OCPP 1.6J Charge Point Simulator Documentation

mockpoint is a deterministic OCPP 1.6J charge point simulator designed for testing CSMS implementations. It connects to your CSMS over WebSocket, executes scenario-defined OCPP message flows, and reports results with exit codes suitable for CI pipelines. Written in Rust for performance and reliability.

What is ./mockpoint?

./mockpoint is designed for CSMS developers, QA engineers, and system integrators who need to test EV charging infrastructure with deterministic, reproducible results in automated workflows.

Key Features

Single binary — no dependencies, built on Tokio runtime for high concurrency
Cross-platform — runs on Windows, Linux, and macOS (Intel & Apple Silicon)
for defining test flows
for reproducible tests
Scales to hundreds of concurrent charge points depending on license tier and hardware

⚠️ Scope Notice

Smart Charging, Firmware Management, and OCPP 2.x are intentionally out of scope. mockpoint focuses on core OCPP 1.6J message flows for CSMS testing—these exclusions are deliberate design decisions, not missing features. See for details.
