The Challenge

An Indian EV fleet operator managing 500+ electric delivery vehicles needed real-time battery health monitoring, intelligent route planning that accounts for charging station availability and battery range, and predictive maintenance alerts — challenges unique to EV fleets that traditional fleet software cannot handle.

The Solution

Ubikon built a Go backend for high-throughput IoT data ingestion (10K+ events/second) from vehicle telematics devices, a Flutter driver app with turn-by-turn navigation optimised for EV range, TimescaleDB for time-series battery analytics, MQTT for real-time telemetry, and an admin dashboard with fleet health overview and charging station management.

How We Built It

IoT Architecture

MQTT broker setup, vehicle telematics protocol design, AWS IoT Core for device management.

Data Pipeline

Go microservices ingesting 10K events/sec, TimescaleDB for battery telemetry, real-time anomaly detection.

Route Optimizer

Google Maps integration with EV-specific constraints: battery state, charger locations, elevation, payload weight.

Driver App

Flutter app with live battery gauge, nearest charger finder, delivery management, breakdown SOS button.

Admin Dashboard

Fleet health overview, predictive maintenance alerts, charging cost analytics, driver performance scoring.

"GreenFleet solved the biggest pain point of running an EV fleet — range anxiety. The route optimizer considers real-time battery state, traffic, and charging station availability. We prevented 340 roadside breakdowns in the first year. Ubikon built the system the EV industry desperately needed."
