The invention belongs to the technical field of battery management, and discloses an electric vehicle battery management system. Comprising a state information acquisition module, a correction module, a load information acquisition module, a residual electric quantity estimation module, a charge and discharge control module, a battery equalization management module, a state detection module, a life prediction module, a fault early warning module, an interrupt protection module, a data transmission module and a display module. According to the invention, when one state data is abnormal or the battery has a fault, early warning and terminal connection can be carried out in time, the safety of battery protection is improved, and overcurrent protection, over-temperature protection and over-discharge protection of the electric vehicle battery are realized. Related information and the current state of the electric vehicle battery can be monitored, the condition of the electric vehicle battery can be mastered in time, and fault reasons can be found out conveniently after the electric vehicle battery breaks down. The system is diversified in function, is high in safety, can achieve the timely early warning and guarantee, and can comprehensively, objectively and accurately reflect the current state of the battery.
