What are the EV charger types?

In the world of electric vehicles, understanding the diverse array of EV charger types is paramount, especially for London’s domestic and commercial audience. EV charger types can broadly be categorised into two main groups: AC (Alternating Current) and DC (Direct Current) chargers.

AC chargers

AC chargers are the familiar charging units found in homes, workplaces, and even some public charging stations. These chargers supply power to your EV by converting alternating current from the grid to direct current within your vehicle.

AC chargers are known for their reliability and versatility. They come in various power levels, including 3kW, 7kW, and 22kW, offering different charging speeds. They are ideal for overnight charging, ensuring your vehicle is ready to go in the morning.

AC chargers are cost-effective and provide a steady, controlled flow of electricity, which is crucial for the long-term health of your EV’s battery.

DC chargers

DC chargers, or Direct Current chargers, are the speedsters of the electric vehicle charging world. Unlike AC chargers, they supply electricity in its native form – direct current – which makes them significantly faster at recharging your EV. These chargers are commonly found at public charging stations, where quick top-ups are essential for busy Londoners on the move.

The key characteristics of DC chargers that set them apart are their rapid charging capabilities. They offer high-power charging, often in the range of 50kW to 350kW, allowing you to replenish a substantial portion of your EV’s battery in a short time.

AC vs DC EV charging: Make an informed decision

let’s delve into the comparison between AC (Alternating Current) and DC (Direct Current) EV charging. This comprehensive discussion will help you make an informed decision about which charging method best suits your needs.

Charging speed

DC chargers are renowned for their rapid charging capabilities. These chargers deliver a significantly higher power output, typically ranging from 50kW to 350kW. Such power levels allow for quick top-ups and substantial battery replenishment in a matter of minutes.

In contrast, AC chargers offer a slower charging pace. They come in various power levels, such as 3kW, 7kW, and 22kW, which are notably slower than DC chargers. This makes AC charging ideal for situations where time is not a pressing concern.

Cost efficiency

AC charging tends to be more cost-effective than DC charging. The rationale behind this cost efficiency lies in the infrastructure and power requirements of each charging type. AC chargers are designed for everyday use, whether at home, in workplaces, or in other domestic settings. They operate within the standard electrical grid, consuming electricity at a rate comparable to household appliances.

DC charging, on the other hand, is inherently more expensive. The high-power charging capabilities of DC chargers, which are essential for rapid charging, require specialised infrastructure and higher operating costs. Public charging stations equipped with DC chargers often pass these higher costs on to users.


The majority of electric vehicles are equipped with a universal charging port that can handle both AC and DC charging, making it simpler for EV users to access a variety of charging stations. This versatility means that you can utilise both AC and DC charging options without worrying about compatibility issues.

However, it’s crucial to examine the maximum charging capacity of your EV’s onboard charger. The onboard charger in your electric vehicle determines how fast it can accept electrical power. If your EV’s onboard charger can handle DC fast charging, you can fully leverage the rapid charging capabilities offered by DC chargers. On the other hand, if your EV’s onboard charger is limited to AC charging speeds, you’ll be restricted to the rate at which your vehicle can accept electricity.

Public vs. home charging

The choice between AC and DC charging also hinges on where you primarily charge your electric vehicle. This distinction is particularly crucial for domestic users in London.

AC chargers are commonly found in homes and are inherently suited for domestic use. They are specifically designed for residential charging, offering a straightforward and convenient charging experience.

On the other hand, DC chargers are predominantly located at public charging stations. They are tailored for situations where you need a quick top-up on the go.

Installation considerations

Installation considerations play a significant role in determining the suitability of AC and DC charging.
AC chargers are notably straightforward to install, particularly for domestic users. These chargers are designed for residential use and operate on standard household electrical connections. This means that the installation process is relatively simple.

In contrast, DC chargers are considerably more complex to install. These chargers demand a direct current (DC) power supply, which isn’t readily available in most residential settings. Installing a DC charger typically involves specialised electrical work, infrastructure upgrades, and potential coordination with public charging station providers.


DC chargers typically require more maintenance compared to AC chargers. The primary reason behind this is the complexity of DC charging infrastructure. DC chargers are high-powered, intricate devices with various components, which can be more prone to wear and tear.

On the other hand, AC chargers are generally more robust and require less maintenance. These chargers are simple, reliable, and have fewer components that can break or malfunction. They are designed for everyday use, whether at home or in workplace charging stations.

What’s the main takeaway?

If you’re a domestic EV user in London, AC charging is a practical and cost-effective choice for overnight charging at home. It’s budget-friendly, easy to install, and requires minimal maintenance.

However, for those moments when you need a rapid top-up on the go, DC charging at public stations becomes invaluable. Commercial users and businesses in London may opt for a mix of AC and DC charging, depending on their specific needs and the types of services they provide.
