The cost of charging an EV will largely depend on your location and the battery capacity of the EV. To give an example, the average price for electricity in Australia is about $0.25 per kilo Watt-hour. You’ll need about 18kWh to travel for 100 km in your EV, which equates to around $4.50.
It’s also worth noting that the price changes between peak and off-peak electricity rates.
Traditional vehicles require about 11 litres of fuel to travel 100 km, which is about $16.65 if you’re paying $1.50 per litre. Even the most efficient diesel engine can only manage 5 litres to reach 100 km, which equates to about $7.50. So across the board, EVs are much cheaper to run than traditional vehicles
