§ 33 (Requirements for using measured values)
1. Values for measured variables may only be specified or used in business or official traffic or
for measurements in the public interest if a measuring device was used as intended for
their determination and the values can be traced back to the respective measurement
result, as far as in the ordinance according to § 41 number 2 nothing else is determined.
Other federal regulations that serve comparable protection purposes continue to apply.
2. Anyone who uses measured values must ensure, within the scope of their possibilities, that
the measuring device fulfills the legal requirements and has to be confirmed by the person
using the measuring device that they are fulfilling their obligations.
Anyone who uses measured values has
1. to ensure that invoices, insofar as they are based on measured values, can be easily
understood by the person for whom the invoices are intended for checking the measured
values given and)
2. If necessary, provide suitable aids for the purposes mentioned in number 1.
For the user of the measured values, this regulation gives rise to the following specific obligations
for the use of measured values in accordance with calibration law:)
3. The contract between EMSP and the customer must clearly stipulate that only the delivery
of electrical energy and not the duration of the charging service is the subject of the
contract.
4. The time stamps on the measured values come from a clock in the charging device that is
not certified in accordance with measurement and calibration law. They must therefore not
be used to rate the measured values
5. EMSP must ensure that the e-mobility service is sold by means of charging devices that
enable the ongoing charging process to be monitored if there is no corresponding local
display on the charging device. At least at the beginning and end of a charging session, the
measured values must be available to the customer in a trustworthy manner under
calibration law.
6. The EMSP must provide the customer with the billing-relevant data packages including
signature as a data file at the time of invoicing in such a way that they can be checked for
authenticity using the transparency and display software. They can be made available via
channels that have not been verified under calibration law.
7. The EMSP must make available to the customer the transparency and display software
belonging to the charging device for checking the data packets for integrity.
8. The EMSP must be able to show in a verifiable manner which means of identification was
used to initiate the charging process associated with a specific measured value. This
means that he must be able to prove for every business transaction and measured value
billed that he has correctly assigned the personal identification data. The EMSP has to
inform its customers about this obligation in an appropriate form.
9. The EMSP may only use values for billing purposes that are available in any dedicated
memory in the charging device and / or the memory of the operator of the charging device.
Substitute values may not be created for billing purposes.
