About

Moin, ich bin Andreas, bin beruflich Wissenschaftler (math. Optimierung& KI), habe Informatik&Maschinenbau studiert&einen Dr. in Ingenieurwesen.  Energiewende&Nachhaltigkeit sind momentan etwas, was sich nur Leute mit entsprechendem Geldbeutel leisten können&das finde ich falsch. Ich möchte euch zeigen, wie es mit etwas Arbeit auch günstiger&sogar besser geht&möchte mich dafür einsetzen, dass jeder, der es möchte, auch die Chance bekommt, etwas zu bewirken. Ich habe mir einen 15kWh-Li-Akku aus 1000den gebrauchten E-Bike-&Notebook-Akkus gebaut&selbst eine 10kW-PV-Anlage auf's Carport installiert, einen E-Roller&ein E-Bike aus gebrauchten Lithium-Zellen gebaut. BMS, Überwachung usw. selbst entwickelt & die Hände verbrannt. Natürlich mit Raspberry PIs/Arduinos. Alles Open-Source im Forum ( https://akkudoktor.net ) verfügbar: Also komm vorbei & sei Teil der Community oder stell mir Fragen in einem meiner Livestreams.  Impressum/Disclaimer: https://www.akkudoktor.net/impressum/

Video Description

In diesem Video zeigen wir dir bei der EV-Clinic Berlin, wie defekte Batterien für einen Bruchteil des Preises repariert werden können. Wir gehen tief in die Akku Struktur und die Bauweisen + alles über die Zellchemie, den Aufbau moderner Akkupacks und worauf du beim E-Auto-Gebrauchtwagenkauf wirklich achten musst, um kein Geld zu verbrennen. ** Werbung: Über den Link https://hier.gg/SurfSharkAkku bekommt ihr bei SurfShark 4 Monate gratis und eine 30-Tage-Geld-zurück-Garantie. ** Danke auch an @stefanlenz und ganz besonders auch an die EV-Clinic in Berlin https://evclinic-berlin.de/ viele Grüße Abonniert den Kanal und ein Like tut auch nicht weh :-) Diskutiert in unserem Forum ► http://forum.akkudoktor.net Unterstützt uns gerne finanziell ► http://www.paypal.me/akkudoktor Konto: Akkudoktor IBAN: DE72100180000252345708 ~▬▬▬▬▬▬ Support / Affiliate Links▬▬▬▬▬~ Wenn ihr diese Links verwendet, bekomme ich ein paar % vom Einkauf ab (kostet euch nicht mehr).
