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
System approach Electric bus operations consists of differnet parts Planning Monitoring Buses Charging stations
Stakeholder Different stakeholders with different needs • Achieving time tables and providing reliable service • Energy management Operations • Reliable and fault free buses • Charging managing Maintenance
Energy management Good day: 300 KM < unpredictable range > Bad day: 200 KM Daily fluctuating energy consumption Limited information at control center level
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?
Operations center – Ideal situation Range OK for block planning 1 more route possible Charging station defect! Linking the data necessary to get Forecasts Vehicle data essential to map Energy management
Operations: Energy management responsibility • Full coordination for all buses • Full bus schedule is taken into account • Bus driver does not have enough information (SOC only) Energy needs to be controlled from operations team, not from individual driver.
Operations: Use case data impact Vehicle data for operations team improved performance significantly 40% • Installation of ViriCiti
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
Maintenance: Battery Lifetime Battery data gives direct insights in health and remaining range of vehicle Battery only as strong as weakest module Battery degrades over time, range degrades over time! Important to monitor SOH over time! Battery module degradation example: 20% of battery cannot be used anymore! 20% Time
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
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)
Maintenance: Smart Charging Use Case 3000 • Scenario: • Without smart charging : • 60 buses • Buses charge once back in depot • Fixed charging speeds: • 75 kW • 150 kW Without smart charging 1500 0 03:00 06:00 09:00 12:00 15:00 18:00 21:00 00:00
Maintenance: Smart Charging Use Case • Scenario: • With smart charging • 60 buses • Smart charging controls charging process • Charging speed: variable 0-150 kW 3000 40% lower peak load! 1500 0 03:00 06:00 09:00 12:00 15:00 18:00 21:00 00:00 Linking of vehicle data with planning data for calculating charging power Flexible regulation of charging power, with the possibility of integrating renewable energies
What changes with the operation of electric buses? Control center Depot Recharging Recharging Range Availability Availability Vehicle data becomes necessary across all departments Recharging system necessary (“Smart Charging")
Integrated structure: maximum efficiency Smart-Charging • Exchange data between different IT systems • Combine data sources • Defined interfaces (APIs) lead to a successful split of responsibilities Monitoring CAD / AVL Yard management Planning system API API API API API = Interface
OEM independence Smart-Charging • 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) CAD / AVL Yard management Planning system A B C D
