WebThe 16-Cell Lithium-Ion Battery Active Balance Reference Design describes a complete solution for high current balancing in battery stacks used for high voltage applications like xEV vehicles and energy storage systems. The design implements active cell balancing to compensate for both cell charge mismatch and cell capacity mismatch and obtain the WebThe 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. such a funny life
