EVAL-ADBMS1818Z

EVAL-ADBMS1818Z demonstration circuit is a multicell battery stack monitor featuring the ADBMS1818, an 18-cell monitor on the board. Multiple boards can be linked through a 2-wire isolated serial interface (isoSPI) to monitor any number of cells in a stack. The demo circuit also features reversible isoSPI enabling a fully redundant communication path. IT can communicate to a PC by connecting directly to a DC2026 Linduino® One. The DC2026 must be loaded with the appropriate program (called a “sketch”) to control the battery stack monitor IC and receive data through a USB serial port. ADBMS1818 suitable for most battery chemistries. Multiple ADBMS1818 devices can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings. The ADBMS1818 can be powered directly from the battery stack or from an isolated supply.
