bit.ly/TOMP-WG
• Research into MaaS
architectures, including
e-mobility & charging
• Standardization of
communication
• Research on EV Uptake
• Transnational Survey on
EV Knowledge
e.g. 21% in NL agreed that
charging on the go is still to
difficult, 26% disagreed, 28%
doesn’t know
• Simulation Model of EV
Uptake – ADAM & EV

10-03-2020 – Future Of Charging Symposium3. Model Outcomes
Many more scenarios can be (and were) explored
• 5 predefined charging strategies
• 5 predefined connection management strategies
• # of chargers
• # of employees & average travel
• Grid Connection Capacity
• Installed PV Capacity
• Building Energy Requirements
• Energy Cost
• EV Type (range & efficiency)
Lessons Learned (1)
Main Learnings
Switch to EV fleet
55% to 65% reduction for energy bill & CO2 emitted
Smart Charging in addition
can establish a further 10% reduction
Most important development
A Charging Speed Algorithm taking into account all parked EVs:
Current SoC level | Next departure time | Next trip distance or energy need
Less influential
Solar Forecast (depends on amount of PV capacity) & Parking History Data

Lessons Learned (2)
Other considerations
Smart charging can remove the need for electrical infrastructure expansion
Traditional
1 connection per 2 employees
Smart
1 connection per 8 employees
Depends on scenario and travelling behaviour
Support employees with home EVSEs – can help to reduce load at company
locations
