Today electric drivetrain is in use on oceanliners, trains and trams, in the closefuture it will be adopted to commercial electric vehicles. ABB has broad rangeof components for both heavy commercial vehicle drivetrains as well as on high power charging infra.

eBus charging solutions


Opportunity charging• Charging time 15 seconds• Charging power 400 kW/ 200 kW• Energy storage grid connect 50 kW• Automated on-board pantograph• Location each 3-4 stops

Opportunity end-stop charging• Charging time 6-8 minutes• Charging power 150/300/450 kW• Demands typically CSS• Inverted pantograph at station• approaching to Street Parity• Location on each end-stop

Plug based charging AC or DC• Charging time 2-14 hours• Charging power 20-50 kW• AC on-board charge• DC off-board charging• Location depot or end-stop

4-pole; plus, minus, ground, pilot


eBus end-stop charging pantograph vs inverted


Inverted pantograph topology+ simplifies eBus –> fleet price lower+ more compact for O&M+ makes electrification of other

vehicles much easier- charging network price

On-board pantograph topology+ simplifies charging stations –>

charging ntw price lower- eBus chassis structure more rigid- positioning accuracy- more demanding for eBus O&M

Improves usage of the energy system


New CSS (Compact Secondary Substation) may be necassary if sufficient power is not available for end-stop charging


Scenario: end-stop fast charging for all vehicles



Usage of the charging network can be optimized


interoperativity with other heavy electric vehicles on slow hours such as street keeping and distribution vehicles improve usage % of the system


In the design of the charging network


there are four main points to consider.

• Existing electric network may define available installation locations

• The existing city and bus operator demands versus capacity, timing & routes

• How to achieve maximal up-time for all commercial vehicles, not just electric busses

• Whether the installation location has the adequate available space for larger vehicles

Fundamentals of electric bus charging Why eBuses are attractive application?

Routes and loads are well known - fixed - less variations Reducing emissions both – decibels and particles & smell User experience is superior – silent ride Improves usage of the energy system Reduces oil import dependence Usage of the charging network can be optimized Reduces heavy traffic on day time Puts more pressure to develop vehicles Vehicle to Grid at depot – supports energy system

Connects cityscape planning, DSO, Utilities, PTA, PTO in a new way Challenges: standardization - public purchasing



Open industry standards are key to successIndustry is working on global & EU standardization

EN/IEC 61851-23 ISO/IEC 15118 DIN70121


Summary

end-stop charging will presumably be predominat choice

inverted pantograph on automated charging stations is more cost effective than roof top pantograph on each vehicle

charging network must be open for other heavy vehicles for higher usage and TCO

Standardization of automated and plug based charging is necessary for compatibility
