A schematic diagram of the solar battery charging circuit. The battery is charged when the voltage of the solar panel is greater than the voltage of the battery. The charging current will decrease as the battery gets closer to being fully charged. This is just a simple circuit, and there are many other ways to charge a battery from solar power.
This integrated system can utilize solar energy and control the charging of battery at maximum efficiency, so that the Li-ion battery can be fully charged within a short time. This system is thus proven to be feasible. Moreover, this study used the simplest CV to minimize the cost.
Constant Voltage Charging: This strategy involves maintaining a constant voltage across the battery terminals during the charging process. This is a simple and effective approach, but it can result in overcharging if the voltage is set too high .
The choice of charging strategy will depend on the specific requirements and limitations of the off-grid solar PV system . Factors such as battery chemistry, capacity, load profile, and environmental conditions will all influence the optimal charging strategy .
The specifications of the solar cell used are 100 WP, while the charging process uses a DC-DC Sepic Converter. DC-DC Sepic Converter can increase efficiency and output polarity that is not reversed. This system is used to charge the lead-acid battery of 12 Volt 20 Ah.
Effective battery charging strategies are essential to ensure optimal battery performance and longevity in off-grid solar PV systems. There are several battery charging strategies available, such as constant voltage, constant current, pulse charging, and float charging.
