The invention discloses an electric vehicle battery management system. The system comprises a motor for driving an electric vehicle to run, a first battery pack and a second battery pack which are respectively connected with the motor and are used for supplying power to the motor, a motor monitoring module used for collecting motor vibration data and instantaneous rotating speed, a whole vehicle monitoring module used for collecting the vehicle running speed, the road surface gradient, the environment temperature and the remaining electric quantity of the first battery pack and the second battery pack, a main control computer used for receiving the detection data of the motor monitoring module and the whole vehicle monitoring module and controlling the first battery pack and the second battery pack to work, wherein the first battery pack is a high-capacity battery, and the second battery pack is a high-power battery. The invention further provides an electric vehicle battery managementmethod, when the electric vehicle runs, working states of the first battery pack and the second battery pack are determined based on the BP neural network. Through cooperative use of the two batterypacks, the endurance time is long, and power is sufficient.

    本发明公开了一种电动汽车电池管理系统,包括:电机,用于驱动电动汽车行驶;以及第一电池组和第二电池组,其分别与所述电机连接,用于为所述电机供能;电机监测模块,其用于采集电机振动数据和瞬时转速;整车监测模块,其用于采集车辆行驶速度、路面坡度、环境温度以及第一电池组和第二电池组的剩余电量;主控机,其用于接收所述电机监测模块和整车监测模块的检测数据并控制第一电池组和第二电池组工作;其中,所述第一电池组为高容量电池,所述第二电池组为高功率电池。本发明还提供一种电动汽车电池管理方法,当电动汽车行驶时,基于BP神经网络确定第一电池组和第二电池组的工作状态。通过双电池组配合使用,续航时间长且动力足。
