Brief description of the project:

Battery storage systems are becoming more and more prevalent as we move towards a distributed energy system and the electrification of transport. One of the issues facing large battery packs like the ones found in the Nissan Leaf is that the individual cells within the battery pack become out of balance with each other. This causes problems with charging, discharging, the total capacity or range of the battery pack, plus life expectancy of the battery pack.

The project goal is to explore possible solutions using advanced circuitry and modern materials such as Gallium Nitride power devices. 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.
