A battery charging strategy in photovoltaic systems using fuzzy logic control

الملخص EN

Battery charging control is the most important part in Stand-Alone PV system, because
it is responsible for the performance of the system.

There are two types of charger
controllers, the first is the pulse width modulation (PWM) and the second is the
maximum power point tracking (MPPT).

This paper introduces a charging strategy that
improves the efficiency of battery charging process and enhances the battery life by using
the PWM technique.

An experimental proposed fuzzy logic module is embedded in a
microcontroller.

The measured response showed smooth charging especially during
critical phase of battery charging and preventing the battery bank from any overcharging
, undercharging and sulfation.
