2. Expanding the ‘real-life-test-charging-plaza’ with 5 DC chargers from GRID

And there’s good news for those driving an EV! Besides the existing 30 AC charging points from We Drive Solar and Floading, Koolen Industries Group Company GRID recently installed 5 DC chargers with each 2 charging points at The Green Box. The total charging capacity on The Green Box is now 40 cars. Charging sessions are managed by intelligent software, enabling load-balancing and tuning with the on-site Solar PV production. The Green Box has its own account for HBE’s, and is accredited with “100% green charging electricity” which adds an extra financial benefit to every kWh charged into an EV. For that reason, the charging rate can be as low as E0,19/kWh. And the EV drivers may park right up front at the main entrance.

The charging plaza at The Green Box with several charging stations from group companies of Koolen Industries is meant to be a live test case for Koolen Industries. Here we learn what customers encounter in practice so that we can serve them as well as possible.
