Problems solved by technology

[0003] However, many lithium battery packs today also have many problems. For example, the assembly of many lithium batteries together leads to the problem of heat dissipation of the battery pack. If a heat sink is added to the lithium battery pack, the arrangement of the lithium battery pack will be unstable in many cases. In addition, the performance of lithium batteries will drop a lot in the cold winter in the north, so the battery pack needs to be insulated, and the old battery pack does not have the function of heat preservation. At the same time, lithium batteries are charged and The discharge efficiency does not meet the needs of people in many cases, so we propose a lithium battery pack arrangement and fixing device

Embodiment 1

[0029] see Figure 1-4 , the upper shell 2 includes an upper connecting shell 21, the upper surface of the inner cavity of the upper connecting shell 21 is evenly and fixedly connected with an upper fixing column 22, and the inner cavity of the upper fixing column 22 is fixedly connected with a conductive coil 23, so The upper end of the conductor coil 23 is fixedly connected with the parallel conductor 5 .

[0030] Specifically, the conductive coil 23 is connected in parallel with the parallel wire 5, and the terminal 6 fixedly connected to the parallel wire 5 needs to be electrically connected to an external AC power source.

[0031] Specifically, the distance between the two adjacent upper fixing posts 22 from left to right is equal to the width of the fixing posts 22 .

[0032] Specifically, the lithium battery storage upper folder cavity 12 is formed between the front and rear two adjacent upper fixing columns 22 .

Embodiment 2

[0034] see Figure 5 , the lower shell 3 includes a lower connecting shell 31, the upper end of the lower connecting shell 31 is fixedly connected to the lower end of the upper connecting shell 21, and the upper end of the inner cavity of the lower connecting shell 31 is evenly and fixedly connected with a lower fixing column 32, so The inner cavity of the lower fixing column 32 is sleeved with a piston 33 , the upper end of the piston 33 is fixedly connected with a spring 34 , and the lower end of the lower fixing column 32 extends through the bottom surface of the lower connecting shell 31 to the water cavity 7 .

[0035] Specifically, the lower lithium battery storage cavity 13 is formed between the front and rear two adjacent lower fixing columns 32 , and the lower lithium battery storage cavity 13 and the upper lithium battery storage cavity 12 form a lithium battery storage cavity.

[0036] Specifically, the distance between the two adjacent lower fixing columns 32 from ...

Abstract

The invention discloses a vehicle-mounted lithium battery pack arranging and fixing device. The vehicle-mounted lithium battery pack arranging and fixing device comprises a shell, wherein the shell isformed by inserting and fixing an upper shell with a lower shell; the upper surface of the shell is fixedly connected with a connection cavity; an inner cavity of the connection cavity is fixedly connected with a parallel lead wire; the bottom surface of the shell is fixedly connected with a water cavity; an inner cavity of the water cavity is sleeved with a heat conduction plate; a cross-shapedsupport plate is integrally molded at the lower end of the water cavity; the middle part of the cross-shaped support plate is fixedly connected with an extrusion device. According to the vehicle-mounted lithium battery pack arranging and fixing device, upper fixed pillars and lower fixed pillars are matched and inserted with each other, so that the function of stably fixing lithium batteries is achieved; meanwhile, lead wire coils are placed in the upper fixed pillars; the lead wire coils can provide a battery pack internal magnetic field under the energized state, so that the charging and discharging efficiency of the battery pack can be improved; through cooperation of the lower fixed pillars and the water cavity in use, the function of adjusting the temperature is achieved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a device for arranging and fixing a vehicle-mounted lithium battery pack. Background technique [0002] Batteries have become an indispensable part of many electronic products. Lithium batteries for vehicles are power batteries for hybrid vehicles and electric vehicles. Because some technical properties of nickel-metal hydride batteries, such as energy density and charging and discharging speed, are close to To the theoretical limit, lithium batteries have the advantages of high energy density, large capacity, and no memory. [0003] However, many lithium battery packs today also have many problems. For example, the assembly of many lithium batteries together leads to the problem of heat dissipation of the battery pack. If a heat sink is added to the lithium battery pack, the arrangement of the lithium battery pack will be unstable in many cases. In addition, the perfo...
