Electric and emission-free urban buses are being introduced worldwide. According to Germany’s public transport association VDV, there are around 400 electric buses in operation in Germany and another 750 on order. In order to discuss the progress, challenges and future development of the sector, the German public transport association VDV organized the Electric Bus conference in Berlin for the 11th time from 4 until 5 February 2020. Around 70 national and international manufacturers and suppliers presented the latest developments in terms of emission-free buses, technologies and technical solutions. During the two-day event, around 700 visitors came to the conference and e-bus exhibition. The VDV Electric Bus conference has been organized by the VDV, together with the Forum for Transport and Logistics, DEVK Insurance and the National Organization for Hydrogen and Fuel Cell Technology (NOW). The latter is the coordinating partner of the German Ministry of Transport for Fuel Cell and Electric Mobility funding projects.
Let’s have a look at the 16 electric and emission-free buses on display.
Alstom showed its Aptis electric bus. After extensive testing in many French and European cities for the past two years, the serial design of Alstom’s 100% electric mobility solution incorporates feedback from passengers and transport operators. The start of operation of the first serial Aptis will start on 24 February 2020 in Strasbourg on a Bus Rapid Transit (BHNS, Bus à Haut Niveau de Service). The 3.2 km line H links the central station with the European parliament. In comparison to the protoypes, the weight has been further reduced by 15%. In combination with the use of new, more efficient and state of the art batteries, the range has been increased. A new air-conditioning system that (fully electrical heat-pump) maximises thermal comfort and the panoramic rear lounge has been enhanced to give a feeling of increased space. The new hydraulic suspension allows superior comfort and sound insulation.
Aptis is particularly popular in France, where it is also built. It has already been chosen by Paris in the context of Europe’s largest call for tender for electric buses, as well as by the cities of Strasbourg, Grenoble, La Rochelle and Toulon.
BYD is the world’s biggest manufacturer of electric buses. Since 2010, the company has produced over 50,0000 electric buses with iron phosphate Li-Ion batteries (LiFePo). A large portion of the buses is running in Chinese cities, but the company also delivered electric buses to London, Landskrona in Sweden, France, the Netherlands, Spain and Houston, USA. The first electric BYD buses in Germany will start operating in Bochum from summer 2020 on and run on route 354 in Bochum, route 380 in Gelsenkirchen, and in Herne. The 12 meter e-buses can carry up to 80 passengers and have a single charge range of more than 200 kilometers with air conditioning.
Ebusco exhibited two e-bus models. The Ebusco 2.2 12-meter city bus which has a range of up to 350 km. With the optional >400 kWh battery pack, the Ebusco 2.2 (12 meters) can even operate a range of up to 450 km. With this, practically all city and regional transport can run on 1 battery in a day.
Ebusco also presented the Ebusco 3.0 which even has range of 500 km thanks to light weight design by using composite materials. The first series vehicles will go into production in Deurne, Netherlands in mid 2020. As one of the first operators in Germany, Munich is already operating 6 Ebusco e-buses on line 100 with a further 2 + 16 e-buses on order.
Daimler/ Evobus GmbH
Daimler presented its 12 meter eCitaro electric bus which has entered in operation in numerous cities in Germany and other countries during the past 12 months. The 18 meter version will be presented later this year. As the only electric bus to date, the eCitaro will even bear the coveted “Blue Angel” eco badge. This is to certify the eco-friendliness of the eCitaro and the sustainable way towards locally emission-free public transport. The Blue Angel is an environmental label awarded in Germany since 1978 for particularly environmentally friendly products and services.
e-troFit is a subsidiary of the Garching-based development company in-tech. For many years, in-tech has been doing development activities for leading automobile manufacturers. Since 2016, an in-tech innovation team has been working e-mobility. In order to launch these activities, in-tech founded its subsidiary company e-troFit GmbH in 2019. The Ingolstadt-based company is now responsible for the development, series production and distribution of the e-troFit solution.
e-troFit presented its converted Citaro electric bus which used to be a diesel bus. According to the manufacturer, the conversion is much cheaper than the procurement of new vehicles. Depending on the condition of the vehicle and the extent of the work, the conversion can cost between 300,000 and 350,000 Euro per bus. This is about half the price of new electric buses.
Hess did not presented any bus, but showcased its latest e-bus products. One of the latest e-bus projects is the bi-articulated LighTram bi-articulated e-buses in Nantes, France, which are recharged via ABB charging stations.
Iveco zeigte den in Frankreich entwickelten und gefertigten Heuliez GX 337 E, der insbesondre durch sein eleganten Innen- und Außendesign besticht. Zwar lassen Aufträge aus Deutschland noch auf sich warten, aber dafür konnte die Iveco-Tochter Heuliez bereits vier Elektrobus an die ÖBB Postbus nach Vorarlberg liefern. Paris’ public transport operator ordered 50 Heuliez GX 337 E.
Step by step, Irizar is conquering the European e-bus market. The Spain-based manufacturer is already present in various countries. In Berlin, Irizar showed one of 14 x 18 m ie bus of the operator Voyages Emilie Weber. The buses have been delivered in 2019 and joined the seven 12 m Irizar ie bus units that were already in service in Luxembourg. The 18 m articulated buses have a capacity of 525 kWh and are re-charge over-night in the depot. Later this year, Irizar will also deliver 10 e-buses to Rheinbahn, Düsseldorf.
