Battery Equalization
Equalization function is added into charge controller. It reverses the buildup of negative chemical effects like
stratification, a condition where acid concentration is greater at the bottom of the battery than at the top.
Equalization also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this
condition, called sulfation, will reduce the overall capacity of the battery. Therefore, it’s recommended to
equalize battery periodically.
- How to Apply Equalization Function
You must enable battery equalization function in monitoring LCD setting program 33 first. Then, you may apply
this function in device by either one of following methods:
1. Setting equalization interval in program 37.
2. Active equalization immediately in program 39.
- When to Equalize
In float stage, when the setting equalization interval (battery equalization cycle) is arrived, or equalization is
active immediately, the controller will start to enter Equalize stage.
- 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.
31
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.
