Battery charging system and method using dynamically adjusted battery voltage threshold for switching charging modes

A battery charging system for charging a battery, comprising:

• a charging circuit configured to charge the battery;
• and
• a controller communicatively coupled with the charging circuit,
• wherein the controller is configured to:
• determine a current condition of the battery, wherein the current condition comprises a current state-of-health (SoH) or a maximum state-of-charge (SoCmax) of the battery;
• dynamically determine a threshold voltage for controlling a charging mode of the charging circuit, based on the current condition;
• determine a battery voltage of the battery during charging;
• configure the charging circuit to charge the battery using a constant current (CC) mode when the battery voltage is less than the threshold voltage;
• and
• configure the charging circuit to charge the battery using a constant voltage (CV) mode when the battery voltage is equal to or greater than the threshold voltage.
