CharLynk – OCPP Test Console

CharLynk is a local OCPP 1.6J CSMS testing and debugging tool designed for EV charger development, validation and troubleshooting.

Run an OCPP Central System directly on your Android device and connect compatible EV chargers over your local network — without setting up a separate backend server.

CharLynk is built for developers, QA engineers, integration teams and technicians who need a practical way to inspect charger communication, test OCPP behaviour and troubleshoot issues during development or in the field.

Key features

• Run a local OCPP 1.6J CSMS directly on your device
• Connect and manage compatible EV chargers / wallboxes
• View charger connection and status information
• Inspect live OCPP messages and communication logs
• Monitor MeterValues and charger telemetry
• Manage ID Tags for authorization testing
• Trigger common remote OCPP commands
• Read charger configuration values
• Test charger behaviour without a separate cloud backend
• Use a portable setup for development, QA and field troubleshooting

Local-first testing

CharLynk is designed around a local testing workflow. Core OCPP communication between CharLynk and your charger can remain on your device and local network, making it suitable for bench testing, development environments and field troubleshooting.

CharLynk Pro

CharLynk includes core OCPP testing features, with optional Pro tools for more advanced testing workflows such as additional wallbox support, log export, configuration changes and other advanced OCPP tools.

Who is CharLynk for?

CharLynk is useful for:

• EV charger firmware developers
• QA and validation engineers
