Welcome to our blog dedicated to answering the 43 most googled questions about EV chargers in the UK!
Whether you're a new EV owner or just considering making the switch, we understand that finding the right information about charging your electric vehicle can be overwhelming. That's why we've compiled this list of the most frequently asked questions about EV chargers in the UK, and we're here to provide you with clear and concise answers.
From the different types of EV chargers available in the UK, to how to use them, and how to choose the right one for your specific needs, we've got you covered. From the simple to the more complex questions, let’s get started!
1. What is an EV charger, and how does it work?
An EV (Electric Vehicle) charger is a device that supplies power via electricity to an electric vehicle's battery. There are different types of EV chargers, including Level 1, Level 2, and DC fast chargers.
Level 1 chargers use a standard 120-volt outlet and can take up to 24 hours to charge your electric vehicle. Level 2 chargers use a 240-volt outlet and can charge an electric vehicle in 4-8 hours. DC fast chargers are the most powerful of the three types and can charge an electric vehicle to 80% in as little as 30 minutes.
The charger is connected to an AC (alternating current) power source and converts the AC power into DC (direct current) power that can be used to charge the vehicle's batteries. When an electric vehicle is plugged into a charger, the charger communicates with the vehicle's battery management system to determine the battery's current state of charge and the maximum charging rate it can accept.
The charger then supplies the appropriate amount of current and voltage to the battery until it is fully charged or until the vehicle's battery management system stops the charging process to protect the battery from overcharging.
2. How much does it cost to charge an EV at a public charging station?
The cost of charging your electric vehicle in a public charging location will vary, depending on the charging speed, the location of the charging station, and the electricity provider for that location. Some locations in the UK offer free charging, whereas most charge by the hour or by kWh usage.
Those that charge at kWh often range in price between 10p and 30p, while stations that charge per minute can rise up to 50p. Much like petrol stations, these prices fluctuate and can vary from location to location.
Some charging networks may also charge a connection fee or subscription fee, and others may offer membership schemes or smartphone apps that can make the charging process more convenient and cost-effective.
You can use smartphone apps like Zap-Map and CarWow to find charging stations near you, as well as the UK Government EV charging map website.
