Fleet telematics is the use of connected vehicle hardware and software to collect, transmit, and analyze operational data from fleet vehicles—such as location, mileage, energy/fuel use, driver behavior, and vehicle health—to improve efficiency, safety, compliance, and cost control. In EV fleets, telematics is also a key input for charging planning, readiness, and CO₂ reporting.
What is fleet telematics?
A telematics system typically includes:
– An onboard device (OEM embedded modem, OBD device, or CAN-bus integration)
– GPS + cellular connectivity to transmit data
– A cloud platform for dashboards, alerts, and reporting
– APIs/integrations into fleet management, maintenance, payroll, and charging systems
What telematics data fleets track
Vehicle usage and operations
– Mileage (km), trip history, routes, dwell times
– Vehicle utilization: time driving vs parked
– Vehicle location and geofencing (depot entry/exit)
Energy and efficiency (EV + ICE)
– Fuel consumption (L/100 km) or energy consumption (kWh/100 km)
– Idling time (ICE) and inefficient driving patterns
– Regenerative braking and efficiency by route/driver (EV)
Driver behavior and safety
– Harsh braking/acceleration, speeding events
– Seatbelt compliance (where available)
– Fatigue indicators and hours compliance (market-dependent)
Vehicle health and maintenance
– Fault codes, battery health indicators, service intervals
– Tire pressure (if supported), temperature impacts
– EV-specific: SoC, battery temperature, charging events (sometimes)
Why fleet telematics matters for EV charging
– Improves charging demand forecasting (who needs how much kWh)
– Enables departure-based scheduling (arrival/departure + energy need prediction)
– Helps reduce public charging reliance by predicting exceptions early
– Improves cost allocation and billing reconciliation (vehicle-session matching)
– Strengthens CO₂ reporting with accurate distance and energy intensity data
Telematics vs charging data (how they complement each other)
Charging systems (CPMS) provide:
– kWh delivered per session, charger/site ID, time stamps, user credentials
Telematics provides:
– vehicle km, route patterns, dwell windows, energy consumption rate, SoC trends
Together they enable:
– Readiness KPIs (vehicle charged enough for route)
– Accurate €/km and emissions intensity calculations
– Better infrastructure sizing and utilization planning
Common integrations for EV fleets
– CPMS/EMS ↔ telematics (vehicle energy need + departure deadlines)
– Telematics ↔ maintenance system (predictive servicing, fault workflows)
– Telematics ↔ payroll/HR (driver scoring, compliance workflows where lawful)
– Telematics ↔ ERP/finance (cost centers, billing allocation)
– Telematics ↔ CO₂ reporting tools (Scope 1/2 metrics, intensity reporting)
Key requirements to specify
– Data fields: vehicle ID, time stamps, mileage, SoC (if needed), consumption, location
– Update frequency (real-time vs periodic) and acceptable latency
– API access, export formats, retention, and audit rights
– Privacy and role-based access control for driver-identifiable data
– Data quality rules: handling missing GPS, odometer drift, and vehicle reassignment
Common mistakes
– Not standardizing vehicle IDs across systems → broken matching and reporting
– Over-collecting personal data without governance → privacy risk
– Relying on GPS-only without odometer/energy data for cost and CO₂ reporting
– No process for vehicle reassignment between depots → forecasting errors
– Treating dashboards as enough—without APIs, automation and reporting scale poorly
