The Solaris Urbino 18 electric is a battery - articulated bus with a length of 18 meters, of the Polish utility vehicle manufacturer Solaris Bus & Coach is manufactured. Conceptually, the vehicle belongs to the Urbino line of buses . The vehicle is also offered as the Urbino 18.75 electric with a slightly extended car body .
In the course of various funding projects for testing the use of regenerative energies in local public transport , the vehicle has been used in regular transport by Braunschweiger Verkehrs-GmbH and Hamburger Hochbahn since the end of 2014 .
Together with the battery midibus Urbino 8.9 LE electric and the battery solo bus Urbino 12 electric , the Urbino 18 electric forms a product range.
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 .
Technology and equipment
The articulated buses are also an inductive charging system of the type Bombardier Primove offered. This enables the use of a relatively small traction battery , which is housed on the roof of the trailer and has a capacity of 90 kWh. Lithium-ion batteries are used as standard . A fuel cell solution from Ballard with 101 kW is also being sought in the medium term, with the main load then being carried by a lithium iron phosphate traction battery with 120 kWh.
The articulated bus is driven by a 240 kW asynchronous motor in the trailer. The energy management and electrical equipment for the cars is supplied by Kiepe Electric .
The axles and the steering system of the Servocom type are supplied in the basic configuration by ZF . The front axle is implemented as a standard independent wheel suspension , a rigid axle is also available as an option. An electronic brake system (EBS) with anti-lock braking system and traction control also works in the vehicle . 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.
The Urbino 18 electric is optionally available with three or four passenger double doors, whereby a single door can also be implemented at the front entrance. Depending on the equipment, the car has up to 51 seats.
For the lighting, the Polish manufacturer relies on energy-saving and low-maintenance LED technology across all vehicles . The controls on the driver's workstation were replaced by several touchscreen monitors.
Locations
Braunschweig
As with the 12-meter version of the Solaris Urbino electric, Braunschweiger Verkehrs-GmbH was also the first customer for the 18-meter-long articulated battery bus. As part of the EMIL ( electromobility by means of inductive charging ) funding project, four Urbino 18 electric were delivered to Braunschweig at the end of 2014. The delivery of two more vehicles was planned by 2016. Initially, it was planned to use the M19 ring bus, which, starting from Braunschweig main station, follows the Wilhelminian city ring counter-clockwise. This was converted accordingly for operation with the Primove inductive charging system: In the turning loop at the main station and about halfway along the route at the Hamburger Straße stop , appropriate charging stations were set up, via which the buses can be supplied with power without contact.
The first articulated trolley was presented to the public from September 23 to 26, 2014 at the InnoTrans in Berlin at the stand of Bombardier Transportation, which is supplying the Primove technology. Commissioning was scheduled for autumn 2014. The Braunschweiger vehicles were the first purely electrically powered articulated battery buses in Germany to be used in regular service.
Similar to the 12-meter battery bus 1401 that was previously delivered to Braunschweig, the articulated vehicles are given a white / green sticker that differs from the red and white standard color scheme of the Verkehrs-GmbH and is intended to draw attention to the differences to the diesel vehicles.
Hamburg
At the end of 2014, Hamburger Hochbahn received two 18.75-meter-long Solaris articulated electric buses for use in the Hanseatic city . Instead of an inductive charging system, the cars were designed with a plug-in system and a fuel cell that works as a range extender . The consumption of the fuel cell of the type FCvelocity HD7 is given as around 13 kg H 2 per 100 km.
The main area of application of the two articulated wagons will initially be line 109 ( Hauptbahnhof - U Alsterdorf ), on which the elevated railway will test various innovative drive types under the same conditions. Line 109, which is designated as an innovation line for this purpose, was rededicated to Metrobus line 19 in December 2019.
In addition to the two Solaris Urbino 18.75 electric, there are also four pure fuel cell hybrid solo buses of the type Mercedes-Benz Citaro BZH , five articulated diesel hybrid buses Mercedes-Benz Citaro GDH, fifteen articulated diesel hybrid buses of the type Volvo 7900 LH Hybrid, five diesel hybrid buses Volvo 7900 Hybrid and three Volvo 7900 electric plug-in battery buses are used. In addition, the elevated railway has two double articulated buses with hybrid drives of the Hess lighTram Hybrid type , which mainly ran on the heavily frequented Metrobus line 5.
Barcelona
As part of the EU- financed ZeEUS project, two all-electric Urbino 18 articulated buses were put into service at TMB Barcelona on September 21, 2016.
The four-door articulated vehicles offer space for 110 passengers and are driven by electric motors with an output of 270 kW. The total of three batteries are designed for different charging times: During the day, during regular service on the H16 bus line (Passeig de la Zona Franca - Fòrum) , rapid charging takes place via special Endesa stations . The charging stations, which are set up in Carrer del Cisell in the area of the final stop Plaça del Nou not far from the Zona Franca and at the other end of the line in the area of the Fòrum , ensure that the charging current is transmitted by means of pantographs installed on the vehicle roof. At night in the Triangle depot , the buses are charged in a slow process. Intermediate charging during the day enables the use of smaller batteries with a capacity of 120 kWh, which are less weight.
The two Urbino 18s of TMB with the numbers 1109 and 1110 are the first exclusively battery-powered articulated buses in Spain .
