Summary

The Ratio io7 22kW dual socket with CT metering is a three-phase commercial charging bollard giving two bays up to 22kW each. Its CT clamps read what the whole site is drawing and hold charging back when the supply gets tight.

Those readings are not MID-certified and carry no legal standing for billing, so specify this version only where charging is included rather than sold. If you will invoice tenants, staff or the public per kWh, the MID io7 is the one you need. Untethered Type 2 sockets, OCPP 1.6 and dusk-to-dawn LED area lighting throughout.

CT or MID - which one should I be buying?

Buy CT if the electricity is free to the user and you simply want to see and control what the chargers draw. Buy MID if anyone is invoiced for it. CT clamps are a protection and monitoring device, and their readings are not MID-certified, which means they are not a lawful basis for charging by the kWh in the UK. Free staff and visitor charging, fleet monitoring and load management are exactly what this version is for.

Does 22kW need a three-phase supply?

Yes, for the full output. Each socket draws up to 3 x 32A at 400V, so a three-phase supply is required to reach 22kW. On single-phase sites the 7.4kW io7 is the correct model rather than this one.

Will every EV charge at 22kW?

No, and that is down to the car rather than the charger. A vehicle charges at whatever its onboard AC charger allows, commonly 7.4kW or 11kW, so only EVs rated for 22kW AC will take the full amount. The charger delivers what each vehicle can accept.

Can two vehicles charge at the same time?

Yes. Both sockets are live together and the CT load balancing decides how much of the available supply each one gets, easing charging back as other demand on the site rises so the incoming supply is never overloaded.

What back office does it work with?

Any OCPP 1.6 platform, including Ratio's own. That keeps monitoring, RFID access lists and reporting under your control rather than tied to one supplier, and firmware updates arrive over the air.

Is grant funding available?

The Workplace Charging Scheme is open to businesses, charities and public sector organisations and covers up to 75% of purchase and installation costs, capped at 500 pounds per socket and 40 sockets per applicant. This unit counts as two sockets. Funding is confirmed to 31 March 2027.
