Abstract

The invention provides a flexibly packaged battery module, and relates to the technical field of a battery module. The flexibly packaged battery module comprises at least two flexibly packaged batteries; each flexibly packaged battery comprises a flexibly packaged cell; the exterior of the flexibly packaged cell is coated with a cell insulating layer; positive and negative tabs are arranged on theflexibly packaged cell; openings are formed in positions, corresponding to the positive and negative tabs, of the cell insulating layer; and the flexibly packaged batteries are electrically connectedthrough the positive and negative tabs. By coating the exterior of each single flexibly packaged cell with the cell insulating layer, the flexibly packaged cells are isolated; and meanwhile, a conductive material generated in explosion of the single flexibly packaged battery is coated in the cell insulating layer, so that explosion of the single flexibly packaged battery to other flexibly packaged batteries can be prevented, thereby preventing chain explosion after thermal runaway.

Description

technical field [0001] The invention relates to the technical field of battery modules, in particular to a soft pack battery module. Background technique [0002] With the production and consumption of conventional fossil energy approaching its peak and gradually becoming exhausted, the ensuing environmental pollution has become increasingly prominent, and an energy system dominated by renewable energy is gradually taking shape. With the current global auto industry facing huge challenges of energy and environmental issues, an international consensus has been reached on the development of new energy electric vehicles and the promotion of the strategic transformation of the traditional auto industry. Judging from the trend of energy conservation and emission reduction in the automotive industry, my country's development of energy-saving and new energy vehicles is an inevitable choice for the advancement of automotive technology and industrial upgrading. [0003] The power ba...
