A comparison of the operating costs of EVs and ICEs

Here are some key factors:

1. Energy Costs: The cost per kilometer for electricity is typically lower than that for gasoline. In China, electricity prices range from about 0.5 to 1 RMB per kilowatt-hour (kWh), while fuel prices are much higher (around 7 to 9 RMB per liter). Assuming an EV consumes around 0.15-0.2 kWh per kilometer and a fuel vehicle consumes about 0.06-0.09 liters per kilometer, we can calculate the difference.

2. Maintenance Costs: EVs usually have lower maintenance costs because they have fewer mechanical parts and don’t require regular oil changes, spark plugs, exhaust systems, etc. Additionally, EVs often have regenerative braking systems, which reduce brake wear.

3. Government Subsidies and Incentives: In some regions, there are subsidies or tax incentives for purchasing and using EVs, which can further lower the overall cost.

Example Calculation:

Assuming an annual mileage of 15,000 kilometers, an electricity price of 0.8 RMB/kWh, and a fuel price of 7.5 RMB/liter:

• Electric Vehicle:

Electricity consumption per kilometer: 0.18 kWh
Cost per kilometer: 0.18 kWh × 0.8 RMB/kWh = 0.144 RMB
Annual electricity cost: 0.144 RMB × 15,000 km = 2,160 RMB

• Fuel Vehicle:

Fuel consumption per kilometer: 0.08 liters
Cost per kilometer: 0.08 liters × 7.5 RMB/liter = 0.6 RMB
Annual fuel cost: 0.6 RMB × 15,000 km = 9,000 RMB

• Annual Savings:

9,000 RMB (fuel cost) - 2,160 RMB (electricity cost) = 6,840 RMB

So, according to this calculation, an EV could save around 6,840 RMB per year compared to a fuel vehicle. This is a basic comparison of energy costs; actual savings could be more significant when considering the differences in maintenance costs and potential government subsidies.
