Discussions The charging and discharging of lead acid batteries permits the storing and removal of energy from the device, the way this energy is stored or removed plays a vital part in the efficiency of the process in connection with the age of the device.
In this paper, the impact of high constant charging current rates on the charge/discharge efficiency in lead acid batteries was investigated upon, extending the range of the current regimes tested from the range [0.5A, 5A] to the range [1A, 8A].
Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
Given the fact that for lead acid batteries, the electrodes are dipped inside the electrolyte, a change in the temperature of the electrolyte will easily be noticed on the negative plate since the anode is made up of metallic lead which is a good conductor of thermal energy.
The larger the electric charging currents, the greater the effective energy stored. Larger charging current rates provoke higher temperature increases in older than newer batteries. The charging and discharging of lead acid batteries using Traditional Charge Controllers (TCC) take place at constantly changing current rates.
Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles. Batteries with tubular plates offer long deep cycle lives.
