The present disclosure provides a decentralized active equalization method for a cascaded lithium-ion battery pack. The method includes: connecting each battery cell in the cascaded lithium-ion battery pack to a direct current (DC) bus through an equalizer respectively, where each equalizer includes an independent controller, a sampling circuit, a power supply circuit, a drive circuit, and a main circuit; connecting an input terminal of the main circuit to a corresponding battery cell, and connecting an output terminal of the main circuit to the DC bus. The present disclosure solves the technical problem that an existing cascaded lithium-ion battery pack equalization method cannot achieve equalization when a centralized controller failure or a communication failure occurs, improves the reliability of the equalization method, can make the equalizer work at high efficiency by configuring parameters of C, K, and R, and speeds up the equalization or improves the equalization accuracy. The present disclosure uses a bus structure, which can achieve the equalization of all battery cells at the same time, thereby greatly improving the equalization speed. The present disclosure uses a modular design and can be arbitrarily configured according to the scale of the cascaded lithium battery pack, and has strong scalability.

The present disclosure discloses an automated dispensing machine adopting local coverage type sucker array and a control method thereof. The automated dispensing machine adopting local coverage type sucker array comprises a rack. A medicine obtaining device and a medicine weighing and discharging device are arranged on the rack. The control method comprises: (1), after receiving medicine grasping and discharging commands, a single-chip microprocessor firstly selects a current medicine obtaining station according to a medicine obtaining station circulation sequence, and then controls the first linear driver to push the slide to move forwards to the selected medicine obtaining station; (2), the single-chip microprocessor transmits the control signal to a fifth relay to control the second linear driver to drive the vacuum medicine sucking mechanical arm to move downwards.
