Improvement of Li-ion Battery Active Balancer Using PI-Controller
Abstrak
This paper presents simulation and design for the improvement of Li-ion battery ac-tive balancer using PI controller. The growing market for lithium ion (Li-ion) battery cells has made a positive impact towards electrical energy storage (EES) system throughout the advancing technological and scientific world. Balancing in a battery pack has become a main priority to avoid over-charging and over-discharging while also improving the Li-ion battery life. Unlike passive balancing, active balancing transfers the energy from one cell to another or controls the cell’s output, thus improving its efficiency. This paper presents how previous work was accomplished by many scholars in order to avail themselves of the active balancing project. A cell model was shown in this paper that was built based on energy transfer circuit theories. A capacitor(C), inductor (L), MOSFET (M) and Diode (D) were used in the circuit build in order to balance the cells of different State-of-Charge (SOC). A PI controller was added with circuit to improve the voltage efficiency. After adding PI controller, the voltage balance of the cell was seen improved.
