The project goal is to explore possible solutions to rebalance battery packs using advanced circuitry and modern materials such as Gallium Nitride power devices. The aim is to provide active cell balancing with high efficiency, small circuit volume and a simple modular approach so the solution can be extended for larger or differently configured battery packs.


Part of the SEND projects involves the large scale rollout of electric vehicles across the Keele University campus. Additionally, vehicle to grid technology will be utilised whereby the plugged in, charging vehicles can be used as mobile batteries for short term grid stabilisation activities. This project can contribute to this by proposing methods to greatly extend the lifespan of EV batteries.

Project progress (June 2019):

  • Literature review completed
  • Test a simple cell equalisation circuit with ideal components.
  • Measure the effects of increasing frequency with performance (equalisation speed) and component size.
  • Currently converting ideal components to accurate models of Si MOSFETS and GaN HEMTs so a direct comparison can be made.
