Abstract: The present disclosure discloses a servo motor and an encoder calibration method. The encoder calibration method includes: calculating a gain error, an offset error and a phase error, by an error calculation block, according to a first signal and a second signal output by an encoder; calculating at least one gain calibration parameter, at least one offset calibration parameter and at least one phase calibration parameter, by the error calibration block, according to the gain error, the offset error and the phase error; and calibrating sequentially, by the encoder, the gain, the offset and the phase of the first signal and the second signal according to the at least one gain calibration parameter, the at least one offset calibration parameter and the at least one phase calibration parameter, wherein performing at least one gain calibration and offset calibration after the phase calibration is completed.

Abstract: A battery management system and method are provided. The battery management system includes a plurality of battery devices, wherein each of the battery devices is connected in parallel. Each of the battery devices includes one or a plurality of battery cells which is configured to provide power, a switch circuit, and a controller which is configured to detect a reverse current. When the controller detects the reverse current, the controller will disable the switch circuit and enable a judgment mechanism to determine whether to re-enable the switch circuit.
