Constant current charging is when the charger supplies a set amount of current to the battery, regardless of the voltage. This stage is used to overcome any internal resistance in the battery so that it can be charged as quickly as possible. After the initial constant current stage, the charger then switches to a constant voltage mode.
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.
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.
Pre-charging is when the battery is initially plugged in and is drawing a very small amount of current in order to get the chemical reaction started within the battery. Constant current charging is when the majority of the charge is applied to the battery.
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.
