A Study on Li-Ion Power Battery Formation Energy Recycling Technology

Article Preview

Abstract:

Li-ion power battery which has a broad prospect of application in many industry fields is a new type of high power battery. The formation is a necessary process in battery manufacture. Every battery should be charged and discharged several times. On account of the current li-ion power battery’s problem of great amount of energy waste for using conventional techniques in the process of formation, two schemes about formation energy recycling are proposed. One of the schemes is to transfer energy from discharging batteries to charging batteries. It uses energy balance control strategy, and the efficiency can reach to 98%. The other one which uses PWM rectifier is energy feedback to grid scheme. The efficiency can reach to 95%.
