How Long Does It Take to Charge an Electric Car?
From 30 minutes at a fast charger to over a day on a powerpoint: the simple formula behind EV charging times, with worked examples for a 60kWh battery.
Most electric cars charge from 10 to 80 per cent in 30 to 60 minutes at a DC fast charger. At home on a 7kW wallbox, a typical 60kWh battery takes about 8.5 hours from empty to full, or about 5 hours for a 20 to 80 per cent top-up. On a standard powerpoint, expect more than 24 hours for a full charge. The underlying maths is simple: energy needed in kWh divided by charging power in kW equals hours.
What’s the quick formula?
Divide the energy you need by the power of the charger:
Charging time (hours) = energy needed (kWh) ÷ charger power (kW)
Say your 60kWh battery is at 30 per cent and you want 80 per cent. That’s half the battery, or 30kWh. On a 7kW wallbox: 30 ÷ 7 = about 4.3 hours. On a 50kW fast charger: 30 ÷ 50 = about 36 minutes.
Two real-world adjustments: charging is slightly lossy (add roughly 10 per cent on AC), and DC charging tapers as the battery fills, so fast-charger sessions run longer than the raw division suggests, especially past 80 per cent.
How long does each charger type take?
Worked examples for a typical 60kWh battery:
| Charger type | Typical power | 10 to 80% (42kWh) | Empty to full |
|---|---|---|---|
| Standard powerpoint (10A portable charger) | 2.3kW | ~18 hours | ~26 hours |
| Home wallbox, single-phase | 7kW | ~6 hours | ~8.5 hours |
| Home wallbox, three-phase | 11 to 22kW | ~2 to 4 hours | ~3 to 5.5 hours |
| DC fast charger | 50kW | ~50 minutes | Not recommended |
| DC ultra-rapid charger | 150 to 350kW | ~15 to 40 minutes | Not recommended |
Three caveats on that table. AC charging (the first three rows) is capped by your car’s onboard charger, commonly 7kW or 11kW, so a 22kW wallbox won’t help a car that maxes out at 11kW. DC times depend heavily on the individual car’s peak rate and how well it holds it. And “not recommended” reflects how slow and battery-unfriendly DC charging from 80 to 100 per cent is; networks often charge idle fees for lingering.
Why does charging slow down after 80 per cent?
Lithium batteries accept charge quickly when partly empty and slowly when nearly full. Your car’s battery management system tapers the rate as it fills to protect long-term battery health, the same way a phone slows near 100 per cent. On a DC fast charger, the run from 80 to 100 per cent can take as long as the run from 10 to 80 did.
That’s why manufacturers quote 10-to-80 times, and why experienced road-trippers charge to 80 per cent and drive on. It’s faster overall to make two short stops than to sit through one long taper.
What actually limits your charging speed?
The slowest link in the chain wins:
- Your car’s maximum DC rate. This is the big one. Some older or cheaper EVs cap at 50kW, many mid-range cars sit between 100 and 150kW, and 800-volt cars can exceed 200kW. Plugging a 50kW-limited car into a 350kW charger doesn’t make it charge faster.
- Your car’s onboard AC charger. Usually 7kW or 11kW. This caps wallbox and destination charging regardless of the unit’s rating.
- Battery temperature. Cold batteries charge slowly. Many EVs precondition the battery when you navigate to a fast charger; use that feature in winter.
- State of charge. Arriving at 10 per cent charges much faster than arriving at 60.
- Shared power. Some charging sites split power between adjacent bays when both are in use.
What’s the smartest way to charge day to day?
Most owners barely think about charging time, because the car charges while they sleep. The average Australian car covers around 35km a day, which even a humble powerpoint can replace overnight. A 7kW wallbox gives you a comfortable buffer and lets you exploit cheap overnight windows; our home charging guide compares the options, and the cost guide shows why overnight charging is also the cheapest.
Save DC fast charging for road trips. Plan stops around 10-to-80 sessions of 20 to 45 minutes, roughly aligned with a coffee or a meal break, and you’ll rarely feel like you’re waiting. Our guide to public charging in Australia covers where the fast networks are and how to use them.
One last reframe that helps new EV owners: stop thinking in “time to full” and start thinking in “range added per hour”. A 7kW wallbox adds roughly 35 to 40km of range per hour, a 50kW charger about 300km per hour, and an ultra-rapid session can add 300km in under half an hour for cars that support it. For the overwhelming majority of days, you need far less than you think.
Frequently asked questions
How long does it take to charge an electric car at a fast charger?
Most EVs charge from 10 to 80 per cent in 30 to 60 minutes on a 50kW DC fast charger, and in 15 to 40 minutes on a 150kW-plus ultra-rapid charger, depending on the car's maximum charging rate. The last 20 per cent is much slower, which is why most drivers stop at 80.
How long does it take to charge an EV at home?
On a 7kW wallbox, a typical 60kWh battery takes about 8.5 hours from empty to full, or around 5 hours for a 20 to 80 per cent top-up. On a standard powerpoint with a portable charger at 2.3kW, a full charge takes more than 24 hours, though overnight is plenty for daily commuting.
Why do electric cars charge slower after 80 per cent?
The car deliberately tapers the charging rate as the battery fills to protect its long-term health, the same way a phone slows near full. Going from 80 to 100 per cent on a DC charger can take as long as 10 to 80 did, so on road trips it's faster to charge to 80 and move on.
Does a 350kW charger charge every car faster?
No. Your car can only charge as fast as its own maximum DC rate, which might be 50kW, 100kW or 200kW-plus depending on the model. A car limited to 100kW charges at the same speed on a 350kW charger as on a 100kW one.
