Lithium-ion batteries explained
A Li-ion battery (a set of Li-ion cells in series) is charged in three stages: Constant Current, Balance (not required once a battery is balanced) and Constant Voltage. During the constant current phase, the charger applies a constant current to the battery at a steadily increasing voltage, until the voltage limit per cell is reached.
Constant Voltage, Constant Current Battery Charging
May 26, 2016 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 current will then …
