// Home vs Public

Home charging (Level 2) costs R2-3.50/kWh. Public DC fast charging can cost R5-10/kWh. Charging at home overnight is almost always cheapest.

// Charge to 80%

Charging from 80-100% is much slower due to battery protection. Most EV owners charge to 80% for daily use, saving time and extending battery life.

// vs Petrol

At R2.80/kWh, an EV costs ~R0.45/km. A petrol car at 8L/100km and R24/L costs ~R1.92/km. That's a 75% saving on fuel alone.

// Solar Charging

If you have solar panels, charging during the day can be essentially free. A 5kW solar system can fully charge an EV battery in a day at zero marginal cost.
