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.
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.
To address this issue, a multi-stage voltage charging method can be employed. This approach uses a lower charging voltage initially, then increases it as the battery terminal voltage rises. The constant current charging method charges the battery with a steady current.
When I begin charging lead acid batteries, I typically follow a three-phase method. Firstly, during the Initial Charge Phase, I supply constant current which facilitates around 80% of the recharge, where the voltage gradually rises.
Charging voltage = OCV + (R I x Battery charging current limit) Here, R I is considered as 0.2 Ohm. Observing the below picture, it becomes evident that the DC power source regulates its charging voltage in accordance with the charging current limit.
The MCC method is suitable for charging the following battery types: lead-acid, NiMH, and Li-ion batteries. With equal initial current values, the MCC charging process takes a bit more time compared to the CC-CV charging method.
