Which EV Charger is fastest?
Superfast 22kW-100kW+ chargers are also available, and customers may request them if they have an electric vehicle which can utilise these high charging speeds.
Unfortunately, most EVs are currently unable to charge that fast, meaning the extra power isn’t necessary for the majority of EV owners.
If a customer does request a 22kW charger, keep in mind that EV chargers that are 22kW or faster will require a three-phase connection to deliver the high charging speeds.
What’s a three-phase connection?
Some homes in the UK are powered by a single-phase connection - whereas others are powered by a three-phase connection.
A single-phase connection uses one live wire to deliver electricity
A three-phase connection utilises three live wires, meaning you could connect to all three for greater charging power
Most UK homes have a single-phase connection right now. However, customers looking to install an ultra-fast charger may be able to upgrade to a three-phase connection by contacting their energy supplier.
Is surge protection required when installing EV Chargers?
Whilst not strictly necessary, our renewables team does recommend installers equip each building with a SPD (surge protection device) installed in order to protect EV chargers.
SPD’s are usually fitted in fuse boxes or consumer units to protect EV chargers (and other electronics) from damage in the event of a power surge.
Do all EVs use the same plug?
Since 2014, it has been mandatory for electric vehicles to use the same ‘Type 2’ connector socket.
If a customer owns a pre-2014 electric vehicle, it may use the differently shaped ‘Type 1’ connector - however we recommend advising customers to install a type 2 connector regardless - especially since type 2 to type 1 adaptors are available.
