That’s why Krakow uses one charging solution for both day and night
Krakow is committed to clean air and is investing in electric mobility in public transport like no other major Polish city. The first electric buses have already been operating in the city since 2014. In 2021, 50 more vehicles have been added, transporting passengers in the area of Krakow where the highest levels of air pollution are recorded (see: cleantechnica.com). But the expansion of the e-bus fleet presented the city with a challenge.
When it comes to electromobility, Krakow plays a pioneering role in Poland. The municipality was the first major city to withdraw all buses with Euro 4 engines and older from service and invest in the first electric buses (see: cleantechnica.com). At the time, the city relied on fast charging on the line and had its small test fleet equipped with roof-mounted pantographs from Schunk.
Roof-mounted pantographs work according to the bus-up principle. This means that the bus stops under a charging station and extends the pantograph mounted on the roof. This automatically connects to the charging station and charges the battery.
Charging stations of this type were installed at various terminal stops and in the city’s depots and were designed to charge the batteries quickly. At that time, overnight charging could still be realized by a plug-in solution in the depot.
In the meantime, however, the requirements have changed. Now, almost 80 electric buses require an efficient overnight charging solution. In other words, no one wants to fiddle with plugs here anymore. And it’s not necessary either. Because: Krakow has not only invested in 50 new electric buses with roof-mounted current collectors, but also in corresponding contact systems for automated charging in the depot. This means that all electric buses on Krakow’s roads can now be charged quickly on the route with high charging power and slowly overnight with low charging power.
“We see here a typical challenge of transport companies with a growing fleet: How do I implement overnight charging in the future - via a plug-in solution or with pantographs?”
In his view, automated overnight charging using pantographs offers decisive advantages.
In addition,
“For us as a manufacturer of charging solutions, it's great to see how Krakow is investing in electromobility in public transport, how the infrastructure is growing historically and how our system has become established.”
But it’s not just in Krakow that Schunk technology has proven its worth in helping electric buses get new energy. Worldwide, electric buses equipped with pantographs from Central Hesse operate in more than 100 cities in 25 countries. Thereby, “Smart Charging” solutions for the most diverse customer requirements are in use.
