Description
Technical field
The utility model relates to a kind of from heating battery module.
Background technology
Develop rapidly along with China's economic construction; Secondary cell has all had widely in all trades and professions to be used, and especially in fields such as electric automobile, Electric aircrafts, lithium rechargeable battery is because its specific energy is big; Safe, advantages such as green non-pollution are by high-frequency application gradually.In practical application,, combine by some batteries and interlock circuit and to constitute battery module for satisfying battery management and requirement easy for installation.Because battery is relatively more responsive to ambient temperature, particularly evident in big capacity, the application of high-power secondary cell, too high or too low temperature all can influence battery charging and discharging performance and useful life.Present battery module has mostly increased corresponding heat dissipation for battery unit, can avoid it under excessive temperature, to work.And how to make battery module normal use under cryogenic conditions, and never having good solution, this also is one of problem of those skilled in the art active research.Application number is that 200920246448 Chinese patent file " a kind of novel battery case " discloses a kind of battery case, and electric heating material directly is installed on cabinet wall.This mode steadiness is poor, and electric heating material is installed on inwall has certain difficulty, and heating material touches battery easily when being shaken, and may damage battery.
The utility model content
The purpose of the utility model provides a kind of from heating battery module, in order to solve prior art the problem of heating material mode steadiness and poor stability is installed.
For realizing above-mentioned purpose; The scheme of the utility model is: a kind of from heating battery module; Comprise outer casing; Be provided with the battery unit and the electric heater unit that is used for from heating that are used to install electric core in the outer casing, also be provided with between outer casing and the battery unit and the suitable internal layer shell of battery unit volume, internal layer shell detachably is fixedly connected with outer casing; Be provided with the plough groove type fixed head between internal layer shell and the outer casing, said electric heater unit is installed in the groove of said plough groove type fixed head.
Said plough groove type fixed head is fixed on the lateral wall of said internal layer shell.Damping and insulation material are installed on the outer casing madial wall.Be equipped with on the said outer casing and be used for the electric connector that is connected with external equipment, this electric connector is connected with said battery unit through the protective circuit plate.Be provided with the insulation fixed head that is used for spacing electric core between said protective circuit plate and the battery unit.
On the plough groove type fixed head between internal layer and the outer casing electric heater unit is set, easy for installation, firm, and because for battery unit has increased an internal layer shell, so electric heater unit can not injure battery unit because of vibrations.In addition, internal layer shell and outer casing removably connect fixing, have solved the problem that battery unit installs and fixes, and install and use very convenient; The plough groove type fixed head can also play the effect of reinforcing.Increase insulation and vibration-absorptive material beyond the electric heater unit, improved the environmental suitability of battery module, it can be worked in the low temperature environment of harshness.Simultaneously, battery module uses the electric connector of standard, has also increased its practicality.The battery of the utility model can normally use in low temperature environment, and is simple in structure, installation and easy to maintenance.
Description of drawings
Fig. 1 is the outside drawing of the battery module of the utility model;
Fig. 2 is the perspective view after the battery module of the utility model decomposes;
Fig. 3 is the perspective view after the endothecium structure of the utility model decomposes.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Like Fig. 1, shown in Figure 2; In the present embodiment, battery module 1 comprises endothecium structure 6 and layer structure, and endothecium structure 6 comprises the battery unit 10 of assembling in internal layer shell 11 and the internal layer shell 11; Layer structure comprises outer casing 7, and internal layer shell 11 is connected with the detachable mount of outer casing.Battery module ectonexine structure is hard shell, and internal layer shell 11 preferred heat conduction are good, the metal of lighter weight, outer casing 7 preferred intensity good metal or resin material etc.
As shown in Figure 3; Be fixed with plough groove type fixed head 12 on the lateral wall of internal layer shell 11; In the groove of plough groove type fixed head 12 electric heater unit is installed, electric heater unit can also can be from the external power supply power taking from the power taking of battery module own, electric heating materials such as the preferred PTC of material of electric heater unit.In addition, plough groove type fixed head 12 can also play the effect of reinforcing internal layer shell 11.Outer casing 7 inboards also are equipped with insulation and vibration-absorptive material, and preferred insulation property are good, combustion-supporting, the flexibly thermal insulation material of damping, like EVA etc.Be equipped with on the outer casing 7 and be used for the electric connector 2 that is connected with external equipment, electric connector 2 is connected with the output of battery unit 10 through protective circuit plate 8.
Certainly, the utility model can also have other numerous embodiments, also can be fixed on the inboard of outer casing 7 like plough groove type fixed head 12.Under the situation that does not deviate from the utility model spirit and essence thereof, those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these changes and distortion should belong to the protection range of the appended claim of the utility model.
