Charging time for different vehicle sizes and velocities
Standing charging: idle time due to opportunity / flash charging
Velocity of Bus 12m standard bus 18m articulated bus 24m double artic bus
15 km/h 3,4 min 5,6% 5,6 min 9,4% 7,9 min 13%
20 km/h 4,5 min 7,5% 7,5 min 12,5% 10,5 min 17,5%
30 km/h 6,8 min 11,2% 11,2min 18,7% 15,8 min 26,5%
Assumed charging power: 400 kW
Energy consumptions: 12m: 1,5 kWh/km; 18m: 2,5 kWh/km; 24m: 3,5 kWh/km
Higher velocity
Longer vehicle
more energy consumption per hour
longer charging time / idle time
higher costs due to x% additional buses (& driver?)
Opportunity/Flash charging is mainly suitable for:
Low average velocity lines
Short vehicles
For 1 hour driving idle time of standing bus

TCO 18m diesel bus
Bus driver:
> 50%
Energy:
> 20%
Vehicle: < 15%
Costs pro km for 18 m diesel
bus
Bus driver is the cost driver

In Motion Charging (IMC)
- During operation time
- With powerful* air cooled power supply
- 50% of the energy** (for 50% wireless)
- During passengers transportation
Transferring electrical energy
Concept of e-bus charging: Standing vs In Motion Charging
Standing charging
- During limited time slots
- With limited power
- 100% of the energy (traction, heating, etc)
- No service during charging
* In Motion Charging possible with up to 525 kW continuous
** The rest goes straight to the motor – bypassing the battery
btw: Energy transfer from copper wire via coal to vehicle
is used also for trams, locomotives up to high speed trains copper wire
coal
IMC is the most powerful charging concept for battery buses bottleneck gets resolved

When batteries get better …
What will actually change?
If the battery : - Price will be reduced by 20% TCO will be reduced slightly.
- Energy density will increase by 15% Three passengers more *
- Power density will increase by 15% see energy density
** if more energy gets installed for increasing the range longer charging time
* 1500kg Battery , thus 225kg less weight
The charging challenge remains!
… or gets worse**

Modern e-bus propulsion systems
Why the wires?
Reliable e-bus concept with very high availability Low vehicle reserve needed
Highest energy efficiency & through sustainable overhead wires and less batteries
“Unlimited” energy available “just in time”
convenient for heating & air conditioning, infotainment
High passenger capacity of 24 meter possible (with few personnel)
Fast with powerful characteristics
Range of Zero Emission operation is “unlimited” (also in very cold or hot weather conditions)
IMC battery charging is easy on battery and therefore on battery live time
Universal interface for battery charging (not tying up to an unique provider with monopole)
Bus driver doesn’t have to wait for battery recharging (TCO)
Low peak power requirement for substations
Most economical zero emission bus operation for medium to high transportation capacity
Allows big fleets of electrical buses
