How to Choose the EV Charging for Commercial Property?

W). It is a common charging method, especially in home and commercial environments, for electric vehicles that require higher charging speeds.

The most common home EV charging speeds include:

3 kW—very slow (three-pin plug)
6kW—slow (home EV charge point)
4kW – fast (home EV charge point)
Up to 22kW—very fast (home EV charge point)

The 2.3kW three-pin plug is the slowest option available and is typically recommended only as a backup. The 7.4kW charger, however, is one of the most popular choices for home EV charging and is commonly recommended by installers.

The 22 kW 3-phase charger is the fastest EV charger that can be installed in your home today, but there are several conditions that need to be met in order to use it.

First of all, the charging point must support “three-phase compatibility” and be connected to a three-phase power supply. In addition, the electric vehicle itself needs to support a charging power of 22 kW.

So, what is three-phase charging?

AC power can be categorized into single-phase and three-phase systems that support EV charging through single-phase and three-phase power outlets, respectively.

The main difference between the two is that single-phase electricity transmits power through one conductor, while three-phase electricity transmits through three conductors. Compared to single-phase charging, three-phase charging has a higher power transfer capacity of 22 kilowatts.

22 kW charging refers to the speed at which electricity is transferred from the charger to the electric vehicle, which is three times faster than 7 kW charging. Only properties with three-phase power can support this type of charging.

As most homes in the UK do not have three-phase power, 22 kW EV charging is not common in homes.

Most homes in the UK use single-phase power rather than three-phase. If you want to check whether you have three-phase power in your home, you can contact your electricity supplier or check your electricity meter, which will have three sets of wires connected to it.

If you need a three-phase supply, for example, in order to install a 22kW three-phase electric car charger, you can contact your District Network Operator (DNO) to upgrade. The cost of upgrading to a three-phase supply can be high, typically between £3,000 and £15,000. Due to the higher cost, many EV owners choose to install a 7kW single-phase charger, which is the fastest charging option available on single-phase power.

While it may seem like the best option to go for 22kW charging, it’s important to note that not all EVs are compatible with 22kW charging. For example, the BMW i3 and Renault ZOE can handle 22kW, but many other models, like the Tesla Model 3, may only accept lower power levels depending on their onboard charger.

The onboard charger (OBC) inside an EV determines the maximum rate of power the car can accept, which currently ranges between 3.6kW, 7kW, and in some cases, 11kW. For instance, even with a 22kW charger, if your car only supports 3.6kW, that’s the maximum power it will be able to draw.

Since most properties in the UK do not have a three-phase power supply, plus it can be expensive to have the existing systems upgraded, it may not be worth it to install a 22kW three-phase charger on your residential property.

It may not be such a great idea, more so because most EVs won’t be able to take full advantage of a 22kW charger in their home anyway.

Since most EV charging in homes takes place overnight, even if you have a three-phase power supply and a compatible electric car that could charge between 11kW to 22kW, it wouldn’t make a difference since it wouldn’t matter how fast or slow the charging took place.

To make it clearer, imagine charging your smartphone with a fast charger overnight while you’re asleep. While it is true that, as compared to a regular charger, it will charge in one hour instead of two.

However, in both scenarios (slow and fast charger), your phone will be fully charged when you wake up in the morning and you won’t have noticed any time-saving.

For EV drivers who usually charge their EVs at home overnight, it wouldn’t be very wise to invest in a 22kW three-phase charger. For them, a 7kW charger would be more than enough.

Charging an electric vehicle (EV) at 22 kW takes varying amounts of time depending on four key factors:

Your property’s power supply
The EV’s charging capability
The EV’s onboard charger
The size of the EV’s battery

In the UK, EV chargers are generally classified into three types based on their charging speeds: slow, fast, and rapid/ultra-rapid chargers.

Slow chargers, which provide up to 3.6 kW of power, typically take between 6 and 12 hours to fully charge a vehicle, making them ideal for overnight home charging.
Fast chargers, offering a power range of 7kW to 22kW, take about 3 to 5 hours to fully charge an EV and are the most common type of public charging station.
Rapid and ultra-rapid DC chargers, capable of delivering 50 kW to 350 kW, can charge an EV up to 80% in under 20 minutes, commonly found at shopping centers, parking lots, and service stations.

A 22kW three-phase charger charges three times faster than a single-phase 7kW charger, significantly reducing the charging time. However, the vehicle’s battery size and health also play an important role. The larger the battery, the longer the charging time.

Here are some typical examples of battery size, charging power, and charging time:

A 32kW battery will take around 9 hours with a 3kW charger and 4 hours with a 7kW charger.
A 40kW battery will take around 11 hours with a 3kW charger and 4.5 hours with a 7kW charger.
A 60kW battery will take around 17 hours with a 3kW charger and 7 hours with a 7kW charger.
A 100kW battery will take around 27 hours with a 3kW charger, 11.5 hours with a 7kW charger, and 4.5 hours with a 22kW charger.

Therefore, using a 22kW charger significantly shortens charging time, especially with larger battery capacity.

The cost of installing a 22kW EV charger is generally higher than the installation of a 7kW standard EV charger.

Material and Labor Costs

Since a 22kW charger is three times as powerful as a 7kW charger, more materials and larger gauge cables are required. The installation process involves more electrical work and a relatively long installation and commissioning time.

Additional costs

In addition to the installation cost, an extra £700 to £900 may be required to purchase additional materials or to complete more complex electrical work.

Government subsidy

Under the government’s Electric Vehicle Home Charging Scheme (EVHS), you can receive a grant of up to 75% of the cost of your charger, capped at £350 per installation.

This subsidy can help reduce the cost of installation, depending on your installation and the policies in your area.

To benefit from the grant, you must:
