The combination of programmability, light weight design and high efficiency of the DBU-3200 battery chargers resulted in the “Stella Era” achieving optimal charging performance during each short break of the BWSC competition. 

Solar Team Eindhoven’s engineers collaborated with MEAN WELL Europe so that the DBU-3200 battery chargers were configurated to comply with the BWSC regulations.  

MEAN WELL’S “Current Sharing” function enabled three compact 3.2KW DBU-3200 chargers to be connected in parallel to charge the battery of Stella Era in the shortest time possible, and the built-in CAN Bus communication protocol allowed the young engineers to precisely control the charging current at every given moment during the competition. 

According to Daniel Stekelenburg, System Architect Electrical Engineering of Solar Team Eindhoven: “The charger worked perfectly during the challenge and I am certain that our car had the lightest and most efficient charger of all cruiser teams.” 

The sponsorship and technical support offered by MEAN WELL was greatly appreciated by the Solar Team Eindhoven engineers. Mr. Stekelenburg said “We could not have done it without MEAN WELL; the balance of efficiency, light weight and controllability performed exactly what we were looking for”

The winning result proves once more that MEAN WELL brings guaranteed success in battery powered electronics!
