The invention discloses a multi-battery-module electric automobile power management system, and relates to the technical field of power management, the multi-battery-module electric automobile power management system comprises a battery management module and two battery modules, the energy densities of the two battery modules are different, and the two battery modules can work independently; and the power management module is used for switching two groups of lithium battery modules with different energy densities according to the state of the battery module. The battery module is designed by adopting a mode of combining the battery modules with relatively high energy density and relatively low energy density; and two groups of lithium battery modules with different energy densities are switched according to the state of the battery module through the power supply management module to supply power to the electric vehicle, so that the energy utilization rate of the battery module in a low-temperature environment is improved, and the problem of short endurance of the electric vehicle in winter is solved to a certain extent.

    本发明公开了一种多电池模块电动汽车电源管理系统,涉及电源管理技术领域,包括电池管理模块和电池模组,所述电池模组设置有两组,两组电池模组的能量密度不同且能够相互独立工作,所述电源管理模块根据电池模组的状态切换使用两组能量密度不同的锂电池模组,本发明的电池模组采用能量密度较高和能量密度较低的电池模组组合的方式设计,并通过电源管理模块根据电池模组的状态切换使用两组能量密度不同的锂电池模组对电动汽车进行供电,从而提升了电池模组在低温环境下的能量利用率,并在一定程度上解决电动汽车在冬季续航短的问题。
