The invention provides a power battery management system and a power supply control method thereof. The power battery management system comprises a BMU, a plurality of power battery modules and CSCs corresponding to the power battery modules. Each CSC comprises a first DC/DC and a second DC/DC, wherein the input end of the first DC/DC and the input end of the second DC/DC are both connected with the positive electrode and the negative electrode of the corresponding power battery module so as to take electricity from the power battery module, the output end of the first DC/DC is connected with the input end of the corresponding CSC and used for supplying power to the CSC, and the output end of the second DC/DC is connected with the input end of the BMU and used for supplying power to the BMU. Due to the adoption of the technical scheme, the power battery modules can serve as the only power supply for power battery systems, the size and weight of an electric automobile are reduced, and the cost of the electric automobile is reduced.
