Problems solved by technology

However, when the heat generated by a cell unit in the pouch battery module is higher than the heat dissipated by it and the heat continues to accumulate, if there is no effective control countermeasure, there will be a high risk of thermal runaway, and even lead to the failure of the pouch power battery module. explosion accident
Usually thermal runaway spreads very quickly among the battery cells in the soft-pack power battery module, which brings serious safety risks to the occupants of the vehicle. Big

Abstract

The invention provides a soft package power battery module and a system thereof. The module comprises a housing; a plurality of heat insulation pieces arranged in the housing at intervals, wherein thehousing is internally divided into a plurality of independent cavities by the heat insulation pieces; a soft package battery pack arranged in the housing, wherein the soft package battery pack comprises a plurality of battery core units which are electrically connected with one another, the battery core units being distributed in the different cavities; and a plurality of pressure relief parts arranged on the housing, wherein the plurality of pressure relief parts correspond to the plurality of cavities, and the pressure relief parts are used for releasing high-temperature substances in the corresponding cavities. The embodiment of the invention provides the soft package power battery module with good safety performance and the system thereof.

Description

technical field [0001] The present application relates to the field of power batteries, in particular to a soft pack power battery module and its system. Background technique [0002] The soft pack power battery module can be installed on the vehicle to provide an energy source for the vehicle. [0003] A general pouch power battery module includes a plurality of electrically connected battery cells. The pouch power battery module will generate heat during operation. When the heat can be dissipated in time, the soft pack power battery module can be used safely. However, when the heat generated by a cell unit in the pouch battery module is higher than the heat dissipated by it and the heat continues to accumulate, if there is no effective control countermeasure, there will be a high risk of thermal runaway, and even lead to the failure of the pouch power battery module. Explosion accident. Usually thermal runaway spreads very quickly among the battery cells in the soft-pa...
