Power flexible packaging lithium-ion battery module

Abstract

The invention provides a power flexible package lithium ion battery module. The power soft-pack lithium-ion battery module includes: N module expansion frames, cell current-limiting balancer, soft-pack lithium-ion battery cells, three-sided tab connection strips, positive and negative terminals, module cover and fixed connectors; Among them, N is a positive integer; N module expansion frames, module covers and fixed connectors form the shell of the power flexible packaging lithium-ion battery module; the positive and negative terminals are set on the positive and negative electrodes of the power flexible packaging lithium-ion battery module ear output end; the lugs of the soft-packed lithium-ion batteries are connected to the three-sided lug connecting strips, and the cell current-limiting balancer is arranged on the three-sided lug connecting strips; thereby realizing rapid grouping of power lithium-ion batteries, and the present invention The provided power flexible packaging lithium-ion battery module is easy to maintain and safe and reliable.

Description

technical field [0001] The invention relates to a lithium-ion battery module, in particular to a power flexible package lithium-ion battery module. Background technique [0002] At present, the off-grid energy of automobiles is mainly fossil energy such as gasoline and diesel. 60% of the fossil energy is consumed by automobiles, and automobile exhaust pollutes the air environment. The birth of new clean energy is imminent. At present, the power lithium-ion battery can be used as an alternative energy source for automobiles. Due to the characteristics of lithium-ion batteries, lithium-ion batteries with steel shells, aluminum shells or PP hard shells generally have a safety hazard of explosion. [0003] In order to solve the safety hazards of hard-shell lithium-ion batteries, soft-pack lithium-ion batteries are proposed. The current series-parallel connection of power soft-pack lithium-ion batteries is usually riveted after the soft aluminum and nickel tabs are put on. Howe...

AI Technical Summary

Problems solved by technology

However, this connection method leads to high internal resistance of the lithium-ion battery and inconvenient maintenance. In addition, the soft tabs of the battery are easy to loosen and break during the long-term vibration of the car, which is unsafe. The outer box is filled with silica gel. Although silica gel can protect the battery, it will cause difficulties in the maintenance and heat dissipation of the battery pack, which will affect the performance of the battery.
