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.
