We’ve linked up with comemso to help you master the complexity of EV charging. V2G Clarity’s compliance Testing-as-a-Service for OCPP 2.0.1 is being offered alongside comemso’s testing and simulation suite (including EV simulation and grid emulator) for 15118 compliance tests to help you make your EV Chargers future-proof. Our tools will help end the interoperability issues that arise from malfunctioning communication protocol implementation. V2G Clarity’s solution is a cloud-based OCPP 2.0.1 compliance testing tool for both charging station (CS) and charging station management system (CSMS) vendors and it will increase interoperability across the e-mobility market. This is a win-win for all CS and CSMS vendors and, ultimately, the end-user, who will receive a seamless charging experience.
In September 2020, I presented our OCPP 2.0.1 Compliance Testing-as-a-Service solution at Hubject's E-Mobility Start-Up Award during the InterCharge Network Conference (ICNC 20) in Berlin. Here is the video from the live presentation on stage, followed by a Q&A session with the jury.
With OCPP 2.0.1 and the new device model concept, a station can automatically describe its full layout and capabilities to the cloud-based CSMS. This allows for plug-and-play installation of a charging station. It also lets the CSMS read and control any component remotely.

The Open Charge Alliance is the official body that specifies OCPP 2.0.1 and defines a set of certification profiles. Each profile tests a certain set of functionalities. Depending on the functionality of your charger or CSMS, you might want to certify for either a subset or all of these profiles.

Scotti stands for Simple Compliance Testing Tool for Interoperability.
Efficient XML Interchange (EXI) is a very compact representation of XML. All ISO 15118 messages are defined in XML. EXI improves serialisation and parsing speed on embedded devices (like an EV and a charging station controller) and allows more efficient use of memory and battery life, compared to standard (textual) XML.
The Message Queuing Telemetry Transport (MQTT) is a lightweight, publish-subscribe network protocol that transports messages between devices.
A CSMS is a cloud-based management system operated by the company that is managing the charging stations. A charging station connects to a CSMS using OCPP (Open Charge Point Protocol).
Automated Connection Device (ACD), a conductive charging concept that doesn't require a person to plug in the charging cable. A first implementation is ACD-P, where 'P' stands for 'pantograph' charging of buses.
Power line communication, a communication technology that enables sending data over existing power cables.
Signal Level Attenuation Characterisation (SLAC) is based on power line communication (specifically HomePlug Green PHY) and is a protocol to establish the data link between the EV and the charging station via the charging cable.
Charge Point Operator, the entity monitoring and managing an EV charger network.
