Battery Management System Testing Framework

Battery packs are used extensively in power plants, automotive, Electric vehicles, aircrafts etc. Battery management systems are used to manage these rechargeable cells or battery packs and include monitoring battery state, calculating secondary data, reporting that data, controlling its environment, authenticating and balancing it. It is vital to test the Protection features and reliability of BMS to prevent the batteries from overcharging, blast and short circuit.

eInfochips Battery Management System Framework utilizes Hardware-in-Loop system to verify, validate, and test BMS functionality

The framework can be used to test applications as well as connected products.  The framework generates a feature file for each test case added in test management, executes it using developed keywords and then uploads all test results into a test management tool using the framework libraries.

Key Features

  • Hardware-in-the-Loop test of Battery Management System controllers and hardware components
  • Real-time battery simulation in Simulink/Simscape
  • Simulate battery voltage, capacity, and SOC parameters
  • Experience with real-time target machines (i.e., Speedgoat) and fault insertion units
  • Emulate fault scenarios for battery cell/pack and test different fault and protection features (i.e., Over temperature, Overcharge or Over discharge)
  • Useful for BMS algorithm development and large-scale automated testing

Functionality Covered

  • Overcharge Protection
  • Over discharge Protection
  • Over current Protection
  • Short Circuit Protection
  • Over temperature Protection
  • Under Temperature Protection
  • Balancing Cells
  • SOC Estimation (state of charge)
  • SOH Estimation (state of health)


  • The BMS HIL Test System is the ideal platform to use when developing and testing a battery management system and a wide range of battery-sensitive electronics providing exhaustive test coverage from functional and reliability standpoint
  • eInfochips HIL test system also provides a safe and efficient method of simulating a high voltage battery
  • It is capable to implement irregular and dangerous physical battery conditions. Our system improves the quality of testing with repeatable stimulus
  • Enables testing of different types of battery pack with different type of battery chemistry
  • One of the main benefits is reducing testing cycle duration and cost as we are not using physical batteries
  • Also, the framework enables reducing the development process significantly through executing of known test scenarios
