Title:
INTEGRATED CURRENT COLLECTOR FOR ELECTRIC VEHICLE BATTERY CELL
Document Type and Number:
WIPO Patent Application WO/2019/052425
Kind Code:
A1
Abstract:
Systems and methods to power an electric vehicle are provided. The system can include a battery pack having a plurality of battery modules, each of the battery modules can include a plurality of battery blocks. The battery blocks can include a plurality of cylindrical battery cells. An integrated current collector device can be formed in a single structure and coupled with the plurality of cylindrical battery cells. The integrated current collector device can include a first current collector to couple with positive terminals of the cylindrical battery cells at first ends of the cylindrical battery cells and a second current collector to couple with negative terminals of the cylindrical battery cells at the first ends of the cylindrical battery cells. An isolation layer can be disposed between the first current collector and the second current collector to electrically isolate the first current collector from the second current collector.
