The solution uses one AFE (NXP MC33772CTP2AE). The MC33772C is a battery control IC designed for automotive and industrial applications. It supports up to six battery strings, analog-to-digital conversion of differential battery voltage (up to 256 average levels to ensure measurement accuracy), current acquisition, and also includes coulomb counting and temperature measurement functions.

This solution is a battery monitoring unit CMU in the energy storage high-voltage battery management system based on NXP S32K118 and MC33774. The single board can monitor up to 54 battery strings and 12 temperature data. It adopts CAN-BUS architecture, and S32K118 and MC33774 use isolated SPI for communication.
