Abstract
A battery module includes a housing, at least one cell stack inside the housing, a tightening assembly and a thermal conductive element. The tightening assembly includes first and second plugin members. The first plugin member has a first stopping portion and a first bolt portion connected with the first stopping portion, and the first bolt portion is tapered from the first stopping portion. The second plugin member has a second stopping portion and a second bolt portion connected with the second stopping portion, and the second bolt portion is tapered from the second stopping portion. The first and second plugin members are detachably inserted into the battery module from two opposing sides of the cell stack. The thermal conductive element tightens the cell stack to the housing.
Claims14
A battery module, comprising:
- a housing;
- at least one cell stack, disposed inside the housing;
- a tightening assembly, including:
- a first plugin member, having a first stopping portion and a first bolt portion connected with the first stopping portion, the first bolt portion being extended in a tapering manner away from the first stopping portion;
- and
- a second plugin member, having a second stopping portion and a second bolt portion connected with the second stopping portion, the second bolt portion being extended in the tapering manner away from the second stopping portion;
- wherein the first plugin member and the second plugin member are individually and detachably inserted into the battery module from two opposing sides of the at least one cell stack, and a second surface of the at least one cell stack, opposite the first surface, is tightened to the housing;
- and
- a thermal conductive element, disposed on the second surface, tightening the second surface of the at least one cell stack to the housing.
A battery module, comprising:
- a housing;
- at least one cell stack, disposed inside the housing;
- a stuff-insert element, disposed in a gap formed between a first surface of the at least one cell stack and the housing, wherein a second surface of the at least one cell stack, opposite the first surface of the at least one cell stacks, is tightened to the housing;
- and
- a thermal conductive element, disposed on the second surface, tightening the second surface of the at least one cell stack to the housing through the stuff-insert element;
- wherein the stuff-insert element is made of a rigid material and applies force to the first surface to tighten the second surface to the housing;
- and
- wherein the stuff-insert element includes a middle rigid portion and two thermal conductive layers laminated individually to two opposing sides of the middle rigid portion.
A battery module, comprising:
- a housing;
- a plurality of cell stacks, disposed inside the housing;
- a stuff-insert element, disposed in a gap formed between the plurality of cell stacks, wherein a second surface of the plurality of cell stacks, opposite a first surface of the plurality of cell stacks, is tightened to the housing;
- and
- a thermal conductive element, disposed on the second surface, tightening the second surface of the plurality of cell stacks to the housing through the thermal conductive element;
- wherein the stuff-insert element is made of a rigid material and applies force to the first surface to tighten the second surface to the housing;
- and
- wherein the stuff-insert element includes a middle rigid portion and two thermal conductive layers laminated individually to two opposing sides of the middle rigid portion.
