Proterra EV Bus have different system

At the upcoming 65th IAA Commercial Vehicles (25. September – 02. October 2014) in Hannover, Germany, Opbrid will present a new way to charge electric trucks - the Trůkbaar.

This is an automatic fast charging system compatible with the standards-based Opbrid Bůsbaar V3 for buses.

In this concept, the pantograph lowers from the curbside station and has 4 contacts to safely provide 650 kW of power (IEC61851-23/24 CCS based). Enough to quick charge in a few minutes and to eliminate the need for a large battery pack.

Opbrid Trůkbaar and Bůsbaar V3 will be on display at the IAA 2014 in Hall 13, Stand F12.

"The Opbrid Trůkbaar and Bůsbaar V3 are designed for ultra high power mode 4 DC charging, up to 650kW. This amount of power transfer uses safe and reliable conductive technology transferred from the European electric rail industry by our partner Furrer+Frey, with over 90 years of experience in high power transfer to locomotives. This amount of power transfer enables scenarios such as super short charge stops and 24 hour operation. Since the Opbrid Trůkbaar and Bůsbaar are 100% compatible, cities can leverage their investment in bus chargers by also using them for rubbish collection, delivery vehicles and street cleaners. Vehicles of various heights can charge at the same station due to the large vertical working range of the charging station."

"The new design of the Opbrid Trůkbaar and Bůsbaar V3 also liberates designers to create curbside charging stations that blend into existing streetscapes, or that stand out as elegantly sculptured street furniture. This is because the overhead pantograph is compact and hidden underneath a weatherproof cover. This means that the mounting post as well as the weatherproof cover can be almost any shape imaginable, giving designers unlimited freedom."

"Of course, safety is our utmost concern, so the Opbrid Trůkbaar and Bůsbaar V3 have been designed to conform to IEC and ISO standards for high power DC charging, with 4 contacts, correct contact sequence, and built-in verification of contact surface before charging. The parking tolerance is quite broad and reliable due to our years of experience making bus fast charging stations. An optional insulating cover for the on-vehicle part is available to add an additional layer of safety. The station retracts upward to over 4.5 meters when not charging to fulfill traffic regulations."
