How Long Does It Take to Charge an Electric Car? (2026)
Short answer: how long it takes to charge an electric car depends mainly on the charger. On a high-power DC fast charger, the popular models in this guide go from 10% to 80% in roughly 18 to 38 minutes. On a 7 kW home wallbox a typical full charge takes 6–8 hours, and on a 3 kW household socket around 12 hours, according to BYD's UK charging guide. Your car's own power limits, the battery's temperature and how full it already is can stretch or shorten those times.
This guide covers the three charging levels, a simple formula to estimate charging time yourself, real figures for six popular EVs, why charging slows down after 80%, what home charger installation involves, and how Oman's new public charging fees work from October 2026.
Key takeaways
- DC fast charging: 10–80% in about 18 minutes for the Hyundai Ioniq 5 and Porsche Taycan on high-power chargers, and about 24–38 minutes for the Tesla Model 3 RWD and BYD Atto 3.
- Home charging: a 7 kW wallbox typically needs 6–8 hours for a full charge, so an overnight session covers most daily needs.
- The formula: hours ≈ kWh you need to add ÷ charging power in kW, using whichever is lower, the charger's power or the car's limit.
- The 80% rule: charging power tapers as the battery fills, which is why fast-charging times are quoted to 80%.
- Oman from 1 October 2026: public charging is priced by charger power, from 50 baisa per kWh on chargers up to 90 kW to 120 baisa on chargers of 181 kW and above.
How long does it take to charge an electric car by charger type?
Charging speed is set by power, measured in kilowatts (kW). The US Department of Energy's Alternative Fuels Data Center (AFDC) groups chargers into three levels:
| Charging level | Supply | Power | Range added (AFDC estimate) |
|---|---|---|---|
| Level 1 | 120 V AC | About 1.9 kW | About 5 miles (8 km) per hour |
| Level 2 | 208/240 V AC | 2.9–19.2 kW (home units typically 7.2 kW) | About 25 miles (40 km) per hour |
| DC fast charging | Direct current | Up to 500 kW | About 100–200+ miles (160–320+ km) per 30 minutes |
"Up to 500 kW" describes the most powerful chargers, not what every car can accept. The car decides how much of the available power it takes, which is why two EVs plugged into the same charger can finish at very different times.
Single-phase vs three-phase in 230-volt markets
Level 1 and Level 2 are North American terms based on 120- and 240-volt supplies. In 230-volt markets, home charging is usually described by power and by the type of supply instead. The Energy Saving Trust reports that a single-phase connection supports up to about 7.4 kW, while 22 kW charging needs a three-phase supply. That is why 7 kW is treated as the practical maximum on a single-phase home supply in the UK.
The simple formula for electric car charging time
You can estimate electric car charging time with one division. BYD's UK charging guide puts it simply: hours = battery energy to add (kWh) ÷ charging power (kW). BYD's own rule-of-thumb figures look like this:
- 3 kW (household socket): around 12 hours
- 7 kW (home wallbox): 6–8 hours
- 22 kW (three-phase AC): around 3 hours
- 50 kW (DC): 80% in around 40 minutes
- 350 kW (DC): 80% in around 20 minutes
Two corrections make the formula realistic. First, use the power your car can actually accept, not just the number on the charger: when the charger offers more than the car's limit, the car's limit is what counts. Second, you rarely charge from empty. As an illustration, adding 35 kWh on a 7 kW wallbox takes about 35 ÷ 7 = 5 hours. On DC fast chargers the average power over a session is lower than the peak, because charging slows as the battery fills.
Electric car charging time by model
The table below gathers manufacturer and independent figures for six popular EVs. Check the charge window before comparing: a 10–80% time and a 30–80% time are not comparable, because the 30–80% session adds 20 percentage points less energy.
| Model | Peak DC charging power | DC charging time | Charge window | Source |
|---|---|---|---|---|
| Hyundai Ioniq 5 (800 V) | 350 kW charger | 18 minutes | 10–80% | Hyundai |
| Hyundai Ioniq 6 | 350 kW charger | 18 minutes | 10–80% | Hyundai (reported) |
| Porsche Taycan (2024) | 320 kW | About 18 minutes | 10–80% | Porsche |
| Tesla Model 3 RWD (LFP) | 175 kW | About 24 minutes | 10–80% | EV-Database |
| BYD Atto 3 | 88 kW | As little as 29 minutes / 38 minutes | 30–80% / 10–80% | BYD UK / EV-Database |
| BYD Seal (82.5 kWh) | 150 kW | 26 minutes | 30–80% | BYD |
A few details behind those numbers:
- Hyundai Ioniq 5: according to Hyundai, 15 minutes on a 350 kW charger adds up to 336 km of range with the 84 kWh battery, or 270 km with the 63 kWh battery. On a 50 kW charger Hyundai quotes 1 hour 16 minutes (84 kWh) or 58 minutes (63 kWh), and a full AC charge on a European three-phase supply takes 7 hours 35 minutes or 5 hours 50 minutes. The Ioniq 6 is reported at up to 351 km added in 15 minutes.
