A wireless power transfer (WPT) platform optimization design for a contact less charging system is proposed. Drawbacks of WPT include low power transfer, low operation efficiency, and unstable output voltage, which are caused by various air gaps between the coils. A shuffled frog-leaping algorithm (SFLA) is hence applied to obtain the optimal frequency, meanwhile anticipating reaching the maximum...
This paper proposes a charging control strategy for lithium-ion batteries. The method applies the post-charged steady-state battery voltage to justify the characteristics of durability for the lithium-ion battery, while the possibility of over-charging and under-charging conditions can be better avoided. In the method, the charging capacity, the charging security, and battery durability are all taken...
