Electric vehicles now account for over 20% of new commercial van registrations in the UK and growing proportions across Western Europe. Fleet managers who built their telematics systems around combustion vehicles — fuel consumption, engine hours, DTC codes — are discovering that EV fleets require a fundamentally different data model. State of charge is not fuel level. Charging events are not refuelling stops. Range is not constant. Energy cost is not pence-per-litre. GoAndTrack's BYOD architecture connects to EV-compatible OBD-II trackers and CAN-bus enabled EV data sources to deliver the intelligence that manages this new operational reality.
What Changes When You Electrify a Fleet
Combustion Fleet: What You Tracked
- Fuel level (relatively stable between fills)
- Fuel consumption (litres/100km, predictable by vehicle)
- Engine oil, coolant temperature
- Service intervals by mileage or time
- DTC fault codes (mechanical focus)
- Driver behaviour (harsh braking, acceleration)
- Fixed refuelling locations (any fuel station)
EV Fleet: What You Need to Track
- State of charge (constantly changing, weather-dependent)
- Energy consumption (kWh/km, highly variable by load and conditions)
- Battery health (degradation over cycles)
- Charging events (location, duration, speed, cost)
- Real-time range prediction (not nameplate range)
- Regenerative braking efficiency per driver
- Charging infrastructure availability and compatibility
The most operationally critical difference is range predictability. A combustion van with 25% fuel has approximately the same effective range regardless of ambient temperature, load, or driver behaviour — perhaps ±15%. The same van electrified at 25% state of charge might have 40 miles of range in summer or 22 miles in a cold January morning with heating running and a full load. The operational consequence: dispatch decisions that were straightforward with combustion vehicles require real-time data with EVs.
State of Charge Monitoring: The Core EV Fleet KPI
State of charge (SoC) is the EV equivalent of fuel level — with two important differences: it changes more dynamically than fuel level (regenerative braking adds charge during a journey; cold temperatures reduce apparent SoC) and it has operational significance at both extremes. Running to 0% strands a vehicle. Regularly charging to 100% degrades battery health. The optimal operational band for most EV fleet batteries is 20–80% SoC.

Tracking Devices Compatible with EV OBD-II
Teltonika FMB920 / FMC130 (EV OBD-II Compatible)
Teltonika's OBD-II trackers access EV-specific CAN bus PIDs on compatible vehicles — including Ford E-Transit, Volkswagen e-Crafter, Renault Master E-Tech, and Vauxhall Vivaro-e. State of charge, estimated range, charging status, and energy consumption per trip are all accessible via OBD-II on these models. Not all EV makes expose all PIDs — verify specific vehicle model compatibility before fleet-wide deployment.
Queclink GV600 / AT4 (EV OBD Variant)
Queclink's OBD variants access EV CAN bus data on supported models. Strong APAC market presence makes this relevant for EV fleet operations in Asian markets where different EV manufacturers dominate (BYD, NIO, Zeekr). GoAndTrack connects via native Queclink protocol and normalises EV-specific telemetry alongside GPS position data.
Vehicle API Direct Integration (Expanding)
An increasing number of EV manufacturers provide fleet API access to vehicle data — Ford Fleet Management API, Volkswagen Fleet Connect, and similar. For operations standardised on a single EV manufacturer, direct API integration provides richer data than OBD-II (including cabin pre-conditioning commands and charge scheduling). GoAndTrack's BYOD architecture supports API-based EV data alongside OBD-II GPS trackers in a unified fleet view.
AI Queries That Transform EV Fleet Operations
Charging Event Management
Charging events are operationally significant in a way that combustion refuelling isn't — they take longer (even rapid DC charging takes 20–45 minutes for a meaningful charge), they happen at specific infrastructure locations with availability constraints, and they have cost implications that vary by charger type, network, and time of day.
GoAndTrack detects charging events from OBD-II data (charging status flag, SoC increase while stationary) and logs: start time and location, SoC at start and end of charge, energy added (kWh), duration, and estimated cost (based on configured charger rate by location type). This creates an auditable energy cost record per vehicle, per driver, and per route — replacing the spreadsheet-based expense reconciliation that most EV fleet managers currently run manually.

Key Takeaways
- EV fleet management requires a fundamentally different data model than combustion tracking: state of charge, real-time range prediction, charging event monitoring, and energy cost tracking replace fuel level, DTC codes, and litres-per-kilometre
- Range prediction for EV fleets cannot use nameplate figures — weather-adjusted, load-adjusted range estimates from live SoC and route data change operational dispatch decisions materially, especially in winter
- Teltonika and Queclink OBD-II trackers access EV-specific CAN bus PIDs on compatible vehicles (Ford E-Transit, Renault Master E-Tech, Vauxhall Vivaro-e, Volkswagen e-Crafter) — providing GoAndTrack with live SoC, charging status, and energy consumption data
- Charging event management — start/end SoC, duration, energy added, cost — creates an auditable energy cost record per vehicle and driver, replacing manual expense reconciliation
- GoAndTrack handles mixed EV + combustion fleets in one unified dashboard — the transition period where both vehicle types coexist is a first-class supported configuration, not an edge case
