🔋 Key Features of New EV Battery Efficiency Standards
The new UK standards focus on multiple performance and sustainability metrics:
✔️ 1. Energy Efficiency Rating
Manufacturers must now provide standardized energy consumption data (kWh per 100 miles).
✔️ 2. Battery Durability Requirements
Batteries must retain a minimum percentage of capacity after a certain number of cycles (e.g., 70–80% after 8 years).
✔️ 3. Fast Charging Efficiency
Standards now measure how efficiently batteries accept high-speed charging without excessive degradation.
✔️ 4. Thermal Management Performance
Better heat management systems are required to improve safety and longevity.
✔️ 5. Recycling and Sustainability Metrics
Manufacturers must disclose recycling rates and use of sustainable materials.
