The Solaris Urbino 12 electric is a twelve-meter-long, purely electrically operated battery bus in low-floor design from the Polish commercial vehicle manufacturer Solaris Bus & Coach with electrical equipment from the German company Kiepe Electric . Conceptually comes from the vehicle of the bus type series Urbino .
In the course of various funding projects to test the use of renewable energies in local public transport, the vehicle will be used by several transport companies from 2014 . The first regular service of an Urbino 12 electric took place after introductory test drives on March 27, 2014 in Braunschweig , at the same time this vehicle is the second battery- powered Urbino sold for Klagenfurt after an 8.9 m long and 2.4 m wide midibus .
Together with the battery midibus Urbino 8.9 LE electric and the battery articulated bus Urbino 18 electric , the Urbino 12 electric forms a product range. In 2012 the series received the EBUS Award in the battery bus category.
The Solaris trolleybuses from the Trollino 12 (two-axle solo car), Trollino 15 (three-axle solo car) and Trollino 18 (articulated car) series are also electrically powered .
The Solaris Urbino electric is visually almost identical to the Czech battery bus Škoda Perun , which is also equipped with an Urbino body, but with electrical components from Škoda Electric .
Technology and equipment
Various charging systems are available: A plug-in system for alternating current, in which the charger is located in the vehicle, a plug-in system for direct current with an external charging system, and a non-contact inductive charging system using plates in the vehicle floor. In addition, the battery bus can be equipped with pantographs so that it can be charged with the electrical infrastructure of trolleybuses, for example. In this case, ironing on and off is fully automatic.
It is driven by two asynchronous motors on the rear axle. Both the front and drive axles come in the basic configuration from ZF , as does the Servocom 8098 steering system.
The traction batteries are located in the rear of the vehicle , with lithium-ion batteries being used as standard . Compared to the Urbino basic model, additional weight has been saved on the stainless steel body . Aluminum panels are also used for the sheet metal on the side walls. Under test conditions, the bus achieved a range of 150 km on a full charge.

The vehicle can be ordered with two or three passenger double doors, whereby a single door is also available for the front entry. In the basic configuration, a foldable wheelchair ramp is provided on the second door. The entry widths for the double doors are between 3.2 and 3.4 meters.
For the lighting, the Polish manufacturer relies on energy-saving and low-maintenance LED technology across all vehicles . The control elements on the driver's workstation can optionally be replaced by several touchscreen monitors, but a cockpit with normal displays and push buttons is still available.
With the three vehicles for the üstra Hannover, the model update was also implemented in the battery bus version of the Urbino , which is reflected in the significantly more angular exterior design.
Locations
In addition to several demonstration vehicles from Solaris, Urbino electric buses are currently in use at the following locations.
Braunschweig
Since March 27, 2014 as part of the grant project EMIL is (e-mobility via inductive charging) , the first Solaris Urbino 12 electric in Lower Saxony Braunschweig in regular service on the heavily traveled around 12 kilometers long ring bus 419 ( Hauptbahnhof → Leonhardsplatz → Jasperallee → Hamburger Straße → Rudolfplatz → John-F.-Kennedy-Platz → Hauptbahnhof). The car is charged without contact using electromagnetic induction charging plates . The Primove inductive charging system used at the stops and in the vehicle comes from Bombardier Transportation . In addition to the corresponding charging stations on the Lindenberg premises of Braunschweiger Verkehrs-GmbH, there are two charging fields in the main station turnaround loop and another plate at the Hamburger Straße stop on the way. Reloading takes place at the main train station during the break times, while on Hamburger Straße reloading takes place for around 30 seconds while passengers are changing. The two-door vehicle was added to the fleet with the number 1401 and was given an exterior design in white with a green banderole that differs from the white and red diesel bus fleet.
During the week, the electric bus operated by Braunschweiger Verkehrs-GmbH initially has two, and since April 14th, three fixed schedule runs that differ from the standard schedule of the line and are shown separately. For the rest of the day, the car will be freely used as a sidecar to the existing diesel bus traffic on the counterclockwise circular line. Line 429 running in the opposite direction (Hauptbahnhof → John-F.-Kennedy-Platz → Rudolfplatz → Hamburger Straße → Jasperallee → Leonhardplatz → Hauptbahnhof) continued to be operated exclusively with diesel vehicles for the time being. Battery buses are now also being used here.
At the end of 2014, the first all-electric articulated buses of the Solaris Urbino 18 electric type were delivered in Braunschweig, which means that Verkehrs-GmbH will also be the first customer for the battery articulated vehicles.
Krakow
Since April 2014, the Kraków Municipal Transport Authority has been using a leased Solaris Urbino 12 electric as a test on line 154, which runs from the Ostseite Central Station to Prądnik Biały. The bus is charged at night in the depot and, according to Solaris, is sufficient for the car to operate all day. The vehicle is equipped with 210 kWh batteries and a charger with an output of 100 kW.
