Battery Management Systems for Electric Vehicles using Lithium Ion Batteries

Abstract

Electric Vehicle technology plays an important role in greenhouse gas limitation and carbon pollutions. Rechargeable batteries are used to deliver power to the auxiliary systems and motor in the electric vehicle applications. Various classifications of rechargeable batteries are available nowadays, for electric vehicle applications. Among all rechargeable batteries, Lithium Ion Batteries will give high efficiency for electric mobility because Li-Ion batteries have low self-discharge rate, wide operating range, maximum energy density and high life cycle. To improve the quality of battery and safe operation, battery management system is employed and it plays a vital role in application of Electric Mobility. This paper reviews the attributes of battery management system and its technology with advantages and disadvantages for electric vehicle application. This review includes the battery cell monitoring, state estimation, charging and discharging control, temperature control, fault analysis, data acquisition and protection schemes to improve the performance of battery for EV applications.
