Five practical benefits of an EV
The benefits go beyond energy costs. Home charging, simpler servicing and quiet low-speed driving can also make day-to-day ownership easier.
Plug in at a dependable home, workplace or destination charger while the car is already sitting still.
Enjoy smooth acceleration, no gear changes and quiet progress, especially around town.
Follow the service schedule without engine-oil changes, spark plugs or an exhaust system.
1. EV energy can cost less per kilometre
Electric motors use energy efficiently, and home electricity is often cheaper per kilometre than petrol. The best case is dependable home charging on a suitable overnight tariff or from excess rooftop solar. Public fast charging is convenient, but it usually costs more than home charging.
The saving is not the same for everyone. Your car's energy use, electricity plan, petrol alternative and charging losses all matter. Use your own charging prices rather than relying on a general savings claim.
EV running costs: a worked 100 km energy example
Imagine an EV using 18 kWh/100 km and a petrol car using 7 L/100 km. These are ChooseEV examples, not Australian averages or promises for a particular model.
| Energy source | Example rate | Cost per 100 km |
|---|---|---|
| EV charged at home | 18 kWh × 30 c/kWh | $5.40 |
| EV at a public fast charger | 18 kWh × 60 c/kWh | $10.80 |
| Petrol car | 7 L × $1.90/L | $13.30 |
In this example, home charging saves $7.90 per 100 km compared with petrol. Public charging saves $2.50. Electricity drawn from the wall may also be higher than the car's stated consumption because charging loses some energy as heat. Purchase price, insurance, servicing, tyres, finance and resale are still missing, so this is an energy comparison—not total ownership cost.
2. The powertrain is simpler to maintain
A BEV has no engine oil, spark plugs, fuel system, exhaust or conventional multi-speed gearbox. Regenerative braking can also reduce wear on brake pads and discs. The Australian Government says the average overall EV maintenance bill is around 40% lower than for an equivalent petrol or diesel vehicle. That is an average, not a promise: service intervals and prices vary by model and brand. Compare written schedules and quotes for the exact cars on your shortlist, along with the manufacturer's local service and parts support.
Lower maintenance does not mean no maintenance. EVs still need scheduled inspections plus tyres, brakes, suspension, cabin filters and model-specific coolant or fluid work. Their extra weight and strong acceleration can increase tyre wear if the car is driven hard.
The main traction battery is not a routine replacement item, although its usable capacity can gradually reduce. Check the exact model's battery warranty, including its age, kilometre and capacity conditions. When buying used, ask for a battery health report where one is available.
3. Charging can happen while you do something else
With dependable charging where the car normally parks, you can plug in after arriving home or at work and leave with the charge you need. The car charges while you get on with your day, so you may need fewer separate trips to refuel.
This convenience depends on access. Apartment residents, renters and drivers who park on the street may need approval or a reliable workplace or public routine. Check whether charging fits somewhere you already park; a special weekly charging trip is less convenient than filling with petrol.
4. Driving is quiet, smooth and responsive
An electric motor responds immediately when you press the accelerator and does not pause for gear changes. At low speeds there is no engine vibration or exhaust noise, which can make traffic and suburban driving feel calmer. Tyre and wind noise are still present at higher speeds.
Many EVs can also pre-heat or cool the cabin from an app before departure. In an enclosed garage this avoids running a petrol engine to operate the climate control, though the feature and app access vary by model.
5. There are no tailpipe emissions
A BEV has no exhaust pipe, so it produces no tailpipe carbon dioxide or exhaust pollutants while driving. That matters most where people live, walk and breathe. The car and battery still take energy and materials to manufacture, tyres still create particles, and charging electricity can create emissions at the power station.
The environmental result therefore depends on the vehicle, how far it travels and the electricity used to charge it. Charging from renewable electricity reduces driving emissions further. Australia's Green Vehicle Guide lifecycle calculator lets you compare vehicles using local electricity-grid assumptions.
Useful extras—if the car includes them
Extra space
Some dedicated EV designs use a flat floor or front storage area, but packaging varies. Check the actual seats and cargo area.
Vehicle-to-load
Some models can power compatible appliances from the battery. Output, adapters and supported uses differ by model.
Remote features
Apps may control charging and cabin temperature. Confirm whether a subscription, mobile coverage or account transfer is required.
When the benefits may be smaller
- You cannot charge dependably: frequent public fast charging costs more and asks for more of your time.
- You drive very little: small annual energy savings may take a long time to offset a higher purchase price.
- Your regular job is unusually demanding: frequent towing, remote travel or very long days can narrow the suitable shortlist.
- The exact car costs more elsewhere: insurance, tyres, finance and depreciation can outweigh energy savings.

Common questions
Are electric cars cheaper to run than petrol cars?
They often are when charged at home, especially on a suitable overnight tariff or from excess rooftop solar. The saving shrinks when most charging happens at higher-priced public fast chargers. Compare your actual electricity rate, charging mix and the fuel use of a similar petrol car.
Do electric cars need less maintenance?
Usually. A BEV has fewer powertrain service items and regenerative braking can reduce brake wear. It still needs scheduled servicing, tyres, brakes, suspension, cabin filters and safety checks. Follow the exact manufacturer's schedule.
Do electric car batteries need replacing regularly?
No. The main traction battery is not a routine service item, but its usable capacity can gradually reduce. Check the battery warranty for the exact model, including its age, kilometre and capacity conditions. For a used EV, ask for a battery health report where available.
Are electric vehicles better for the environment?
A BEV has no tailpipe emissions. Manufacturing the car and battery, producing electricity and wearing tyres still have environmental impacts. The result improves when the EV replaces a less efficient vehicle, is kept for longer and is charged from a cleaner electricity supply.
What are the disadvantages of an electric car?
An EV can cost more to buy, takes longer to recharge than a petrol car takes to refuel, and is less convenient without dependable charging. Insurance, tyre costs, public-charging coverage and resale value vary. Start with the exact car and your routine, not a claim that all EVs are better at everything.
