ABSTRACT:
This paper presents Mathematical Model and Experiment of Temperature
effect on Charge and Discharge of Lead-Acid Battery performance in PV system
power supply. To test temperature effect on battery discharge cycles, a
temperature range of tropical area from 25 - 60
degrees Celsius in a simulator is set up for testing. This temperature range is
normally practical for battery usage. This allows the battery to determine the
parameters of the battery quickly and high accurate. A Mathematical Model with
MATLAB Program is written and constructed as block diagram using the equations
of battery the parameters. By running program, the effects of various
parameters are investigated. The results showed that time of discharge the
battery is longer. Then, the experiment is set up by battery VRLA 12 V 20 AH. The
results confirmed the mathematical model simulations.
