Abstract
The present disclosure relates to a battery module, including a cell assembly including one or more battery cells and a busbar assembly electrically connecting the one or more battery cells, a module case including an opening part at least partially opened on one surface, and forming an accommodating space for accommodating the cell assembly therein through the opening part, a module cover coupled to the module case to close the opening part, and a filling part which is provided between an outside of the busbar assembly and the module case and includes an electrically insulating material, and an assembly method thereof.
Claims20
A battery module comprising:
- a cell assembly comprising one or more battery cells and a busbar assembly electrically connecting the one or more battery cells;
- a module case comprising an opening part at least partially opened on one surface, and forming an accommodating space for accommodating the cell assembly therein through the opening part;
- a module cover coupled to the module case to close the opening part;
- and
- a filling part which is provided between an outside of the busbar assembly and the module case and comprises an electrically insulating material.
A battery module comprising:
- a cell assembly comprising one or more battery cells and a busbar assembly electrically connecting the one or more battery cells;
- a module case comprising an opening part at least partially opened on one surface, and forming an accommodating space therein to accommodate the cell assembly through the opening part;
- and
- a module cover coupled to the module case to close the opening part,
- wherein the accommodating space comprises:
- a filling space which is located between the busbar assembly and the module case and in which a filling part formed of an electrically insulating material is located;
- and
- a cell accommodating space in which the cell assembly is located.
An assembly method of a battery module comprising a cell assembly comprising one or more battery cells and a busbar assembly electrically connecting the one or more battery cells;
- and a module case forming an accommodating space for accommodating the cell assembly therein together with a module cover, the assembly method comprising:
- disposing a heat dissipation part on a bottom surface of the accommodating space;
- positioning the cell assembly in the accommodating space through an opening part in which at least a portion of one surface of the module case is opened;
- inserting or injecting a filling part comprising an electrically insulating material provided between an outside of the busbar assembly and the module case;
- and
- coupling the module cover to the module case to close the opening part.
