The maximum power of the photovoltaic panel is tracked by the Perturb and Observe MPPT algorithm. The battery charge controller charges the lead-acid battery using a three-stage charging strategy. The three charging stages include the MPPT bulk charge, constant voltage absorption charge, and float charge stage.
Bulk, Absorption, and Float are the 3 main charging stages of a typical lead acid battery. In addition, there could be one more stage called equalizing charge. Bulk Charging Stage So, the first charging stage is bulk, in which the battery is typically less than 80% charged.
Over time layers form in the electrolyte which means that the acid becomes concentrated at the bottom of the battery. Otherwise called ‘stratification’, this can cause damage to the bottom area of the battery plates. An equalizing charge is meant to help reverse the stratification effect. Also, sulfate crystals accumulate around the plates.
An equalizing charge is the addition of an extended charge at the end of the normal charging process. When this is done, the extended charge removes the sulfate coating around the battery plates allowing all the surface area of the plates to interact fully with the electrolyte in the battery.
Therefore, one of the alternatives to store energy is batteries. As a result, the solar photovoltaic charge controller plays a very important role in allowing this solution to be possible. The MPP charge controller for solar photovoltaics is made up of a BCC and an MPP tracker.
In the realm of battery maintenance, equalizing charge is a crucial procedure, particularly for flooded lead-acid batteries. This specific maintenance technique ensures optimal performance and extends the lifespan of batteries by addressing common issues such as sulfation and voltage imbalances.
