Battery Charger E148 for solar or wind power The lifetime and capacity of a battery used in secondary power supply systems for marine aids to navigation strongly depends on the operating conditions and on the charging process. This is particularly important when using solar and wind energy due to irregularity of supply. For instance, the amount of available solar energy during the winter months is very small and solar powered systems may need to operate using the energy accumulated in summertime. Therefore, the charging system has to maintain the batteries as fully charged as possible while not overcharging them. Overcharging would lead to boiling out of the electrolyte and resultingly, to damage to the batteries.
Cybernetica AS has applied special efforts to find the most efficient methods of charging the batteries and, as a result, the microprocessor controlled optimizing battery charger E148 has been developed. The purpose of this
charger is to guarantee the continuous power supply of autonomous systems using solar and/or wind/wave energy for charging the lead or gel batteries. When optimizing the charging procedure the type, nominal voltage, capacity, and the charge
factor of the battery as well as the temperature of the ambient air are taken into consideration. The optimization will be performed using an algorithm in the firmware of the microprocessor. The Solar Charger E148 is ready to be integrated into a remote control and monitoring system for utilization of its diagnostics capabilities. |
