Description
Technical Field
The utility model belongs to the technical field of lithium ion battery test equipment and specifically relates to, relate to a can improve battery anchor clamps of low temperature discharge energy.
Background
At present, lithium ion batteries have been widely used in the fields of digital products, electric vehicles and energy storage, in particular square aluminum-shell batteries and soft aluminum-plastic batteries, because of their advantages of high energy density, good cycle performance, greenness and no pollution. But the discharge performance at low temperature is not satisfactory due to the influence of the material.
In order to ensure interface contact and simulate the actual use environment in a module, a clamp is mostly adopted for clamping test in the prior art; the clamps are mostly metal plates. In the actual test process, the battery has certain temperature rise due to chemical reaction, the discharging capacity at low temperature can be slightly improved, but the heat absorption capacity of the metal clamping plate is strong, and the energy increase at low temperature caused by the temperature rise effect of the battery is inhibited.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to use a heat loss that anchor clamps can reduce metal splint and bring, help the battery to exert the actual effect of charge-discharge under the low temperature.
To achieve the purpose, the utility model adopts the following technical proposal:
a battery clamp capable of improving low-temperature discharge energy comprises a metal upper clamp plate and a metal lower clamp plate, and is characterized in that an upper insulating and heat-insulating layer is fixed on the lower surface of the metal upper clamp plate, a lower insulating and heat-insulating layer is fixed on the upper surface of the metal lower clamp plate, the thickness of the insulating and heat-insulating layer is 1-5mm, and the thickness of the metal clamp is 5-15 mm.
The metal fixture is made of aluminum alloy or steel.
The insulating layer is made of silica gel, asbestos, aerogel pads or foamed plastic.
The utility model has the advantages that the temperature rise of the battery can be kept during the low temperature test, and the discharge energy is improved; meanwhile, the insulating inner layer can avoid short circuit risk caused by contact of the battery and the metal clamp.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the specific embodiments with reference to the drawings.
For the existing square aluminum-shell battery, as shown in fig. 1, an upper insulating and heat-insulating layer 2 is fixed on the lower surface of a metal upper splint 1, and a lower insulating and heat-insulating layer 4 is fixed on the upper surface of a metal lower splint 3, wherein the insulating and heat-insulating layer can be silica gel, asbestos, aerogel cushion or foamed plastic.
When in use, the battery is clamped by the screws with the same force around; the whole battery is completely covered by the metal clamping plate and the insulating layer. As shown in fig. 1, the thickness of the battery is 33.2mm, the thickness of the battery clamp plate is 15mm, and the thickness of the aerogel is 5 mm.
The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and any changes or transformations that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
