The supply of own services of direct current is made from at least two sources of DC power, the independent and capable sources of ensuring, each of them, the entire consumption. As a normal power source, are used AC/DC rectifiers and DC/DC converters, as the case. The provision of safety power supplies its able to take over, for a limited time, normalized, the whole consumption in the DC of this objective, is mandatory for all objectives. As a safe power supply are used battery packs. Each battery pack supplies a single network; it is not supplied from the same battery, two or more distribution networks, with different nominal voltages through intermediate sockets. For voltage supply, in case of dismissal of the basic source, they can be used as local sources, which provide electricity directly, the battery, built to ensure the required voltage and capacity in battery packs. The ships present the damaged installation which can operate supplied by battery packs. Electrical control circuits, signalization circuits, protection circuits and automation circuits are supplied with DC voltage. In this article we will calculate the battery capacity of a ship.
