[...] The purpose of the presented flyback converter is to equalise the voltage between the cells in a series string within a battery pack providing an active cell-balancing system.
Constant current discharge is the discharge of the same discharge current, but the battery voltage continues to drop, so the power continues to drop. Figure 5 is the voltage and current curve of the constant current discharge of lithium-ion batteries.
By Irena Zhuravchak and Volodymyr Ilchuk | Tuesday, June 27, 2023 Charging a battery using the constant-current/constant-voltage (CC/CV) method involves using the constant current in the initial state of charging and then switching to constant voltage in the later stages of charging, when the battery reaches the set charge level.
