Basically, ignore the fact that it is pulsing. Each pulse must have its voltage and/or current limited in the same way for a continuous charge. So the simplest way of charging a lead acid battery is to limit the charging voltage to approximately 13.8v for a 12v battery, although this may vary depending on the manufacturer, temperature etc.
Effect of Pulse Charging in Lead acid Batteries Used in Electric Vehicles of Nepal The major factor in reducing the life of the lead acid battery is sulfation. Sulfation forms a layer of Lead Sulphate crystal in the electrodes making it less conductive or even blocking the electrical current to pass through it.
The method of the research is experimental in which different patterns and relations found between the parameters of the battery are analyzed. The basic tests performed included the pulse charging of flooded and VRLA type lead acid batteries in various frequencies with the maximum of 2.5 MHz.
Proper monitoring during charging is crucial for safety and performance. Lead-acid batteries produce hydrogen and oxygen gases as they charge, particularly in the later stages of charging. These gases can accumulate and become hazardous if not properly ventilated.
Different frequencies reflect different lead-acid battery parameters, from ohmic resistance (high frequency) through charge transfer resistance at the electrodes and diffusion double layer capacitance (moderate frequency) to Warburg impedance associated with ion diffusion in the electrolyte and electrode pores (low frequency).
Temperature Control: Ideally, lead-acid batteries should be charged at temperatures below 80°F (27°C). Charging at high temperatures can lead to thermal runaway, where the battery overheats and becomes damaged. If your battery becomes hot to the touch during charging, stop the process immediately and allow it to cool. 4. Avoiding Overcharging
