An enhanced fast-charging strategy can overcome these limitations. This work proposes a novel fast-charging strategy to charge lithium-ion batteries safely. This strategy contains a voltage-spectrum-based charging current profile that is optimized based on a physics-based battery model and a genetic algorithm.
Thanh et al. proposed a fast charging strategy that successfully charges Lithium-Ion Polymer Battery (LiPB) at different initial charge states and can rapidly charge the same type of LiPB under varying capacities and cycle lives. Table 2.
Traditional fast charging methods usually entail charging the battery with high currents. Nonetheless, prolonged high-current constant charging can cause a progressive rise in battery temperatures. Excessive temperature can shorten the lifespan of LIBs, leading to decreased battery performance and driving range .
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.
The application characteristics of batteries primarily include temperature, charging time, charging capacity, energy consumption, and efficiency. The MSCC charging strategy effectively prevents overheating of the battery during the charging process by controlling the charging current.
We anticipate that this discovery could pave the way to the development of new fast recharging battery technologies. Here the authors show that illumination of a lithium manganese oxide cathode can induce efficient charge-separation and electron transfer processes, thus giving rise to a new type of fast lithium-ion battery charging.
