Herein, the need for better, more effective energy storage devices such as batteries, supercapacitors, and bio-batteries is critically reviewed. Due to their low maintenance needs, supercapacitors are the devices of choice for energy storage in renewable energy producing facilities, most notably in harnessing wind energy.
Therefore, to improve charging efficiency and user experience, ensure charging safety and battery lifespan, establishing and selecting scientific charging strategies for safe, efficient, and stable charging is crucial in accident prevention. Traditional fast charging methods usually entail charging the battery with high currents.
More and more researchers are exploring fast charging strategies for LIBs to reduce charging time, increase battery longevity, and improve overall performance, driven by the growing popularity of EVs. Nevertheless, fast charging poses challenges such as energy wastage, temperature rise, and reduced battery lifespan.
Specifically, by integrating advanced algorithms such as adaptive control and predictive control, it is possible to accurately adjust the current changes during the charging process, ensuring that the current distribution and duration of each stage reach an optimized state, thereby improving charging efficiency and battery life.
When establishing design standards based on charging time, it is crucial to consider the safety and reliability of batteries. Insufficient charging time can result in incomplete charging or battery damage due to excessive charging current, leading to a chemical imbalance within the battery.
While CC-CV charging is a common method with relatively high charging efficiency, it may pose the risk of overcharging for smaller capacity batteries, requiring strict control over the values of CC and CV. The MSCC charging strategy can effectively extend battery life, and reduce the risks of overcharging and overdischarging.
When exploring optimization strategies for lithium-ion battery charging, it is crucial to thoroughly consider various factors related to battery application characteristics, including temperature management, charging efficiency, energy consumption control, and charging capacity, which are pivotal aspects.
