Ungültige Messdaten: Abrechnungsverluste durch fehlende digitale Signatur und Datensicherheit
Definition
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.
Key Findings
- Financial Impact: 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.
- Frequency: Ongoing; peaks when calibration certification expires or data security protocols fail.
- Root Cause: Manual oversight of meter calibration status; lack of automated data validation; weak encryption key management; missing audit trail for digital signatures; delayed detection of expired certificates.
