This application relates to a battery management system and a power supply device. The battery management system includes a first battery management module and a second battery management module in communication connection with the first battery management module. The second battery management module includes a code detection circuit that includes a plurality of sampling channels. The first battery management module is configured to determine code data based on voltage of at least one of the sampling channels, and perform identity authentication on the second battery management module based on the code data. The code detection circuit is disposed in the second battery management module, and code data is determined based on voltage of the sampling channel in the code detection circuit, so that failure in any battery management module does not affect code data collection by other battery management modules, thus achieving a high management reliability.
