The invention discloses a battery management system of a new energy automobile, which comprises a suspension module, a circuit switching module, a main battery pack, a standby battery pack, a monitoring module and a switching module, and is characterized in that the suspension module is used for suspending the main battery pack and bearing the standby battery pack; the circuit switching module is used for supplying power to an automobile power system when the electric energy of the main battery pack and the electric energy of the standby battery pack are different, the monitoring module is used for monitoring the main battery pack on the hanging module, and when the main battery pack is on fire, high temperature or smog, the hanging module releases the main battery pack downwards. According to the invention, by arranging the monitoring module, the suspension module, the switching module, the circuit switching module, the main battery pack and the standby battery pack, when the monitoring module monitors that the main battery pack is abnormal, the switching module is controlled to switch the standby battery pack to supply power to an automobile power system through the circuit switching module, and meanwhile, the suspension module releases the abnormal main battery pack; therefore, the abnormal main battery pack is prevented from damaging the whole automobile.

    本发明公开了一种新能源汽车的电池管理系统,包括悬挂模块、电路转接模块、主电池包、备用电池包、监测模块和切换模块,所述悬挂模块用于悬挂主电池包和承载备用电池包,所述电路转接模块的作用是将主电池包和备用电池包的电能不同时向汽车动力系统供电,所述监测模块用于监测悬挂模块上的主电池包,当主电池包出现起火、高温或者烟雾时,悬挂模块向下释放主电池包。本发明中,通过设置监测模块、悬挂模块、切换模块、电路转接模块、主电池包和备用电池包,监测模块监测的主电池包异常时,控制切换模块切换备用电池包通过电路转换模块向汽车动力系统供电,同时悬挂模块释放异常的主电池包,使其和汽车分离,避免异常的主电池包损毁整个汽车。
