1. THE POWER OF DATA & VALUE OF SMART CHARGING

2. About us
Focus on the leading monitoring solution for the electric buses
Founded in 2012
Amsterdam, Netherlands (HQ)
USA California & South Carolina
Market leader in Europe and North America
About 1200 electric buses connected
Worldclass customers

3. System approach Electric bus operations consists of differnet parts
Planning
Buses
Charging stations
Monitoring

4. Stakeholder Different stakeholders with different needs
Operations
Achieving time tables and providing reliable service
Energy management
Maintenance
Reliable and fault free buses
Charging managing

5. Implications for the operations team

6. < unpredictable range >
Energy management
Good day: 300 KM
Bad day: 200 KM
< unpredictable range >
Daily fluctuating
energy consumption
Limited information at control center level

7. Operations center – Current situation? ? ?
Remaining range
Can the bus finish the block schedule?
Schedule delay
Can the bus continue without recharging?
SOC
Is the charging station available?

8. Operations center – Ideal situation
Range OK for block planning
1 more route possible
Charging station defect!
Vehicle data essential to map Energy management
Linking the data necessary to get Forecasts

9. Operations: Energy management responsibility
Energy needs to be controlled from operations team, not from individual driver.
Full coordination for all buses
Full bus schedule is taken into account
Bus driver does not have enough information (SOC only)

10. Operations: Use case data impact
Vehicle data for operations team improved performance significantly
40%
Installation of ViriCiti

11. Impact on Maintenance

12. Maintenance responsibilities
Maintenance needs to take care of new responsibilities
Vehicle management:
Battery lifetime
Faults & issues
Charge management:
Charge station overview
Smart charging
Battery health
Charging stations
Peak loads

13. Maintenance: Battery Lifetime
Battery data gives direct insights in health and remaining range of vehicle
Battery module degradation example:
Battery only as strong as weakest module
Battery degrades over time, range degrades over time!
Important to monitor SOH over time!
20% of battery cannot be used anymore!
20%
Let’s take the example of a broken battery here.
My bus is fully charged
While driving the battery is being used up to the moment where one pack reaches the lowest state of charge, and therefore the battery shuts down.
Time

14. Maintenance: Charge Station Status
Monitoring of charging stations is key to ensure a high reliability of bus operations
Buses need to charge when connected
Detect problem in real-time
80% of issues solved remotely
Best practice: Charge stations should be able to communicate with back-offices via OCPP (1.6 or 2.0 preferred)
OCPP

15. Maintenance: Smart Charging
Making sure large bus fleets are charged on time, with the minimal costs and grid constraints
What does smart charging do?
Controls bus charging processes
Load balance between chargers and maximum available grid capacity
Why smart charging?
Enables charging flexibility and efficiency
Reduces utility costs (energy / peak load costs)

19. Integrated structure: maximum efficiency
Planning system
Exchange data between different IT systems
Combine data sources
Defined interfaces (APIs) lead to a successful split of responsibilities

API = Interface

20. OEM independence One responsible party to manage interfaces (APIs)
Planning system
One responsible party to manage interfaces (APIs)
One system for all vehicle and charging station types
Same data requirements and calculations for different vehicle types (aligned datasets)
