Abstract: A vehicle includes a battery management chip and a battery management system. The battery management chip comprises a battery cell data sampling module, a data processing module, a first communication module and a first power module. The battery cell data sampling module is used for acquiring battery cell data of a battery cell; the data processing module is connected to the battery cell data sampling module and used for processing the battery cell data; the first communication module is connected to the data processing module and used for sending the processed battery cell data to a control module; and the first power module is connected to the battery cell and the data processing module and used for receiving an initial voltage outputted by the battery cell, and performing boost processing on the initial voltage, so as to provide an operating voltage for the data processing module.
