Abstract
This article presents a method to control the
current of each battery cell in a serially connected battery
stack according to each cell capacity. With this method
battery cells with different capacities and even battery
cells with different chemistries can be serially connected.
Therefore, significantly more energy can be extracted from
the battery stack and a second-life-option for old batteries
with a large capacity variation is possible.
The required power converter structure as well as the
calculation of the individual cell currents are presented.
A simulation of the power converter is performed and
validated by a prototype with twelve serially connected
battery cells.
