Re: Spot market prices in Germany

Winter solution is hydro via reservoirs.

Dams usually take multiple years to fill. A 6 month seasonal swing is nothing. Doesn't even need a river, just a high and a low, pump back and forth. Flooded mines, etc. Spend half a year banking for the winter.

Re: Bunky the eBug: A 30 Day EV Conversion

Just be aware that having lots of weight upfront makes the steering really heavy. I've tested it with 75Kg, and that made a very big difference. It was just about acceptable, but testing with with 96kg (8 x VDA355 modules) was really not.

This has got to be the nicest, tidiest solution to an EV driveline conversion I've ever seen.

Just some gorilla-fabbed brackets and whatever you're going to do for the axles, and it's done.

Other than that my driveline is from 1 or 50 of the first electric sportscar ...

12v and 10a is only 120w. I don't know that that's enough to turn over the motor.

Re: Compatible motors for Prius inverter gen 2

Motor and inverter choice should be agnostic. You can use it to power anything if you configure it correctly. It's just a waveform and a resolver for feedback.
