Abstract: A method, system and device for active balance control of a battery pack are disclosed. The method includes: calculating a reference balance current ratio of a battery cell to a battery pack in each batch; calculating an actual balance current ratio of the battery cell to the battery pack at each moment in any batch; allowing the actual balance current ratio to track the reference balance current ratio of the corresponding batch in real time by executing a preset tracking algorithm; and performing balance control on the battery pack according to a tracking result. The system includes a first calculation module, a second calculation module, a tracking module, and a balance control module. The device includes a memory and a processor.

Abstract: This invention relates to a method and apparatus for the control of injection molding and, in particular, for determining a suitable time for transfer from injection velocity control to packing pressure control. The invention uses a derivative of, preferably the nozzle pressure, and inputs this to a fuzzy inference system. The fuzzy inference system uses said rules and knowledge to provide a suitable transfer time as an output. It is preferred that the sample pressure is filtered prior to calculation of the derivative.
