12V 20A lithium battery charger

1. Pre-charge stage (T0):

In this initial step, the battery is prepared to the correct voltage. The LED light glows white, indicating that there is no AC input.

2. Constant current charging stage (T1): In this phase, the battery is charged with a constant current. During this process, the light glows red to indicate that the battery is being charged. The voltage increases during charging.

3. Constant voltage charging stage (T2): Here, the voltage is kept constant until the battery is full. The LED light turns green, which means the battery is fully charged or there is no connection.

In summary, the charging process demonstrates a safe and efficient method for charging lithium batteries, ensuring a smooth transition between the phases.
