Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a positive and negative insulating side plate of a liquid-cooled battery module. Background Art

[0002] A battery module is a unit composed of multiple batteries or battery cell assemblies connected together. Compared with a single battery or battery cell assembly, it can provide higher voltage and capacity. At the same time, a protective shell and an insulating assembly are set around the connected battery or battery cell assembly, and an insulating side plate is set at the end. The insulating side plate can provide protection and insulation for the battery module while multiple battery modules can be connected and assembled through wires to form a larger battery pack with strong flexibility and good safety.

[0003] The Chinese patent number CN202111588763.9 discloses a battery module insulating end cover, an end cover assembly, and a battery module, wherein the battery module insulating end cover includes an insulating end plate and an insulating cover plate which are separately arranged, an output terminal fixing seat which passes through the output terminal channel of the metal end plate is provided on the insulating end plate, a hollow which is adapted to the output terminal fixing seat is formed in the middle of the insulating cover plate, the insulating cover plate covers the metal end plate around the output terminal channel, and the minimum space distance between the outer edge of the insulating cover plate and the output terminal is not less than the safe electrical clearance from the output terminal to the metal end plate. The insulating end plate and the insulating cover plate which are separately arranged are adopted, and the insulating cover plate covers the metal end plate around the output terminal channel, so that the peripheral connection part of the output terminal channel of the metal end plate is sandwiched in the interval between the first side wall of the metal end plate and the insulating end plate, and the width of the peripheral connection part of the output terminal channel does not need to be reduced, and the safe creepage distance of the output terminal can be met by setting the width of the insulating cover plate.

[0004] Although the above patent can solve the corresponding technical problems, there are still certain defects: the existing insulating end cover is inserted into the segment fixing seat. When connecting multiple battery modules, the surface area of ​​the insulating end cover is small, and then when installing the connected metal end plate, the operating space and area are small, which makes the installation difficult. At the same time, in order to adapt to the shape of the surface of the insulating end cover so that the metal end plate does not protrude too much, the area and shape of the metal end plate are consistent with the insulating end cover, which leads to a smaller connection position area. When the battery module is working, the heat generated cannot be fully dissipated, affecting the safety of use. Utility Model Content

[0005] The utility model aims to provide a liquid-cooled battery module positive and negative electrode insulating side plate with a large installation and operation space and good heat dissipation effect in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a liquid-cooled battery module positive and negative insulating side plate, including an end plate and an insulating cover plate inserted and detachably arranged on the end plate, the upper surface of the end plate is formed with a slot adapted to the insulating cover plate, the insulating cover plate includes an insert plate inserted into the slot and a contact plate arranged on the insert plate, the contact plate is located on the side of the end plate and is parallel to the side of the end plate, when the output terminal is connected, the output terminal connection end is made to fit with the surface of the contact plate and installed parallel to the end plate.

[0007] A further improvement is that: the plug board is also provided with a fixing protrusion with the same width as the slot.

[0008] A further improvement is that an anti-slip boss is provided on the edge of the contact plate.

[0009] A further improvement is that an insulating isolation plate is also provided on the back of the end plate.

[0010] A further improvement is that the insulating isolation board is a flat plate structure made of bakelite material.

[0011] A further improvement is that an isolation flat plate body extends outwardly from the top edge of the anti-slip boss.

[0012] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when the output terminal connection end is installed, the contact plate is parallel to the end plate, and then the output terminal connection end can be fixedly installed in a direction parallel to the end plate. While keeping the length of the battery module fixed, the contact plate can be lengthened to make the operation construction plane larger and more convenient for connection and installation. At the same time, a larger output terminal connection end can be placed on the contact plate, thereby making the output terminal connection end in contact with the air larger, so that the heat dissipation effect during the conduction process is better, and the safety of use is guaranteed.
