Setting a New Standard for Safety, Efficiency, and Faster Charging in Electric Vehicles
Global automotive technology leader Hyundai Mobis has unveiled its latest innovation to tackle one of the most pressing challenges in electric vehicles (EVs): battery overheating during ultra-fast charging. The company’s Pulsating Heat Pipe (PHP) technology is designed to enhance battery cooling, boost safety, and reduce charging times, paving the way for greater EV adoption worldwide.
The Breakthrough: Pulsating Heat Pipe (PHP) Technology
1. How It Works
- Constructed from aluminium alloy and refrigerant, the PHP system is placed between EV battery cells to efficiently transfer heat.
- Utilizes the vibration and circulation of refrigerant within ultra-thin tubes to disperse heat.
- Offers 10x better heat transfer efficiency compared to standard aluminium cooling plates.
2. Advanced Features
- Ultra-Thin Design: At only 0.8mm thick, PHPs are significantly slimmer than traditional heat pipes (6mm), optimizing space efficiency.
- High Stability: Designed to maintain performance regardless of vehicle motion or vibration, ensuring consistent cooling in all conditions.
Key Benefits for EV Performance and Safety
- Superior Thermal Management
- PHPs stabilize internal temperatures during rapid charging, preventing battery overheating.
- Enables safer charging cycles, reducing risks of thermal incidents.
- Faster Charging Times
- By managing heat effectively, PHP technology supports ultra-fast charging, cutting down the time needed to power up EV batteries.
- By managing heat effectively, PHP technology supports ultra-fast charging, cutting down the time needed to power up EV batteries.
- Cost-Effective Manufacturing
