The charging process starts with an AC charger that sends Alternating Current to the ship and converts it to Direct Current to charge the battery. In many cases, the ship's existing AC-DC converter can be used, which is the most cost-effective solution.
Maintain fully charged lead acid battery on trickle charge as they suffer internal discharge. An automatic battery charger will detect the battery condition and automatically change over to trickle charge and complete charging. Check the state of charge of the batteries by measuring the terminal voltage while supplying load current.
In order to keep it in a fully charged position, it is practice to keep a small current just enough to balance the discharge. This small current is the trickle current. A charging circuit is designed to maintain this trickle current once full battery voltage has reached.
As it can be seen in the diagram, the batteries are in standby mode with the charging switches C closed and the load switches L open. The positions of these switches are held with the help of an electromagnetic coil against the spring tension. The electromagnetic coil gets its supply from the main power source available on the ship.
Vessel charging solutions are designed for ships that have an energy storage system – for example a marine battery. A marine charging system works in much the same way as a charging system for cars and other electric road vehicles. Vessel charging systems are not yet standardized like alternative marine power (AMP) systems.
This makes it possible for ferries to charge their battery during their short turnarounds. The cable handling system is the most visible part of the charging solution, but the electrical engineering happens between the grid and the cable handling system to convert the medium voltage grid into the power needed for the vessel.
