How long does it take to charge an electric car?

Are you wondering how long it takes to charge an electric car? Discover everything you need to know about charge speeds, public and home charging, and different factors that can affect EV charging times.

Read on to find out more, with this handy guide from Honda.

How long does it take to charge an electric car?

Electric car charging times can vary, taking anywhere from 30 minutes to 12 hours. Depending on the size of your battery and the charge point output, you will see different results. While slower, charging overnight at home could result in some great savings.

• Two of the biggest contributors to significant charge times are having a large car battery and a low-power charge point.
• Charging from mains power may take longer than any other charge point, as its power output is usually only 3.7kW. This could take a 60kWh battery almost 16 hours to charge.
• Using a 7kW home charger could charge the same vehicle in as little as 8 hours from empty, and most homes can easily support this.
• Depending on your driving habits, you may not be charging from empty every day.
• High-powered electric charging points are publicly available to you. These can range from 50kW, all the way to 100+ kW, charging your vehicle in 30+ minutes.

Factors that can affect EV charge times

Many factors can affect EV charging times. While some make sense, others might catch you by surprise. Knowing what these are can help you quickly power your car’s battery in an energy-efficient way. Learn what can determine how long it takes to charge your electric car.

Battery Size

The battery size is one of the most important measures of your EV’s charging time. The larger it is, the longer it will take to charge.

Battery Charge

Charging the battery from empty takes longer than recharging it from partially full.

Capped Charging Rate of Vehicle

Most manufacturers limit your electric car’s charging speed – regardless of charger, you won’t be able to exceed this value.

Capped Charging Rate of Charge Point

Charge points may have charging rate caps – regardless of charger, you won’t be able to exceed value.

Temperature

The charging time of your electric car’s battery will be slower during colder weather as well as during extremely hot spells.

Electric car charge times

There’s no catch-all solution for determining charge time to the minute. With weather, charge rates, battery deterioration, and your own driving habits it’s hard to say how long things will take. It’s possible to get somewhere close though. While generalised, the examples in this E charging time chart should give an idea of your average charge time. These assume a healthy battery, ideal weather, and charging your battery from 0-100%.

Estimating charging times

While most manufacturers will probably have manuals and webpages to confirm the time to charge, it’s possible to figure out an estimate yourself by doing this:

· Get your Battery Size
· Divide it by The Charging Speed
· The result is your Time to Charge

While there are a lot of numbers, it shows that, in general, charge times can take anywhere from 30 minutes to 28 hours depending on the chargers you use. The gap between charge times increases exponentially the lower the charging power.

Public vs home charging

Depending on your lifestyle, you may use one of these options more than the other. While home charging can be convenient, it’s often slower than public charging. However, public charging may be more expensive or require you to sign up to an app to access it.

Home charging

Your electric car charging time at home will often be slower. It is better done overnight for anything more than a quick power top-up. Home charger’s kW power options include:

3.7 kW – on average, these will take 20 to almost 30 hours to charge.
7 kW – are the most recommended home charge points, with EV charging times between 10 and 15 hours on average.
22 kW – these are rare, expensive to fit, and require a 3-phase home electricity supply that can support them. They’re mostly seen in Tesla models.

Electric Car Charging at home

Public charging

Public charge points offer fast charging for electric cars, perfect if you need to top up during a long journey. However, they may not be ideal for charging from empty to full, depending on your day. Charge times can vary, based on power. The two most common charge types are:

50 kW – these can reduce EV charging times to less than two hours for even a large battery.
150 kW – while rarer, 150 kW charge points will top up a battery from empty in less than an hour.

Top-up charging

One of the most convenient ways to charge your vehicle is to do so while parked. That may be overnight, at work, or while at the gym or shopping for groceries. Many car parks offer charge points. The benefits of this include:

• You never have to worry about running empty, making it incredibly convenient.
• If the charge point is free to use, you could save money on your electricity bill compared to topping up at home.
• Many public charge points in parking locations are lower powered, making them ideal for prolonged charging.
• It could save you time, visiting charge points while travelling.

Electric car charging times: FAQs

How long can an electric car sit without charging?.

While this will depend on your vehicle, an EV can sit for months without charging. Your battery level can also impact the time your vehicle retains its charge, and, contrary to what you may think, a charge of around 50% is ideal.

How long will an electric car run on a full charge?.

Your electric car’s run time will depend on a few factors, mostly related to your battery’s size and its condition. Generally, this is determined by range, which is the number of miles your vehicle can run compared to its charge. Older EVs on average will run for 160km, though more modern vehicles can range from 400km to 560km.

Do electric cars charge while driving?.

No – though there’s a caveat to this. EVs are energy negative while driving, but regenerative braking can restore some of the lost energy. This makes them more energy efficient but doesn’t constitute self-charging. Think of it more as partial recycling.

How long do electric car batteries last?.

On average, electric car batteries last more than 160,000km or roughly 15-20 years. Though, there are reports of EVs lasting for more than 320,000km.

Can top-up charging ruin your EV battery?

Generally, no – top-up charging shouldn’t ruin your EV battery. Most battery management systems have countermeasures for constant fast charging too and most vehicles have innate caps to protect their batteries. However, in some instances, it may be worth charging to less than 100% to preserve battery health.

Can you sit in an EV while charging?.

An EV is safe to sit in while charging. But if you rely on any electric device for your health, such as a pacemaker, it’s recommended you don’t sit in the vehicle while it’s charging. The electromagnetic fields could interfere with the device’s function. If you’re in doubt about this, seek advice from a medical professional.