On the basis of the results of the endurance test, the MPK Kraków is to make a decision on purchasing a larger number of electric buses.
Dusseldorf
Two more Urbino 12 electric were handed over to Rheinbahn AG in Düsseldorf on September 26, 2014 , and operations began three days later on September 29. The unit price for the procured vehicles is 700,000 euros. One of the two Rheinbahn battery buses is the 10,000 Solaris produced. The two cars, which have been classified as 9071 and 9072 and assigned to the Benrath depot, are supplied with electricity using a plug-in charging process. To be fully charged, the car must be plugged into the socket for four to six hours. With a fully charged battery, the car can cover around 150 kilometers without further recharging.
The lithium-ion batteries with 210 kilowatt hours and a nominal voltage of 660 volts are housed in the rear of the vehicle, at the point where the engine tower is located in a diesel Urbino . The 160 kW asynchronous electric motor is located under a platform in the area of the rear axle, while the power electronics are housed in roof containers.
The cars are used on the round lines 778/779 ( S-Bahn station Benrath ↔ S-Bahnhof Garath ↔ S-Bahnhof Benrath), for which a charging station has been set up at the common end point in Benrath.
Västerås
A battery bus with a plug-in charging system was ordered from Solaris for use in the Swedish municipality of Västerås . In addition, a multi-module battery with a capacity of 160 kWh is installed, whereby the modules are located both in the rear and on the roof of the car in order to obtain a more favorable axle load. Another special feature is the gas heater installed in the vehicle, which is fed by two pressurized gas cylinders on the vehicle roof. This measure should also reduce the load on the battery when heating.
Dresden
As the Dresdner Verkehrsbetriebe (DVB) announced in July 2014, from 2015 an electrically operated Solaris Urbino 12 will serve the tram connection from Mickten to Übigau , which was destroyed by the 2002 flood in Dresden and which is currently used as line 79 by smaller buses of the transport companies becomes. In order to ensure the charging of the bus, it is given a small piece of its own overhead line at the Mickten endpoint on Drey 30platz, where it can charge its batteries via a five-pole pantograph while it is stationary. At night, charging takes place via a charger at the Trachenberge depot .
The vehicle, a three-door Urbino 12 electric, is painted in the corporate color yellow and carries large-scale advertising for the project in the form of a stylized battery with protons and electrons , which is marketed as the “DVB Streamline”. The output of the electric motor is 160 kilowatts, the storage capacity of the lithium-ion battery is 200 kilowatt hours. The vehicle cost around 400,000 euros, around a third of which was funded by the federal and state governments. The cost of setting up the charging infrastructure came to around 200,000 euros, around half of which is financially supported.
Streamline 79 is part of the federal program "Showcase Electromobility" and is scientifically supported by the TU Dresden .

Warsaw
With the commissioning of a total of ten vehicles, MZK Warszawa has had the largest fleet of Urbino 12 electric to date since spring 2015.
The three-door buses, which are supplied with electricity using plug-in charging, are included in the fleet under numbers 1901–1910 and are mainly used on the Warsaw bus route 222 (Spartańska - Bielańska).
According to MZK, the acquisition costs amounted to around 22 million złoty , which would, however, pay off due to the lower operating costs. The Urbino 12 electric needs around 1.35 kWh to drive one kilometer. The batteries are charged overnight in the depot or by cable between scheduled trips. The plan is to have around 130 electric buses in operation in the Polish capital by 2020.
Berlin
In the summer of 2015 was in Berlin bus route 204 ( Zoologischer Garten ↔ Metro Station Kurfürstendamm ↔ kleistpark ↔ Südkreuz ) equipped for the use of electric buses with the Primove-inductive charging. For this purpose, charging stations were built at the two terminal stops of the 6.1 kilometer long line in the Hertzallee installation behind the Zoo station and on Hildegard-Knef-Platz west of the Südkreuz station.
Solaris, Kiepe and Bombardier delivered four appropriately equipped Urbino 12 electric vehicles to the Berliner Verkehrsbetriebe (BVG) for the project , which were presented to the public on July 1, 2015 at the BVG depot Indira-Gandhi-Straße . The cars in the yellow BVG design, which are designed for a maximum speed of 65 km / h, have two double passenger doors, 34 seats and 40 standing places and are lined up in the fleet with the numbers 1685–1688. The electric motor of the vehicles has an output of 160 kW, the necessary energy is stored in a 90 kWh battery, which is located on the roof.
Oberhausen
With the timetable change on October 4, 2015, two purely electric buses went on line at STOAG . The project jointly implemented by VRR and STOAG, in which the existing direct voltage infrastructure of the Oberhausen public transport route is used for fast charging of electric buses, is entering the final phase. The charging stations that supply the buses' batteries with electricity were completed at the end of July 2015 at Sterkrade train station and Neumarkt. While the energy is tapped directly from the tram overhead line at the station, the charging current for the Neumarkt station comes directly from the substation there.
