Abstract
The invention discloses a heatable battery box. The heatable battery box comprises a box body (1) and batteries (2), and further comprises an electric heating wire (3), wherein the batteries (2) and the electric heating wire (3) are arranged inside the box body (1); and the electric heating wire (3) is arranged in a mounting gap between the batteries (2). The electric heating wire (3) further can be replaced by an electric heating belt. According to the heatable battery box disclosed by the invention, the problems of a complex structure and low efficiency of the heatable battery box in the prior art are solved, and the heatable battery box disclosed by the invention is mainly applied to the heating and thermal insulation fields of the battery box of an electric vehicle.
Description
Technical field
The present invention relates to battery case field, particularly relating to one can heating battery case.
Background technology
Current motor vehicle needs with a large amount of electrokinetic cells, current electrokinetic cell mainly uses liquid electrolyte, because liquid electrolyte easily condenses when low temperature, activity decrease, thus electrokinetic cell discharge performance is declined, even destroy barrier film, cause the injury of electrokinetic cell destructiveness, particularly electric vehicle applications cold local time, indoor and outdoor temperature is far below zero degree, if do not carry out heating and thermal insulation to battery, battery is easy to damage, therefore, design a kind of can the battery case of heating and thermal insulation, just the technical problem that current motor vehicle is badly in need of solving is become.
For this problem, have the design of arranging electric blanket around battery case at present, because electric blanket is in the border of high/low temperature, heat is easily dispersed into the external world, and thermal loss is large, and efficiency is low, and battery case inside is heated uneven, and middle cell is difficult to obtain heat.
For this problem, also have at present and adopt liquid state to heat, because liquid state heating needs to arrange complicated pipeline, and need to arrange heater and circulating pump, the fault point of electrokinetic cell system must be increased, the cost of increase motor vehicle.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides one can heating battery case, and it is simple that the present invention has structure, the advantage that efficiency is high.
The present invention solves its technical problem and a kind of technical scheme of adopting is: one can heating battery case, comprise casing, battery, also comprise heating wire, described battery, heating wire are arranged on described box house, and described heating wire is arranged in described battery and battery assemblage gap each other.
Further, described heating wire is can free bending heating wire.
Further, described heating wire is circular silica gel electric heating wire.
Further, described circular silica-gel electrothermic linear diameter≤10mm.
Further, each side of described casing is provided with heat-insulation layer.
Further, described cabinet insulation layer is provided with three layers, and the material of each layer is followed successively by metal, foamed silica gel, PP plastics from outside to inside.
Further, described battery is cylindrical battery, the stacked installation of described cylindrical battery, forms assemblage gap in the middle of every four.
Operation principle of the present invention is, described heating wire is whole piece heating wire, the assemblage gap mutual from battery passes, bending is roundabout, thus go over each assemblage gap, because heating wire length direction caloric value is equal, thus battery case various places inside can be made to be heated relatively uniform, and described casing is provided with heat-insulation layer, battery case internal temperature thus can be made to remain on a suitable scope.
The present invention solves its technical problem and the another kind of technical scheme that adopts is: one can heating battery case, comprise casing, battery, also comprise ribbon heater, described battery, ribbon heater are arranged on described box house, and described ribbon heater is arranged in described battery and battery assemblage gap each other.
The invention has the beneficial effects as follows, structure is simple, and efficiency is high.
Accompanying drawing explanation
Fig. 1 is that one of the present invention can heating battery box structure schematic diagram.
The implication marked in Fig. 1 is: 1. casing, 2. battery, 3. heating wire, and in figure, heating wire section belt fork represents that vertical paper penetrates, and section belt round dot represents that vertical paper passes.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In the embodiment shown in fig. 1, it is inner that battery 2, heating wire 3 are arranged on casing 1, and heating wire 3 passes from the assemblage gap of battery 2.
In embodiments of the invention, heating wire 3 is can free bending heating wire, thus can be roundabout continuously at the assemblage gap everywhere of battery 2, thus goes over each assemblage gap.
Heating wire cladding material of the present invention can be the insulating material such as silica gel, PVC, Teflon, and profile also can be various shape, and in embodiments of the invention, heating wire 3 is preferably circular silica gel electric heating wire.
In embodiments of the invention, circular silica gel electric heating wire 3 Zhi Jing≤10mm.
In embodiments of the invention, each side of casing 1 is provided with heat-insulation layer.
In embodiments of the invention, casing 1 heat-insulation layer is provided with three layers, and the material of each layer is followed successively by metal, foamed silica gel, PP plastics from outside to inside.
In embodiments of the invention, battery 2 is cylindrical battery, the stacked installation of cylindrical battery 2, forms assemblage gap in the middle of every four.
The operation principle of embodiments of the invention is, heating wire 3 is whole piece heating wire, the assemblage gap mutual from battery 2 passes, bending is roundabout, thus go over each assemblage gap, because heating wire 3 length direction caloric value is equal, thus battery case various places inside can be made to be heated relatively uniform, and casing 1 is provided with heat-insulation layer, battery case internal temperature thus can be made to remain on a suitable scope.The heat-preserving range that can set battery case is 10 degree to 35 degree, and when internal temperature is lower than 10 degree, heating wire 3 is powered by the external world and heated, and quits work when arrival 35 degree, iterative cycles work like this.
In another embodiment of the present invention, heating wire (3) is replaced to have equivalent effect with ribbon heater.
The beneficial effect of embodiments of the invention is that the simple efficiency of structure is high.
The above is only the description of the preferred embodiment of the present invention; should be understood that the finiteness due to literal expression; and objectively there is unlimited concrete structure; for this area those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improvement also should be considered as protection scope of the present invention.
