The three stages of battery charging are known as the bulk stage, the absorption stage, and the float stage. Each stage has a different purpose and helps to keep your battery working at its best. During the bulk stage, the charger supplies a high current to the battery in order to quickly charge it up.
The first stage of battery charging is called the constant current stage. In this stage, the charger supplies a constant amount of current to the battery. The purpose of this stage is to quickly bring the battery up to an acceptable voltage level. Once the battery reaches this level, it will move on to the next stage of charging.
When the battery cell voltage reaches 3.0 V, the charger will increase the constant current and gradually increase the voltage, which is the main stage of lithium battery charging. Definition: Replaces ≈80% of the battery's state of charge at the fastest possible rate. This is a constant-current stage.
The second stage of battery charging is called the constant voltage stage. In this stage, the charger supplies a constant voltage to the battery. The purpose of this stage is to slowly top off the battery so it doesn't overcharge and become damaged.
Battery charging is a process that involves multiple stages in order to ensure the longevity and safety of your battery. Although the number of stages can vary depending on the type of battery, most batteries will go through four distinct phases when being charged.
The third stage is called constant voltage or CV for short. In this stage, the voltage of the battery is held at a constant level while the current gradually decreases. This ensures that your battery receives a full charge without being overcharged which can shorten its lifespan significantly.
