Charging Modes

The Kings 25A DC-DC charger employs a multi-stage charging process to optimize battery life and performance. It offers two primary charging modes⁚ Bulk Charging and Float Charging, which are automatically adjusted based on the battery’s state of charge and type.

• Bulk Charging⁚ This is the initial stage where the charger delivers a high current to quickly bring the battery up to approximately 80% of its full capacity. The charger monitors the battery voltage and adjusts the current accordingly to prevent overcharging.
• Float Charging⁚ Once the battery reaches approximately 80% charge, the charger enters the float charging mode. This stage maintains a constant voltage to keep the battery fully charged without overcharging. The float charging mode ensures that the battery remains at optimal charge levels and prevents sulfation, which can reduce battery life.

In addition to these primary modes, the charger also features an MPPT (Maximum Power Point Tracking) algorithm when connected to a solar panel. This algorithm optimizes the charging process from solar energy by constantly adjusting the charging current to maximize the power output from the solar panel, even under varying sunlight conditions. The MPPT functionality ensures efficient utilization of solar energy, maximizing the battery’s charge from solar power.

The Kings 25A DC-DC charger also offers a Battery Type Selection feature, allowing you to choose the appropriate charging profile for different battery chemistries, such as lithium, AGM, and lead-acid.
