When charging processes are completed, the battery packs stand for another 2 h to reach thermal balance again, after which discharging process starts according to GB/T 18332 (lead-acid batteries used for electric road vehicles, referred to IEC 61982–1:2006, secondary batteries for the propulsion of electric road vehicles − Part 1: Test parameters, MOD).
Abstract. The traditional methods of charging lead-acid batteries depend on stabilizing the current or voltage through simple electronic circuits, which causes the shorten the life of the batteries due to damage to the electrodes or the hot and dry batteries.
There are many types of lead-acid batteries and they can be classified in several forms and several ways, and for the sake of knowing them clearly, they can be classified first into two main sections, open or closed sealed. Both types are made from plates. These plates are divided into two types, flat and tubular plates.
Lead-acid batteries of all kinds are relatively cheap and can be produced in large quantities with high power and capacity , so they are preferred over other types of batteries, especially in photovoltaic systems.
Electrochemical battery models (Doyle, Fuller, and Newman, 1993; Haran, Popov, and White, 1998) are based on partial differential equations accounting for the dynamics of particles inside the battery. Albeit highly accurate, these models are quite complex and require knowledge of a large number of parameters which are difficult to obtain.
The electrolyte contains aqueous ions (H+ and SO4 -2). The conduction mechanism within the electrolyte is via migration of ions via drift & diffusion. Lead atom becomes ionized and forms ionic bond with sulfate ion. Two electrons are released into lead electrode
Today, due to their low cost, ease of manufacture, durability, low self-discharge, and not need maintenance, especially gel type. lead-acid batteries are widely used in photovoltaic systems. We will cover this type of cell in this chapter [3, 4, 7, 8].

Positive electrode of lead-acid battery is ( PbO_{2} ), which are typically brown and granular, have better access to the electrolyte, increasing the reaction area and reducing the battery''s internal resistance.Battery negative pole is ( Pb ), dark gray spongy; Electrolyte is a dilute sulfuric acid solution mixed by concentrated sulfuric acid and distilled water in a certain …
If current is being provided to the battery faster than lead sulfate can be converted, then gassing begins before all the lead sulfate is converted, that is, before the battery is fully charged. Gassing introduces several problems into a lead acid battery. Not only does the gassing of the battery raise safety concerns, due to the explosive nature of the hydrogen produced, but gassing also ...
In practice, the relationship between battery capacity and discharge current is not linear, and less energy is recovered at faster discharge rates. Near end of charge cycle, electrolysis of water reduces coulomb efficiency. Can improve this efficiency by reducing charge rate (taper charging)

charge parameters are easily modified to work with dif-ferent lead-acid batteries. The typical method of charging lead-acid batteries is with a constant voltage, current-limited source. That method allows a high initial charge current that tapers off until the battery reaches full charge. This design uses a constant current, allowing the volt-

One of the most critical parameters of performance in lead-acid batteries, especially those for automobile purposes, is Cold Cranking Amps (CCA).

This occurs since, particularly for lead acid batteries, extracting the full battery capacity from the battery dramatically reduced battery lifetime. The depth of discharge (DOD) is the fraction of battery capacity that can be used from the battery and will be specified by the manufacturer. For example, a battery 500 Ah with a DOD of 20% can only provide 500Ah x .2 = 100 Ah.

In practice, the relationship between battery capacity and discharge current is not linear, and less energy is recovered at faster discharge rates. During discharge, ohmic losses in electrolyte and contacts lower voltage. Internal impedance increases due to lowering electrolyte concentration and electrode sulfation.
