In this chapter the solar photovoltaic system designer can obtain a brief summary of the electrochemical reactions in an operating lead-acid battery, various construction types, operating characteristics, design and operating procedures controlling 1ife of the battery, and maintenance and safety procedures.
Several existing techniques for predicting the remaining capacity of a lead-acid battery discharged with a variable current are based on variants of Peukert's empirical equation, which relates the available capacity to a constant discharge current.
The capacity of a lead–acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert's law.
Lead–acid batteries typically have coulombic (Ah) efficiencies of around 85% and energy (Wh) efficiencies of around 70% over most of the SoC range, as determined by the details of design and the duty cycle to which they are exposed. The lower the charge and discharge rates, the higher is the efficiency.
Implementation of battery man-agement systems, a key component of every LIB system, could improve lead–acid battery operation, efficiency, and cycle life. Perhaps the best prospect for the unuti-lized potential of lead–acid batteries is elec-tric grid storage, for which the future market is estimated to be on the order of trillions of dollars.
