David Bonnici  Gallery12 Petrol prices are all over the place at the moment. One minute they're at record lows, the next they're creeping back up to the same old prices that we've been accustomed to accept. It makes the idea of switching to electric power an interesting one - though how much would you be paying for each charge in comparison? Of course it all depends on the efficiency of the electric car and its conventionally powered equivalent or rival. 12 Petrol and diesel-powered cars are rated by how many litres of fuel they use per 100km (litres/100km). With electric vehicles it’s how many kilowatt hours (kWh) used per 100km. The lower the kWh/100km value, the less you’ll need to spend on household power to travel a given distance. With power also being priced per kWh, figuring out how much an electric car’s energy will cost is as simple as checking your electricity rate. MOREFuel Comparison: Diesel, petrol or LPG? For example, the Nissan Leaf consumes 10kWh/100km. If you’re paying 0.28c per kWh (an average price during peak periods within Victoria) it will cost you $2.80 (10kW x 0.28) to charge it enough to travel 100km. The Leaf has a claimed 400km range, which means a full charge will cost you $11.20 ($2.80 x 4). Advice EV Buyer's Guide: Electric Vehicles Under $65K Ranked – The Best and The RestWelcome to part one of three price-based EV buying guides, this one focused on the most affordable electric cars available in Australia today 2 days ago6 The Jaguar I-Pace on the other hand is rated at 19kWh/100km, which means it costs $5.32 for a 100km trip and $25.53 for a full charge to travel its claimed 480km range. Here’s a list of several EVs that are on the Australian market alongside similarly performing vehicles and how their energy costs compare based on manufacturer kWh/100km and litre/100km ratings. To keep things simple we based it on an assumed annual driving distance of 20,000km with electricity priced 0.28c per kWh, and fuel costing $1.60 for RON91 unleaded or $1.70 for RON95 premium unleaded (where specified). MORERising petrol prices spark calls for reduced retail margins and tax reductions These electricity numbers are based on current prices in Victoria, and will naturally vary depending on the energy market in your state. For example, electricity costs in South Australia are higher than the national average, while fuel costs are significantly lower than average.

Not quite. There are many other variables to consider, however, and we’ve done even more number-crunching to drill down into just how budget-friendly an electric shift would – or wouldn’t – be.

How much energy does an electric car use in kWh?And it's often challenging to charge an EV in the middle of the day when there is most likely to be excess PV generation. The average EV uses around 10 kWh/day.
How much electricity is needed to recharge an electric car?Generally, electric cars charged at home use about 7,200 watts (W) of electricity, which can vary depending on the mode and home charger. Most electric car chargers use between 32 and 40 amps, and connect to a 240 volt outlet in your home's breaker box.
How much power does an electric car use compared to a house?A typical U.S. home uses around 30 kilowatt-hours per day, depending on its size and which appliances people use. This means that a typical EV battery can store enough electric fuel to supply the total energy needs of a typical home for a couple of days.
