Zusammenfassung:	A battery control method, a battery system and a power supply system, the control method comprising: acquiring a first voltage and a second voltage, the first voltage being the voltage of a first battery module, the second voltage being the voltage of a second battery module, the first battery module being electrically connected with the second battery module, the first battery module being different in capacity from the second battery module; and according to the voltage difference between the first voltage and the second voltage, the working mode of the DCDC converter is controlled, the DCDC converter is electrically connected with the second battery module, and the DCDC converter is used for controlling the input or output power of the second battery module. According to the embodiment of the invention, a new battery module with a capacity different from that of an original battery module can be merged into the battery system, and the capacity expansion of the battery system can be carried out more conveni
