This paper describes a stackable battery monitoring and management integrated circuit for EVs. Owing to the number of cells in the series, the amount of data transmitted by the BMS is significant. The integration of digital control and registers in the BMIC is necessary for the efficient execution of each function.
Fig. 14 illustrates a summary of the power consumption of the battery management chip. The battery management chip consumes 0.838 μA of quiescent current, and its power down current is less than 10 nA. The two current detection circuits and bandgap circuits consume almost more than half of the power.
