How the cost is worked out
- Battery capacity: MG MG4 64 kWh has a 61.7 kWh usable battery (SMMT/manufacturer data).
- Charge amount: 60% of battery = 61.7 × 0.6 = 37.0 kWh per session.
- Cost per session: 37.0 kWh × 26.11p/kWh = £9.67.
- Weekly: £9.67 × 7 sessions = £67.66.
- Annual: £67.66/week × 52 weeks = £3518.40.
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.
