Measuring accuracy notes in accordance with the type examination certificate
Only applies to the products EVCB-LB-3AC-ECC-10 / EVCB-3AC-ECC-10
I Requirements for the operator of the product, who must fulfill them as a necessary condition for intended operation
In the meaning of Section 31, Measurement and Verification Act (MessEG), the operator of the charger (of the product) is the user of the measuring device.
The charger is only considered to be used as intended by and in compliance with the calibration regulations only if the ambient conditions in the meter installed in it are the same as the ambient conditions for which its type examination certificate was granted.
When registering the charge points with the Federal Network Agency using the registration form, the user of the product must also register the port number specified for the charge points on the charger. Without this registration, operation of the charger in compliance with the calibration regulations is not possible. The required information about registration and the registration form are available under the following external link: https://www.bundesnetzagentur.de/DE/Sachgebiete/ElektrizitaetundGas/Unternehmen_Institutionen/E-Mobilitaet/Ladep_Form/StartNEU/node.html Anzeige_Ladepunkte_node.html.
A quick reference guide for the operator of public charge points is also available under this link: https://www.bundesnetzagentur.de/SharedDocs/Downloads/DE/Sachgebiete/Energie/Unternehmen_Institutionen/E_Mobilitaet/Leitfaden.pdf?__blob=publicationFile&v=6.The user must ensure that the calibration validity periods for the components in the charger and the charger itself are not exceeded.
The user of the product must ensure that the chargers are decommissioned promptly if operation in compliance with the calibration regulations is no longer possible due to malfunction or error indicators in the display of the calibration-relevant human-machine interface. The catalog of malfunction and error messages in the operating manual must be observed.
The user of the product must make the data packets signed and read out from the charger - seamlessly, corresponding to the pagination, and permanently, (also) saved on the hardware dedicated to this purpose (dedicated memory) in the possession of the user - available to authorized third parties (operating obligation of the storage system). "Permanently" means that the data are not only saved until the business transaction has been completed. Instead, they must be saved at least until the expiration of any statutory periods of appeal for the business transaction. Substitute values may not be created for non-existent data.
The user of the product must provide the measured values from this product that they receive and use in the course of business to measured value users in an operating manual approved by the CSA in electronic form. In particular, the user of this product must point out no. II "Requirements for the user of the measured values from the charger."
The user of the product is subject to the notification requirements pursuant to Art. 32 MessEG (excerpt): Art. 32 Notification requirement "(1) Those who use new or reconditioned measuring device must notify the authorities responsible in accordance with national law 6 weeks after commissioning at the latest...".
Insofar as the authorized authorities consider it necessary, the measuring device user must provide the entire contents of the dedicated local memory or the memory at the CPO (charge point operator) with all data packets from the billing period.
II Requirements for the user of the measured values from the charger (e-mobility service provider (EMSP))
The user of the measured values must observe Art. 33 MessEG:
§ 33 MessEG (quote)
§ 33 Requirements for the use of measured values
(1) Values for measured variables may only be listed or used in the course of business or officially, or for measurements in the public interest, if a measuring device was used as intended to determine them and the values can be traced back to the respective measurement result insofar as the ordinance in accordance with Art. 41 (2) does not contain different stipulations. Other federal regulations adopted for similar protective purposes continue to be applicable.
(2) To the best of their ability, measured value users must make sure that the measuring device fulfills the statutory requirements and must have the person using the measuring device confirm that they fulfill their obligations.
(3) The measured value user must
ensure that the measured values listed in bills based on measured values can be easily understood by the recipient of the bills and
provide suitable aids for the purposes listed in no. 1 if necessary.
For users of measured values, this stipulation results in the specific following obligations of measured valued use that is in compliance with the calibration regulations:
The contract between the EMSP (e-mobility service provider) and the customer must clearly stipulate that the supply of electrical energy is the exclusive subject of the contract: it is not the charging service duration.
The timestamps on the measured values originate in a clock on the charger that is not certified in accordance with MessEG. For this reason, they must not be used to tarify the measured values.
The EMSP must ensure that the sale of the e-mobility service takes place via chargers that enable the ongoing charging process to be observed, insofar as there is no corresponding local display on the charger. At the beginning and end of a charging session at least, trustworthy measured values in compliance with the calibration regulations must be available to the customer.
After measurement is completed and at the time of billing at the latest, the EMSP must automatically provide the billing-relevant data packet, including the signature, (e.g., by storing its email address on a website) to the customer as a data file. As long as the customer did not expressly opt out, this must be done in a way that enables the data to be checked for authenticity using transparency and display software. The data can be provided via channels that have not been verified as compliant with the calibration regulations.
The EMSP must provide the customer with the transparency and display software affiliated with the charger for verifying the authenticity of the data packets.
The EMSP must be able to show with conclusive proof which means of identification was used to initiate the charging process affiliated with a specific measured value. In other words, the EMSP must be able to document that each business transaction and billed measured value was correctly matched to the personal identification data. The EMSP must inform the customer about this obligation in the appropriate form.
The EMSP many only use value for purposes of billing that are present in a dedicated memory in the charger and/or the memory of the CPO. Substitute values may not be created for billing purposes.
Through a corresponding agreement with the operator of the charger, the EMSP must ensure that the data packages used for billing purposes are saved for a period that is long enough to enable the associated business transactions to be fully completed.
In the case of justified requirements notification for the purpose of carrying out calibration, results verification and measures for monitoring use, the EMSP must facilitate the authentication of the examples of the products used by the EMSP associated with this operating manual.
All obligations listed above are applicable to the EMSP as the measured value user in the meaning of Art. 33 MessEG, even if the EMSP procures the measured values from the charger via a roaming service provider.
The EMSP must ensure that the customer receives all the information necessary for the receipt of their permanent documentation. For this reason, the website, billing amount and the data of the charging process must be listed on the credit card bill or as the purpose of the account debit in the case of selective charging.
If this necessary information is missing, this is not a case of intended use of the measuring device.If selective charging is used, the EMSP must clearly indicate to the customer how to display the price per unit stored in the data array to the customer in plain text.
