The inverters on the market generally use three-stage charging mode, which is followed by three stages of constant current charging, constant voltage charging and floating charging, commonly known as three-stage charging.
Three-stage charging principle
The three-stage charging process is as follows:
① In the constant current charging stage, the charging current of the charger remains constant, the charged amount increases rapidly, and the battery voltage rises;
In the constant voltage charging stage, the charging voltage of the charger remains constant, the charged electricity continues to increase, the battery voltage slowly rises, and the charging current drops;
③ The battery is full, the charging current drops below the floating charge conversion current, and the charging voltage of the charger decreases to the floating charge voltage;
④ In the floating charging stage, the charging voltage of the charger is maintained as the floating charging voltage;
For example:
12V9 battery pack
Floating charging voltage 1.125X12X9=121.5v
Uniform charging voltage 1.175 x 12X9=126.9v
