How many stages are there in lithium batteries?
Lithium batteries usually divided into 3 stages: Constant Current Pre-charge, Constant Current Regulation Mode (CC), Constant Voltage Regulation Mode (CV).
What are the three phases of a battery charger?
The three phases are: I-phase (constant electric current), Uo-phase (constant over- voltage), and U-phase (constant voltage). The purpose is to fully charge the battery in a relatively short time without reducing its life span and to keep the battery charged indefinitely as long as the charger is connected.
What is Stage 3 of a battery?
Stage 3 is called the U-phase or float charge state, the voltage is reduced to a value that is safe to be applied for long periods (weeks) without significantly reducing the lifetime of the battery. During this phase, the charge current decreases gradually to a small residual value that compensates for any self-discharge of the battery.
