The invention provides a vehicle-mounted double-generator power supply system, which comprises a double-silicon-generator power generation unit, a power management unit, a power management unit and an electric energy storage unit, and is characterized in that when the power management unit recognizes that the voltage of a chassis power utilization unit is lower than a set value, an input end relay is switched off to ensure that a chassis storage battery does not feed, and the power supply power management unit is switched off; the starting capacity of the storage battery is guaranteed, and the problems that when the vehicle is in a static state or high-power electricity utilization occurs, overdischarge of the chassis storage battery is caused, normal starting of the vehicle is affected, and the service life of the storage battery is shortened due to long-term overdischarge are solved; and a power supply power management unit is arranged to control power, so that the problems that when an upper load is suddenly loaded or unloaded, the system voltage is lowered or increased, part of working conditions further cause insufficient power supply of a chassis power utilization unit and impact on electric appliances of the whole vehicle, and irreversible damage is brought to the electric appliances in serious conditions are solved.
本发明提供了一种车载双发供电系统,包括双硅发发电单元、电源管理单元、电源功率管理单元和电能存储单元,通过将电源管理单元,当识别到底盘用电单元的电压低于设定值时,输入端继电器断开,确保底盘蓄电池不会馈电,保障蓄电池启动能力,解决了当车辆处于静止状态,或者大功率用电时,会导致底盘蓄电池过放电,进而影响车辆正常启动,蓄电池长期过放电寿命缩短的问题;设置电源功率管理单元控制功率解决当上装负载突然加载或者突然卸载时,会拉低或提高系统电压,部分工况还会导致底盘用电单元供电不足,冲击整车用电器,严重时会对用电器带来不可逆损害的问题。
