Learn more about the technical aspects of smart charging and vehicle-to-grid (V2G) charging communication
I was invited to a webinar that Newcastle University hosted in conjunction with The Alan Turing Institute in London. We covered many topics related to ISO 15118 and its development, including:
Update to the video: On the presentation slides, TLS (Transport Layer Security) was mistakenly located on the ISO/OSI layer 4 (transport layer), although it should have been placed on the session layer above (layer 5).
An e-book for beginners and experts alike. Reduces the steep learning curve of ISO 15118 by providing a comprehensive and easy-to-understand access to the Vehicle-to-Grid communication protocol. Written by our founder, one of the few co-authors of ISO 15118, this e-book has fast become standard literature in the industry.
Get an extract from each chapter to see the quality and in-depth information you’ll get in the full e-book. The ISO 15118 Manual definitely helps you grow your expertise and positioning in the e-mobility market.

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.
Sara stands for Station Analytics and Remote Administration
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.
Continuous Integration / Continuous Deployment (CI/CD)
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.
