Applications
Self-Regulating Heating Films Electric Vehicles Applications
Battery Thermal Management
- Problem: Cold batteries = reduced efficiency, slower charging, accelerated degradation.
- Solution:
- Preheating: Bring cells to 15–25°C before charging/driving.
- Active Balancing: Maintain uniform temperature across modules.
Charging Infrastructure
- Problem: Frozen charging ports and cables delay operations.
- Solution:
- Flexible Heating Pads: Anti-icing for connectors, cables, and stations.
- Self-Powered: Integrates with solar-powered charging points.
Fleet & Commercial EVs
- Problem: Delivery delays due to cold-weather battery failures.
- Solution:
- Low-Voltage Safety: 12/24V compatibility for trucks and buses.
- Remote Monitoring: IoT-enabled temperature tracking.
