According to energetic, Hyundai Mobis has developed a novel battery cell cooling compound to stop electric vehicle batteries from overheating.
The company seeks to acquire and commercialize this innovative battery cooling technology in order to become more competitive in the emerging mobility market.
Known as the “Pulsating Heat Pipe,” this material is placed in between battery cells to lower the internal temperature of the battery, which rises during rapid charging. It is composed of refrigerant and aluminum alloy. Even as battery heat generation grows, ultra-fast charging is expected to significantly reduce the time required to charge electric vehicles by implementing a dependable thermal management system that can withstand the heat.
High-heat-dissipation materials called heat pipes are used to cool electrical equipment like cellphones and computer CPUs. These are metal tubes that increase how well heat moves between two objects.
Specifically, even in high-speed moving cars, pulsating heat pipes distribute heat by internal refrigerant circulation and vibration, resulting in little performance reduction due to gravity. greater than 10 times the heat transport efficiency in comparison to the standard. Aluminum facilitates the rapid external transfer of heat from overheated battery cells.
To create battery systems (BSA), many battery modules (BMA) are usually combined with cooling fans, battery management systems (BMS), and other electronic devices. In BMA, a module-level component that directly generates electrical energy and has several battery cells stacked, battery cell overheating can be avoided by optimizing the cooling structure. Hyundai Mobis were successful in placing PHPs in between each battery cell. By quickly moving the heat generated in each cell to cooling blocks, they were able to stabilize the internal temperature at the module level.
Hyundai Mobis used press process technology to simplify the PHP manufacturing process and reduced production costs by allowing for large-scale continuous production during the manufacturing stage.
In order to facilitate mounting on car batteries, it also achieved PHPs with a thickness of only 0.8mm, which is significantly smaller and has a larger area than conventional heat pipes (about 6mm). Promoting the adoption of electric vehicles is the aim of this product quality enhancement.
