Abstract
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.
Claims18
A battery pack for a cordless power tool, comprising:
- a plurality of battery cells wherein at least one battery cell of the plurality of battery cells is partially provided with a phase change material;
- and
- at least one bracket for supporting the plurality of battery cells;
- wherein the phase change material is disposed at the maximum heat dissipating region of the at least one battery cell and the maximum heat dissipating region is a region extending from an intermediate position of the outer surface of the at least one battery cell towards a positive pole end of the at least one battery cell.
A battery pack for a cordless power tool, comprising:
- a plurality of battery cells;
- a heat dissipating structure made of phase change material for dissipating heat from the plurality of battery cells, the heat dissipating structure being positioned solely on a predetermined region extending from an intermediate position of each battery cell towards pole ends of each battery cell wherein the predetermined region is a region of the battery cell with the largest heat generation and the quickest temperature rise;
- and
- at least one bracket for supporting the plurality of battery cells.
