INCIT-EV coordinator CIRCE achieved a significant milestone in electric mobility through a groundbreaking vehicle-to-vehicle (V2V) charging test.

The test took place in CIRCE headquarters in Zaragoza, where a vehicle-to-grid (V2G) test had already been set up by CIRCE’s teams.


V2V electric vehicle charging: the future of electric mobility 

The V2V technology enables electric vehicles to recharge each other without relying extensively on the power grid.

Against the background of an ever-increasing demand in power sometimes leading to grid congestion, this technology is of particular interest. It also makes electric vehicles even more versatile and efficient. An evolution of this technology will allow Roadside Assistance EV Charging Service for Stranded Vehicles and many other possibilities during emergencies or blackouts.

What did the CIRCE test consist of?

As part of CIRCE’s pioneering experiment, a Nissan e-NV200 served as the donor vehicle and discharged its energy, while a Renault Zoe was on the receiving end, benefiting from an off grid recharge.

Let’s dive into the test results!

The graph below illustrates the results of this test.


The green line is proportional to the grid current, which promptly drops to zero when the e-NV200 begins its discharge, showcasing the power of V2G and V2V technology.

The Zoe, on the receiving end, consistently charges at a rate of 15A. When the e-NV200’s power level reaches a certain threshold, it intelligently reduces power output until it reaches zero. If further charging is required, the grid seamlessly steps in to provide the necessary energy.
