BATTERY PACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240322291 titled 'BATTERY PACK
The abstract describes a patent application for a battery pack that includes cells with positive and negative terminals, battery modules where the cells are laminated, a battery case to hold the modules, and a water jacket connected to a heat exchange system to cool the modules from below. The battery case has a first section for the modules, a second section above the water jacket with no modules, a gap for air circulation between the cells and the case's inner wall, fins protruding from the water jacket, and a fan to circulate air across the sections.
- Cells with positive and negative terminals
- Battery modules where cells are laminated
- Battery case to hold modules
