Abstract

Disclosed are a control method, a control system, and a storage medium of a battery pack, and an unmanned aerial vehicle, wherein the battery pack includes at least two parallelly-connected parallel batteries, the control method comprising: obtaining an operating state parameter of the parallel batteries; according to the operating state parameter, controlling a control switch connected to the parallel batteries to perform corresponding operation so as to control the discharge sequence of the at least two parallel batteries. According to the technical scheme, the operating state parameter of the parallel batteries is obtained, and according to the operating state parameter, a switch is controlled to perform corresponding operation, so that the discharge sequence of the at least two parallel batteries is controlled. The fact that the parallel batteries do not form electro-charging overflow on other parallel batteries in an electro-discharge process is ensured, so that the operation stability of battery cores of the parallel batteries is ensured, and the safety and reliability of operation of an unmanned aerial vehicle is guaranteed. The practicability of a battery pack control method is improved, and the method is beneficial for popularization and application in the market.
