Research Interests

High energy and power batteries are critical for the next generation of clean energy grid and transportation technologies

  • They store energy from renewables like Solar and Wind then make it available later when needed.
  • Batteries can dispatch energy in a blink, so they let the grid and transportation operate at maximum efficiency.

 

Professor Subramanian’s model and software will make next generation batteries

  • Safer
  • Have higher energy storage capacity
  • Recharge faster
  • Last longer

 

Professor Venkat Subramanian’s research and educational interests are at the confluence of electrochemistry, electrochemical engineering, applied mathematics and systems engineering. His current research interests are summarized below.

  • Model reformulation for increased computational efficiency
  • Battery management system (BMS) using physics based efficient reformulated models
  • Nonlinear model predictive control lab for lithium-ion batteries
  • Design of new electrode materials for lithium-ion batteries
  • Reliability, system level integration and control of batteries for renewable grids
  • Electrochemical and energy systems engineering
  • Multiscale simulation and design of energetic materials
  • Understanding AC impedance data using detailed physics based models
