Performance Evaluation of Charging Techniques for Lithium-Ion Batteries

As electric vehicles (EVs) continue to gain widespread use, enhancing battery charging efficiency and minimizing deterioration have become key priorities. The charging patterns of the EV battery substantially impact charging time and battery deterioration. This paper assesses various charging techniques for Lithium-ion (Li-ion) cells, focusing on key parameters such as current, terminal voltage, state of charge (SoC), and temperature variation over time. The charging techniques analyzed include constant current-constant voltage (CC-CV), boost charging, constant power-constant voltage (CP-CV), constant temperature-constant voltage (CT-CV), pulse charging, and sinusoidal ripple charging (SRC). These methods were simulated under identical conditions to evaluate their impact on charging time and temperature rise. This paper offers critical insights into optimizing battery charging, enhancing performance, and extending battery longevity by evaluating the efficacy of various strategies.
