Technical notes on charging infrastructure and open platforms.
Practical notes on architecture, OCPP, CPMS, zero-downtime migration, calibration law and data sovereignty in operations.
EV Charging Software: Cloud, On-Premise, or Hybrid?
Cloud, on-premise, or hybrid: an honest comparison of the three deployment models for EV charging software, plus a verifiable vendor-selection checklist.
9 min CPMSCPMS Selection: 12 Criteria That Matter in Tenders
Twelve testable criteria for CPMS selection: protocol substance, operations, billing compliance and exit clauses – with a check for each before signing.
9 min OCPPOCPP 2.0.1 Migration Without Downtime: The Proven Process
An OCPP 2.0.1 migration succeeds without downtime when a broker cleanly separates shadow connection, comparison operation, and group-wise cutover.
9 min OCPPOCPP Broker vs. CPMS: What OCPP Middleware Actually Does
An OCPP broker decouples charge points from backends while a CPMS carries the business logic – keeping the two apart leads to the more stable architecture.
9 min ComplianceGerman Calibration Law in EV Charging 2026: OCMF, Transparency Software, Recalibration
What German calibration law (Eichrecht) requires for public charging: MID-compliant meters, OCMF-signed meter values, verifiable transparency for drivers, and recalibration of existing hardware.
9 min CPMSWhite-Label CPMS: Rent, Buy, or Run It with Source Code?
Whether a white-label CPMS is rented, bought, or operated with source code determines cost, control, and the ability to switch for years to come.
10 min ComplianceISO 15118 and AFIR: What the obligations since January 2026 mean for operators
Since January 2026 the EU requires ISO 15118 for new public AC charging points – combined with the AFIR baseline obligations, this changes procurement, backend and operations for CPOs.
9 min OCPPOCPP 2.1 at a Glance: What Changes and When Upgrading Makes Sense
OCPP 2.1 brings bidirectional charging, DER integration and more robust offline transactions while remaining fully backwards compatible with 2.0.1.
9 min OCPPMulti-Backend Strategy for CPOs: Avoiding Vendor Lock-in
Charge points outlive backend contracts – a multi-backend architecture with an OCPP broker keeps the charging infrastructure backend replaceable.
9 min ComplianceXRechnung and ZUGFeRD for EV Charging: Setting Up B2B Billing Correctly
Germany's e-invoicing mandate turns B2B billing for charging into a data-chain challenge — from signed meter values through CDRs to a valid XRechnung.
9 min EV ChargingWhy cloud-only charging infrastructure is risky
Why cloud-only charging infrastructure is risky: load management, authorization and availability need a resilient edge layer.
11 min OCPPOCPP Broker: when do you really need one?
An OCPP Broker is useful when charge points, backends and operator processes need decoupling.
10 min Edge AIEdge AI in charging sites: 8 use cases
From local troubleshooting to smart charging: where Edge AI creates value first.
12 min Industrial AIPredictive maintenance at the edge
Why predictive maintenance often starts better locally than in a central data lake program.
10 min BrownfieldBrownfield Industrial AI: why data integration is the real bottleneck
Industrial AI rarely starts with perfect data. Success depends on pragmatic OT/IT integration.
11 min CPMSCPMS at the edge: what should run locally and what belongs in the cloud
Robust charging infrastructure separates local operating logic and central platform functions.
10 min ResilienceResilient charging infrastructure through edge and cloud
How charging sites become more robust by combining local intelligence with central platform functions.
