PHEVs What are the disadvantages of PHEVs?
- Because they have both electric and gasoline components, PHEVs have a more complex design than BEVs.
- Maintenance is required on both systems. Gas engines require oil changes and the same checks that conventional gas engines need. And while the electric components (battery, electric motor, and electronics) require less maintenance than gas-powered engines, some is required.
- Having both a combustion engine and battery pack takes up space and adds weight.
