Method for producing battery modules or battery systems having a plurality of battery cells

摘要

A method for producing battery modules or battery systems having a plurality of battery cells includes interconnecting and optionally arranging the battery cells with cell connectors to form the battery module or battery system architecture. The method also includes fitting the battery module or battery system with terminals and packaging all the battery cells of the battery module or system in a common plastic sheath by injection molding, so that the battery cells and cell connectors of the battery module or system are surrounded substantially completely by the plastic sheath. The battery module terminals or battery system terminals remain accessible from outside. A battery module or battery system can be produced in accordance with the method of the disclosure.

主权项

1. A method for producing battery modules or battery systems having a plurality of battery cells, comprising:
interconnecting battery cells of the plurality of battery cells with cell connectors to form one of a battery module architecture and a battery system architecture; fitting terminals to one of the battery module and the battery system; and packaging all of the battery cells in a common plastic sheath by encapsulating injection-molding, so that the battery cells and cell connectors are surrounded substantially completely by the plastic sheath, while the terminals remain accessible from outside the plastic sheath, wherein the plastic sheath formed by encapsulating injection molding comprises a plastic material and a filler admixed into the plastic material, the filler including at least one of boron nitride (BN), aluminum nitride (AIN), aluminum oxide (Al2O3) and beryllium oxide (BeO), and wherein at least one of the battery cells is individually enclosed by at least one of individually sealing with plastic, individually welding in film and individually surrounding by Al foil before interconnecting with cell connectors.
