[Wayback/Archive] Vehicle-to-Grid: Bidirektionales Laden lässt Akkus am stärksten altern – Golem.de
Dass sich über smartes oder bidirektionales Laden Geld sparen lässt, ist aber kaum zu bestreiten. Das ist vor allem dann der Fall, wenn man den eigenen Solarstrom im E-Auto zwischenspeichert und für den Eigenbedarf nutzt. Doch dem steht die Anschaffung einer teuren Wallbox gegenüber.

C3 C4 From: IEC 60320 – Wikipedia (and yes: I had an old radio in my youth requiring this plug)
I bumped into the reference chart because I forgot the search term IEC 60320, and therefore searching my earlier blog posts on it ².
I did remember C13/C14 (normal appliance couplers) and C19/C20 (higher power device couplers), so I used the query [Wayback/Archive] c20 c19 amperage – Google Search giving me this table: Read the rest of this entry »

Eerst vond ik [Wayback/Archive] Gekleurd stopcontact met randaarde en beschermingsafsluiters en van daaruit [Wayback/Archive] Rob Kalmeijer: Stopcontacten met niet alleen de (historisch) gangbare Nederlandse stopcontacten, maar meteen ook een heel mooie tabel die de algemeen aanvaarde toepassingen van de kleuren aangeeft:
