The Bus-Up is kind of a pantograph type, while OppCharge is inversed pantograph. If we end up adding a few other standards in Europe and U.S. plus the wireless charging standards, we feel the industry has a lot homework to do.
Here is one of the first examples of such multi-standard charging station, provided by Heliox in Luxembourg for the Sales-Lentz. One Heliox OC charger allows electric buses to charge with different interfaces: Bus-Up and Oppcharge.
