How To Charge Your Electric Vehicle

The range of connectors and devices can make charging your electric vehicle seem overwhelming, but in reality, it’s quite simple. Here at Griffin Mill, we’re untangling the myths behind electric car charging and aim to equip you with the knowledge you need to make an informed decision when choosing your next electric vehicle.

Types of Charging Available

Plug-in vehicle charging depends on both the vehicle’s onboard charger and the external charging infrastructure. A vehicle will always charge at the lowest maximum rate permitted between the charger and the vehicle.

Charge points are primarily defined by the power (kW) they provide. Below are the common classifications and average times for a 100% charge of a typical EV:

Slow (AC): 3–7 kW wallboxes—overnight charging.
Fast (AC): 7–22 kW—charges in 3–8 hours, ideal for home and business.
Rapid (DC): 50–149 kW—10–80 % in 20–40 minutes.
Ultra‑rapid (DC): 150–400 kW—10–80 % in 10–20 minutes, depending on the vehicle.

SLOW CHARGING
This method uses a standard household 3‑pin socket. While convenient, it's the slowest option, and charging can take over 20 hours depending on your vehicle and battery size. We recommend having your household socket assessed by a certified electrician before regular use.

FAST CHARGING
Fast charging was developed specifically for EVs. Most domestic properties can support a 7 kW wallbox, which can fully charge a vehicle in around 7–8 hours, ideal for overnight use. Certified installers will ensure a safe, isolated circuit, and some systems integrate with smartphone apps for convenient scheduling and monitoring.

RAPID CHARGING
Rapid chargers use direct current (DC) to deliver high power to the battery quickly. These chargers typically bring the battery from 10% to 80% in under 40 minutes, then slow for the remaining 20% to preserve battery health.

COST

Charging an EV can be much cheaper than filling up with petrol. You could charge a fully electric vehicle like the Nissan LEAF for around £2.35. This would give you a range of approximately 200 miles or 1.2p per mile. Driving the same distance in an equivalent petrol or diesel car would cost more than £20.

Electric vehicles are generally more efficient and cost-effective than petrol or diesel cars. Many EVs include eco-modes to help maximise range. Driving more smoothly and using less heating or air conditioning can also extend battery life. Thanks to the UK’s expanding charging infrastructure, range anxiety is becoming a thing of the past.

ZAP MAP & CHARGING POINTS

The UK now has over 80,000 public charge points across more than 39,000 locations, including thousands of rapid and ultra-rapid chargers. Use the Zap Map tool to search by connector type, speed, availability, or location, ideal for local trips or cross-country journeys.

The charging network continues to grow rapidly, with more charge points than fuel stations in the UK and the number is increasing every month.
