Abstract: A power-assisted working machine and mower. The mower includes a body including a traveling assembly and a drive motor for driving the traveling assembly; a handle device connected to the body and including an operating member, where the operating member includes a grip for a user to hold; and a connecting rod connected to the body. The mower further includes a motor parameter detection device configured to detect at least one of the rotor position and the working current of the drive motor; an angle detection device configured to detect an angle of inclination of a workplane of the mower relative to a horizontal plane; and a controller configured to estimate thrust applied to the handle device according to the rotor position and/or the working current and the angle of inclination.

Abstract: A walk-behind electric device includes a device body, a moving wheel, a moving motor, a power interface, and a control unit. The moving wheel is connected to the device body. The moving motor is configured to drive the moving wheel. The power interface is connected to a power supply so as to supply power to the moving motor. The control unit is configured to identify, according to device parameters of the walk-behind electric device, an auxiliary operation that a user wants to perform on the walk-behind electric device, where the auxiliary operation is at least partially positively correlated to at least one output parameter of the moving motor.

Abstract: A method and system for battery performance management that provides dual-equilibrium battery management based on the conditions of battery cells within the battery. Battery management is performed using a passive battery equilibrium approach until a condition within the battery is sensed whereby battery management is then performed using an active battery equilibrium approach.

Abstract: The disclosure is directed at a method and system for microgrid control. The system includes a controller that receives data from project site components and then controls the components based on the received data. The system monitors load demand and generates controls signals to control the power generating components to supply the necessary power to support load demand. The power generating components may include a battery, a solar/wind power generation device or a diesel generator.
