BATTERY MODULE HAVING COOLING STRUCTURE USING INSULATING OIL, AND BATTERY PACK AND VEHICLE COMPRISING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18029841 titled 'BATTERY MODULE HAVING COOLING STRUCTURE USING INSULATING OIL, AND BATTERY PACK AND VEHICLE COMPRISING SAME

Simplified Explanation

The abstract describes a battery module that includes a sub-module with a cell stack and cooling fins, front and rear bus bar frame assemblies, a housing, and front and rear sealing plates.

  • The battery module consists of a sub-module that contains multiple battery cells and cooling fins placed between the cells.
  • The sub-module is connected to a front bus bar frame assembly on one side and a rear bus bar frame assembly on the other side.
  • The housing of the battery module accommodates the sub-module.
  • The front sealing plate covers an opening on one side of the housing and has an inlet for insulating oil.
  • The rear sealing plate covers an opening on the other side of the housing and has an outlet for insulating oil.


Original Abstract Submitted

A battery module including: a sub-module, the sub-module including a cell stack including a plurality of battery cells and a plurality of cooling fins located between adjacent battery cells, a front bus bar frame assembly coupled to a first side of the cell stack in a longitudinal direction of the cell stack, and a rear bus bar frame assembly coupled to a second side of the cell stack in the longitudinal direction of the cell stack; a housing accommodating the sub-module; a front sealing plate covering an opening on a first side of the housing in a longitudinal direction of the housing and including an insulating oil inlet; and a rear sealing plate covering an opening on a second side of the housing in the longitudinal direction of the housing and including an insulating oil outlet.
