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.
