๐Ÿ“š Key Facts: EV & PHEV Economics & Road User Charge Policy

How does PHEV charging and petrol hybrid operation work?
Plug-in Hybrids (PHEVs) are charged at home using solar or off-peak electricity for everyday city commuting (e.g. 50% of annual km). For longer highway trips, they seamlessly switch to their onboard petrol hybrid engine (consuming roughly 5.0 L/100km). Because PHEVs charge at home, they don't require expensive DC Superchargers.
Why does home solar charging make driving almost free?
When you charge during daylight hours from rooftop solar, your marginal energy cost is 0ยข to 8ยข/kWh. At 15.5 kWh/100km, 100 km of driving costs $0.00 to $1.24 โ€” compared to $16.00+ for a petrol car.
What is the proposed Road User Charge (RUC)?
Australian treasuries proposed replacing petrol fuel excise with a distance charge: 3.095 ยข/km for pure BEVs and 2.476 ยข/km for PHEVs. Even with RUC fully added, electric and plug-in hybrid driving remains significantly cheaper than petrol.
