Lead acid batteries can be divided into two distinct categories: flooded and sealed/valve regulated (SLA or VRLA). The two types are identical in their internal chemistry (shown in Figure 3). The most significant differences between the two types are the system level design considerations.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
Lead acid batteries have been around for more than a century. In the fully charged state, a 2V electric potential exists between the cathode and the anode.
However, due to the corrosive nature the elecrolyte, all batteries to some extent introduce an additional maintenance component into a PV system. Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%.
The performance and life cycle of Sealed Lead Acid (SLA) batteries for Advanced Metering Infrastructure (AMI) application is considered in this paper. Cyclic test and thermal accelerated aging test is performed to analyze the aging mechanism resulting in gradual loss of performance and finally to battery's end of service life.
The production and escape of hydrogen and oxygen gas from a battery cause water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs.
During discharge, electrons are passed externally through the load while internal chemical reactions at the interface of the electrolyte and the electrodes work to balance the charge equilibrium. Figure 3 illustrates the chemical states of a fully charged and discharged lead acid battery.
Lead acid batteries can be divided into two distinct categories: flooded and sealed/valve regulated (SLA or VRLA). The two types are identical in their internal chemistry (shown in Figure 3). The most significant differences between the two types are the system level design considerations.
