Abstract

The invention provides a soft-clad lithium battery module applied to an electric vehicle, the module comprises a soft-packed lithium battery, Side panel, foam, Heat sink, battery holder, Connecting tabs, bus tabs, fastening parts and other structures. The use of unique safety-type tabs improves electrical connection safety and reduces battery positioning accuracy requirements. The flexible busbarcan be bent freely to enlarge the use condition of the connecting piece, the module expansion can be realized relatively easily by using the modular bracket, the module structure is simplified by using the composite radiating plate, and so on, so that the soft-packaged lithium battery module has the advantages of compact structure, safety, stability, easy expansion and higher energy density.

Description

Technical field [0001] The invention relates to a soft-packed lithium battery module, in particular to a soft-packed lithium-ion battery module applied to the electric automobile industry. Background technique [0002] At present, the power of electric vehicles comes from lithium battery power battery packs. Because electric vehicles are more sensitive to space and endurance, they require higher requirements for the volume, quality, and energy of the power battery pack, that is, the power battery pack is required to have higher energy. As a type with higher energy density, soft pack lithium batteries are widely used in the electric vehicle industry. The inside of the power battery pack is composed of multiple modules in series and parallel, and the inside of the module is composed of batteries in series and parallel. The connection between modules is generally connected by a dedicated cable or bus. The space inside the module is narrow, and for the soft-packed battery cell, due...
