described adhered layer is FEP adhered layer.
