Battery Cell Balancing: What to Balance and How
battery pack for particular device. The means used to perform cell balancing typically include by-passing some of the cells during charge (and sometimes during discharge) by connecting external loads parallel to the cells through controlling corresponding FETs. The typical by-pass current ranges from a few milliamps to amperes. A difference in cell voltages is a most typical …
