In conclusion, constant current battery chargers are essential for ensuring the longevity and functionality of batteries, especially in devices that require consistent power. These circuits come in different configurations and designs, each with unique features and advantages that meet specific charging needs.
For charging the battery in CC and CV mode separate constant current and constant voltage source need to be designed. Both constant current and constant voltage sources can be designed using LM317 voltage regulator IC.
This circuit will provide different voltage output according to the input voltage and constant current output depends on the value of Reference Resistor R1. Circuit Diagram Construction & Working To construct constant current DC power supply circuit first we need to build Rectifier circuit by implementing step down transformer and Bridge Rectifier.
In Constant Voltage state, the same voltage is applied at a constant rate by the charger circuit at the terminals of the battery. Trying to charge the battery by applying a higher voltage than this may charge the battery fast but it reduces the battery life.
An adjustable voltage/current supply is an interesting tool, which can be used in many applications such as a Lithium-ion/Lead-acid/NiCD-NiMH battery charger or a standalone power supply. In this article, we will learn to build a variable step-down buck converter using the popular LM2576-Adj chip.
In CC mode the charging current must be 500 mA but the charging voltage has to be determined for this mode. This voltage can be determined by the charging curve of the battery shown below. Fig. 5: Graph showing Charging Curve of Li-ion Battery It can be observed that in CC mode the battery charging voltage is equivalent to the battery real voltage.
