How fast can my electric car charge?

The speed at which your car can charge depends on your vehicle and whether you are using a slow, fast, or rapid charger. The majority of cars will never hit the higher charge outputs on the Rapid charge points for the duration of the charge, as it can degrade the battery.

Slow Chargers
  • The most common slow chargers are rated at under 7 kW and are usually found in homes, although you may find them in workplaces and public sites.
  • As an average, a slow charger would complete a full charge anywhere from 8 hours to 12 hours. They are often known as "trickle chargers". They are cheaper to install and will have a lower per kWh cost compared to quicker charger methods.
Fast Chargers

Fast Chargers:

  • These chargers tend to be between 7kW to 22kW in power output and will normally be found in commercial premises or destination charge points.
  • As an average, a fast charge would complete in around 2-4 hours depending on car battery.
Rapid Chargers

Rapid Chargers:

  • These chargers tend to be "on-route" chargers that would be found at service stations on major road networks. They can be from 22+kW power outage, up to 100kW.
  • Rapid chargers can complete a charge in under an hour, but shouldn't be used to consistently charge a car. It could lead to battery degradation in future, meaning a loss of overall range.
  • These will always be DC chargers.
Ultra-Rapid Chargers

Ultra-Rapid Chargers:

  • Recently Ultra Rapid Chargers have started to grow in prevalence. These can charge above 100kW per hour, and will be found in charging hubs on major road networks. 
  • A good example of an ultra-rapid charge network is Clenergy EV partner era-Supercharge, who are building an ultra-rapid charger network in Scotland.
