What is the actual cost of electricity for electric vehicles? In-depth report on the case of home charging

As electric vehicles (EVs) become increasingly popular, many people are concerned about the actual operating costs, especially electricity costs.
In this issue.Porsche's Taikan 4S Cross Turismo and Tesla's Model 3 Highland Long RangeThis report describes the actual cost of electricity for home charging for our family, which owns two EVs.

In conclusion, feel free to ride these two high-performance EVs as much as you want,Only 13,178 yenThe result was a surprise.
Let's take a closer look at just how staggering this amount is.

It's not for one car; it's for the electricity for two EVs.

Home charging environment and power contracts

First, let me describe our home charging environment.
Parking.Two regular household 200V outlets installedThe system is designed to be used for the following purposes. Each outlet has a capacity of 3 kW, one each for Taikan and Model 3.
In this environment, the two units are charged almost daily.

The power contract is with Kansai Electric Power Co.eSmart 10."The company uses a plan called This plan is characterized by very low nighttime electricity rates. Specifically, the rate structure is as follows:

Night time (10 p.m. to 8 a.m. the next morning): 15.53 yen/kWh
Daytime (1:00 p.m. to 4:00 p.m.): 38.53 yen/kWh
Living time (8:00 a.m. to 10:00 p.m.): 30.11 yen/kWh (summer)

The case of our family,Charging is done almost 991 TP3T night time.Therefore, the cheapest rate is 15.53 yen/kWh.

Amazing electricity bill: breakdown of 13,178 yen/month

The period we are reporting on is approximately one month, from August 26, 2024 to September 24, 2024. Electricity usage and rates for this period were as follows:

Total amount used: 600 kWh
Breakdown: night time 591 kWh, living time (summer) 9 kWh
Amount billed: 13,178 yen

Some of you may be surprised by these results.
Only 13,178 yen to run two EVsThe reason for this is that the price of a gasoline car is the same as the price of a gasoline car. Consider how inexpensive this is compared to a gasoline-powered car.

At the gas station near my house, the price of gasoline is currently about 170 to 180 yen/liter. If you own two cars, you may need to refuel twice a week.

Compared to this, the amount of 13,178 yen per month is astoundingly low. Moreover, this is the amount that is being moved,Porsche Taikan and Tesla Model 3, high-performance cars with very high driving quality.It is.

The True Value of Electric Vehicles: Combining Performance and Economy

It is important to emphasize that we are not arguing merely that they are cheaper. Certainly, some would argue that eco-cars and light cars are more fuel-efficient. However, if we start making such arguments, we would end up saying, "Why don't you just ride a moped?

I would argue that,You can move a high-performance, fun-to-drive car like the Taikan or Model 3 for this amount of money.This is the value of being a "good" car. For example, the Taikan has power and ride quality comparable to the Panamera V8 class. I used to drive a Panamera Turbo, but its fuel economy was about 3 to 4 km/L for a little driving in the city, and 8 to 9 km/L for commuting. This meant that I had to refuel every week, which cost me at least 20,000 to 30,000 yen per month.

In comparison, the fact that a Taikan and a Model 3 can be moved for a combined price of $13,178 is a remarkable economy. Moreover, for this amount of money, the following mileage is achieved:

Taicang: 600-800 km/month
Model 3: 1,000 to 1,500 km/month (by the way, the car ran 1,241 km this time)

13,178 yen for such a long distance is justCombines performance and economy.I would say it is evidence.

especially,For those who drive short distances around town, the advantages of EVs are more pronouncedSince EVs do not have the concept of idling, they are extremely energy efficient when stuck in traffic. They consume only air conditioning and audio during stop-and-go traffic, which is a significant advantage over gasoline-powered vehicles.

EVs are an ideal option for people whose lifestyles involve short-distance travel, such as picking up and dropping off children or traveling to and from train stations.

It is important to note, however, that this case is the result of an environment in which home charging is available. If you do not have charging facilities at home and use only outside charging stations, there is a strong possibility that this amount will not be enough to cover the cost. Nevertheless, it would still be more economical than a gasoline-powered car.
EVs are cheaper to operate when compared to gasoline-powered vehicles of the same performanceThis is almost certainly true. In fact, EVs are more economical in many cases, even if they do not have the same performance.

Set to be 80% by 8:00 AM.

Finally, we would like to touch on the general perception of EVs in Japan.

Unfortunately, a negative image of EVs tends to prevail in Japan. This may be due to various factors. Positive news may be difficult to spread due to adult circumstances, or feelings of envy and jealousy among those who cannot afford EVs may be influential.

Results,Negative opinions, articles, and videos on EV tend to gain more access. Therefore, positive information like this one is difficult to spreadCurrent situation.

However, when one actually owns and operates an EV, the benefits of being able to move it economically in this way become clear.High performance and low running costI am convinced that this is the true value and appeal of EVs.

I hope that accurate information about EVs and actual experiences of using them will be shared more widely. If so, more people will understand the true value of EVs and consider them as a new option for car selection.
