In the X-Series BMS, The X-MCUP controllers manage battery cells directly, while the X-BCU provides total system monitoring and control. Each X-MCUP supports a single cell bank of 4-12 cells in series.

Originally developed for use in electric buses, the X-Series BMS’s patent pending expandable design is best suited for medium to high voltage lithium-ion battery packs and is highly configurable for many different applications. Features include isolated CAN bus communications, support for up to 240 cells, and automatic configuration of X-MCUP modules upon connection to the X-BCU master.

To learn more about this controller, see our X-Series overview or download the X-MCUP data sheet.
