Problems solved by technology

[0003] However, due to the complex structural design of the liquid cooling system of the battery pack and the large number of pipelines and interface components, when the car works under complex working conditions for a long time, when there is a bump, it is easy to cause the inside of the battery pack to loosen, causing safety hazards. The structural design of the battery pack is unreasonable, and the problem of heat dissipation affects the life and use of the battery pack

Abstract

The invention discloses a battery pack with a stable structure. The battery pack comprises a battery shell, a first heat dissipation partition plate, a first battery module, a fixed frame, a second battery module and a second heat dissipation partition plate. The battery pack is characterized in that the first heat dissipation partition plate, the first battery module, the fixed frame, the secondbattery module and the second heat dissipation partition plate are sequentially installed in the battery shell from top to bottom; the shell comprises a shell cover and a bottom shell; the shell coveris matched with the bottom shell; an air inlet is formed in the side wall of one end of the bottom shell; and an air outlet is formed in the side wall of the other corresponding end of the bottom shell. The battery pack provided by the invention is simple in structural design and high in compactness; and buffer springs on the first heat dissipation partition plate and the second heat dissipationpartition plate can guarantee that devices in the battery pack are not loosened inside due to external jolting and shaking, and meanwhile, the internal stability and normal heat dissipation of the battery pack can be ensured with accommodation in the battery pack not affected.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a structurally stable battery pack. Background technique [0002] The performance, life and safety of new energy vehicle power batteries have a great influence on the heat generated by the battery module of the battery pack. In recent years, as new energy vehicles have higher requirements for high-power charging and discharging performance and environmental adaptability Looking for an effective and reliable battery pack thermal management system has become the focus of current work. There are four commonly used cooling methods for power battery packs: natural cooling, air cooling, liquid cooling, and refrigerant direct cooling. Among them, the liquid cooling system is widely used by mainstream car companies at home and abroad due to its high cooling efficiency. [0003] However, because the structural design of the liquid cooling system of the battery pack is relatively compli...
