lab-update-40-e-touran-120-km-h-energy
Today I take out the Touran on a stretch of Autobahn to measure its energy consumption at 120 km/h in summer temperature. I'm trying to replicate the procedure of "TeslaBjörn" from Norway to obtain a result that is kind of comparable to his impressive list of vehicle tests.

Finally Audi delivers itself to Thomas who will drive it everyday. On the 350 km trip we did 6 "quick" charge stops. We needed just 45 kWh for the trip resulting in a whopping 128 Wh/km.

lab-update-63-deutsch-nulleinspeisung
Heute schauen wir uns meine Balonsolaranlage nebst Speicher an. Im englischen Video wird auch der Speicher vorgestellt, anonsten ist es identisch.
A similar video is available in English: https://youtu.be/yRdmdMXRrWw
Kosten:
- 4 Solarpanels + Reste (1400Wp): 460€
- 2 PV-Wechselrichter: 300€
- 1 Batteriewechselrichter: 160€
- 1 Ladegerät: 250€
- Kleinkram: 150€
Die 2 kWh Batterie war eine Spende, ansonsten dürfte sie für 300-400€ zu haben sein. Also ca. 1700€ für alles. Ich denke damit kann ich ca. 1000 kWh im Jahr einsparen, was 400€ entpricht.

When installing the new battery I forgot to properly tighten some bolts and had fitted some dodgy cable extensions. In Mathieus workshop in Hamburg I fixed those issues and now go for a test.
