BATTERY PACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18588029 titled 'BATTERY PACK
The abstract describes a battery pack with cells, battery modules, a battery case, and a water jacket for cooling the battery modules.
- Cells have positive and negative terminals
- Cells are laminated in battery modules
- Battery case houses the battery modules
- Water jacket cools the battery modules from below
- First section of the battery case houses the battery modules and facilitates heat exchange with the water jacket
- Second section above the water jacket has no battery modules
- Gap between cells and inner wall of the battery case allows air to pass through
- Fin protrudes from the water jacket in the second section
- Fan circulates air across both sections
Potential Applications: - Electric vehicles - Energy storage systems - Portable electronic devices
Problems Solved: - Overheating of battery modules - Efficient cooling of battery cells - Space optimization in battery pack design
Benefits: - Improved battery performance and longevity - Enhanced safety by preventing overheating - Compact and efficient cooling system
Commercial Applications: Title: "Innovative Battery Cooling System for Electric Vehicles" This technology can be used in electric vehicles to improve battery performance and safety, potentially leading to increased market adoption and competitiveness in the electric vehicle industry.
Questions about the technology: 1. How does the water jacket cooling system compare to traditional air cooling methods? - The water jacket system provides more efficient and uniform cooling compared to air cooling, leading to better battery performance and longevity. 2. What impact does the gap between cells and the inner wall of the battery case have on cooling efficiency? - The gap allows for better airflow, enhancing the cooling process and preventing overheating of the battery cells.
Original Abstract Submitted
A battery pack includes cells having a positive terminal and a negative terminal, battery modules in which the cells are laminated, a battery case accommodating the battery modules, and a water jacket connected to a heat exchange system and configured to cool the battery modules from below. The battery case includes a first section in which the battery modules are arranged, and heat exchange between the battery modules and the water jacket is performed, a second section provided above the water jacket, and in which no battery module is disposed, a gap provided between the cells and an inner wall of the battery case, and through which air is capable of passing, a fin provided in the second section, and formed to protrude from a side of the water jacket, and a fan circulating air across the first section and the second section.
