Problems solved by technology

[0003] At present, in the field of new energy electric vehicles, the cooling methods of the power battery pack system mainly include natural cooling, air cooling and liquid cooling. The heat dissipation of the bottom surface of the group or one of the other surfaces, for the liquid-cooled heat dissipation on the surface of each battery cell, the heat dissipation effect is the best, but the cost is high, the space utilization rate is poor, and the reliability is poor
The heat dissipation based on the bottom surface of the module or another surface is easy to implement and low in cost, and the space utilization rate is relatively high, but the heat dissipation effect is relatively poor

Abstract

The invention relates to a battery pack tab cooling structure, a battery pack and a vehicle with the battery pack. The battery pack tab cooling structure comprises a tab connecting element, an insulation heat conduction block and a liquid cooling plate, wherein the tab connecting element comprises a first support arm, a second support arm and a third support arm; the first support arm and the second support arm are electrically connected with two tabs of two adjacent battery cells of the battery pack; the insulation heat conduction block comprises a heat conduction component and an insulation component; the heat conduction component has an approximately rectangular cross section and comprises a first side surface, a second side surface, a top surface and a bottom surface; the insulation component surrounds the heat conduction component on the outer periphery position of the heat conduction component, so that at least a part of the first side surface, the second side surface and the top surface of the heat conduction component is exposed out; the lower surface of the liquid cooling plate is in direct or indirect heat conduction contact with the top surface of the heat conduction component; in addition, cooling liquid can flow through the liquid cooling plate so as to cool the heat conduction component; the first side surface and the second side surface of the heat conduction component form surface contact with the inner surface of the first support arm and the inner surface of the second support arm of the tab connecting element.

Description

technical field [0001] The present disclosure relates to a battery pack tab cooling structure, a battery pack having the battery pack tab cooling structure, and a vehicle having at least one of the battery packs. Background technique [0002] In today's world, vehicles have become an indispensable means of transportation for people's work and life. With the shortage of oil resources, the improvement of environmental protection requirements and the development of technology, more and more vehicles are driven by using electric energy in whole or in part. more common. [0003] At present, in the field of new energy electric vehicles, the cooling methods of the power battery pack system mainly include natural cooling, air cooling and liquid cooling. The heat dissipation of the bottom surface of the group or one of the other surfaces, for the liquid cooling of the surface of each battery cell, has the best heat dissipation effect, but the cost is high, the space utilization rate...