The two Urbino 12 Electric are on line 962 (Sterkrade train station ↔ Alsfeld ↔ Königshardt ↔ Kleekamp ) with a circuit length of 15.6 km and the line 966 (Neumarkt / Sterkrade train station ↔ Schloss Oberhausen ↔ Oberhausen main station ) with a line length of 13, 3 km are used. Both routes are operated every 60 minutes, so that only one vehicle is required at a time. After each cycle, the battery of the e-buses is charged at the terminus within ten minutes.
On August 5, 2015, the two electric vehicles from Solaris arrived with the low-loader at the depot of the public utility company. The buses are charged in Oberhausen using Schunk pantographs on the roof. The energy is stored in a five-module traction battery from the manufacturer IMPACT with a total capacity of 200 kWh. A MEDCOM traction inverter with 600 V direct current serves as the converter. Two asynchronous motors with 110 kW each, installed on an AVE rear axle from ZF, provide the drive. The 18-ton buses can reach a top speed of 75 km / h and have 42 standing and 28 seats, including four folding seats.
Hanover
In Lower Saxony Hanover are from the üstra electric three Urbino 12 for use on the Experience Line marketed ring line 100/200 (August Holweg Square ↔ Lindener marketplace ↔ Glocksee ↔ King Platz ↔ Vahrenwalder Platz ↔ Listerplatz ↔ Kröpcke ↔ Aegidientorplatz ↔ August- Holweg-Platz), which connects the sights of the state capital with each other over around 16 kilometers with 42 stops.
The vehicles are driven by two electric motors close to the wheel hub, each with 60 kW continuous output on the ZF rear axle, which are supplied with electricity by lithium titanate batteries with a capacity of 120 kWh. The wagons are equipped with a roof loading system to enable all-day operation without having to stay in the depot. Power is supplied via a 4- or 5-pole Schunk pantograph installed on the roof of the vehicle. Charging for one lap in regular service takes four to six minutes, depending on the time of year, at the final stop at August-Holweg-Platz , where the necessary infrastructure will be created in 2014/2015 in the form of an external 450 kW charger. A full charge can be carried out in around 18 minutes. The mast that protrudes above the bus stop with a mount for the pantograph will be integrated into a new bus stop building to be built. The energy required for the charging station is ensured by the power supply for the tram. Around 400,000 euros are being invested in the redesign of the bus stop system. At night, charging is carried out at the depot via a plug-in connection.
The three twelve-meter-long electric buses will be delivered in the new Urbino design, which was presented at InnoTrans 2014 in Berlin. Passengers can be changed via three double doors. There is a total of 40 standing and 29 seated passengers in the car. Commissioning was planned for April 5, 2016.
Hamburg

Also in the new Solaris vehicle design, three Urbino 12 electric were delivered for Hamburger Hochbahn in 2016 . The vehicles will be used on the innovation line 109 (since December 2019 Metrobus line 19 Hauptbahnhof - U Alsterdorf ), where the Urbino 18 electric articulated version is already being used in addition to various other vehicles with low-emission or zero-emission drive concepts from Mercedes-Benz and Volvo .
These battery buses are charged at the charging stations at the terminal stops already used by the other vehicles on the innovation line. For this purpose, the stations are equipped with a single-arm pantograph that is attached transversely to the direction of travel and that is lowered onto a corresponding strip in the front roof area of the bus during the break.
The approximately 12-meter-long cars are equipped with three double doors for quick passenger changes.
The presentation in Hamburg took place on August 17, 2016. Such an elevated Solaris was also presented at InnoTrans 2016.
In 2018, ten buses of the Solaris Urbino 12 model were ordered for the planned changeover of the public transport bus fleet in Hamburg to exclusively electric buses, two of which will be used from autumn 2018. The acquisition costs per model are approx. 600,000 euros
Frankfurt
With the timetable change on December 9, 2018, five Urbino 12 electric will be used on bus line 75 ( U Bockenheimer Warte - Uni-Campus Westend - U Bockenheimer Warte) in Frankfurt am Main, making the line a pure electric bus line. With a purchase price of 500,000 euros, an electric bus is roughly twice as expensive as one with a diesel engine. There are also costs for the infrastructure. The ICB has spent 1.9 million euros on vehicles and chargers, with the state of Hesse contributing around 760,000 euros. Using the buses saves around 200 tons of carbon dioxide and 640 kilograms of nitrogen per year. According to Lord Mayor Peter Feldmann, all local public transport in Frankfurt should be provided without local pollutant emissions by 2030.
Milan
In July 2019, a framework agreement was signed with the Milan-based transport company ATM for up to 250 vehicles, which are to be delivered by 2030. The first tranche includes the delivery of 40 vehicles, which is scheduled to begin in June 2020. 25 e-buses are already in use.
Freiburg
Two Urbino 12 electric vehicles have been in pilot operation at Freiburger Verkehrs AG since February 2020 . At the Europaplatz terminus, the buses can be charged with 150 kilowatts. The fast charging station is supplied from the overhead line network of the city railway.
