Design and estimation of state charging applied for lithium ion battery based on Matlab Simulink
For green technology applications, the lithium ion battery is widely adopted as energy storage system due to high power and high energy density. However, there is a drawback on the storage system on charging interval time, particularly on electric vehicle applications. To accelerate, the multi state current technique becomes a solution. In this paper, the state charging of the lithium ion battery modeled by Matlab/Simulink is discussed. The state of charge (SOC) is measured and applied to evaluate the battery's charge/discharge characteristic. The multiple charging states applied for filling the battery capacity are evaluated in order to achieve high efficiency. In addition, the configurable three state current design manipulated by a 8 bit microcontroller is introduced with a constant voltage at 20V and variable current from 5A to 60A. The investigation results are illustrated that, operating on Lithium ion Ferro battery 12V 30Ah, the interval time of fill up is reduced approximately 30% with working temperature 35deg C.
