Electric vehicle charging times vary depending on three things: your car's battery size, the speed of your charger, and how much charge you're starting with. Use the calculator below to get an instant, accurate estimate — and find out whether you'll be ready by the time you need to leave.
Charging time depends on your battery size and charger speed. A typical 52 kWh battery charged from 20% to 80% takes around 15.6 hours on a 3-pin plug, just under 5 hours on a 7 kW home wallbox, or as little as 45 minutes on a 50 kW rapid charger. Use the calculator above to get an exact figure for your setup.
A standard 3-pin plug draws around 2 kW — the same as a kettle — and is the slowest way to charge an EV. A dedicated home wallbox typically charges at 7 kW or 11 kW, meaning it can charge your car three to five times faster overnight. Wallboxes are safer for regular use and can sometimes be installed with help from government grants.
Most EV manufacturers recommend keeping daily charging between 20% and 80% to preserve long-term battery health. Charging to 100% is fine occasionally — particularly before a long journey — but regularly doing so can accelerate battery degradation over time. Check your vehicle's manual for model-specific guidance.
kWh stands for kilowatt-hour and is the unit used to measure both battery capacity and energy consumption. A 52 kWh battery can store 52 kilowatt-hours of energy. If your charger delivers 7 kW, it adds 7 kWh of charge every hour — so charging from empty would take roughly 7.4 hours (52 ÷ 7), before accounting for charging efficiency losses.
Occasional use of rapid DC chargers is generally fine, but frequent reliance on very high-speed charging (50 kW+) can cause slightly more wear on the battery over time compared to slower AC home charging. For day-to-day use, a 7 kW home wallbox is widely considered the best balance of speed and battery longevity.
Not all the energy drawn from the grid makes it into your battery — some is lost as heat during the charging process. Most EVs are around 85–90% efficient when charging, meaning a 52 kWh battery may require closer to 58–60 kWh from the grid to fully charge. Our calculator uses the stated battery capacity as a guide; real-world times may be marginally longer.
Yes. EV charging equipment is designed and tested to be safe in wet conditions. Both home wallboxes and public chargers are weatherproof, and the charging connectors are sealed to prevent water ingress. It is perfectly safe to charge your electric car outside in rain or snow.
Your vehicle's maximum AC and DC charging speeds will be listed in the owner's manual or on the manufacturer's website. Plugging into a charger faster than your car's maximum accepted rate won't damage it — the car will simply draw at its maximum supported speed. For example, if your car supports 7.4 kW AC charging, connecting to an 11 kW wallbox will still only charge at 7.4 kW.
