Technical Field

The utility model relates to an electricity core normal discharge structure under low temperature environment.

Background

In the prior art, the lower the temperature is, the less the capacity released by the battery core is, the higher the power consumption speed is, and the requirements cannot be met when the battery is used in winter or in a low-temperature environment.

Disclosure of Invention

The utility model discloses improve above-mentioned problem, promptly the to-be-solved technical problem of the utility model is that the capacity that the temperature is lower electric core release is less more, and power consumptive speed is faster, and the life-span reduces.

The utility model discloses a concrete implementation scheme is: the utility model provides a normal discharge structure of electric core under low temperature environment, includes that electric core and attached in the heating subsides at electric core back, the heating is pasted the interior copper foil that is equipped with of interior cloth, the copper foil is connected with the power and is used for heating for electric core.

Furthermore, the heating paste also comprises insulating rubber sheets positioned on two sides of the copper foil, and the surface of the insulating rubber facing one side of the battery cell is provided with dotted glue for realizing the pasting of the heating paste and the battery cell.

Furthermore, the copper foil is continuously and uniformly bent between the two insulating rubber sheets, and power contacts are formed at two ends of the copper foil.

Furthermore, the two sides of the heating paste are provided with bent buckling strips which are buckled on the two sides of the battery core.

Furthermore, a circuit protection board is fixedly connected to the top of the battery core.

Compared with the prior art, the utility model discloses following beneficial effect has: simple structure, few matching parts, simple manufacture, low economic cost and contribution to mass production. Thereby improve electric core week side temperature through the heating of copper foil to make electric core reach normal operating temperature and realized that electric core keeps discharging under the normal atmospheric temperature environment all the time, promoted electric core discharge capacity and electric core life.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, a normal electric discharge structure of a battery cell in a low temperature environment includes a battery cell 10 and a heating patch 20 attached to the back of the battery cell, wherein a copper foil 210 is disposed in the heating patch, and the copper foil 210 is connected with a power supply and used for heating the battery cell.

The heating paste further comprises insulating rubber sheets 220 positioned on two sides of the copper foil, and the surface of the insulating rubber facing one side of the battery cell is provided with dotted glue 220 for adhering the heating paste to the battery cell 10.

The copper foil is continuously and uniformly bent between the two insulating rubber sheets, and power contacts 211 are formed at two ends of the copper foil.

The insulating rubber sheet 220 seals the copper foil 210 inside to ensure insulation with the outside and the cell contact surface, and is used for realizing adhesion of the heating paste and the cell 10 through the dot glue 230.

The top of the battery cell 10 is fixedly connected with a circuit protection board 102, and a protection circuit of the battery cell is arranged on the circuit protection board 102.

When this discharge structure applied, when being provided with the temperature-sensing piece with electric core week side and detecting that electric core 10 is in low temperature environment, release current gives heating subsides 20, and heating subsides 20 receives external current through power contact 211, through the internal resistance heat production of copper foil 210, on the heat transfer electric core 10 that will heat subsides 20 production through heat-conduction, electric core 10 temperature reached normal temperature. When the normal temperature is reached, the current is stopped to be supplied to the heating patch 20, and the copper foil on the heating patch 20 stops heating. If the temperature of the battery cell is reduced, the copper foil in the heating paste 20 is connected with the power supply again for heating, and the normal temperature of the battery cell 10 is repeatedly ensured.

In the second embodiment, the two sides of the heating paste are provided with bent buckling strips 101 buckled on the two sides of the battery cell, so that the back of the battery cell is tightly attached to the heating paste.

Any technical solution disclosed in the present invention is, unless otherwise stated, disclosed a numerical range if it is disclosed, and the disclosed numerical range is a preferred numerical range, and any person skilled in the art should understand that: the preferred ranges are merely those values which are obvious or representative of the technical effect which can be achieved. Because numerical value is more, can't be exhaustive, so the utility model discloses just disclose some numerical values with the illustration the technical scheme of the utility model to, the numerical value that the aforesaid was enumerated should not constitute right the utility model discloses create the restriction of protection scope.

If the terms "first," "second," etc. are used herein to define parts, those skilled in the art will recognize that: the terms "first" and "second" are used merely to distinguish one element from another in a descriptive sense and are not intended to have a special meaning unless otherwise stated.

Also, above-mentioned the utility model discloses if disclose or related to mutually fixed connection's spare part or structure, then, except that other the note, fixed connection can understand: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, the terms used in any aspect of the present disclosure as described above to indicate positional relationships or shapes include similar, analogous, or approximate states or shapes unless otherwise stated.

The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
