External charging concepts

Cable & plug

16–80 kW charging power (limited by plug)

Conductive opportunity charging with pantograph

200–450 kW charging power

Two systems Solaris (with Eko Energetyka) Schunk Smart Charging

Inductive opportunity charging

200 kW charging power

Bombardier Primove


11/23

Range extension

Buses can be fitted with fuel cells to extend the operational range

Battery remains source of traction power

Fuel cells are used to recharge the battery

First buses for Hochbahn of Hamburg for operation on Innovation Line 109, supported by German Ministry of Transport and Digital Infrastructure

To be used in bi-articulated electric buses currently under development


12/23

Choice of length

Electric bus range covers the most common vehicle lengths

Midibus (8.9 metres, low entry)

Standard bus (12 metres, low floor)

Articulated bus (18 metres, low floor)

Extended articulated bus (18.75 metres, low floor)

Under development: Bi-articulated bus (24 metres, low floor)

Agenda

15/23

„Emil“ project: electric mobility line M19 in Braunschweig

Gefördert durch:

Inductive charging in practise

16/23

Line M19

12 km distance 1 end stop 25 stops on route 18 km/h average speed Operating freequency

every 10 minutes (working days) every 15 minutes (weekends)

More often charging operations allows to use smaller and lighter battery. Thanks to this we can keep high passenger capacity of the bus


17/23

Battery charging Inductive charging

Bombardier Primove system Dedicated pick-up coil under bus floor Dedicated inductive coil under the

surface of the street Charging station integrated with

advertising column

200 kW charging power 4 charging points/stations

with different charging times 1 at the end stop (up to 11 minutes) 2 at the bus stops (up to 30 seconds) 1 at depot (up to 15 minutes)


18/23

Vehicles

1 standard bus Inductive fast charging 60 kWh battery In service from March 2014

4 articulated buses (+ 1 option) Inductive fast charging 90 kWh battery In service from late 2014


19/23

Reliable drive and charging technology

Initial operating experience confirms reliability of electric drives and charging systems

Urbino 12 electric and Urbino 18 electric in Braunschweig in service since March and December 2014 respectively, inductively charged with Bombardier Primove

80% availability in first five months of operation of Urbino 12 electric

Energy consumption of Urbino 18 electric 1.7 kWh/km

Quiet and smooth drive characteristics

Urbino 12 electric in long-term test in Kraków, cable & plug charged

Operators (includes orders)

Tests and demonstrations (selection)

Long-term tests

Solaris is a partner in the European Union‘s ZeEUS project


Battery buses operated and tested in numerous European cities

22/23

Finding the right technologies

Market currently is in a phase of testing different concepts for electric buses

No clear indication yet which technologies will become preferred choices

Solaris supports exploration of opportunities with wide range of drive and charging technologies, adapted to individual operators‘ requirements

Open questions surrounding operational integration to be explored in practice

What will the future mix of fleets be?

Only battery buses?

Mix of battery and plug-in hybrid buses?

Mix of battery and diesel buses?

Opportunity charging or range extenders?
