We have recently completed proof of concept testing with a unique flow cell system in tandem with VIS/NIR spectrometry that has demonstrated improved accuracy in SOC evaluation and expanded data for VRB battery applications. Our solution is based on a full visible spectrum analysis, and provides significantly more information than the legacy systems in current use.
The full spectrum results derived from this probe is unique, allowing the analysis of all relevant wavelengths at once. Analysis limited by filtered wavelength ranges may not detect slight variations in chemistry, where this new offering acquires and analyzes the entire spectrum for each acquisition. Full spectrum measurements allow for the accurate determination of the charge state including small spectral changes due to temperature or varying electrolyte solutions to be calibrated and reported in real-time.
Deployment of VRB batteries in grid applications demand accurate SOC measurement to determine differentials in peak usage discharge and off-peak recharge as a matter of economical viability. Full spectrum analysis allows for tracking SOC at all levels, temperatures, and with chemical variables present in the electrolyte solutions.
This solution provides remote maintenance and referencing capabilities along with a unique application specific measurement and calibration interface which eliminates downtime set aside for those purposes. Data acquisition can be remotely acquired and stored in real time on recirculating process fluids, which allows for optimal control across multiple installations.
