EV Telematics


Telematics connects vehicles to the cloud for real-time data, analytics, and control. It combines on-board sensors, connectivity modules, and edge compute with secure data backends to enable fleet operations, safety, compliance, and over-the-air (OTA) services across EVs and autonomous platforms.

Hardware Stack (On-Vehicle)

The hardware layer includes the telematics control unit (TCU/T-Box), connectivity modules, and sensor interfaces that collect vehicle data and transmit it securely to the cloud.

Layer Examples Primary Role
GNSS & IMU Multi-band GNSS, RTK, 9-axis IMU Position, velocity, heading, stability data
Vehicle Interfaces CAN/CAN-FD, LIN, FlexRay, Ethernet (100/1000BASE-T1) Access to BMS, powertrain, ADAS ECUs, DTCs
Connectivity 4G/5G, Wi-Fi, BLE, DSRC/C-V2X, satellite (optional) Backhaul to cloud and depot networks
Edge Compute (T-Box/DCU) Domain/Zonal controllers, secure element/TPM Local processing, buffering, encryption, OTA agent
Power & IO 12/24/48V conditioning, digital/analog IO Reliable operation across duty cycles

Software & Cloud Stack

On the backend, software and cloud services process, analyze, and distribute vehicle data, enabling fleet dashboards, predictive analytics, and integrations with enterprise systems.

Layer Functions Notes
Device OS & Agent Secure boot, PKI, FOTA/SOTA, data buffering Resilience for spotty coverage; delta updates
Ingest & Stream MQTT/HTTP, pub/sub, time-series pipelines Schema versioning; backpressure control
Storage & Models TSDB, data lake, feature store Retention tiers; PII minimization
Analytics & AI Utilization, safety scoring, energy optimization Predictive maintenance; route/charge planning
APIs & Integrations Fleet, EAM/CMMS, ERP/MRP, TMS/WMS, insurance REST/GraphQL; webhooks; secure third-party access
Dashboards & Alerts Live maps, geofences, incidents, SLA tracking Multi-tenant views; role-based access

Telematics Vendor Landscape

The vendor ecosystem spans OEM-embedded systems, aftermarket hardware, SaaS fleet platforms, and energy-focused solutions that link vehicles with charging and depot operations.

Category Examples Where They Fit
OEM Native Platforms Built-in TCU/T-Box with OEM cloud Tight BMS/ADAS integration; OTA control
Aftermarket Devices Plug-in OBD-II/J1939, hardwired CAN loggers Mixed fleets; rapid retrofit; cost-effective
Fleet Telematics SaaS Dashboards, APIs, routing, safety scoring Operations layer for dispatch and compliance
Energy/Charging Platforms Charging telemetry, depot EMS, V2G interfaces Depot/building integration; energy cost control

Market Outlook & Adoption (Ranked)

Telematics adoption is growing fastest in high-utilization fleets, with uptake shaped by operational drivers, compliance needs, and the shift to electrification.

Rank Segment Adoption Drivers Constraints
1 Last-Mile & Service Fleets High route density, uptime focus, insurance benefits Mixed vehicles, disparate OEM APIs
2 Heavy-Duty & Drayage Compliance, asset utilization, energy cost visibility Depot electrification, integration with TMS/WMS
3 Robotaxis/Autonomous Pilots Safety telemetry, OTA orchestration, incident analysis Data volumes, privacy, real-time SLAs
4 Enterprise Pools/Light Commercial Fuel/energy savings, driver safety, maintenance Change management, budget cycles
