As the charging rate increases, the faster the active material reacts, the faster the battery voltage increases, and the energy loss generated increases. Therefore, the actual charging capacity of the Li-ion battery with high current charging is lower than the charging capacity when charging with low current.
The expanding use of lithium-ion batteries in electric vehicles and other industries has accelerated the need for new efficient charging strategies to enhance the speed and reliability of the charging process without decaying battery performance indices.
Boost charging will, therefore, not negatively impact lithium-ion batteries. In reality, this additional charge interval will decrease the charging time without any loss in life, as batteries are more resistant to lithium plate failure at lower SOC.
In fact, the internal charging mechanism of a lithium-ion battery is closely tied to the chemical reactions of the battery. Consequently, the chemical reaction mechanisms, such as internal potential, the polarization of the battery, and the alteration of lithium-ion concentration, have a significant role in the charging process.
Subsequently, To determine the optimal pulse charge frequency in a lithium-ion battery, a variable frequency pulse charge system (VFPCS) strategy is proposed in . This method can identify the optimal pulse charge frequency and provide an optimal PC charging to the battery, decreasing the charging time.
