HEAT DISSIPATING BATTERY PACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18362750 titled 'HEAT DISSIPATING BATTERY PACK
Simplified Explanation
The abstract of this patent application describes a battery pack that includes a battery cell and an enclosure made of stainless steel. The enclosure has a first portion and a plurality of walls that form a body enclosing the battery cell. The enclosure also includes a layer of a second material, such as aluminum, copper, graphite, or graphene, which has a higher thermal conductivity than stainless steel.
- The patent application is about a battery pack design that includes a stainless steel enclosure with improved thermal conductivity.
- The enclosure consists of a first portion, a plurality of walls, and a second portion connected to the walls to enclose the battery cell.
- A layer of a second material, such as aluminum, copper, graphite, or graphene, is applied to at least a portion of the enclosure.
- The second material has a higher thermal conductivity than stainless steel, which helps in dissipating heat generated by the battery cell.
Potential applications of this technology:
- Electric vehicles: The improved thermal conductivity of the battery pack enclosure can help in efficiently managing the heat generated by the battery cells, enhancing the performance and lifespan of electric vehicle batteries.
- Portable electronics: Battery packs used in smartphones, laptops, and other portable devices can benefit from the improved thermal management provided by the stainless steel enclosure with a layer of high thermal conductivity material.
Problems solved by this technology:
- Heat dissipation: The use of a second material with higher thermal conductivity helps in dissipating heat generated by the battery cell, preventing overheating and potential damage to the battery pack.
- Improved battery performance: Efficient thermal management can enhance the overall performance and lifespan of the battery cells, ensuring optimal operation and reducing the risk of degradation.
Benefits of this technology:
- Enhanced safety: By effectively managing heat, the technology reduces the risk of thermal runaway and potential battery failures, improving the safety of battery packs.
- Extended battery life: The improved thermal management helps in maintaining the optimal operating temperature of the battery cells, which can extend their lifespan and overall battery pack longevity.
- Increased performance: By preventing overheating, the technology allows the battery cells to operate at their optimal temperature, resulting in improved performance and efficiency.
Original Abstract Submitted
Aspects of the disclosure involve various battery packs. In general, the battery pack includes a battery cell and an enclosure. The enclosure includes a first portion and a plurality of walls that extend perpendicularly from the first portion. The enclosure includes a second portion connected to the plurality of walls to form a body enclosing the battery cell. The first portion, the second portion, and the plurality of walls are a first material comprising stainless steel. The enclosure includes a layer of a second material covering at least a portion of at least one of the first portion, the second portion, and one of the plurality of walls. The second material comprises aluminum, an aluminum alloy, copper, a copper alloy, graphite, graphene, or a combination thereof and has a greater thermal conductivity than the first material.
