Display Screens On The Dc Energy Meter; Invoicing Verification - Bender iONiX Light 25 Wallbox Manual

End charging using the display
In the freecharge mode (i. e. charging without having to pay, which can be set via the configuration interface)
charging can be ended by pressing the "Stop" field on the display.

Display screens on the DC energy meter

On the right-hand side of the DC energy meter display different values are displayed in rotation, with the
values changing every 5 s. What these values refer to can be identified via the codes shown on the left side of
the display in a somewhat smaller font. The following codes are relevant for customers when they are checking
their invoices:
• 1.8.0: Overall current import from the grid (relevant under calibration law)
• 152.8.0: Overall transaction of the energy imported into the vehicle (relevant under calibration law)
• 140.7.0: Line loss resistance (relevant under calibration law )
• 0.9.1: Device time (information)
• 0.9.2: Device date (information)
For the meaning of the remaining codes and all the details on the display and the DC energy meter (among
others the nominal operating conditions), see the information made available online:

The accuracy of the charging device at its delivery point corresponds at least to that of a Class A energy
meter as defined in the Measuring Instruments Directive (see specification on the name plate in chapter
"Designations", page 15).

Invoicing verification

If charging at the DC Wallbox is not only authorised but also billed according to the authorisation, end
customers can rule out that the invoicing data is incorrect.
Currently, invoicing in compliance with calibration regulations is only supported based on energy (kWh).
The verification possible for the customer is based on functions of the DC energy meter used, which has been
approved by the measurement and calibration authorities for this purpose.
In the range between 6.5 A and 65 A the user can carry out charging in compliance with calibration regulations
as defined by the MessEV. The minimum supplied energy quantity for charging in compliance with calibration
regulations is 1 kWh.
The DC energy meter generates electronic signatures for each charging process at least at the start and end of
charging. These signatures include the customer identification, the identification of the DC energy meter, the
current time and the total active energy that has flowed through the DC energy meter since installation.
For reliable verification, the end customer must complete several steps:
1. Before charging begins, it must be ensured that the time stored in the DC energy meter is sufficiently
correct so that the charge can be allocated correctly at the end of an invoicing period. This means that the
day must be correct and the time roughly correct. The time is indicated in the meter's display in rotation
with other information and should be verified by the end user before charging.
2. The signatures for the start and end meter value of each charging process are generated automatically
and require no further interaction from the user.
