Understanding The Battery Charging Modes: Constant Current and Constant Voltage Modes Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required.

Always, the battery cell charging is started with constant current mode and kept its CC mode till about 80% of the SOC . After that, the charger controls the output voltage at a constant value. The motivation for mode change is to charge battery cells in a safe range.
Constant Voltage Mode (CV Mode): In this mode, the charging voltage applied at the battery terminals is maintained constant regardless of the battery charging current. Let's examine these charging modes within the context of EV charging.
After the boost charging duration, the battery charger is to be put in float charging (trickle charge) mode for continuous operation. In this mode, the charger maintains the battery at its full charge level. Some chargers automatically switch to float charge mode after the charging current reduces below a certain value. Voltage and current values are recorded during the boost charging and float-charging mode.
Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required. To ensure the efficient and safe charging of batteries, it is crucial to understand the various charging modes.
