The invention provides an automobile energy management system which is characterized in that the alternating current sides of a primary side module, a secondary side high-voltage module and a secondary side low-voltage module are respectively connected with the primary side, the secondary side high-voltage side and the secondary side low-voltage side of a transformer module, and a motor module, a motor controller module and an auxiliary conversion module are sequentially connected and then connected to the direct current side of the primary side module; two ends of the power supply module are respectively connected with AC sides of the motor module and the auxiliary conversion module, AC-DC conversion can be realized through the motor module, the motor controller module and the auxiliary conversion module, and a power factor correction link in a traditional charger is replaced. The high-voltage battery pack is connected with the direct-current side of the secondary high-voltage module and the direct-current side of the motor controller through the first relay set and the second relay set, and the low-voltage battery pack is connected with the direct-current side of the secondary low-voltage module. The working mode of the automobile energy management system can be controlled by controlling the opening and closing states of the relays of the first relay set and the second relay set so as to flexibly achieve energy management of the whole automobile.

    本发明提供了一种汽车能量管理系统,原边模块、副边高压模块及副边低压模块的交流侧分别连接变压器模块的原边、副边高压侧和副边低压侧,将电机模块、电机控制器模块及辅助变换模块依次连接后连接至原边模块的直流侧,电源模块的两端分别连接电机模块及辅助变换模块的交流侧,通过电机模块、电机控制器模块及辅助变换模块可共同实现交直流转换,替代传统充电机里的功率因数校正环节,且高压电池组分别通过第一继电器组及第二继电器组连接副边高压模块及电机控制器的直流侧,低压电池组连接副边低压模块的直流侧,通过控制第一继电器组及第二继电器组的继电器的开闭状态即可控制汽车能量管理系统的工作模式,以灵活实现整车能量管理。
