Why This Matters
Why scheduled servicing fails on electric fleets
Internal combustion vehicles wear out in ways a workshop can see and a calendar can predict. Brake pads thin, oil ages, belts fray. Electric vehicles do not follow that pattern. They degrade electrochemically inside the battery pack, and the first visible symptom is often a stranded vehicle on a route.
Across Indian fleets, the dominant failure mode is usually not a dramatic one. It is gradual capacity loss, silent cell imbalance, and thermal stress that builds in sustained heat above 40°C and under repeated high state-of-charge cycling. A fleet that follows an OEM service schedule and nothing else has no live view into that failure curve until the vehicle drops out of service or the warranty window is already closing.
Predictive maintenance closes that gap. It moves the decision out of the breakdown moment and into a planned service window, where parts, technicians, and vehicle swaps can be lined up before revenue is lost.
Cell imbalance is invisible to drivers.
Thermal stress accumulates silently in Indian heat.
A single bad cell can derate the entire pack.
What Navionyx Delivers
What Navionyx predictive maintenance delivers
This is a vehicle-health operating layer for fleet teams, OEM warranty teams, and financiers who need to act before breakdowns turn into cost and downtime.
Battery degradation trend alerts
Track State of Health and capacity fade over time, then flag packs when decline accelerates beyond the expected curve for that duty cycle.
Cell temperature anomaly detection
Read live cell level temperature data where the BMS supports it and catch outlier deltas before thermal issues become field failures.
Usage based maintenance reminders
Move away from fixed service intervals with reminders based on distance, charging cycles, fast charge frequency, load, and route severity.
Breakdown risk indicators
Score battery, motor controller, and thermal-system risk per vehicle so dispatchers can route around high-risk assets before breakdowns happen.
Full maintenance history
Store every alert, inspection, part replacement, and SoH reading against the vehicle lifecycle for service, resale, and battery passport workflows.
Warranty support data
Export structured fault-window evidence including cell voltages, temperatures, charging logs, and fault codes for OEM warranty claims.
Cell anomaly detected
Outlier temperature and voltage deviation identify the cluster that needs inspection before it derates the full pack.
Degradation trendline
Trend-based alerts matter more than one-off readings when you need a 60 to 90 day planning window.
Usage-based service clock
Fast charging frequency, route severity, and duty cycle all feed the next maintenance recommendation.
Fleet Workflow
How it works across your fleet
From field hardware to a same-day maintenance call, the platform is designed to turn raw EV telemetry into operational decisions.
01
Connect
Install the Navionyx VLTD or telematics gateway and read from the BMS, motor controller, and charging port over CAN, OBD, or supported OEM protocols.
02
Stream
Transmit cell voltages, pack temperatures, charging events, motor telemetry, and trip data to the Navionyx cloud in real time.
03
Score
Compute SoH, capacity fade slope, cell deviation, thermal exposure, and usage intensity into a live maintenance risk score.
04
Act
Push alerts to dashboards, the Navionyx EV app, WhatsApp, and email with clear actions like inspect, recall to depot, or do not dispatch.
Driver App Visibility
Driver side visibility through the Navionyx EV app
A predictive maintenance system that only speaks to the operations centre still leaves the driver guessing. Navionyx pushes the same intelligence to the EV driver app so the person behind the wheel sees what the platform sees.
Drivers receive alerts for battery health changes, irregular charging sessions, cell temperature warnings, and upcoming usage-based service due dates. Each alert is written in plain language with a clear next step, which helps teams close the gap between fault detection, fleet awareness, and driver behaviour.
This same visibility becomes the foundation for the Navionyx battery-health record that follows the asset through first deployment, warranty review, second life, and resale.
Best Fit
Who this is built for
Fleet operators
Best for last mile delivery, FMCG, intracity goods, and shared mobility fleets where uptime targets are above 95% and route windows are tight.
EV OEMs
Get live field visibility on pack performance, faster warranty closure, and cleaner operating data for the next product generation.
State transport undertakings
Protect schedule reliability for public routes where a single battery-related stoppage becomes a visible service failure.
Last mile delivery and NBFCs
Monitor SoH per asset, defer pack replacement, and price lease-end residual value on verifiable battery-health data instead of assumptions.

Platform Connection
How this connects to the rest of the Navionyx platform
Predictive maintenance does not sit alone. It draws on the same telematics layer that powers EV charging analytics, the same alerting engine that supports our AI dashcam safety workflows, and the same lifecycle data foundation used in the Navionyx EV Battery Health Certificate.
That same history becomes valuable again at vehicle exit, where our EV resale value intelligence solution turns battery-health evidence into pricing confidence for remarketing, dealer resale, and residual-value review.
If you operate a mixed EV and ICE fleet, the same dashboard can layer fuel monitoring and driver safety on top of EV health so one operations team can run the entire fleet without switching tools. If you are an OEM or enterprise partner, the same data can be exposed through our partner-facing APIs for warranty and service workflows.

FAQ
Frequently asked questions
It is a maintenance approach that uses live data from the vehicle, including battery, motor, thermal system, and charging signals, to predict failures before they happen instead of relying on fixed service intervals.
The onboard BMS protects the pack in real time, but Navionyx sits above it. We retain history, compare each vehicle to its own baseline and the rest of the fleet, and model degradation trends over time. The BMS reacts. Predictive maintenance forecasts.
We support vehicles that expose telematics over AIS 140, CAN, OBD, or a documented OEM protocol. That covers most Indian electric three-wheelers, cargo LCVs, and electric buses used commercially today.
A typical pilot covering 25 to 100 vehicles can be live in two to four weeks, including hardware fitment, BMS integration where required, and dashboard configuration.
We generate a structured warranty pack containing pre-fault telematics, cell voltages and temperatures across the failure window, charging history, fault codes, and the relevant SoH trendline.
Yes. Navionyx is AIS 140 certified and DPIIT recognised, with deployments incubated through SINE IIT Bombay. Platform access is role-based for fleets, OEMs, and authorised stakeholders.
