As the EU is transitioning to a sustainable and low-carbon economy; decarbonisation of transport is at the centre of this transition, with electric vehicles (EV) leading the change. Not only is this creating a new energy dependency but it is also important to note that EV chargers require a stable power supply to function effectively, but power grid failures such as neutral-loss failure, overvoltage, and phase loss can disrupt charging and also damage the equipment. Current solutions do not adequately address these issues.
The EASE project tests an innovation that offers protection and charging continuity for EV chargers by combining two patented devices: the Neutral Fault Protection Relay (NFPR) and the Phase Compensation Module (PCM). This solution ensures safety and reliability while charging, enhancing the continuity and lifespan of the chargers. The EASE project will validate this solution at select EV charging stations in two different contexts: a Business Park in Tel Aviv and public parking infrastructure in Thessaloniki.

EV charging providers, as parking owners, main electrical disturbances are phase loss and over/under-voltage. These issues are found out later, when the car was supposed to be charged and is not charged, or charged only partially, becoming an income reduction for service providers.
Phasor solutions is activated in case of phase loss to assure charging continuity.
During the project we expect to mitigate grid disturbances and avoid energy waste. Ten end users will be involved in the project and five grid disturbances will be mitigated.
