EV Isolation Transformers — isolation transformers for EV charging stations
Country: United Kingdom · Model: EV Isolation Transformers
EV Isolation Transformers are single-phase and three-phase isolation transformers for electric vehicle charging points. They separate the charging point circuit electrically from the supply, following section 722 of BS 7671:2018. They are built to IEC 61558-2-4:2009.

Description
The transformer creates protective separation between the supply and the circuit that feeds the charging point. This is the kind of separation addressed by section 722 of BS 7671:2018, which covers electric vehicle installations. The design follows IEC 61558-2-4:2009, the standard for isolation transformers. The single-phase or three-phase version is chosen to match the charging point and the site supply arrangement. Power and voltage are not given in the available data, so they are agreed against the charger documentation and the project.
How to choose
The choice comes down to the number of phases. Take one phase for single-phase charging points and three phases for three-phase ones. Power and voltage should be checked against the charger documentation, so that the transformer is sized without excess margin. If the task is voltage adjustment rather than circuit separation, look at Rotavolt up to 60 kVA, and at the Voltage Optimisation unit for energy savings.

FAQ
Why does a charging station need an isolation transformer?
It separates the charging point circuit from the supply electrically. This protective separation is covered by section 722 of BS 7671:2018.
Which standard do these transformers follow?
IEC 61558-2-4:2009.
How many phases do EV Isolation Transformers have?
They are made for 1 or 3 phases, depending on the charging point.
Can this transformer be used to raise or lower the voltage?
Its purpose is protective separation of circuits. For voltage adjustment there is Rotavolt up to 60 kVA with 0–115 % of input at the output.
Is the transformer power rating given in the data?
No, the available data give only the phases, the standard and the purpose. Power and voltage are clarified from the charger documentation.
