6 FAQs about [Reasons for constant voltage charging of lead-acid batteries]

How to charge a lead acid battery?

The lead-acid battery mainly uses two types of charging methods namely the constant voltage charging and constant current charging. It is the most common method of charging the lead acid battery. It reduces the charging time and increases the capacity up to 20%. But this method reduces the efficiency by approximately 10%.

Why is charging current important for lead acid batteries?

The higher the charging current, the higher is the capacity restituted. In the same way, energy efficiencies increased with increase in charging current. This then suggests that the choice of charging current is of paramount importance as the charging efficiency of lead acid batteries is concerned.

Why is battery charging at constant voltage a good idea?

The charging current is high in the beginning when the battery is in the discharge condition. The current is gradually dropping off as the battery picks up charge resulting in increase back emf. The advantages of charging at constant voltage are that it allows cells with different capacities and at the different degree of discharge to be charges.

How a battery is charged at a constant voltage?

In this method the charging current is high in the beginning when a battery is in discharged condition, and it gradually drops off as the battery picks up charge resulting in increased back emf. Charging at constant voltage may be carried out only when the batteries have the same voltage, for example, 6 or 12 or 24 V.

How long does a lead-acid battery take to charge?

The lead-acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries.

What happens if a battery has a large charging current?

The large charging current at the beginning of the charge is of relatively short duration and will not harm the cells. At the end of the charge the charging current drops to almost zero because the voltage of the battery becomes nearly equal to the voltage of the supply circuit.
