In most cases, batteries are used to store the energy generated by photovoltaics(PV), in order to be used later when the sun sets or on cloudy days, especially in remote areas that are not connected to the electrical grid. Although some loads can operate on a non-constant voltage, such as water pumps or fans, etc., other.

Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries. With higher charge current s and multi-stage charge methods, the charge time can be reduced to 10 hours or less; however, the topping charge may not be complete.

Conferences > 2016 3rd International Confer... Charging method is crucial for any batteries. Over the years, many charging algorithm are developed to improve the charging method of lead acid battery. Uncontrolled charging of lead acid battery may lead to capacity loss and also reduce the life cycle of battery.
