What is an EV charging point? 

For those not in the know, an EV charging point, also known as a charge point, is a specific piece of equipment that supplies electrical power for charging plug-in vehicles. These include buses, cars, bikes, and trucks, to name a few. EV charging points can either be free-standing or wall-mounted, untethered or tethered. They also come in a wide range of power outputs – these include 3 kW, 4 kW, 7 kW as well as 22 kW. The size, type and power rating depend on whether a person wants to charge their electric vehicle at work, at home, or on the public network.

Faster charging speed

One of the main advantages of using the 3 phase EV charger is its ability to deliver higher power levels. This results in significantly faster charging times when compared to single phase chargers. The higher power capacity of 3 phase chargers lets electric vehicles charge more quickly, which is especially advantageous for drivers who need to recharge their vehicles in a shorter amount of time.

Reduced charging time

The increased power output of a 3 phase EV charger means it has a reduced charging time. This is particularly beneficial for electric vehicle owners, especially if they need to charge their vehicles quickly, such as in places like commercial and public charging stations.

Efficient power distribution

The phase power distribution tends to be more efficient and balanced when compared with single phase power. This efficiency helps to prevent power imbalances and reduces the load on the electrical grid. This makes it more suitable for high-power applications such as EV charging. 

Suitable for fleet charging

Businesses that use electric vehicle fleets can take advantage of 3 phase EV chargers. This is because they can charge multiple vehicles at the same time faster. This is essential for maintaining the operational efficiency of a fleet. 

Optimised for higher-power charging

As electric vehicle battery capacities grow, the demand for high power charging stations also increases as well. 3 phase chargers are generally considered better equipped to handle these types of higher power requirements, ensuring compatibility with future electric vehicle models. 

Reduced charging station footprint

Faster charging times with 3 phase chargers mean that there are fewer charging stations that are needed to accommodate the same number of vehicles. This ends up optimising space and reducing installation costs. 


Investing in a 3 phase EV charger ensure it is compatible with future electric vehicle models that may require higher charging speeds due to larger battery capacities.

Compatible with industrial and commercial power infrastructures

Most commercial and industrial facilities are equipped with three-phase power infrastructure. Using a 3 phase EV charger in such locations often allows for more efficient utilisation of existing power systems. This, therefore, reduces the need for costly upgrades. 

How to charge an electric vehicle? 

Charging at work

Charging an electric vehicle at work can be a way to add range to a vehicle while parked during work hours. The most popular type of workplace charge point is a 7 kW wall-mounted charge point. They are typically compatible with most electric vehicles and are the cheapest to install. That said, some businesses do offer faster 22 kW units that can be either free-standing or wall-mounted.

Charging at home

This is the most convenient and cost-efficient option when it comes to recharging an electric vehicle. It can be done in one of two ways. The first is by plugging the vehicle using a regular domestic three-pin socket, or by a dedicated home car charging point. Usually, dedicated home charging points are wall-mounted and rated up to 7 kW. 

Charging on the public network

This can be done in places such as hotels, supermarkets, public car parks, and even on the road. These charge points offer a mix of fast and rapid charging options, and they are typically free-standing. They are also often untethered, so a driver would need to provide their own EV charging cable. 

Bottom line

Overall, while it is important to note that 3 phase chargers tend to offer several advantages to users, they also require proper installation and electrical infrastructure support. Homes and locations that only have single phase power may need additionalelectrical work to accommodate a 3-phase charger. So, before buying a 3 phase EV charger, it is highly recommended a buyer consults with an electrician to assess their existing electrical infrastructure and determine the feasibility of its installation. 

On the whole, for those looking for a faster and more efficient way of charging their electric vehicle, especially in high-demand situations, a 3 phase EV charger can provide potential benefits and contribute to a more convenient and seamless electric vehicle ownership experience.
