Problems solved by technology

[0003] When it is necessary to assemble a plurality of lithium batteries, it is necessary to arrange them according to the combined size of each lithium battery pack. However, when lithium batteries are combined, it is inconvenient to separate the lithium battery packs that need to be combined, resulting in too many lithium batteries. The groups are closely grouped together, so that the emitted heat source is not easy to discharge and concentrate, causing damage to the lithium battery itself. At the same time, when the lithium battery is installed, the installation space for the lithium battery is small and the installation is difficult; when the lithium battery After the combination, the density of the lithium battery will be increased due to the connection and placement of the combined structure, which will have a great impact on the subsequent heat dissipation and cooling work, reduce the normal performance of the heat dissipation function of the device, and reduce the thermal conductivity of the lithium battery and the heat source. Distributed effect; when the device is combined, it is not conducive to fixing the structure of the combination, which makes the subsequent disassembly and maintenance of the device inconvenient, and reduces the convenience of the device combination work

Embodiment 1

[0034] Example 1, such as Figure 1-3 As shown, during the installation of the lithium battery, the fixing of the fixing pin 11 and the pin hole 10 can be cancelled, and then the protective baffle 8 can be unfolded with the cooperation of the hinge block 7, so as to provide the operator with a space for operating the seat 6 , to increase the operability and convenience of the lithium battery pack during assembly.

Embodiment 2

[0035] Example 2, such as Figure 1-3 As shown, when encountering a lithium battery pack whose model and size do not match, the slidable guide block 802 moves in position under the cooperation of the guide rail 801, so that the guide block 802 drives the connecting seat 803 and the partition plate 804 to move, and the separation plate 804 needs to be separated. The position of the lithium battery pack is adjusted, and the installed lithium battery pack is insulated and bonded through the insulating bonding layer 805. This not only increases the flexibility during the assembly of the lithium battery, but also separates the lithium battery pack to reduce the use of the lithium battery. The tightness of the structure enhances the implementation effect of the subsequent heat dissipation structure.

[0036] Working principle: When the device is in use, the base plate A1 and the base plate B5 can be spliced ​​and combined through the butt fitting of the splicing column 901 and the i...

Abstract

The invention discloses a combined lithium battery device which comprises a substrate A, a substrate B and a controller, placing seats are arranged at the bottoms of the inner sides of the substrate Aand the substrate B, fitting plates are arranged on the sides, close to each other, of the two ends of the inner sides of the substrate A and the substrate B, and top covers are arranged at the topsof the two sets of fitting plates. The sides, away from each other, of the two sets of attaching plates are provided with heat conduction silicone grease. Through movable unfolding of a hinge blocks and a protective baffle, the unfolding space and angle of the base plate A or the base plate B can be enlarged when the lithium battery is installed, the operability and convenience of lithium batteryinstallation by workers are improved, layered adjustment can be conducted according to the sizes of different lithium battery combinations under mutual cooperation of the positioning separation assemblies, the difficulty coefficient of subsequent heat dissipation work is prevented from being increased due to the fact that excessive lithium batteries are attached and concentrated together, and theworking efficiency and protectiveness of lithium battery combination and assembly are improved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a combined lithium battery device. Background technique [0002] At present, most electric vehicles use lithium battery devices to provide power to the vehicle. In order to meet the continuation mileage and reduce the charging frequency, each electric vehicle needs to install multiple lithium battery boxes, and each lithium battery box is arranged with multiple rows of lithium batteries. Module, each lithium battery module is formed by stacking multiple lithium battery cells neatly to form a combined lithium battery pack; [0003] When it is necessary to assemble a plurality of lithium batteries, it is necessary to arrange them according to the combined size of each lithium battery pack. However, when lithium batteries are combined, it is inconvenient to separate the lithium battery packs that need to be combined, resulting in too many lithium batteries. The groups are...
