Overview
Our client, a leader in the electric vehicle (EV) industry, sought a telematic dashboard to provide real-time data insights into vehicle performance and status. The goal was to enhance operational decision-making for the company and deliver valuable data to its customers. Leveraging a robust tech stack—including Azure IoT Hub, NextJS, Python, Azure Functions, Postgres, and Highcharts—Tetraimpacts delivered a comprehensive solution tailored to the dynamic needs of the EV market.
Challenges
Before implementing the telematic dashboard, the client faced several challenges, including:
Limited Real-Time Data: Delayed access to vehicle performance metrics hindered proactive maintenance and optimization.
Scalability Issues: Existing systems struggled to handle growing volumes of data as the fleet expanded.
Data Security Risks: Ensuring secure data transmission and storage was critical for protecting sensitive vehicle information.
Visualization Limitations: A lack of interactive tools made it difficult for users to explore and understand the data.
Solution
Tetraimpacts designed a scalable and secure telematic dashboard that centralized data collection, processing, and visualization. Key features included:
Real-Time Data Collection: IoT devices installed in each vehicle transmitted telemetry data to Azure IoT Hub, enabling instant access to critical metrics such as battery health, charging status, and location.
Automated Data Processing: Python scripts running on Azure Functions cleaned, analyzed, and aggregated incoming data streams, ensuring accuracy and relevance.
Interactive Data Visualization: A user-friendly dashboard developed with NextJS and Highcharts allowed users to explore vehicle data through responsive and interactive charts.
Secure Data Management: Processed data was stored in a Postgres database with encryption in transit and at rest, ensuring both performance and security.
Technology Stack
Azure IoT Hub: Centralized platform for secure data collection and device management.
NextJS: Frontend framework for building the dashboard interface.
Python: Backend data processing and analytics.
