A report from the Department of Energy shows electric cars are less expensive to maintain and confirms similar reports.
“Electric and electrified powertrains have lower maintenance and repair costs than internal combustion engines (ICE) for all vehicle sizes in relation to the vehicle price,” said the DOE’s Argonne National Laboratory (PDF) in a report.
Pure electric vehicles or BEVs performed best.
The maintenance cost per mile reductions for HEVs, PHEVs and BEVs compared to ICEVs were 7%, 11% and 41%, respectively, the report said.
For example, BEVs for items like engine oil and transmission service did not have a cost due to the inherent difference in the powertrain.
(HEV refers to Hybrid Electric Vehicles, PHEV to Plug-In Hybrid Electric Vehicles, and BEV to Battery Electric Vehicles, also known as pure EVs.ICE refers to internal combustion engines or gas cars.)
Cars covered in the report include Tesla Model 3, Model S, Toyota Prius Prime, Chevy Volt and Bolt, Nissan Leaf, BMW i3, and VW Golf and e-Golf.
This reflects the results of consumer reports that show “big savings” for electric vehicles over traditional gasoline cars.
Hybrids had the lowest cost
Hybrid electric vehicles (think: Prius) had the lowest total cost per mile for 15 years in the small SUV category, beating BEVs, which were high due to the initial purchase price.
One result confirms a common problem in charging electric vehicles
Charging commercial electric cars can be costly due to the time it takes to charge an electric vehicle, the report said.
“Charging BEVs can be time consuming; Wage rates can make these costs dominate [Total Cost of Ownership] Total cost of ownership. “
And the added battery weight for commercial electric vehicles is (or becomes) an issue.
“Many vehicles would be affected by additional battery weight, which reduces the available payload capacity, and that cost can be significant.”
