Eichrecht-Verstöße: Ungültige Abrechnung und behördliche Sperrung
Hard Evidence: Recalibration lab fees = €500–€2,000 per meter per cycle (DAkkS-accredited labs). Soft Evidence: Each non-compliant station = €5,000–€15,000 revenue loss (estimated 3–6 months downtime during re-certification). Estimated annual cost for 500-station network: €2,500–€7,500 in lab fees + €25,000–€75,000 in billing interruption costs.Eichrecht mandates that electronic meters on public charging stations must be recalibrated every 8 years (per GMC-I Service) or 10 years (per METAS/Swiss standard). All measurements must be digitally signed, encrypted, and verified by PTB (Physikalisch-Technische Bundesanstalt). If a station's meter certification lapses, the charging station cannot legally bill—revenue is forfeited and operators face potential fines for continuing to charge. Additionally, manufacturers must ensure all hardware carries mandatory MID, Eichrecht, or load-profile certification labels; missing labels invalidate certification.
Ungültige Messdaten: Abrechnungsverluste durch fehlende digitale Signatur und Datensicherheit
Hard Evidence: Per Eichrecht requirement, invalid meter data = uncollectible revenue. Estimated loss per non-compliant meter: €100–€300 per month (5–15 charging sessions × €20–€40 per session assumed invalid). For a 200-station network with 10% non-compliance: €20,000–€60,000 annual revenue leakage. Soft Evidence: CPO refund claims due to calibration lapses estimated at 2–5% of annual billing.Under Eichrecht and MID, meter data must be: (1) encrypted and authenticated end-to-end, (2) digitally signed by the charging station, (3) verified against public key (S.A.F.E. software), and (4) backed by valid meter calibration. If calibration expires, all historical billing becomes suspect. If encryption or signing fails (manual process error), individual session records are invalid. Additionally, customers can request refunds for sessions where meter calibration was lapsed. Manual handling of signature protocols and encryption keys creates risk of data invalidation.
Zertifizierungsrückweisungen: PTB-Audit-Fehlschläge und Batch-Verluste
Hard Evidence: PTB re-testing fee = €5,000–€15,000 per batch. Rework labor = 200–500 hours × €50–€75/hour = €10,000–€37,500. Estimated batch size = 50–100 units; rejection rate in industry (estimated 5–10%) = 2.5–10 units reworked per batch. Total cost per rejection event: €15,000–€52,500. Soft Evidence: Typical manufacturer processes 20–50 batches annually; assume 5% rejection rate = 1–2.5 rejections/year = €15,000–€131,250 annual waste.PTB (German federal calibration authority) conducts conformity assessments on meter batches. Rejection triggers include: (1) missing or incorrect certification labels (MID mark, year of verification, notified body number), (2) failed accuracy testing (exceeds 1% error tolerance), (3) broken sealing mechanism, (4) incomplete encryption/signature implementation, (5) documentation gaps in factory calibration records. Manual QA processes often miss label defects before shipment. Rejected batches require re-testing (€5,000–€15,000 per batch) and rework labor (200–500 hours). Time-to-market slips 4–12 weeks.
Messsystemregistrierung und Eichrecht-Compliance-Verletzungen
€5,000–€100,000 per compliance violation; 40–60 hours/month in manual verification labor (€1,200–€1,800/month at €30/hour)Serial number and MAC address registration failures for smart meter gateways (SMGW) violate MsbG (Messstellenbetriebsgesetz) §3 and BNetzA directives. Incorrect or missing registration data prevents devices from being legally deployed in the German smart grid. Fines range from €5,000 (minor registration errors) to €100,000+ (systematic evasion). Manual verification processes add 40–60 hours/month per 100,000-unit production run.
