Description
The technical field is as follows:
the invention relates to a heating battery module, and belongs to the technical field of battery thermal management.
Background art:
when the power lithium ion battery is used, the normal use of the power lithium ion battery can be ensured only at a proper temperature. At a lower temperature, the chemical reaction activity of the battery is reduced, lithium ions are removed from a positive electrode in the charging process and are transferred and embedded into a negative electrode material through electrolyte, the lithium ion transfer is slow, the lithium ions on the surface of the negative electrode are not embedded into the negative electrode and are reduced into metal lithium and precipitated and separated out on the surface of the negative electrode to form lithium dendrites, and safety accidents are easily caused. Therefore, it is necessary to perform a preheating process before charging in a low-temperature environment.
Cylindrical electric core is because its special circular structure, and a common heating methods adopts PI (polyimide) heating plate snakelike winding to heat on electric core circumference, simple structure, and economic nature is good. The following problems are found in practical applications:
the snake-shaped winding structure is difficult to assemble, cannot be effectively positioned and has poor process operability; meanwhile, the thickness of a general PI (polyimide) heating plate is less than 0.3mm, when the gap interval between the battery cores is 1-2 mm, the contact circumferential angle is about 30 degrees, and the contact area is small; the contact area of the heating sheet and each battery cell can not be ensured to be consistent, so that the heating temperature uniformity is poor.
Therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.
The invention content is as follows:
the present invention provides a heating battery module to solve the above problems of the prior art.
The technical scheme adopted by the invention is as follows: the utility model provides a heating battery module, includes electric core, installs respectively before electric core, the rear end and carry out fixed cooperation support, silica gel piece and PI type heating plate with electric core, electric core is cylindrical, and the face of cylinder of electric core closely laminates mutually with PI type heating plate, and silica gel piece and electric core parallel arrangement and silica gel piece closely laminate mutually with PI type heating plate.
Furthermore, the PI type heating plate is of a three-layer structure, the middle of the PI type heating plate is a metal heating plate, and the two layers of the PI type heating plate are PI thin film sheets.
Furthermore, the metal heating plate is made of nickel-chromium alloy and copper foil.
The invention has the following beneficial effects: the heating battery module can ensure that the contact area of the heating sheet and each battery cell is consistent, and the heating temperature uniformity is good.

The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
The heating battery module comprises an electric core 1, a matching support 2, a silica gel block 3 and a PI type heating sheet 4, wherein the matching support 2 is respectively arranged at the front end and the rear end of the electric core 1 and used for fixing the electric core 1, the electric core 1 is cylindrical, the cylindrical surface of the electric core 1 is tightly attached to the PI type heating sheet 4, the silica gel block 3 is arranged in parallel with the electric core 1, and the silica gel block 3 is tightly attached to the PI type heating sheet 4.
The PI type heating plate 4 is of a three-layer structure, and the middle part is a metal heating plate 5 which is usually made of nickel-chromium alloy, copper foil and the like; the two layers on the outer side are PI (polyimide) film sheets 6 which are organic high polymer materials, are high temperature resistant, have a long-term use temperature range of-200-300 ℃, and have good insulation and voltage resistance.
The silica gel block 3 in the heating battery module has higher heat conductivity coefficient, and when the PI type heating plate 4 is wound on the battery core 1 in a snake shape, the PI type heating plate is extruded and filled with pasty silica gel, or the PI type heating plate is directly solidified into the silica gel block 3 and then assembled. A plurality of heterotypic silica gel blocks 3 are a set of subassembly, guarantee after the equipment that the area of contact of each electric core 1 and PI type heating plate 4, silica gel subassembly is unanimous.
When needing to preheat for the battery package in low temperature environment, let in certain electric current to PI type heating plate 4, send the heat, pass through silica gel piece 3 with the heat indirect or directly give electric core 1 with the contact surface of electric core 1 heat transfer fast for electric core preheats. Meanwhile, heat among the electric cores 1 can be balanced through the silica gel blocks 3, and the temperature rise of the electric cores 1 is consistent.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
