Due to the epidemic situation, the premiere of Urbino 15 LE electric was held online, on 20 October 2020. The new Solaris bus model was equipped, among others, with the SiC propulsion system manufactured by Medcom. Its use makes it possible to reduce energy consumption by up to 13% compared to the leading technologies used to date.
Solaris Urbino 15 LE electric was developed with Scandinavian transport operators in mind, which is why it is intended for both urban and intercity passenger transport. Longer journeys are possible, among others, thanks to the propulsion system supplied by Medcom, comprising a 300 kW traction inverter, a static converter 3x400V 50 Hz with the power of 30 kVA and 24V with the power of 12kW, as well as high voltage switchgear.
The use of the silicon carbide technology contributes to significant limitation of energy losses in the propulsion. In the case of the new Solaris, the gain is twofold, because the propulsion system handles the start-up and regenerative breaking. Thanks to the use of this technology, the Urbino 15 LE electric model meets the “Bus Nordic” and the so-called Scandinavian package standards in effect in the target market.
“We are happy we had the chance to participate in the development of the first Polish bus combining urban and intercity transport options. The new electric bus was manufactured as a demonstration model and was equipped with a number of convenient features, so that potential customers may familiarize themselves with all the available variants. A particularly important parameter of this vehicle is its high energy efficiency, which was possible to achieve thanks to the use of state-of-the-art power electronics manufactured in the silicon carbide technology. Tests carried out according to the SORT criteria on a similar motor in a 12-meter vehicle have already shown a reduction in energy consumption by 13% compared to the technologies used to date. Additionally, Urbino 15 LE electric was fitted with a special braking resistor supplied by Medcom, enabling class II certification – for extraurban buses. This solution was also developed and manufactured especially for the purpose of this project,” says Joanna Nichthauser, Marketing Director at Medcom.
