Split mounting type soft package lithium ion battery module based on water-cooling heat dissipation

Abstract

The invention discloses a split mounting type soft package lithium ion battery module based on water-cooling heat dissipation, which comprises a steel belt. Two sets of pulling plates are arranged at the two ends of the steel belt in an attached mode respectively, a plurality of sets of soft package lithium batteries are installed between the two sets of pulling plates in an inserted mode, a heat conduction pad, a battery support and a heat conduction plate are arranged between every two adjacent soft package lithium batteries in an attached mode, and two sets of first connecting pieces are arranged at the tops of the soft package lithium batteries; a second connecting piece is arranged at the top of the battery support, and water cooling plates are connected to the two sides of the pulling plates at the two ends, the soft package lithium battery, the heat conduction pad, the battery bracket and the heat conduction plate respectively. Stable clamping can be achieved, the structural strength of the battery module is kept, the heat conduction pad, the battery support and the heat conduction plate are arranged, the battery module has the advantages of insulation, flame retardance, light weight and convenience in installation and maintenance, and heat is transmitted to the water cooling plate through the heat conduction pad and the heat conduction plate to be dissipated.

Description

Technical field [0001] The present invention belongs to the technical field of battery energy storage, and more particularly to a assembled soft bag lithium ion battery module based on water-cooled heat dissipation. Background technique [0002] Since the energy storage is plays an important role in the adjustment of new energy grid-connected power generation, the industry is very optimistic about the prospects of the new energy and online storage market. The energy storage technology is moving towards large capacity, high conversion rates, and low cost applications. The energy storage technology can largely solve the randomness and volatility issues of new energy power generation, allowing it to have the characteristics of the conventional power supply, achieving predictable, controlling, and schedulable of intermittent renewable energy power generation. [0003] Different types of large-capacity grid energy storage technologies are distributed, losing, equipped, equipped with a...

Problems solved by technology

[0005] For example, the authorized announcement number is a lithium-ion battery disclosed by CN111613753A, although it solves the problem of local lithium analysis caused by the abnormal pressure in the lithium-ion battery due to side reactions, thereby improving the cycle performance of the lithium-ion battery and prolonging the life of the lithium-ion battery. However, it does not solve the problems that the existing soft-pack lithium-ion batteries cannot achieve stable fixed support, cannot effectively realize water cooling and heat dissipation, and the structure is not simple enough, light, and inconvenient to install and fix. We propose an assembled soft-pack lithium-ion battery module based on water cooling
