  • Electrical system, part 3 – Battery selection in the subsystems

    In this article, I write about a few different things that affect the type of battery and how much battery capacity may be needed for various purposes on board. Here you can find information about the typical consumption of electric energy, how much electricity production is needed, and a justification for the battery choice in…

  • Elsystem, del 3 – Batterival i delsystemen

    I den här artikeln skriver jag om några olika saker som påverkar vilken typ av batteri och hur stor batterikapacitet som kan behövas för olika ändamål ombord. Här finns information om typisk elförbrukning, hur mycket elproduktion som behövs samt en motivering av batterivalet i de olika delsystemen i den fiktiva segelbåt som artiklarna använder som…

  • Electrical system, part 3 – Connect the battery bank

    Often you need more capacity than what is in a battery and this is solved by connecting several batteries in parallel. If the subsystem needs a higher voltage than a battery has, it is solved by connecting batteries in series. In this article, you will learn how to connect the battery bank.

  • Elsystem, del 3 – Koppla Batteribanken

    Ofta behöver man mer kapacitet än vad som finns i ett batteri och det löser man genom att parallellkoppla flera batterier. Behöver delsystemet högre spänning än vad ett batteri har, löser man det genom seriekoppling av batterier. I den här artikeln lär du dig hur batteribanken kopplas ihop.

  • Electrical system, part 3 – Battery chargers

    There are several different chargers on board that are used to charge batteries from different energy sources such as the alternator on the main engine, shore power, solar panels, wind turbines, hydro generator, or generator. It is easy to get complicated electrical installations with different chargers that must work together to charge the important and…
