EASE Enters its Piloting Phase of Power Protection Devices for EV Chargers
EASE is entering its piloting phase. This new project milestone comes after the development, installation, and testing of two components: The Neutral Fault Protection Relay (NFPR) and the Phase Compensation Module (PCM), designed to significantly improve the stability and safety of electric vehicle (EV) charging systems.
Tackling Grid Instability in EV Infrastructure
As electric vehicle adoption accelerates globally, the demand for better charging infrastructure becomes more pressing. And in this aspect, one of the fundamental requirements of EV charging is a stable and continuous power supply, sometimes challenged by real-world conditions. Electrical anomalies such as neutral faults, overvoltage, and phase loss can offer risks to charging equipment, potentially leading to system failures, costly downtimes, and even safety hazards for the users of the installation.
The EASE project, supported and funded by EIT Urban Mobility, aims to address these vulnerabilities. The newly developed NFPR and PCM devices offer a layer of protection that can isolate and compensate for these faults, ensuring uninterrupted and safe operation of EV chargers.
The Technology Behind EASE: NFPR and PCM
The Neutral Fault Protection Relay (NFPR) is designed to detect the loss or disconnection of the neutral line in a power distribution system. Neutral loss can result in unbalanced voltages across phases, leading to overvoltage in some phases and undervoltage in others, particularly dangerous for sensitive electronics, as EV chargers can be. By isolating affected circuits and triggering safety protocols, the NFPR helps prevent failures and their potential consequences.
The Phase Compensation Module (PCM) complements this protection by managing phase asymmetries and partial power outages. In scenarios where one or more phases are lost or degraded, the PCM can redistribute power loads and balance the remaining phases. This helps the system maintain its performance and ensure operational continuity.
In combination, these devices configure an intelligent fault management system capable of adapting in real-time to fluctuating grid conditions, improving the reliability and lifespan of any EV charging infrastructure.
Piloting and Evaluation
The piloting phase of EASE will be conducted in two different locations, with each pilot running for a duration of six months, during which the NFPR and PCM devices will be integrated into real EV charging stations. To test the devices, varying load and grid conditions will be simulated and monitored. These environments will provide relevant data later used for assessing the effectiveness, adaptability, and performance impact of the EASE solution.
Following the pilot phase, the project will undergo a technical and socio-economic evaluation conducted by CARNET. This assessment will explore not only the technical KPIs defined, but also broader implications for scalability, return on investment, and regulatory integration across European and global EV markets to ensure the later marketing phase for the solution.
Shaping the Future of EV Charging Infrastructure
By integrating advanced protection mechanisms at the hardware level, EASE aims to increase the safety of EV charging infrastructure against any power grid irregularities. This is especially vital as the energy grid becomes more complex due to the rise of decentralized energy resources (e.g., solar, wind) or bidirectional charging.
The success of the project is driven by a consortium of partners, with CARNET leading the technical validation and project management, CERTH overseeing the pilot evaluations and dissemination, CityZone and Oto Parking S.A. coordinating the pilots, and Phasor Ltd, developing and commercializing the developed technology.
This piloting phase marks a crucial step toward the commercial rollout of NFPR and PCM technologies, which promise to set new standards for resilient, smart, and safe EV charging. As urban centres and energy providers seek sustainable mobility solutions, the innovations pioneered by EASE could play a central role in enabling a reliable transition to electric transportation.
