The ‘Four-stage adaptive with BatterySafe mode’ is a sophisticated charging algorithm designed specifically for optimizing the charging process of lead-acid batteries.
This algorithm operates in four distinct stages: bulk, absorption, float, and storage, each tailored to the battery’s needs at various charge levels.
Here’s a brief rundown of each stage:
-
Bulk: This is the first stage where the charger delivers maximum current to the battery until it reaches the absorption voltage.
-
Absorption: Once the bulk voltage is reached, the charger switches to absorption mode, maintaining the voltage and allowing the current to taper down. This ensures the battery is brought up to a full charge without overcharging.
-
Float: After the absorption stage, the charger reduces the voltage to a maintenance level to keep the battery at 100% charge without incurring damage that can result from overcharging.
-
Storage: If the battery is not being used, the charger enters storage mode, reducing the float voltage further to minimize gassing and corrosion of the battery plates.
The BatterySafe mode part of the algorithm helps prevent battery damage due to excessive gassing by limiting the voltage increase rate once gassing voltage has been reached.
This adaptive charging method is recommended for lead-acid batteries because it accounts for their specific charging needs, prolonging battery life and maintaining efficiency.
For other types of batteries, like lithium-ion, the charging parameters can be adjusted using the software provided by Victron Energy, ensuring that each battery type gets the right charging profile.
Always refer to the help files in the software configuration programs for detailed instructions on setting this up correctly.
