Abstract

The invention relates to the technical field of batteries, in particular to a multi-battery management device and an unmanned aerial vehicle. The device comprises at least two batteries, mutual charging switches, a voltage conversion module and a microprocessor; each battery is connected with the microprocessor, and is connected with the voltage conversion module through the mutual charging switches; and the microprocessor is connected with the mutual charging switches and a control end of the voltage conversion module. When the electric quantity of abnormal batteries dose not meet the storageconditions, the corresponding mutual charging switches are controlled to turn off, so that the batteries with higher electric quantity in the abnormal batteries charge the batteries with lower electric quantity, the batteries with high electric quantity cannot waste the electric power due to discharging, and additional charging power supplies are not needed to charge the batteries with low electric quantity; and as all the abnormal batteries are mutually charged, the electric energy is saved under the precondition of guaranteeing the battery storage safety, and the electric energy waste is reduced. Particularly for high-capacity batteries, the energy saving effect is prominent.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of batteries, in particular to a multi-battery management device and an unmanned aerial vehicle. Background technique [0002] When the battery is stored at a high level of power, it is easy to cause safety accidents, especially when lithium batteries are stored under high power for a long time, it will cause battery swelling, capacity decay, and even fire and other safety accidents. [0003] At present, in order to solve the problem of high battery storage capacity, the battery capacity is often monitored and the battery is discharged through a discharge circuit. [0004] In the process of realizing the present invention, the inventors found that the related technologies have at least the following problems: [0005] The method of discharging the battery through the discharge circuit causes a waste of electric energy, especially a serious waste of electric energy for a battery with la...
