Control Strategy for Lithium Batteries Balancing Circuit

Lithium cells (e.g. LiPol, LiFe, LiIon) are the root component of the power supply for mobile robots and electric vehicles. However, they are very sensitive to overvoltage and undervoltage. This article proposes a control system for balancing the voltage of the lithium cells during the charge and discharge of the accumulator. The proposed circuit including the control algorithm has been verified and optimized by simulation using MATLAB / Simulink environment.
