How Long Does It Really Take to Charge an EV at Home?
It is the question almost every new EV owner asks first, and the honest answer is: it depends, but probably less than you think. "How long to charge" is the wrong frame for home charging. The better question is how much range you add each night, and for most drivers, the car is full long before morning.
Think in Range Added Per Hour, Not Total Hours
Charging from empty to full sounds slow, but it almost never happens at home, because the battery rarely runs to empty. What matters is how much range goes back in per hour. A common 7kW home charger adds roughly 40 to 50 kilometres of range for every hour it runs. Plug in for eight or nine hours overnight and that is several hundred kilometres returned, far more than a typical day's driving uses.
How Much Do You Actually Drive?
The average car covers a few dozen kilometres a day. If a day's driving removes, say, 50 kilometres of range, a 7kW charger replaces that in around an hour. The car then sits plugged in and full for the rest of the night. Seen this way, home charging is less like refuelling and more like charging a phone, topped up while you sleep, ready each morning.
What Changes the Speed
Three things set the pace: the charger's output, the home's supply, and the car's onboard charger. A 7kW single-phase unit suits most homes; three-phase can be faster if the car accepts it. Battery size matters for a full charge, a larger battery takes longer end to end, but again, the daily top-up is what counts, not the rare empty-to-full.
The Wall-Socket Comparison
Charging from an ordinary power point with the portable cable adds only around 10 to 15 kilometres of range per hour, fine as an occasional backup, but it can struggle to keep up with regular driving. A dedicated charger is several times faster, which is the whole reason home chargers exist.
Topping Up Beats Filling Up
The mental shift that makes home charging click is to stop thinking about full charges. A petrol car runs near empty then fills completely; an EV charged at home is topped up a little every night, so it lives most of its life comfortably charged and rarely sees a low battery. That is why "hours to full" is the wrong measure, what matters is that each night replaces the day, which a home charger does with ease.
Where Public Fast Charging Fits
For the occasional long trip that exceeds the battery's range, public rapid chargers fill the gap, adding a large chunk of range in well under an hour because they deliver DC power directly. The everyday pattern for most Central Coast drivers is the reverse of a petrol routine: charge slowly at home most of the time, and use fast public charging only now and then on longer journeys. Home handles the daily driving; public handles the road trip.
It also helps to set the charger's limit sensibly. Many cars and chargers let you cap the daily charge level for everyday use and only fill to 100% before a long trip, which is gentler on the battery over time. None of this changes the headline point: with a dedicated home charger, the car spends each night topping up quietly and is ready every morning, whatever your daily distance.
A useful rule of thumb when planning: work out roughly how far the car travels on a normal day, then check how long the charger takes to put that range back. For most households the answer is an hour or two of charging for a full day's driving, a fraction of the time the car sits in the driveway overnight. Once that clicks, charging anxiety tends to disappear, because the maths shows the home charger has hours of headroom every single night, even allowing for the occasional bigger day.
Frequently Asked Questions
How much range does a home charger add per hour?
A typical 7kW charger adds roughly 40 to 50 kilometres of range per hour, depending on the vehicle. Over a normal overnight charge that is several hundred kilometres, well beyond most days' driving.
Do I need to charge from empty every time?
No. Most drivers top up from wherever the battery sits at the end of the day, which is usually well above empty. The car simply replaces the day's driving overnight and sits full until morning.
Is a wall socket fast enough?
It adds only around 10 to 15 kilometres of range per hour, so it works as a backup but can fall behind regular driving. A dedicated charger is several times quicker and is the better setup for daily use.
Will a bigger battery take much longer?
For a full empty-to-full charge, yes, there is more to fill. But the daily top-up that replaces a day's driving is short regardless, because you are only adding back what you used.
