Hybrid Energy Lab – System

A Fuel Cell – Battery Hybrid System that enables users to understand & research individual components and system behavior under various hybrid set-ups. Designed as a lab to support engineering courses focussed on the application of fuel cells, battery technology, hybrid systems, energy management and energy storage. Critical to today’s engineering students is a deep understanding of the application of electrical chemical energy conversion & storage. Especially as it relates to fast growing markets of stationary, portable and mobile hybrid power systems.

Ideal for Courses Focused On

  • Battery Technology (Modeling)
  • Battery Systems & Control
  • Applied Fuel Cell Technology
  • Battery- Fuel Cell Hybrids
  • Electrochemical Energy Storage & Conversion
  • Renewable Energy Storage
  • Electrical & Hybrid Vehicles (HEV/FCEV)
  • Backup Power Systems
  • Micro-Grids & Smart Grids

Key Features

The system provides an experimental platform for advanced training to applied research:

  • Fuel Cell – Battery Hybrids
  •  Battery Charging/Discharging
  • Battery & Fuel Cell Model Analysis & Comparison
  • Calculation & Evaluation of Electrical Characteristics
  •  Energy Management
  • User Developed Control Algorithms
  • Validation of Models Against a Real System
  • Hybrid Power System Set-ups: UPS, Autonomous Power Supply, Back-up Power System, HEV/FCEV


Our LabVIEW™ based software allows users to control the hardware, system operation & set-up, gather & display data in various formats and perform data fitting for research and experimentation. Users can validate their models against a real system by using their control algorithms to set system parameters and then run real-time simulations. Acquired data can be exported to external applications such as MATLAB™ & MS Excel and many more.


  • Battery Modeling & Data Fitting
  • Hybrid Energy Management
  • Application Programming Interface (API)
