摘要： The present system and method manage a rechargeable battery comprising two or more battery cells or series stacks of cells. The system includes a set of switches, each of which connects a cell or stack of cells between positive and negative nodes when actuated, or connects one cell in a stack of cells to another cell in the stack when actuated, such that when all the switches in a given stack are actuated, it is connected between the positive and negative nodes. An electrical load is directly connected to the positive and negative nodes. A controller determines the state of each cell or stack of cells by measuring and/or calculating one or more predetermined characteristics, and selectively actuates the switches based on the states of the cells or stacks of cells so as to enhance the life of the battery.
