Battery monitoring system by detecting dead battery cells

Abstract

The development of battery monitoring system by detecting dead battery cell is proposed in this paper. The experiment of charging and discharging process is tested in different values of the current in order to compare the experimental parameter at different condition. During the process, the parameters of battery, which are current, voltage, and temperature are send to display on the computer and analyzed in order to detect the dead battery cell. The monitoring device also shows the parameter of battery during testing. CAN (Controlled Area Network Communication) is used to transfer all data between the microcontroller and the proposed PLC together with a computer. The outputs showing on the displaying screen are voltage per cell, current of charging or discharging, temperature within battery, power density, and also energy density. The dead battery cells and efficiency of battery can also be indicated by this monitor device.
