4. Equalize drifting battery cells
Individual battery cells may increasingly vary
in charge resistance over time. An uneven
acceptance of charge can lead to significant
capacity deterioration in weaker cells. Equalization
is a process to overcome such unbalanced cells.
The increased charge acceptance and capacity
recovery capabilities of PWM pulse charging
will also occur at lower charging voltages.
Morningstar’s PWM pulse charging will hold
the individual battery cells in better balance
where equalization charges are not practical
in a solar system.
More testing will be done to study the potential
benefits is this area.
