Accompanying drawing explanation
Below with reference to drawings and Examples, technical scheme of the present invention is described in further detail, wherein:
Fig. 1 is provided with the structural representation with an embodiment of battery cell of conductive structure of the present invention.
Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.Should be understood that, the detailed description of specific embodiment is used for to description and interpretation the present invention, but is not limited to the present invention.
An example structure schematic diagram of battery cell with conductive structure has been shown in Fig. 1.Battery cell 1 comprises negative terminal 2, positive terminal 9, at least two cell pieces 3 and 5, heat conducting element 4 and housings 8.Housing 8 is shells of battery cell, for the protection of the cell piece in battery cell.Negative terminal 2 and positive terminal 9 are arranged on the upper surface 10 of housing 8, and it is connected with 5 with cell piece 3 by plate.
Heat conducting element 4 can be by making such as suitable Heat Conduction Materials such as aluminium.For joint space-efficient object, heat conducting element is designed to thin tablet or plate object, it is disposed between cell piece 3 and 5 for absorbing the heat distributing on cell piece in the present embodiment, and the area of heat conducting element should be large as far as possible, preferably can cover the area of whole cell piece.For the object that prevents from disturbing cell piece, the surface of heat conducting element and cell piece laminating must be done electric insulation and be processed, for example by sputter or lamination or spraying or its associated methods, form the electric insulation layer with surperficial close attachment on the surface of heat conducting element, the special polymer that heat conductive insulating layer can be filled by certain pottery form.
During battery operated, the heat conducting element being clamped absorbs the heat on cell piece, and is transmitted to surrounding by heat conducting element self.The surface of the heat conducting element after electric insulation is processed can be smooth smooth, also can be designed to coarse surface so that better dissipation of heat is gone out.From Fig. 1, can see, in order to prevent interfering with the terminal of housing 8 one end, stretch out from the lower surface 6 of housing 8 one end of heat conducting element 4, and acting as of this external part 7 passes to by heat the object that other object reduces to realize better battery cell core temperature.In order as early as possible the heat in battery core body to be shed, external part 7 and center heat transfer distances are designed to the shortest as far as possible.According to different needs, this external part can be connected with other object, such as heat recovery system or radiator etc.If when battery cell need to heat, heat conducting element external part conducts the heat and can directly conduct to cell piece, has so both reclaimed part heat simultaneously, reached again the object that battery cell is heated up.
It should be understood that the heat conducting element in the present embodiment is not limited to one, the quantity of heat conducting element depends on the concrete quantity of cell piece, and according to different actual conditions, the quantity of heat conducting element can be two, three, four, five or more.
Due to the battery cell with conductive structure of the present invention and battery have compact conformation, heat exchange efficiency high, be easy to the many advantages such as manufacture, be therefore very suitable for being applied.For example, battery of the present invention can be set on automobile, to obtain foregoing advantage.Especially it is to be noted, on such as pure electric vehicle or hybrid electric vehicle, can configure the vehicle mounted dynamic battery of having applied battery of the present invention, thereby contribute to extend this vehicle mounted dynamic battery useful life, reduce long-term use cost, improve usage safety performance, and can promote the energy utilization efficiency of battery, and then extend the whole course continuation mileage of these vehicles.
More than enumerate specific embodiment and elaborated the have battery cell of conductive structure, the automobile that disposes the battery of described battery cell and be provided with described battery of the present invention, this embodiment is only for explanation structure of the present invention, and be not limitation of the present invention, the those of ordinary skill in relevant technologies field, without departing from the present invention, can also make various distortion and improvement, therefore all technical schemes that are equal to also should belong to category of the present invention and be limited by every claim of the present invention.
