Overview

The Electric Vehicle Data Recorder is a custom-developed system designed to log real-time performance metrics of electric vehicles (EVs) during actual operating conditions. Built using an Arduino Mega, SD card shield, and real-time clock (RTC), the system captures and stores voltage and current data from critical EV components—battery, supercapacitor, and motor. This data logging capability aids engineers in evaluating system behaviour, enhancing performance, and supporting the advancement of next-generation EV technologies

Key Features

  • Multi-Channel Monitoring: Utilizes six analog-to-digital channels—three for voltage and three for current—for full system coverage.
  • Real-Time Data Logging: Data is recorded with time stamps on an SD card for offline analysis.
  • Precise Measurements: Voltage is scaled via potential dividers and sensors; current is detected through Hall Effect-based non-contact sensors.
  • Arduino-Based System: Uses Arduino Mega with 10-bit ADC, offering 1,024 levels of analog signal resolution.
  • Modular and Expandable: Compatible with additional sensors or modules for future upgrades.
  • Continuous Monitoring: Ensures ongoing tracking of key performance metrics under dynamic driving conditions.
  • Compact and Portable: Designed for in-vehicle deployment without disrupting existing systems.

Potential Applications

  • EV Prototype Testing: Enables developers to capture real-world performance metrics during trials.
  • Battery and Powertrain Analysis: Supports detailed evaluation of battery discharge, motor load, and power flow efficiency.
  • Research and Development: Ideal for academic and industrial R&D in electric mobility.
  • Predictive Maintenance: Long-term data collection can inform maintenance scheduling and fault detection.
  • Performance Optimization: Assists in fine-tuning control algorithms and energy management systems.
