Review of blockchain technology in smart grids ecosystems

Three years ago, Trialog studied the applicability of blockchain technology in smart grids through a Trilab demonstrator. This focussed on the use of blockchain to track the charging sessions of electric vehicles, and process the transactions through the use of smart contracts. Since then, re-using this technology was considered in the scope of the [...]

A Digital Twin Demonstration for EV Charging Stations Within The TriLab

While digital twins constitute an integral facet of an emerging technological landscape whose potential continues to grow, they largely elude recognition within the general public. Even amid the most adept technology enthusiasts, digital twins persist in kindling an aura of enigma. Nonetheless, as the global sphere undergoes transformation, so too does the dissemination of [...]

Electrifying Momentum: OCPP 2.0.1 and the Unfolding E-Mobility Evolution

Since its release in April 2020, OCPP 2.0.1 has gained significant attention as the latest version of the Open Charge Point Protocol (OCPP) maintained by the Open Charge Alliance (OCA). OCPP is the protocol responsible for handling communication between a charging station and its backend management, such as a charging station management system (CSMS). [...]

Advancing Towards Wisdom: A Vision and Need for Interoperability

A simplified approach to advancing grid technology involves design with built-in compatibility to ensure seamless communication. However, building different complex systems (e.g., intelligent transport systems, smart grid systems, smart city systems) and interfaces that work well together is challenging. There are many rules and methods that must be followed, which can cause confusion among [...]

IoT Robotics-based Semantic Interoperability Applied to Smart Healthcare and Emotional Well-Being

This article is part of the Trialog blog series on IoT and Interoperability, begun in September 2020 with the first article focusing on ‘IoT Systems and Interoperability’.  Trialog is conducting projects in the ‘Social and Health Care’ domain. Specifically, Trialog served as the coordinator of the European ACCRA (Agile Co-Creation of Robots for Ageing) [...]

Implementing smart grids in African contexts

Introduction With a high potential for renewable energy production, an economy in expansion and areas disconnected from the electricity grid, Africa has some of the best opportunities to experiment with smart grid technologies. The EU research and innovation project ENERGICA investigates these opportunities through three pilots, in Kenya, Madagascar and Sierra Leone. In this [...]

ISO 15118-20, not only a further step towards bidirectional charging

The ISO 15118-20 standard, published in April 2022, extends the ISO 15118-2 standard released in 2014. In addition to improving the functionalities covered by ISO 15118-2 (AC and DC charging, Plug and Charge, Smart Charging), ISO 15118-20 expands the range of possibilities and use cases by specifying bidirectional, wireless and pantograph charging. As a [...]

Technical overview of G3-PLC Hybrid PLC&RF

Introduction Since its first public specification in 2015 and its continuous development by the G3-PLC Alliance, the G3-PLC technology has been broadly deployed all over the world for smart metering and other applications. One of the feedbacks from large roll-out was that, while connectivity to 99% of devices was possible, achieving consistent connectivity to [...]

Proof of concept: Augmented reality for electric vehicles

Augmented reality allows us to enrich reality with virtual elements. Information is superimposed, and 3D objects complete the reality to obtain an augmented version. This technology has applications in many different fields, such as video games, museum visits and industrial processes. The communication between electric vehicles and charging stations is part of Trialog's expertise, [...]

Geographical islands: A laboratory for smart grids

Based on the European projects GIFT and MAESHA Geographical islands are particularly relevant in the study of energy management, as they are one of the very few areas where the electricity system almost fully operates as a closed-loop system. Owing to few or no interactions with external grids that would facilitate network operation and [...]
