How do I know if my charger has a MID meter?

Check the type plate: a MID meter carries the letter M with a year inside a rectangle, next to the CE marking. Or use the charger check at joulo.nl/en/check-charger • pick your brand and model and see immediately whether your charger qualifies.

Is my charger MID-certified if it has a CE marking?

No. CE is a general product marking and says nothing about the meter. MID is a separate metrology marking: the letter M with a year inside a rectangle, next to the CE marking.

Is a separate MID sub-meter in the meter cupboard a solution?

No. For home charging only the meter inside the charger itself counts. A sub-meter in the meter cupboard or a separate box next to the charger is not a valid registration route. The alternatives: an upgrade to a charger with a built-in MID meter, or a Secondary Allocation Point (SAP) with your grid operator.

Does my charger have a MID meter?

How to check in two minutes whether your charger has a factory-fitted MID meter: type plate, brand list and the charger check.

ERE registration has one hard technical requirement: your charger has a MID-certified meter, factory-fitted. Without that meter your charging sessions are not reliable enough to register with the NEa. Here is how to check your charger in two minutes.

The fastest route: check your brand and model

Use the charger check. Pick your brand and variant and see immediately whether your charger qualifies for ERE registration. The check is based on our catalog per brand, model and variant.

Checking yourself: the type plate

Look at the sticker or type plate on your charger. A MID-certified meter carries the metrology marking: the letter M with a year inside a rectangle (for example M24), next to the CE marking. Note: CE alone is not enough • it says nothing about the meter. No M marking? Check the manual or spec sheet for "MID" or the meter standard "EN 50470".

Three practical examples:

- Tesla Wall Connector: the MID variant has a part number starting with 1529455-5. - Zaptec: the Go 2 and the Pro have a MID meter as standard. The original Go does not. - Easee: the Charge Max and Charge Pro do, older Easee models do not.

Which chargers have a factory-fitted MID meter?

Among others: Tesla Wall Connector Gen 3 MID, Zaptec Go 2 and Zaptec Pro, Easee Charge Max and Charge Pro, the Alfen Eve series, Peblar Home Plus and Business, Volt Time, Blue Current, NexBlue, Ecotap and Ohme. Within one brand it often differs per variant: the Smappee EV Wall is MID as an EVWC article number, but not as an older EVW or EVWL number. So always verify your exact model with the charger check.

No MID meter? These are your options

1. Upgrade to a charger with a built-in MID meter. Request a quote • an installer from the Joulo network replaces your charger. 2. A Secondary Allocation Point (SAP) with your grid operator: a separate branch with its own meter (€200–€300 setup plus monthly costs).

A separate sub-meter in the meter cupboard is not a valid registration route for home charging. And note: registration only covers kWh the MID meter itself has measured. Sessions from before the meter never count, not even retroactively. Your sessions count from the moment the MID meter is in place.
