7.2.1 Battery use and distribution
General points
The electricity onboard is direct current.
The boat's electrical system comprises service batteries and the engine battery or batteries. The service batteries serve as the power supply for all the boat's electrical
components. The "engine" battery is used only for powering the electric starter of the propulsion engine.
The boat may also be equipped with:
- a generator powered by its own battery ;
- a bow thruster, powered by its own battery bank ;
- A stern thruster, powered by its own battery bank.
the batteries are charged either by a load distributor or:
- by the alternator linked to the engine when the engine is running,
- by the battery charger (if the boat has one).
It is imperative that when the boat is first launched, a professional engineer connects the batteries.
Always check the condition of the batteries and charge system before putting to sea.
The battery banks are isolated from one another by a charge divider (see below).
