Common EV Charging Speeds
Typical charger power outputs used when estimating electric vehicle charging times.
| Charger Type | Typical Use | Power Output |
|---|---|---|
| Level 1 | Standard household socket | ~2.3 kW |
| Level 2 (Home) | Dedicated home wallbox | 7 – 11 kW |
| Level 2 (Public) | Public/workplace charge point | 11 – 22 kW |
| DC Rapid | Motorway service & retail sites | 50 kW |
| DC Ultra-Rapid | High-power public charging hubs | 150 – 350 kW |
| Typical EV Efficiency | Mixed driving conditions | 3 – 4.5 mi/kWh |
Electric Car FAQ
Everything you need to know about estimating electric vehicle range, energy use, and charging time.
Multiply your battery’s usable capacity in kWh by your car’s efficiency in miles per kWh. For example, a 60 kWh battery with an efficiency of 3.5 miles per kWh gives an estimated range of around 210 miles at full charge.
Charging time depends on the size of the charging gap and the power of your charger. A rough estimate is to divide the kWh needed by the charger’s power output in kW. A 40 kWh top-up on a 7kW home charger takes roughly 5.7 hours, while the same top-up on a 50kW rapid charger takes under an hour.
Most modern electric cars achieve between 3 and 4.5 miles per kWh in mixed driving conditions. Smaller, lighter EVs tend to sit at the higher end, while larger SUVs and performance models are typically less efficient.
Level 1 charging uses a standard household socket and delivers around 2.3 kW, Level 2 uses a dedicated home or public charge point delivering 7 to 22 kW, and DC fast (rapid) charging delivers 50 kW or more directly to the battery for much quicker top-ups.
Yes, cold weather can reduce an EV’s real-world range by roughly 10-30% due to battery chemistry becoming less efficient and additional energy being used for cabin heating.
