Electric vehicle (EV) charging has developed massively in recent years. From a sparse collection of slow-charge points scattered across the south, an impressive network of reliable, fast-charging points now exists. This explosion in infrastructure was necessary to make EV ownership a practical, affordable option for the masses. Initially, only the brave, adventurous drivers were willing to invest in electric vehicles. But from its humble beginnings and thanks to intense Government support, electric vehicles now make up around 5% of all cars on UK roads. This might not sound that impressive, but EV ownership is growing rapidly, and EVs now account for over 23% of all new cars.
Although the popularity of EVs is rising, for many, it remains a daunting prospect, with charging and range anxiety being the top concerns. In this blog, we’ll take a detailed look at how EV charging systems work and hopefully answer some of your burning questions.

What Is an EV Charging System?
An EV charging system is the infrastructure used to charge electric vehicles (EVs). It’s sometimes called Electric Vehicle Supply Equipment (EVS), and it is the hardware and software used to transfer electrical energy from the grid to an EV battery. Typically, an EV charging system includes:
- EV charge points
- Charging cables and connectors
- Electrical supply
- Charge management software
- Energy management systems
- Load balancing technology
- User payment systems
How Does an EV Charging System Work?
Filling up a car with petrol or diesel is easy, but charging an electric car requires a little more thought and planning. So, how does the charging process actually work?
- Plug the Charging Connector into your car
- The charger and car communicate using the Battery Management System software
- The charger sends power to your car
AC vs DC Charging
Depending on the charger, electricity is transferred to the vehicle using AC or DC power.
- AC chargers pass AC power directly from the grid to the EV. EV batteries can only store DC power, so the EV’s onboard charger converts it to DC.
- DC charging stations convert AC power to DC power before passing it to the EV. This allows the system to charge the vehicle much faster.

Types of EV Charging Systems
Slow AC 3kW
Slow chargers a common type of EV charger. They are typically installed in homes, workplaces, and on-street residential areas, where the car can be left to charge for long periods. An average EV takes about 16 hours to fully charge using a slow AC charger.
Fast 7kW
Fast DC chargers range from 7 to 22kW. Charging can add around 30 miles of range in an hour. This type of charger is usually found at home and destinations such as train stations, leisure centres, or retail outlets.
Rapid 50kW
Rapid DC chargers can add up to 100 miles of range in around 35 minutes. They are common in locations where the dwell time is less than an hour, such as supermarkets, retail outlets, and service stations.
Ultra Rapid 150kW
Ultra-Rapid chargers are the fastest way to charge an electric vehicle. They range from 150kW to 350kW and can charge a car to 80% in around 30 minutes. This type of charger is found in public network charging facilities, and they’re growing in popularity due to demand for convenient high-speed chargers.
How Long Does It Take to Charge an EV?
Charge times depend on the charger type and speed, as well as the battery size.
Typical EV Charging Times
| Charger Type | Power Output | Typical Charging Time* |
|---|---|---|
| Home Charger | 3.6kW | 12 to 20 hours |
| Fast Home/Workplace Charger | 7kW | 6 to 12 hours |
| Rapid DC Charger | 50kW | 45 to 90 minutes |
| Ultra-Rapid DC Charger | 100kW to 150kW | 20 to 45 minutes |
| High-Power DC Charger | 200kW to 600kW+ | 10 to 30 minutes |
*Charging times vary depending on battery size and vehicle capability.

Chargers, Connectors and Adapters
It’s easy to get confused when it comes to EV charger connectors. This is because there is no universal connector for electric vehicles and their different chargers. In the UK, the industry used three types of connectors:
AC Type 2: Used in AC slow and fast charge points. Can charge up to 22kW.
CHAdeMO: Used in DC charge points 50kW and above. Currently being phased out and replaced with CCS.
CCS Combo: The most common connector used in rapid and ultra-rapid chargers 50kW and above.
The Benefits of EV Charging Systems for Businesses
From attracting valuable customers and employees to supporting sustainability goals and unlocking new revenue streams, the benefits of installing EV charging systems for businesses are significant.
EV ownership is increasing rapidly, so providing on-site charging facilities is seen as a huge benefit. At sites with on-site charging facilities, customer dwell time and footfall increase. Companies that provide charging often see stronger employee loyalty and find it easier to recruit high-quality staff. And business clearly demonstrate their commitment to sustainability and green energy.
