The invention provides an
energy management method considering a single push failure characteristic, and belongs to the technical field of
energy management, and the method comprises the steps: building an unmanned aerial vehicle
hybrid battery system model with a
hydrogen fuel battery as a main power supply and a
lithium ion battery as an auxiliary power supply; and a power following
management strategy is established, single-source
fault tolerance of the fuel
cell is combined with an equivalent
hydrogen consumption minimum strategy, and the output power of the fuel
cell and the
lithium battery is controlled according to the SOC state to improve the fuel economy of the
hybrid battery system and ensure the reliable power supply of the
hybrid battery system. The
lithium battery is prevented from being overcharged or overdischarged while the load power supply is ensured, and the instantaneous equivalent minimum
hydrogen consumption of the hybrid battery
system is solved, so that the optimal
energy distribution of the
system is realized, and the reliable power supply of the
system is ensured. According to the method, the situation of single-source faults is considered, system
energy management based on the ECMS is carried out, the economical efficiency is effectively improved, meanwhile, reliable power supply of the
hybrid power system is guaranteed, and good performance is achieved.
