Problems solved by technology
[0002] Existing electric aircraft usually provide power through a battery or a group of batteries (composed of several batteries connected in parallel and in series). When any one of the batteries fails (such as a short circuit), the entire group of batteries will stop power output, making As a result, the entire aircraft lost power and could not fly normally
For fixed-wing aircraft, an emergency landing can be achieved by gliding, but for multi-rotor aircraft, it will mean extreme danger

The invention relates to a feedback control method and device of a multi-rotor manned craft power supply. The method comprises the steps of acquiring battery information of each battery unit group ina power supply system, wherein at least two battery unit groups are contained in the power supply system and are connected in parallel to a power bus; judging whether each battery unit group is abnormal or not according to the battery information; and controlling to disconnect the battery unit group and the power bus if an arbitrary battery unit group is abnormal. By the method, flexible control of each battery in the multi-rotor manned craft power supply can be achieved, and an aircraft is prevented from losing power due to a certain battery fault.
Description
technical field [0001] The invention relates to the field of power supply technology, in particular to a feedback control method and device for a power supply of a multi-rotor manned aircraft. Background technique [0002] Existing electric aircraft usually provide power through a battery or a group of batteries (composed of several batteries connected in parallel and in series). When any one of the batteries fails (such as a short circuit), the entire group of batteries will stop power output, making As a result, the entire aircraft lost power and could not fly normally. For fixed-wing aircraft, forced landing can be achieved by gliding, but for multi-rotor aircraft, it will mean extreme danger. Contents of the invention [0003] Based on this, the present invention provides a feedback control method and device for a power supply of a multi-rotor manned aircraft, which can realize flexible control of each battery in the power supply system of the multi-rotor manned aircr...
