Description of the load management solution in the metering concept of a ZEV / tenant electricity property​

The load management of the Pico charging station is based on the smart-me meter hardware. This hardware can be used directly as reference points.

If a third-party meter installation is already in place, load management for Picos can also be handled by third-party software instead of the smart-me multilevel load management. You can find more information on this below under "Extended information".

Advantages of smart-me load management:

  • No additional metering hardware required

  • Same manufacturer for the metering hardware and the charging station: top compatibility and reliability

  • Multi-stage, dynamically controlled load management: minimal power losses and high availability

  • Centrally controlled load shedding for the entire installation

  • Solar optimization function optimized for the site or the building

  • Charging group prioritization and passive peak load reduction

Hardware points functionally required for comprehensive load management in a ZEV / tenant electricity setup with smart-me hardware (red arrows):

  • 2x building meter (Telstar 80A or Telstar CT) - Solar optimization point, required for distributing capacity within the site.

  • Optional but recommended: 2x e-mobility meter (Telstar 80A or Telstar CT) - Reference when several charging groups are connected to one outgoing circuit and share its capacity. - Billing measurement for losses and standby energy - Other consumers that are not Pico charging stations can also be taken into account, e.g. garage lighting, sockets, etc.

  • Optional but strongly recommended: 1x site meter (Telstar 80A or Telstar CT) - If one already exists in the ZEV, this point can be taken into account. If there is no site meter, it can be mapped virtually.

Billing of e-mobility in the ZEV (association for own consumption) / tenant electricity​

Billing can be done in various ways, each with its specific advantages and disadvantages:

  • Billing with a single-tariff or multi-tariff system in the ZEV with smart-me Billing, either separately or together with the apartment consumption.

  • Billing with a single-tariff system using the post-payment method and the eCarUp backend.

  • Billing with a single tariff using highly automated credit card billing via the eCarUp backend.
