Abstract: A method is provided for managing an unmanned aerial vehicle (UAV). The UAV includes a first cell unit and a second cell unit connected in parallel. The method includes: detecting, by a first control circuit, whether a failure occurs in the first cell unit; detecting, by a second control circuit, whether a failure occurs in the second cell unit; establishing a communication between the first control circuit and the second control circuit; and in response to detecting a signal indicating that a failure occurs in the first cell or the second cell from the first control circuit or the second control circuit, reducing an output power of a propulsion device of the UAV.

Abstract: A battery includes a first cell unit, a first control circuit electrically connected with the first cell unit, a second cell unit connected with the first cell unit in parallel, and a second control circuit electrically connected with the second cell unit. The first control circuit is configured to disconnect an electrical connection between the first cell unit and a power output terminal of the first control circuit in response to a failure of the first cell unit. The second control circuit is configured to disconnect an electrical connection between the second cell unit and a power output terminal of the second control circuit in response to a failure of the second cell unit.
