OCPP orchestrator — charging infrastructure, Pipelet control layer, backends

Live from production

Truck HPC · 299 kW peak · 32 % → 100 %

A real fast-charging session from the Pipelet broker. Every session generates this analysis automatically — no configuration, straight from OCPP messages and MeterValues. Validity, SoC and energy curve, Wh per 1 % SoC, power curve and automatically detected derating events.

Session master data: start, end, duration, meter readings, energy delivered, SoC delta, validity flag, OCPP message count. — Session master data — validity, meter readings, SoC, message count

Line chart: delivered energy in kWh and state of charge in % over time, with the CC→CV transition marked. — Energy & SoC over time — CC→CV transition marked automatically

Chart: watt-hours per 1 percent SoC over time; visible kink at the transition into the constant-voltage phase. — Wh per 1 % SoC — battery cell health indicator

Charging-power curve in kW over time; peak at 299.2 kW, drop at 96 % SoC, taper at session end. — Power curve — 299 kW peak, automatic CV tapering

List of automatically detected derating events: sustained power drops ≥ 15 % from the running peak, classified as CV tail or anomaly. — Derating events — automatically classified (CV tail vs. anomaly)

OCPP Broker is the scalable WebSocket gateway between charge points and your backend. Persistent sessions into the four-digit range per node, digital twin layer with complete state cache, smart proxy for protocol normalisation.

Multi-backend routing per charger, per group, or per site. Zero-downtime migration through parallel operation. Session stabilisation when field communication is unstable — running charging sessions are protected, not aborted.

For integrators and CPOs that need robust OCPP infrastructure without being locked into a monolithic CPMS. The broker runs independently — you combine it with Pipelet CPMS, your own backend, or both in parallel.

What to expect

✓

Digital twin

Complete state cache for every charge point. Query the twin instead of the hardware — faster, more stable, resource-friendly.

✓

Multi-backend routing

Route per charger, per group or per site to different backends. Failover on outage, parallel operation during migration.

✓

Smart proxy

Protocol normalisation between OCPP 1.6 and 2.0.1 — charger-specific quirks are absorbed centrally instead of per CPMS integration.

✓

Session stabilisation

Running charging sessions survive network outages or backend glitches. Reconnect logic, message queue, automatic resync.

Common scenarios

Backend migration across 10,000 chargers

Legacy CPMS and new CPMS run in parallel. The broker routes 1% first, then 10%, then site by site — one click and the group is back on legacy if issues arise.

Heterogeneous hardware

Five manufacturers, five OCPP dialects. The broker normalises, your CPMS never sees the quirks. Tests against a homogeneous protocol.

Frequently asked questions

Is Pipelet available as source code?

Yes. Every module is available as a source-access package — complete with Docker Compose, documentation and an SLA support channel. You can audit, customize and self-host.

Which OCPP versions are supported?

Full OCPP 1.6 and 2.0.1 including Security Profiles, Smart Charging, and ISO 15118 Plug & Charge.

Can I use individual modules only?

Yes. Every module is standalone — you can deploy e.g. just the OCPP Broker as infrastructure and build your own CPMS on top.

What does onboarding look like?

We start with a 30-minute call to scope requirements. After that you get a concrete proposal with modules, timeline and price. Pilot typically live in 4–8 weeks.
