Currently, the biggest impediment to the development of all-electric aircraft is the lower energy density and power density of the electric energy storage system, which cannot be compared with the traditional aircraft in terms of endurance time, load and the like. The energy consumption ratio of the existing power storage battery is far greater than the average fuel consumption rate of the fuel engine after being converted into the equivalent fuel consumption rate, and under the condition that the related parameters are equivalent to those of the traditional helicopter, the full-electric helicopter adopting the power storage battery technology has the endurance time and the range of only 1/30-1/15 of that of the traditional fuel helicopter.
The power battery of a conventional electric aircraft is one of the most central components affecting the performance of the aircraft. At present, the development of aviation high-performance power battery technology is mainly limited by the restriction of the capacity-weight ratio of the power battery and the development bottleneck of instantaneous charging technology, and the contradiction between the heavy load of the electric aircraft and the rapid electric energy loss of a power motor, and the defects of the electric system lead the performance of the electric aircraft to be generally represented by insufficient heavy load power, shorter flight time, multiple standby power batteries or one-machine-mounted multiple batteries for long voyage, longer charging time for changing the power battery and the power battery when the number of take-off and landing times is increased, and the factors seriously affect the service performance and the performance of the electric aircraft, and seriously restrict the development of the electric aircraft.
