A growing challenge Cities are not only the engines of future economic growth, they themselves are growing day by day. To keep up the quality of city life is a huge task and a challenge for the city s infrastructures. For public transport even on the street, electrification seems the obvious alternative to keep pace with urban growth and to care for the city environment at the same time, using fully electric or electric hybrid buses. With the right charging technology, the advantages of electrified buses can be utilized: less energy consumption in com parison to buses with combustion engines, use of renewable energy, less noise, lower particle emissions, less CO 2, lower lifecycle costs, and reliable service. Siemens is at the forefront of this tech nology to help operators find a tailored solution to their individual challenges. Why should we go all-electric? With the right charging technology, ebuses are the perfect and versatile answer to the increasing demand for sustainable transport solutions in cities Electromobility based on ebuses is locally emission free, quiet, and reliable, and can use renewable energy Using an Offboard High Power Charger means no compromise in service availability, capacity, and passenger comfort for your electric bus system 3
Siemens Offboard High Power Charger After analyzing numerous use cases of bus service operators all over the world, Siemens decided to develop a charging solution that offers substantial advantages to all parties involved in electrifying bus services. Using latest Siemens technology, the bus batteries are charged in regular intervals for three to nine minutes before returning to service. The charging duration depends on the bus in service, driving distances, potential traffic congestion, climate conditions, and the size of the batteries. The idea is to keep buses on the road in well-proven service operation all day long, instead of restricting service in terms of passenger capacity or mileage and facing other consequences as a result of overdimensioned batteries, such as increased power demand in the depot. By charging just enough for traveling all day from terminus to terminus (or to the next available charging point), the Offboard High Power Charger adds a lot of flexibility to ebus service. Since the buses occupy the charging station only for a few minutes, the Offboard High Power Charger is ideal for high-frequency operation conditions, as the charging infrastructure can be used by several buses per hour, even of different manufacturers. Why use an Offboard High Power Charger? An Offboard High Power Charger is fast, reliable, and versatile Offboard High Power Chargers can be adapted to the individual route profile and the battery size of the bus One charging terminal can be used to charge several buses successively Charging times of three to nine minutes are ideal for scheduled services Bus battery and charging equipment can be adapted to exactly fulfill the requirements of a sufficient bus service operation, making it a cost-efficient solution for the individual traffic volume. 5

Offboard High Power Charger individually designed for your city Technology is part of the city and with the advanced charging technology from Siemens, it shows. To us, the design of the charging infrastructure is more than a compulsory exercise. It is the expression of the will to emphasize the modernity and innovative strength of your city. That s why we offer not only standard off-the-shelf solutions, but also comprehensive design support to develop a design that sharpens the individual profile of your city and/or your company. The charging equipment consists of a tech nical cabinet and the actual charging pole, which is ideally installed at the termini or wherever the route allows for a few minutes stopover. The charging pole is positioned close to the curb, representing a visible expression of your traffic engineering and design innovation and as a landmark for the futuristic appeal of your city. Alternatively, the charging station can be integrated indoors in existing bus terminals or buildings. The technical equipment can be installed in existing premises or in enclosures close to the new or existing bus stations. Our experts will gladly work with you to customize proposals, so that the technical equipment can be harmoniously integrated into your traffic infrastructures and your cityscape. Choose from many options: Standardized component layout for easy adaptation Development of customized designs of charging pole and technical cabinet Internationally renowned designers Chance for high-visibility landmarks for your cityscape 7
Offboard charging If you do not have an overhead line system installed in your city (or close to the termini of your bus lines), then offboard charging is your method of choice. Offboard charging means that, all necessary equipment for charging is not installed on the bus, but stored in the technical cabinet next to the charging pole. The advantages are obvious: more space and less weight and complexity on the bus, without compromizing passenger capacity. What s more, there is no need to buy the high-power charging equipment with each vehicle, and maintenance work can concentrate on the technical cabinets. In addition, our high-power charging infrastructure is designed for a service life exceeding 20 years and offers comprehensive support for buses of different manufacturers and types right from the start and for years to come. Advantages All charging equipment except for pole and charger contacts in separate technical cabinets High-investment utilization (one charging pole can serve several vehicles, using the same equipment) More space, less complexity on the bus, and lower weight, without compromizing passenger capacity Simplified maintenance, not affecting regular service Supports ebuses of different manufacturers and types 8
Onboard charging Some operators have a well-established tram or trolleybus network in their cities. Therefore, they might want to use their existing electrical infrastructure for recharging their buses. With onboard charging, all necessary charging equipment is installed aboard the vehicle, including a pantograph for establishing the contact to the overhead line system. In this case, the charging equipment on the bus adapts to the electric parameters of the catenary system, again with obvious advantages. Charging such an ebus only requires the installation of a 2-pole catenary part. Advantages All charging equipment including the pantograph onboard the vehicle Ready to charge, wherever there is a 2-pole connection to the grid (e.g. tram catenary, trolleybus catenary) Possibly lower initial costs (depending on the availability of an overhead line close to the charging stations) 9
Hamburger Hochbahn AG, Innovation Line 109 The Innovation Line 109 in Hamburg features among other systems two diesel-electric hybrid buses from Volvo, and charging stations electrically equipped by Siemens. The offboard opportunity charging system consists of charging poles at the termini and a fully automated six-to-eight-minute charging process, once the bus is positioned under the charging pole and the handbrake is activated. With Innovation Line 109, an innercity line extending approximately 10 km, we are showing what we can and want to achieve with innovative drives thanks to suitable charging technology an attractive public transportation system for a higher quality of life in the city. This technology is an important step toward achieving our strategic goal of purchasing exclusively zero-emissions buses starting from the year 2020. Ulrike Riedel, Human Resources & COO, Hamburger Hochbahn AG 10
Wiener Linien GmbH & Co KG, electric bus lines 2A/3A With 2A and 3A, its two inner-city bus lines, Wiener Linien is rigorously pursuing its course toward clean, quiet traffic in the downtown area. Thanks to intelligent opportunity charging technology, Wiener Linien can increase performance and ensure a long service life for vehicle batteries. In Vienna, 12 buses electrically equipped by Siemens were commissioned by Wiener Linien for scheduled service in 2012. The buses feature an onboard opportunity charging system and recharge for 10 minutes at every terminus by connecting to the overhead lines of the Wiener Linien tram lines. 11
