2013: 16 chargers at 250A 2018: 100 chargers at 400A Smart charging saved ~€250.000

• n infrastructural costs

Smart charging is active ~10%

• f the time, resulting in a 90%

higher charge rate for an EV

Use case

Head office of the largest Dutch grid operator

Learnings

• 1. Data is crucial and not

always available

• 2. Some cars do not respond

to smart charging signals Smart charging can be a challenge

• 4. Possible network failure

requires fallback scenario’s

• 3. Some cars

are on timers

• 5. Data costs can ruin

your business case

• 6. Limited bandwidth

with 2G

Learnings

GreenFlux Smart Charging 34

Electric Nation project

Learnings - 1

Demand management is technically feasible, and acceptable to the majority of participants

GreenFlux Smart Charging 35

Electric Nation project

GreenFlux Smart Charging 36

Electric Nation project

Learnings - 2

Data from smart chargers can provide a strong data source for building an evidence base for future developments Data shows there is a lot of flexibility in EV charging

GreenFlux Smart Charging 37

Electric Nation project

Learnings - 3

Informing and empowering EV- drivers is crucial in smart charging It needs to be easy

GreenFlux Smart Charging 38

• Finding chargers
• Smart charging
• Roaming and Paying

The best apps never leave the pocket

GreenFlux Smart Charging 39

Electric Nation project

Learnings - 4

Trial data shows that Time of Use incentives appear to be highly effective at moving demand away from the evening peak. The right incentive is crucial though

Start of charging time – Dynamic Tariffs

This is great for the grid, For the energy supplier: not so much

What we now offer

GreenFlux Smart Charging 44

Electric Nation project

Learnings - 5

Waiting 15 minutes for a recalculation can be annoying

GreenFlux Smart Charging 45

Switching to event-based algorithms

GreenFlux Smart Charging 46

Switching to event-based algorithms

Our developers call this “smart charging art”

GreenFlux Smart Charging 47

Switching to event-based algorithms

Responding directly to events:

• Start of charge session
• Stop of charge session
• EV nearly full
• EV full
• High priority request from driver
• High priority request from charger
• DC charger starting a session
• Sudden change in available capacity
• New setpoint from energy supplier
• New setpoint from TSO
• …