- Porsche Taycan: Porsche raised the 2024 Taycan's peak charging power from 270 kW to 320 kW, and says the car can hold more than 300 kW for up to five minutes. On 400-volt chargers limited to 150 kW, Porsche puts the session at about 33 minutes.
- Tesla Model 3: Tesla's website quotes Supercharging at up to 250 kW and up to 195 miles (about 314 km) added in 15 minutes for the Long Range RWD. The Rear-Wheel Drive with an LFP battery peaks at 175 kW and accepts up to 11 kW on AC, according to EV-Database. See our Tesla Model 3 page for model-specific service.
- BYD Atto 3: BYD UK lists 88 kW peak DC power and 30–80% in as little as 29 minutes. EV-Database, measuring 10–80%, gives 38 minutes, plus 11 kW AC charging and 6 hours 30 minutes for a full AC charge. Our BYD Atto 3 page covers servicing for this model.
- BYD Seal: BYD quotes 150 kW DC charging and 30–80% in 26 minutes for the 82.5 kWh version.
What changes charging time: the factors that matter
1. The car's onboard charger limit
On AC charging, power passes through the car's onboard charger, and that component sets a ceiling. A car limited to 11 kW gains nothing from a 22 kW wallbox; it still charges at 11 kW. Check your car's AC limit before paying for a more powerful home unit.
2. Charger power versus the car's maximum
On DC, the lower of the two numbers wins. Hyundai's Ioniq 5 figures show how much it matters: 18 minutes for 10–80% on a 350 kW charger, against 1 hour 16 minutes on a 50 kW charger for the 84 kWh car. In the other direction, a Model 3 RWD that peaks at 175 kW will not charge any faster on a 350 kW charger.
3. The charging curve: why EV charging slows down after 80%
Fast charging is not a flat line. Power is highest when the battery is low and tapers as it fills, with charging explainers commonly placing the slowdown at around 70–80%. That is why manufacturers quote DC times to 80%, and why on a road trip it is often quicker to charge to 80% and move on than to wait for 100%. The Taycan shows the shape clearly: it can hold more than 300 kW, but only for up to five minutes of the session.
4. Battery temperature and preconditioning
Charging speed also depends on battery temperature, which is why many EVs precondition the pack before a fast-charging stop. Tesla's Model 3 owner's manual explains that the car preconditions its battery when you navigate to a Supercharger or selected third-party fast chargers. Skipping that step can mean a slower session. EVS offers battery health and thermal management checks for the systems that keep the pack at the right temperature.
5. Heat
Drivers in hot climates often ask whether heat slows charging. The best-known recent heat data is actually about range, not charging time: Recurrent's study of 29,716 EVs, published in June 2025, found about 5% range loss at 32°C, rising to 17–18% at around 37–38°C. Separately, Geotab has reported that DC fast charging in heat accelerates battery wear. Parking in shade, letting the car precondition and avoiding repeated fast charges on a heat-soaked battery are sensible habits in the Gulf.
BYD megawatt charging: is 5-minute charging real?
The most dramatic charging claims come from BYD in China. In March 2025, BYD unveiled its Super e-Platform, which it says runs at 1,000 volts and 1,000 amps for 1,000 kW of charging power, with a 10C charge rate and 400 km of range added in 5 minutes (BYD). It launched on the Han L and Tang L in China, where BYD said it planned more than 4,000 megawatt charging stations.
Treat these as manufacturer claims. Electrek reported in December 2025 on an owner's video showing a 746 kW peak and 10–70% in 4 minutes 40 seconds, but that was not an independent test. For the cars most people drive today, charging time is still set by the power limits in the table above.
How long to charge an electric car at home, and what installation involves
At home, speed matters less because the car is usually parked for hours. With BYD's rule of thumb of 6–8 hours for a full charge on a 7 kW unit, an overnight session is normally enough to start the day with a full battery.
