What Is Depth of Discharge (DOD)? <\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t

Die Austragstiefe (DOD) beschreibt wie viel der gespeicherten Energie einer Batterie verbraucht wurde<\/strong>.
Beispiel\uff1a<\/p>

  • Wenn eine 10 kWh-Batterie 5 kWh verbraucht \u2192 DOD = 50%<\/p><\/li>

  • Wenn es 9 kWh verbraucht \u2192 DOD = 90%<\/p><\/li><\/ul>

    Je h\u00f6her der DOD-Wert, desto st\u00e4rker ist die Batterie entladen.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    \n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t\t\t\t\t\"\"\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Warum DOD f\u00fcr die Batterielebensdauer wichtig ist<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t
    \n\t\t\t\t\t\t\t

    Die Lebensdauer einer Batterie ist eng mit dem DOD verbunden.<\/p>

    • Geringerer DOD = l\u00e4ngere Lebensdauer<\/strong><\/p><\/li>

    • H\u00f6here DOD = st\u00e4rkere Belastung der Batterien<\/strong><\/p><\/li><\/ul>

      Zum Beispiel:<\/p>

      • Blei-S\u00e4ure-Batterien\uff1aempfohlen DOD 30-50%<\/p><\/li>

      • Lithium (LiFePO4) Batterien\uff1ak\u00f6nnen sicher 80-95% DOD erreichen<\/p><\/li><\/ul>

        Aus diesem Grund halten Lithiumbatterien viel l\u00e4nger als Blei-S\u00e4ure-Batterien.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

        \n\t\t\t\t
        \n\t\t\t

        Wie DOD die Lebensdauer des Zyklus beeinflusst<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
        \n\t\t\t\t
        \n\t\t\t\t\t\t\t

        Die Zyklenlebensdauer gibt an, wie oft die Batterie vollst\u00e4ndig geladen und entladen werden kann.<\/p>

        Akku-Typ<\/th>Empfohlenes DOD<\/th>Zyklus Leben<\/th><\/tr><\/thead>
        Blei-S\u00e4ure<\/td>30-50%<\/td>300-600 Zyklen<\/td><\/tr>
        NCM Lithium<\/td>70-80%<\/td>800-1.500 Zyklen<\/td><\/tr>
        LiFePO4<\/td>80-95%<\/td>3.000-6.000+ Zyklen<\/td><\/tr><\/tbody><\/table><\/div><\/div>

        LiFePO4-Batterien sind f\u00fcr Solarsysteme sehr beliebt, da sie auch bei hohem DOD eine lange Lebensdauer haben.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

        \n\t\t\t\t\t\t\t

        • 100% SOC = 0% DOD<\/strong><\/p><\/li>

        • 20% SOC = 80% DOD<\/strong><\/p><\/li><\/ul>

          Beispiel\uff1a
          Wenn die Batterie 20% voll ist, betr\u00e4gt der DOD 80%.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

              Achten Sie bei der Auswahl einer Batterie auf Folgendes:<\/p>

              • Nenn-DOD (z. B. 80%, 90%, 95%)<\/p><\/li>

              • Zyklusdauer in diesem DOD<\/p><\/li>

              • Garantiebedingungen<\/p><\/li>

              • Szenario der t\u00e4glichen Nutzung<\/p><\/li><\/ul>

                Wenn Sie die Batterie t\u00e4glich benutzen (Solaranlage, Backup-System), w\u00e4hlen Sie eine Lithium-Batterie mit hohem DOD und langer Lebensdauer.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                  Die Entladetiefe (Depth of Discharge, DOD) ist ein Schl\u00fcsselfaktor bei der Auswahl der richtigen Solarbatterie.
                  Ein h\u00f6herer DOD bedeutet mehr nutzbare Energie, aber nur Lithium (insbesondere LiFePO4) kann mit einem hohen DOD umgehen und trotzdem eine lange Lebensdauer haben.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
