A battery cell management and balance circuit comprises multiple battery cell balance circuits, multiple battery cell monitor units, multiple battery module balance circuits and a battery management unit. The battery cell balance circuits connect to battery cells for executing a first charge or discharge command. The battery cell monitor units monitor battery cells for generating battery cell information and the first charge or discharge commands. The battery module balance circuits connect to battery modules for executing second charge or discharge commands. The battery management unit connect to the battery cell monitor units for receiving battery cell information and the battery module balance circuits for direct or indirectly generating the second charge or discharge commands to the battery module balance circuits. A battery system and a battery cell management and balance circuit method is also introduced.
