Design of Bipolar, Flowing Electrolyte Zinc-Bromine Electric Vehicle Battery System

The integration of bipolar, flowing electrolyte zinc-bromine technology into a viable electric vehicle battery system requires careful analysis of the requirements placed on the battery system by the EV power train. An analysis of the influence of these factors on zinc-bromine EV battery system design has been carried out for two types of EV propulsion systems. The first of these is a nominal 100V dc system, while the second is a high voltage (200V dc) system as might be used with an advanced design ac propulsion system. Based on these studies, low profile, 12 dm² bipolar cell components have been developed which are readily incorporated into a variety of motive power and stationary energy storage system designs.
