BATTERY PACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18449274 titled 'BATTERY PACK
Simplified Explanation
The battery pack described in the patent application includes a tray with a bottom wall, a cell module containing at least one battery cell, a high voltage connection portion on the bottom surface of the cell module, a high voltage busbar connected to the connection portion, and a water absorbing sheet between the tray's bottom wall and the cell module's bottom surface. A first opening portion is located in the water absorbing sheet opposite the high voltage connection portion.
- Tray with bottom wall
- Cell module with at least one battery cell
- High voltage connection portion on cell module's bottom surface
- High voltage busbar connected to connection portion
- Water absorbing sheet between tray's bottom wall and cell module's bottom surface
- First opening portion in water absorbing sheet opposite high voltage connection portion
Potential Applications
The technology described in this patent application could be applied in electric vehicles, energy storage systems, and portable electronic devices.
Problems Solved
This technology helps prevent water damage to the battery pack components, particularly the high voltage connection portion, by using a water absorbing sheet.
Benefits
The use of a water absorbing sheet in the battery pack helps improve safety and reliability by reducing the risk of short circuits and other issues caused by water exposure.
Potential Commercial Applications
