EV Charging Time
Charging time depends on the charger type and battery size:
- Slow charger (2.3kW): 8-12 hours for a full charge
- Fast charger (7kW): 4-6 hours for a full charge
- Rapid charger (50kW): 30-60 minutes for 80% charge
- Ultra-rapid (150kW+): 15-30 minutes for 80% charge

EV vs Petrol/Diesel – Cost Comparison
Electric vehicles are typically much cheaper to run:
- Petrol car (45 MPG): ~16p per mile
- Diesel car (55 MPG): ~13p per mile
- Electric car (home charging): ~6p per mile
- Electric car (public charging): ~12p per mile
Electric cars can save you up to £1,000 per year compared to petrol, depending on your mileage and charging location.
