A method for in-situ treatment of sediment simultaneous with microbial electricity generation is provided, comprising steps of constructing a microbial fuel cell, placing the microbial fuel cell in the sediment, forming a cell circuit, and cultivating microorganisms to generate electrical power. Two ends of the FBG are connected to an optic fiber for signal transmission. The hardware encoder is configured by hardware dedicated to the encoding and encodes a portion of AV data. The housing can be a candy bar phone style housing. The engine torque component is determined based on an engine torque and a torque transfer capacity margin allowance for the engine torque when the drive wheel is driven at least by the motorgenerator. The DCDC converters are connected to each other in series on their output side, and the low-pass filter is post-connected to the DCDC converters that are connected in series to each other, so as to smooth the output voltage generated by the DCDC converters at their output side.
