Obligations for charge point operator (CPO) and emobility service providers (EMSP)
/ Verpflichtungen für Ladepunktbetreiber (CPO) und Anbieter von E-Mobilitätsdiensten (EMSP).
Measurement Accuracy Notes According to the Type Examination Certificate
1. Obligations for the Operator of the Charging Station, which must be fulfilled as a necessary prerequisite for
the proper operation of the charging station.
The operator of the charging station is considered the user of the measuring device within the meaning of § 31
of the Measurement and Calibration Act (Mess- und Eichgesetz).
A. The charging station is only considered to be used in accordance with the calibration law if it is not exposed to
environmental conditions other than those for which its type examination certificate was issued. These conditions
are described in the technical documentation accompanying the charging station.
B. The user of this product must include the PK (Public Key) indicated at the charging station for the charging points
when registering the charging points with the Federal Network Agency. Without this registration, operation of the
charging station in compliance with calibration law is not possible. The public key can be found on the rating label
of the product (see "Main parts", "K"), or via remote access (See "Remote access via SSH"). Weblink:

C. The user of this product must ensure that the calibration validity period for the charging station itself is not
exceeded.
D. The user must store the data packets signed and read from the charging station, corresponding to the pagination,
permanently (also) on hardware dedicated to this purpose in his possession ("dedicated storage"). These data
must be made available to authorized third parties (obligation to operate the storage). Furthermore, the user must
permanently retain metering and additional modules removed from the charging station and enable the reading
of the stored calibration logbooks when required by an authorized authority. "Permanently" means that the data
must be stored not only until the conclusion of the business transaction but at least until the expiration of possible
statutory appeal periods for the business transaction. Substitute values may not be formed for billing purposes for
data that is not available.
E. The user of this product must provide measuring value users who receive and use measured values from this
product in business transactions with an electronic version of the operating instructions approved by the
conformity assessment body. In doing so, the user of this product must particularly draw attention to section II
"Obligations for the User of the Measured Values from the Charging Station".
F. The user of this product is subject to the notification requirement according to § 32 MessEG (excerpt): § 32
Notification Requirement (1) Anyone who uses new or renewed measuring devices must notify the authority
responsible under state law no later than six weeks after commissioning.
G. If required by authorized authorities, the user of the measuring device must provide the complete content of the
dedicated local storage or the storage at the CPO with all data packets for the billing period.
H. Remote access via SSH: The product makes available an SSH interface on port 22 to the operator's network. The
interface gives read-only access to audit-related log data, and it is not neccessary for the operator to implement
further access restrictions (aside from those incidentally imposed by the network itself). Username/password:
audit/audit. Available commands:
• cat: Show given log file(s)
• help: Show this list of available commands, or help for a specific command
• ls: List available log files
• read-checksums: Print bootloader checksum
• read-signatures: Print legally relevant software digital signature
• transaction-audit: List transactions and their corresponding signatures
• version: Version number of legally relevant software
Run "help <command>" or "<command> --help" for more information. The scp protocol can be used to
transfer log files from the device.
I. New releases and software updates:
A. Software updates are initiated by CPO through standardized firmware update message complying with OCPP
2.0.1 Standard.
B. The CPO is responsible for informing the control authority about planned software updates and follow
bureaucratic procedures for updating firmware on MID-compliant devices in their country or region.
C. DEFA lists available software, along with the changelogs on the following site:

2. Obligations for the User of the Measured Values from the Charging Station (EMSP)
The user of the measured values must comply with § 33 of the MessEG:
