The battery is now in a state of charge of >80%. Constant current (CC) charging requires the initial charge current to be limited to a % of the battery''s capacity to avoid unnecessary gassing. NOTE: Manufacturers publish different current limits for the BULK charge phase of a CC charge curve: 13% of the C20 (15%C5) rating for flooded deep-cycle

For a 12/30 battery charger: the reconditioning current is 30 x 0.08 = 2.4A. FLOAT. Float charging. Keeps the battery at a constant voltage and fully charged. STORAGE. Storage mode. Keeps the battery at a lower constant voltage to limit gas formation and corrosion of the positive plates. READY (battery fully charged)
Constant voltage (CV) allows the full current of the charger to flow into the battery until it reaches its pre-set voltage CV is the preferred way of charging a battery in laboratories.
CC charging is a simple method that uses a small constant current to charge the battery during the whole charging process. CC charging stops whena predefined value
The constant current charging method charges the battery with a steady current. Like the constant voltage method, when the battery is fully charged, the charger must switch to float
During the constant-current charge, the battery charges to about 70 percent in 5–8 hours; the remaining 30 percent is filled with the slower topping charge that lasts
Naturally, in real-life applications related to EV battery charging, the goal would be to recharge the battery up to 80–90% to avoid a constant-voltage operating regime

The constant current charging method charges the battery with a steady current. Like the constant voltage method, when the battery is fully charged, the charger must switch to float charging mode to prevent damage from overcharging. Compared to constant voltage charging, this method can fully charge the battery quickly.
Constant 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%.
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.
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.
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement. This method is suitable for Ni-MH type of batteries.
