The cell balancing module comprises an interface (SPI, VrefH, VrefL) to input a coded reference voltage (Vref) and input nodes (In1, . . . , InN) for connecting a stack of energy storage cells (BAT1, . . . , BATn). A switching unit (SW) is connected to each of the input nodes (In1, . . . , InN) and a local balancing unit (loc) coupled to the switching unit (SW) and the interface (SPI, VrefH, VrefL). The local balancing unit (loc) is designed to compare the coded reference voltage (Vref) with cell voltages (VBAT1, . . . , VBATn) of the stack of energy storage cells (BAT1, . . . , BATn) to be connected and to charge balance the stack of energy storage cells (BAT1, . . . , BATn) to be connected depending on the comparison of coded reference voltage (Vref) and cell voltages (VBAT1, . . . , VBATn).