The AFDC's home charging guidance sets out the basics for the US: Level 2 charging needs a 240-volt circuit, the work should be done by a certified electrician, permits may be required, and installations follow Article 625 of the National Electrical Code. Rules differ by country. In Dubai, for example, installing a charger reportedly requires DEWA approval and a DEWA-approved contractor under its EV Charging Infrastructure Regulation (version 1.2, July 2025). Check your own utility's requirements before buying hardware.
Two practical points apply everywhere: match the wallbox to your car's onboard charger limit rather than buying the most powerful unit available, and confirm whether your supply is single-phase or three-phase before considering 22 kW. EVS offers EV charger installation for owners who want it done properly.
Charging an electric car in Oman: public charging fees from October 2026
Charging time works the same way in Oman as anywhere else, but from 1 October 2026 the charger you choose also changes what you pay. Muscat Daily reports that the Ministry of Transport, Communications and Information Technology (MTCIT) has set public charging fees by charger power:
| Charger power | Fee from 1 October 2026 | What it means for charging time |
|---|---|---|
| Up to 90 kW | 50 baisa per kWh | Enough for cars with a low DC peak, such as the BYD Atto 3 at 88 kW |
| 91–180 kW | 90 baisa per kWh | Covers the peak of the Model 3 RWD (175 kW) and BYD Seal (150 kW) |
| 181 kW and above | 120 baisa per kWh | Only faster for cars that accept high power, such as the Ioniq 5 and Taycan |
The takeaway: a higher-tier charger only saves time if your car can use the extra power. An Atto 3 peaks at 88 kW, so a charger above 90 kW will not charge it faster but will cost more per kWh under the new tiers. Planning a long drive? Read our Muscat to Salalah EV guide before you set off.
Frequently asked questions
How long does it take to charge an electric car at home?
On a 7 kW home wallbox, a typical full charge takes 6–8 hours, and on a 3 kW household socket about 12 hours, according to BYD's UK guide. Most drivers plug in with some charge left, so a normal overnight top-up is shorter. For your own car, divide the kWh you need by the lower of the charger's power and the car's AC limit.
How long does a Tesla take to charge?
At a Supercharger, Tesla quotes up to 195 miles (about 314 km) in 15 minutes for the Model 3 Long Range RWD, which accepts up to 250 kW. The Model 3 RWD with an LFP battery peaks at 175 kW and takes about 24 minutes for 10–80%, according to EV-Database. On AC, the RWD accepts up to 11 kW.
Can you charge an electric car from a normal household plug?
Yes, but slowly. The AFDC puts a 120-volt Level 1 connection at about 1.9 kW, adding roughly 5 miles (8 km) of range per hour, and BYD's UK guide estimates around 12 hours at 3 kW. It works as a backup, but a wallbox is far more practical for regular use.
How long does a 7 kW charger take to charge an EV?
BYD's rule of thumb is 6–8 hours for a typical full charge. For a closer figure, divide the energy you need in kWh by 7: a car that needs 35 kWh takes about 5 hours. If your car's onboard charger is limited to less than 7 kW, it will take longer.
Why does EV charging slow down after 80%?
Charging power tapers as the battery fills, with the slowdown commonly described as starting around 70–80%. That is why fast-charging times are quoted to 80%, and why stopping at 80% on a road trip is often the quickest approach. Waiting for 100% on a DC charger means spending the slowest part of the session plugged in.
Does hot weather slow down EV charging?
The strongest recent heat data is about range rather than charging speed: Recurrent found about 5% range loss at 32°C and 17–18% at around 37–38°C. For charging, battery temperature matters, which is why cars precondition the pack before a fast charge. Parking in shade and navigating to the charger so the car can precondition both help.
Is it bad to DC fast charge every day?
Occasional fast charging is exactly what DC chargers are for. Geotab has reported that DC fast charging in heat accelerates battery wear, so in a hot climate it makes sense to use slower charging for everyday needs where you can. Our guide to maintaining your EV's high-voltage battery covers habits that help it last.
Is public EV charging free in Oman?
Not from 1 October 2026. Muscat Daily reports that public charging fees begin on that date, set by charger power: 50 baisa per kWh on chargers up to 90 kW, 90 baisa on 91–180 kW chargers and 120 baisa on chargers of 181 kW and above. Check the rate shown by the operator before you plug in.
