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

Abstract

A power management system for a multirotor manned aerial vehicle and the aerial vehicle. The power management system comprises at least two sets of battery units (BMU1-BMU8). The at least two sets of battery units (BMU1-BMU8) are connected in parallel. Each set of the battery units (BMU1-BMU8) comprises batteries (BAT1-BAT8), fuses (F1-F8) used for overcurrent protection, and relays (k1-k8) used for controlling the set of battery units (BMU1-BMU8) to disconnect when the set of battery units (BMU1-BMU8) is abnormal. Power output control can be implemented for the multirotor manned aerial vehicle, thus preventing the aerial vehicle from losing power due to failure of any one battery.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power supply management system of a multi-rotor manned aircraft and the 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 power management system of a multi-rotor manned aircraft, which can realize the output control of the power supply of the multi-rotor manned aircraft, and prevent the aircraft from losing power due to a...
