AI Customer ServiceConstant current (CC) charging initially allows the full current of the charger during the BULK stage to flow into the battery regardless of the battery state of charge or the temperature until the battery terminal voltage reaches a pre-set steady state. The battery is now in a state of charge of >80%.
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.
There are three common methods of charging a battery: constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit. Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage.
Characteristics of Constant Voltage Source: Fixed Output Voltage: The primary feature of a CV source is its ability to supply a consistent voltage output regardless of the load current. Varying Current: The output current changes depending on the load.
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Constant current/constant voltage is a combination of the above two methods. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level.
Understanding Constant Current and Constant Voltage Sources Constant current (CC) sources and constant voltage (CV) sources are the two types of power sources to take into account while working with electronics. These terms describe how a power source supplies energy to a load, but they serve distinct purposes in different applications.
