Metering of the charging process

Energy consumption in a charging infrastructure may be metered and billed either centrally for all charging points or by individual charging point.

Metering for the entire charging infrastructure

  • Fewer installation expenses and costs for later extensions.

  • A single metering device for the energy supply is all that is needed, covering all charging points.

  • Accessibility to the metering device is required for the metering point operator.

  • The consumption per charging point can be metered and allocated via the back-end system, in conformity with calibration regulations.

  • A back-end system provides independent settlement of electricity consumption, directly by the user or using a service provider chosen by the user.

  • Access to the charging infrastructure may be set up in a private arrangement (e.g. parking areas at a residential building or company car park), publicly or semi-publicly (e.g. a retailer's car park).

  • Individual charging points within the infrastructure may be fitted with an additional meter and an e-pager as a controllable consumption unit under Section 14a of the EnWG (Energy Industry Act).

Metering per charging point

  • Higher installation expenses when fitting and extending.

  • Free choice of energy provider per charging point is possible, and direct billing of electricity consumption between energy provider and a distinct user of the charging point.

  • Accessibility to metering devices is required for the metering point operators.

  • Fitting of the charging point as a controllable consumption unit under Section 14a of the EnWG using an integrated e-pager is possible at little expense.


The electricity consumption of the individual charging point is measured via a meter (modern metering device or intelligent metering system).

The electricity consumption of the individual charging point is measured via a meter (modern metering device or intelligent metering system). To take advantage of reduced grid fees under Section 14a of the EnWG (Controllable consumption devices) a control device is integrated that allows for limitation of charging periods. Periods are determined by the network operator.

The electricity consumption of several charging points in a property is measured via individual meters (modern metering devices or an intelligent metering system). To take advantage of reduced grid fees under Section 14a of the EnWG (Controllable consumption devices) a control device can be integrated per charging point that allows for limitation of charging periods. Periods are determined by the network operator.

The electricity consumption of the all charging points is measured via a meter (modern metering device or intelligent metering system).

Communication of metering data

Where a modern metering device is used for measuring electricity consumption, the meter reading is performed annually at the location.

If metering of electricity consumption is carried out via an intelligent metering system, regular remote reading is performed and values made available on an online portal.

Reduced grid fees

An electric vehicle or the charging infrastructure can be set up as a controllable consumption device under Section 14a of the Energy Industry Law (EnWG). The use of an e-pager and possibly an additional meter allows for limitation of the period of use; the reduced grid fee is then billed.
