Another day and another opportunity to test, learn and charge some batteries.
During the tests, manufacturers of electric vehicles and charging stations check:
✔ interoperability and compatibility between charging stations and electric vehicles.
✔ correct operation of functions, in particular Plug & Charge
✔ compliance with communication standards between charging stations and EV4.
✔ Cybersecurity level in products.
For the current testing teams, the last few days were a great opportunity to verify whether the technologies being developed meet all the requirements and are ready for full cooperation with other systems and products.
