Novel MMC control for active balancing and minimum ripple current in series-connected battery strings

Abstract:

The performance of a string of series-connected batteries is typically restricted by the worst battery cell in the string and a single failure point will render the entire string unusable. To address these issues, we present a decentralised battery management system based on a modular multilevel converter (MMC) with a distributed inductor. This novel MMC design enables each MMC cell to operate autonomously, without central control, by sensing the local inductor voltage. Batteries are load...
