The invention discloses a low-voltage power supply device of an electric aircraft, which comprises a high-voltage battery. The high-voltage battery is mounted in the electric aircraft, and a high-voltage-to-low-voltage DCDC is mounted in the electric aircraft; the APU battery is mounted in the electric aircraft, and a low-voltage load is mounted in the electric aircraft. According to the low-voltage power supply device of the electric aircraft, aiming at the characteristics of low load and small weight margin of a small electric aircraft, the weight of a bearing component in the electric aircraft needs to be reduced, and the design thought of double power supplies and double low-voltage power converters is adopted, so that the low-voltage power supply system or the DCDC power converter can still work normally after a single-point fault occurs; and the safety of the electric aircraft is improved.
本发明公开了一种电动飞机的低压供电装置,包括高压电池,所述高压电池安装在电动飞机的内部,且电动飞机的内部安装有高压转低压DCDC;APU电池,所述APU电池安装造电动飞机的内部,其中电动飞机的内部安装有低压负载。该电动飞机的低压供电装置,针对小型电动飞机由于其载荷低、重量余量小的特点,需要降低电动飞机内部承载构件的重量,同时采用双电源,双低压功率转换器的设计思路,确保低压供电系统或DCDC功率转换器出现单点故障后,仍可以正常工作,增加电动飞机的安全性。
