Free QuoteConstant current charging is a method of continuously charging a rechargeable battery at a constant current to prevent overcurrent charge conditions. Constant voltage charging is a method of charging at a constant voltage to prevent overcharging. The charging current is initially high then gradually decreases.
During the constant voltage mode, the charging current starts to decrease. When the charging current drops to a predefined minimum current value (e.g., 0.05 C), the charging process concludes, indicating the battery is fully charged (e.g., battery state of charge is 100%).
The constant voltage method of charging batteries is one of the most common and simplest methods. It involves applying a constant voltage to the battery, typically around 14.4V for lead acid batteries, until the current flowing into the battery drops to a very low level. At this point, the battery is considered fully charged.
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.
Since the voltage is constant, the charging current decreases as the battery charges. A high current value is required to provide a constant terminal voltage at anearly stage of the charging process.
The charging switches to constant voltage (4.2 V) when the battery's internal voltage exceeds or equals 4.2 V. The process concludes when the charging current drops below 0.05 C. Figure 13 and Figure 14 illustrate the charging profile and flowchart of the Type III CC-CV charging method.
