EV Charger Retrofit in Europe: Core Drivers for Charge Point Operators

The most well-known driver is hardware aging. Long-running public chargers face component degradation, wear on connectors, power modules and communication units. Timely part replacement reduces downtime and extends asset service life significantly.

Meanwhile, ISO 15118 upgrade becomes a non-negotiable priority. Supported by SECC modules and PLC communication, ISO 15118 enables seamless Plug & Charge. Driven by the EU AFIR regulation, operators must prepare existing stations to meet new standards, eliminating barriers for modern EVs.

1. OCPP protocol migration: Upgrade legacy OCPP 1.6 to OCPP 2.0.1 to support certificate management, remote firmware OTA and stable ISO 15118 interoperability.
2. Network phase-out: Replace obsolete 2G modems with 4G communication modules to avoid offline charging stations.
3. AFIR compliance updates: Retrofitting for ad-hoc contactless payment, MID-certified metering and DATEX II open data output.
4. V2G readiness: Reserve bidirectional charging capability to participate in grid demand response.
5. Cybersecurity reinforcement: Add encrypted communication to satisfy EU data and network security rules.

6. User experience optimization: Upgrade displays, refresh enclosure protection and unify branding across charging sites.

   
   

Full replacement often brings heavy capital expenditure. Targeted retrofit allows CPOs to align existing fleets with regulatory timelines, support new EV models and prepare for smart energy services.
