1.3 Aquion Products

Battery Stack: Smallest unit of Aquion’s Aqueous Hybrid Ion (AHITM) batteries. In most cases, battery stacks must be connected to a SMI-100 to be monitored by a BMS-200.

Battery Module: Twelve palletized battery stacks pre-wired in parallel. Battery modules have an integrated sensing board that measures the voltage, current, and temperature of the battery and relays that data to the BMS-200.

Stack Monitoring Interface (SMI-100): Enclosed sensing board that measures the voltage, current, and temperature of battery stacks and relays that data to the BMS-200.

Battery Monitoring System (BMS-200): System that parses and processes the data from the battery module sensing board or the SMI-100. The BMS-200 then stores the processed data for access by the site controller on request.
