The invention discloses an emergency power supply system for an unmanned helicopter, and relates to the field of unmanned helicopters. The invention provides an integrated emergency power supply system for an unmanned helicopter. The system comprises a lithium battery pack, a battery management system module and a battery charging module, the lithium battery pack is an energy storage center of the whole system, and when a main power supply of the unmanned helicopter fails, energy is output; the battery management system module is responsible for detecting battery working states such as the single voltage, total voltage, charging and discharging current, temperature and the like of the battery, estimating SOC/SOH parameters of the battery after data processing, and controlling actions such as charging and balancing of the battery; the battery charging module converts a direct-current voltage source input by a bus of the unmanned helicopter into a stable constant-current voltage-limiting source to charge a battery.

    本发明公开了一种无人直升机用应急电源系统,涉及无人直升机领域。提出了一种将集成式式无人直升机用应急电源系统。该系统包含锂电池组、电池管理系统模块和电池充电模块三个部分:锂电池组为整个系统的能量储存中枢,当无人直升机主电源故障时,输出能量;电池管理系统模块负责检测电池的单体电压、总电压、充放电电流、温度等电池工作状态,并经过数据处理后对电池的SOC/SOH参数进行估计,并控制电池充电、均衡等动作;电池充电模块将无人直升机母线输入的直流电压源转换为稳定的恒流限压源为电池进行充电。
