How the cost is worked out
- Battery capacity: Tesla Model 3 Standard Range has a 57.5 kWh usable battery (SMMT/manufacturer data).
- Charge amount: 60% of battery = 57.5 × 0.6 = 34.5 kWh per session.
- Cost per session: 34.5 kWh × 26.11p/kWh = £9.01.
- Weekly: £9.01 × 7 sessions = £63.06.
- Annual: £63.06/week × 52 weeks = £3278.89.
Note: assumes 100% charging efficiency. Real chargers typically have ~10% loss, so actual electricity drawn from the grid is slightly higher. Rapid public charging costs are set by commercial operators and are not subject to Ofgem cap.
