STMicroelectronics AEK-POW-BMSHOLD Battery Holder contains a maximum of 14 cells, all connected in series, and a dedicated slot and connector for the AEK-POWBMS63EN board. The AutoDevKit ecosystem has been extended to include a specific cylindrical battery holder to support fast evaluation and meet stringent time-to-market for BMS solutions. The purpose of this extension is to quickly create a battery pack to evaluate the ST BMS solution based on the AEK-POW-BMS63EN analog front-end node hosting the L9963E and the AEK-COM-ISOSPI1 ISOSPI transceiver hosting the L9963T.
To build a complete battery pack in centralized or dual-ring topologies, the user can stack up to three/four AEK-POW-BSMHOLD kits (the limit is the stackable weight). A separate bag inside the kit package contains six M3x12mm pan steel screws, four M3x25mm, plus six M3x30mm hexagonal steel spacers. These elements can be used to mount another AEK-POW-BMSHOLD layer.
The STMicroelectronics AEK-POW-BMSHOLD has a long satin ribbon tied to a buttonhole on the plexiglass used to support easy battery removal. The kit supports INR 18650 battery types. The estimation of SoC and SoH included in AutoDevKit Studio is computed through an extended Kalman filter with characterization data coming from INR 18650 MJ1 batteries by LG.
