On a tangent, I've been spending the past month looking to see any form of charging I can do from a solar panel to the car without conversion losses and coming up blank. The battery is DC, the panel is DC; but you can't do direct DC charging at home, so you end up with DC -> AC -> DC.
It would be nice to get that last 20% efficiency back but I haven't found it.
- jtriangle 3y agoYou'd have to be able to convince the car that you're able to provide DC charging. Far from an impossibility, but a very roll your own kindof system, and you'll likely need some beefy DC/DC converters to do so. You could also, similarly, subvert the car entirely and just disconnect it from the car, charge it from the panels/DC converter, and reconnect it when finished.
- ChrisMarshallNY 3y agoI'm pretty sure that superchargers are DC.
- jbm 3y agoUnfortunately they don't sell supercharger components at home (and I won't be installing a battery to get that 150kw capacity at home). On a side note, I don't want to necessarily fast charge the car; I just want to use the electricity from my solar panel in the most efficient possible way; that would be heating water, powering stuff in the house and charging my car; the last of which probably would take the most electricity.
