Hyundai Mobis has developed an innovative battery cell cooling material designed to combat overheating during ultra-fast charging of electric vehicles (EVs). The company aims to commercialize this cutting-edge technology, enhancing its competitive edge in the evolving mobility market by offering a stable and efficient thermal management solution for EV batteries.
Key Highlights
- Pulsating Heat Pipe (PHP) Technology:
- Constructed from aluminum alloy and refrigerant, placed between battery cells.
- Significantly reduces battery overheating during ultra-fast charging.
- Promotes stable thermal management, minimizing performance degradation.
- Superior Heat Transfer Efficiency:
- PHPs offer over ten times the heat transfer performance of standard aluminum.
- Effectively dissipates heat from battery cells to the exterior through vibration and refrigerant circulation.
- Innovative Manufacturing:
- Streamlined press process allows for cost-efficient, large-scale production.
- Achieved ultra-thin PHPs (0.8 mm thick) for easy integration into EV batteries.
- Enhanced EV Charging Performance:
- Stable temperature control reduces charging times and improves battery lifespan.
- Supports broader adoption of electric vehicles with improved reliability and safety.
The PHP technology represents a significant advancement in thermal management systems. By incorporating heat pipes between individual battery cells, Hyundai Mobis efficiently transfers heat to cooling blocks, ensuring consistent temperature regulation across the battery module. This innovation addresses a critical need in modern EV systems, where overheating during rapid charging can impact performance and safety.
Additionally, the new manufacturing process simplifies PHP production while reducing costs. Hyundai Mobis’ ultra-thin design enables seamless installation in vehicle batteries, enhancing product quality and contributing to the increased adoption of electric vehicles.
