    Lithium-ion battery (LiB) technology is extensively used in energy storage systems (ESS), electric vehicles, and portable devices. Optimal cell balancing techniques for a battery management system are essential for the operation of the Li Battery. This paper proposes a new passive and active-based hybrid cell balancing technique integrating switched resistor balancing technique and switched capacitor balancing technique to achieve less balancing time and less power dissipation with simple control and hardware. The proposed system has been mathematically modeled and simulated, and the results show a 30% increase in the balancing time compared to the conventional capacitive balancing technique. Also, the control algorithm can adaptively operate to achieve better performance of the circuit. The simulation is done in the MATLAB Simulink environment.
