METHOD, SYSTEM AND DEVICE FOR POWER CELL MANAGEMENT

摘要

A power management device for an electrically powered apparatus includes a plurality of cell management circuits and a controller. Each cell management circuit includes a set of terminals to receive one power cell; a boost converter connected to an output of the terminals; and an energy storage component selectively connected to one of an output of the boost converter, for receiving and storing energy from the boost converter, and an output of the cell management circuit, for delivering energy to the apparatus. The controller is configured, for each cell management circuit, to: obtain a cell output level; based on the cell output level, select a boost output level for the boost converter; and alternately connect the energy storage component to the boost converter output to collect energy from the boost converter at the boost output level, and the management circuit output to deliver the energy to the apparatus.
