Description

The image shows a detailed block diagram of a Battery Management System (BMS). It consists of several components: a battery (BAT) connected to input filtering resistors (Rin) and capacitors (Cin). This input stage feeds into several VC voltage control inputs (VC6, VC5, VC4, VC3, VC2, VC1, VC0). There is also a VREF, Vtab and VOUT lines. A section showing ADC Reference and the micro controller (MCU) connections including I2C, GPIO and VSS. Finally the image illustrates the current sensing circuit with many RSENSE resistors, and the the output section.
