Electric car charging: all you need to know

Comprehensive Guide to Charging Your EV in the UK

When you’re suddenly plugging in instead of filling up, there comes a whole host of questions and queries.

But charging an electric car doesn’t have to be complicated. With this detailed guide put together by CarSupermarket’s experts, you’ll have all the information you need to whizz away worry free.

Everything You Need to Know About Charging Your EV in the UK

Common charging points explained:

Home Charging Points

Home Chargers: Typically the slowest option, with power outputs between 3kW and 9kW. Depending on your EV’s battery size, a full charge from nearly empty can take between 6-12 hours, which is ideal for overnight charging. Plus, it keeps your running costs down, so your EV is ready to go each morning without breaking the bank.

Dig deeper into the world of EV charging

Rapid chargers usually use tethered cables, which are permanently connected to the charger. This means you can take the cable from the charging unit and attach it to your car to start charging – like you would fill up with fuel at a petrol station. Meanwhile, standard public chargers – and your home charging point - will require you to use an untethered cable. These cables normally come with the EV when you buy it and are stored in the boot or under the bonnet. You will need to plug one end into your car and the other into the charging point.

Understanding Charging Speeds and Times

  • Slow Charging: Generally adds 3-4 miles of range per hour.
  • Fast Charging: Adds about 15-30 miles per hour.
  • Rapid Charging: Provides 60-80% charge in 30 minutes.
  • Ultra-Fast Charging: Can provide up to 80% charge in 15-20 minutes.

Are electric car chargers universal?

Electric cars sold in the UK are compatible with most standard public chargers, so you can plug in your untethered cable and charge no problem.

For rapid chargers that use tethered cables, there will normally be two cables available. These will typically be the two most common connectors, CHAdeMO and CCS (Combined Charging System). Be sure to check your connection type before heading to a rapid charger, particularly if you have an older EV.

CCS is quickly becoming the standard charger for new EVs, so this likely won’t be something you’ll need to consider in the future.

Protect your battery: how to charge your electric car effectively

EV batteries are predicted to last well over 100,000 miles, and even up to 200,000, so most drivers won’t need to worry about a replacement for 15-20 years. However, electric car batteries do lose around 2% of their capacity each year, very gradually reducing the overall range. Luckily, there are several steps you can take to minimise how much capacity and therefore range your EV loses over time.

Minimise charging

Regularly charging your electric car to 100% can actually have a negative impact on its range over time. Imagine that your EV battery will get exhausted from being crammed full of power every night. Avoid leaving it on charge every night if you can and aim to keep the charge somewhere between 20% and 80%. Some EVs will also let you choose when it should stop charging, so the power is cut off after a certain period of time, protecting the battery. While rapid chargers are handy from time to time, you should avoid using them frequently. Batteries prefer to sip rather than slurp.

Can you charge an electric car in the rain?

If it starts to pour down and your EV is plugged in on the drive or elsewhere, don’t worry. Rain has no impact on charging, as all hardware has been designed to be used safely in wet conditions.
