Measuring conditions:

• Tested car: Nissan Leaf
  • Normal charge (Home Charging)
  • Eco-mode is ON.
  • Air conditioner is used in Winter and Summer.
• Electric power consumption: based on "Nissan Connect".
• Electricity cost per kWh: based on the agreement clause of the electric power company

The Monthly EV Charging Cost

EV charging cost is expressed by JPY (Japanese Yen)/km. The following figure shows the measured Monthly EV Charging Cost including consumption TAX, Renewable energy Levy and Fuel cost adjustment.

• The Renewable energy Levy is a part of the cost incurred by a power company to purchase renewable enegy power.
• The Fuel cost adjustment amount is the adjustment amount that fluctuates monthly depending on the average fuel price at that time calculated from the price of crude oil and LNG prices in trade statistics.

The EV monthly charging cost is around JPY4/km on average shown in the following figure.

In Winter and Summer, the Monthly EV Charging Cost increases due to the following reasons.

• The air conditioner is used.
• The Fuel cost adjustment amount is higher than that in Spring and Autumn.

EV is economical

The price of gasoline is about JPY180/litter in January 2025.

• The actual mileage of gas-powered vehicle is 10-15km/liter, resulting that the gasoline cost is JPY12-18/km.
• The actual mileage of HEV is 20-25km/liter, resulting that the gasoline cost is JPY9-7/km.

Hence, the monthly EV charging cost is less than half of the gasoline cost for gas-powered vehicle and also 2/3 of HEV.
