Equalize charging time and timeout
In Equalize stage, the controller will supply power to charge battery as much as possible until battery voltage
raises to battery equalization voltage. Then, constant-voltage regulation is applied to maintain battery voltage
at the battery equalization voltage. The battery will remain in the Equalize stage until setting battery equalized
time is arrived.
However, in Equalize stage, when battery equalized time is expired and battery voltage doesn’t rise to battery
equalization voltage point, the charge controller will extend the battery equalized time until battery voltage
achieves battery equalization voltage. If battery voltage is still lower than battery equalization voltage when
battery equalized timeout setting is over, the charge controller will stop equalization and return to float stage.
