How much does it cost to operate a gas engine, without figuring the cost of gas?

An interesting analysis. Ford has presented a comparison of the maintenance costs for the 2012 Focus petrol and EV models.1 They suggest that the life expectancy of the vehicle is 150,000 miles. They don't list any EV costs that are not already included in the costs of the Petrol version. The petrol version has the following additional costs:

•15 oil and filter changes at $29.95 each – $449.25

•Five air filter replacements at $24.95 each – $124.75

•Two cooling system flushes at $109 each – $218

•One transmission service – $179

•One drive belt replacement – $130

•One new set of spark plugs and installation – $69.95

For a total of $1170.95 This amounts to (1170.95/150,000 =) about $ .0078 which is close to your figure without the engine.

When you compare the change in price of electricity in the last year and the change in cost of gasoline you will find that an EV that uses .34 KW-hr / mile has an increased fueling cost of about $18 while a petrol vehicle that gets about 35 mpg has an increased fueling cost of over $350 using US national averages. There are two reasons for this difference. The electric vehicle is far more efficient and uses very little energy and the price differential in electricity is very small in any event.

One listing of the engine and transmission of a typical modern petrol engine gives a total of over 700 parts. (Engines require transmissions.) This is a reciprocating engine. A brushless electric motor might have only one moving part. You didn't determine the cost of a transmission replacement or work which may be more likely to fail than the engine. DC electric motors can be seen on conversion sites like KTA services priced at below $1500. A high performance water cooled electric motor might be purchased from a site like Metric mind for $3000 to more than $10,000. Mass production will allow the prices to fall but the warranty period for these electric parts may then also more closely follow their potential life. A motor that is not engineered for the load or one that overheats will tend to cook insulation and lead to premature failure. Bearings should last. Brushed motors might have some armature issues and brushes might have to be swapped out every 75000 to 100,000 miles. Electric is very simple and doesn't need a transmission. Electric motors can be reconditioned with new bearings and rewinding.

Very interesting and well presented. Since I know absolutely nothing about electric engines I have a question or two.

you calculate the replacement cost of a gas engine, however the vast majority of people do not replace their car's engine, they usually sell it or trade it in so instead of an additional cost there would be a reduction in cost.

What happens to the electric car's engine? Would it be replaced at the end of 200,000 miles?

Are you saying that both gas and electric cost 14 cents a mile? Is this a government standard?

One glaring fallacy is that electric costs are stable, they are regulated but they are not stable as oil cost rise so do electric costs. Also the cost of operating power plants and delivering power increases as inflation increases. And as demand outstrips production cost will be increased to provide for more plants. Also gas prices fluctuate while power cost increase but very very very very rarely decrease.

The sad thing is that the production of lithium batteries is very detrimental to the environment.

ddddd

Dunno.
