Survey results that EV has lower annual cost than own gasoline car already

According to a survey conducted in several countries including Japan, the result that the cost of owning an electric vehicle (EV) is lower than the conventional gasoline and diesel vehicles in total.

This survey was conducted by a research team by Kate Palmer of Leeds University et al. We estimated the cost of ownership for four years after purchasing a new car by dividing it into five types of EV, hybrid cars, plug-in hybrid cars, gasoline cars, and diesel cars, which are not hybrid types. EV has the lowest total cost The result that it becomes become clear has become clear. It is also clear that the trend was the same in all areas of Japan, the United Kingdom, and the United States (Texas, California) where the survey was conducted.

In the estimate, we investigate the cost, tax, maintenance cost, insurance cost, fuel cost and electricity fee divided by the vehicle price including subsidy, using the vehicle running from 10,000 km to 15,000 km a year as a model. As a result, Guardian compiled the per-year ownership cost revealed, the following graph shows that Pure Electric (complete EV) on the far left has the lowest cost. In the case of EV, the vehicle price (light blue) occupies a high proportion, but as a result that the total cost can be suppressed because the electricity bill (gray) is very cheap in addition to the small amount for the maintenance fee (yellow) It is getting.


Although gasoline cars and diesel cars are low in vehicle price, they are pushing up the total cost because they cost a lot of fuel cost (dark orange color). Also, in the graph, plug-in hybrid cars are the most expensive, but this is due to the subsidy system in the UK. In the case of the UK, subsidies to EV are the largest, and hybrid vehicles and plug-in hybrid cars receive only a small subsidy in comparison. As a result, the cost of plug-in hybrid vehicles with high vehicle prices generally increases. In Japan with different subsidy system, hybrid cars and plug-in hybrid cars will settle to the same level of cost.

The maintenance cost of EV and hybrid vehicles is low because the mechanism is simple because it does not have an internal combustion engine such as a gasoline engine and repair costs are low even if a failure occurs, and in addition to the point that surprisingly There seems to be a point that "the cost of replacing the brake pad is low". EV and hybrid cars that use "regenerative power generation" to use the motor as a generator during deceleration show the trial results that replacement costs are suppressed because there is less reduction in brake pads.

As of 2017, the EV to which a large amount of subsidies are paid is superior to the total, but in the future it will be possible to cut subsidies if the spread of EV advances, the merit will decrease Possibilities as well. However, it is also thought that the decrease in subsidy is almost canceled by EV, which the cost of the battery lifts the vehicle price, as the unit price of parts decreases due to mass production and the vehicle price falls ... apparently ...

In this survey, it is only surveyed about the financial cost and it is important to note that environmental factors such as carbon dioxide emissions are not included. In particular, the total balance of carbon dioxide emitted when producing a large amount of electric power and the environmental load when producing a large amount of lithium-ion batteries are completely different topics, and it is the first time that we consider these aspects in total It is important to understand that the real 'total cost of EV' will be ejected.

By the way, it seems that EV top 5 selling in the UK is as follows.

First place:Nissan Reef22,250 units
Second place:BMW · i 38800 units
3rd place:Tesla Model S6283 units
4th:Renault · Zoe6227 units (not yet released in Japan)
5th place:Nissan · e-NV 2002742 units
