Lead acid battery charging schematic
Lead Acid Battery. Definition: The battery which uses sponge lead and lead peroxide for the conversion of the chemical energy into electrical power, such type of battery is called a lead acid battery. The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost.The circuit shown in Figure 1 charges leadacid batteries in the conventional way: A currentlimited power supply maintains a constant voltage across the battery (approximately 2. 4Vcell, as specified by the battery manufacturer) until the charging current decreases below a current threshold defined by the capacity of the battery. lead acid battery charging schematic
The circuit diagram of 12V lead acid battery charger is shown in figure 1. This circuit is built around fixed voltage regulator, variable voltage regulator, dual operational amplifier IC, Transistor, Relay, Transformer and few other electronic components.
