Three stage charging method for lead-acid battery

Aviation batteries are charged by stage constant current charging method.

General acid aviation batteries adopt constant current two-stage charging method.

Alkaline aviation battery adopts constant current two-stage charging method or constant current one-stage charging method.

However, this charging method is far from the charging current acceptance rate curve in the middle stage of charging, so the three-stage charging method is better.

The three-stage charging method is a combination of two-stage constant current charging method and constant constant voltage charging method.

Constant current is used at the beginning and end of charging, and constant voltage charging is used in the intermediate stage.

At the initial stage of charging, the battery is charged with a large current and changed to a constant voltage after a period of time. When the current attenuates to a predetermined value, it changes from the second stage to the third stage.

The advantages of the three-stage charging method are:

The constant voltage charging method avoids the situation that the charging current is too large at the beginning and too small at the later stage, which is closer to the charging current acceptance rate curve in the middle stage than the two-stage equal current charging.

This charging method reduces the charging air output, charges thoroughly, and prolongs the service life of the battery.
