"eichrechtskonforme Abrechnungsdaten". Billing data that comply with calibration law. The EKA file serves as proof that the selected charging process complies with calibration law. Depending on the type and protocol of the charge point, the proof is available in different forms. For the OCPP/OCMF and LG2WAN protocols, the files are stored in electronic form and can be downloaded for valid charging processes. Proof of other types and protocols must be requested directly from the charge point operator or directly at the charger. 

EMAID

EMAID (also referred to as emobility Contract-ID) stands for "e-Mobility Account Identifier" and is used to uniquely identify your customer. An EMAID consists of the country code (e.g. DE), the provider ID of the e-mobility provider (3 digits), a 9-digit alphanumeric character string (eMA Instance) and a check digit.
