Design and development of battery monitor for e-bikes Executive Summary: In electric vehicles power battery management system is the most important task, which is necessarily carried out to prevent the battery over-charging and over-discharging. Lithium ion batteries is the most used battery component and the battery that promotes high capacity, safety and long life is the lithium iron phosphate (LiFePO4) and the charging method mostly adapted is the current charge- constant voltage method (CC-CV). This method deals
