At Ion Lab, we specialise in developing advanced thermal management solutions for energy storage systems. In collaboration with Modul System, we designed and built a battery heater system specifically for extreme cold weather applications.
The Challenge
Lithium-ion batteries struggle to perform efficiently in extreme cold. At temperatures below 0°C, charging can cause irreversible damage to battery cells, significantly reducing their lifespan and effectiveness. For applications in sub-zero environments, it was crucial to develop a system that could warm the battery to a safe operating temperature before charging.
Our Solution
Ion Lab developed a thermal management system that integrates heating elements directly into the battery assembly. These elements gradually warm the cells from -30°C to 0°C, ensuring the battery reaches a safe temperature before charging begins.
This system was carefully designed to provide:
- Uniform Heating – The heating elements are strategically placed to distribute heat evenly across all cells, preventing thermal imbalances.
- Energy Efficiency – The system uses minimal power while effectively raising the battery temperature to the required level.
- Seamless Integration – Designed to work in tandem with the battery management system, the heater automatically activates when needed.
Real-World Testing
To validate its effectiveness, the system underwent rigorous testing in both controlled and real-world environments. In a cold climate chamber, it successfully warmed battery cells from -30°C to 0°C, proving its reliability under extreme conditions. Further testing in real-world applications confirmed its ability to maintain battery performance in freezing temperatures.
This project demonstrates Ion Lab’s expertise in developing practical solutions for challenging environments. By combining innovative engineering with real-world testing, we continue to push the boundaries of energy storage technology, ensuring reliable performance even in the harshest conditions.
