BATTERY PACK HAVING HEAT DISSIPATING SYSTEM

摘要

A battery pack includes a phase change material, which implements temperature management of the battery pack by virtue of the heat dissipation action of the phase change material. The battery pack includes a plurality of battery cells, at least one of which is partially provided with a phase change material and brackets for supporting the plurality of battery cells. The phase change material is disposed at the maximum heat dissipating region of the battery cell, and the maximum heat dissipating region is a region partially extending from an intermediate position of the outer surface of the battery cell towards a positive pole end.
