The problem with EV charging infrastructure today
If you've ever tried to integrate an EV charger with a Charge Point Management System (CPMS), you know the pain. OCPP versions proliferate — 1.5, 1.6, 2.0, 2.0.1. Each vendor implements it slightly differently. Each CPMS expects a specific dialect.
The result: integration projects that take months, bespoke translation layers that break with every firmware update, and entire engineering teams dedicated to keeping the plumbing alive.
We've seen this pattern dozens of times across fleets, parking operators, utilities, and eMSPs. It's not a skill issue. The protocol layer is genuinely broken.
What we built
EV Cloud is a network-level OCPP broker that sits between your chargers and your management systems. It handles:
- Protocol translation — OCPP 1.5 ↔ 1.6 ↔ 2.0.1, transparently
- Multi-CPMS routing — route messages to multiple backends simultaneously
- Data ownership — every message is stored and queryable in your own schema
- Lower lock-in pressure — reduce the need to reconfigure chargers when backend strategy changes
You connect once, then shape routing, translation, and downstream integrations as configuration instead of custom charger-by-charger plumbing.
Architecture overview
At its core, EV Cloud is a persistent WebSocket proxy with a stateful message router. Each charger maintains a long-lived connection. Messages are inspected, transformed if needed, and dispatched to the configured upstreams.
We store a full copy of every OCPP exchange — BootNotification, StatusNotification, MeterValues, StartTransaction, everything. This gives you a real-time event stream and a queryable history without any additional instrumentation.

We're starting with OCPP 1.6 and 2.0.1 support. Over the next quarters we're adding:
- Native OCPI integration for eMSP roaming
- Smart charging profiles and load management APIs
- Webhooks and streaming for real-time event processing
