Electrolysis inhibiting marine energy management system

摘要

Supply of ac current from the marina source to the boat's DC loads is permitted only when an isolation relay completes the electrical circuit therebetween. A control means monitor the boats battery voltage, battery charger current and DC load current, and supplies operating current to the isolation relay only when those monitored conditions indicate a need for the supply of current from the on-shore source to the boat. The duration in which the on-shore ground lead is connected to the boat's ground system, a customary path for electrolysis currents, and corrosion damage caused by those currents, and the duration of consumption of on-shore electricity, are thus limited.
