According to the power management system for the long-endurance unmanned aerial vehicle, autonomous balance control can be achieved, and it is ensured that the actual output voltage and/or current of the power management system are/is constant. The power supply management system comprises a power supply input module, a power supply transmitting module, a power supply output module and a power supply detection and control module, and the power supply transmitting module comprises a primary transmitting unit and a secondary transmitting unit. On the premise of ensuring that the actual output voltage and/or current of the power supply management system is constant, the discharge capacity of each battery pack is autonomously balanced, and constant current and/or voltage are output to the secondary transmitting unit, so that the battery pack with lower electric quantity is prevented from being damaged due to over-discharge, the use efficiency of the battery pack is improved, the service life of each battery pack is prolonged, and the power supply management system is suitable for popularization and application. Meanwhile, the effective endurance flight time of the unmanned aerial vehicle is prolonged to the maximum extent.

    本发明提出了一种用于长续航无人机的电源管理系统,能够实现自主均衡控制,并且确保电源管理系统实际输出电压和/或电流恒定不变。本发明电源管理系统包括电源输入模块、电源变送模块、电源输出模块以及电源检测与控制模块,其中所述电源变送模块包括一级变送单元和二级变送单元,在确保电源管理系统实际输出电压和/或电流恒定不变的前提下自主均衡各电池组的放电量,输出恒定电流和/或电压到二级变送单元,避免电量较低的电池组因过度放电而造成损坏,提高电池组的使用效率,延长了各电池组的使用寿命,同时最大程度上提高无人机的有效续航飞行时间。
