By the way autopilot or FSD is an option you can buy by the month. 200 bucks. So try it...if you don't like it don't buy. I find on road trips it's great. Worth every penny of the 200 bucks. t Tesla DOES make really good EVs. You can tell, because their owners seem to love them despite

I like the driveability quotient and how you got there. Driveability is a far different thing to me (has more to do with the *way* the car drives and handles), so I might call it DCR or drive charge ratio, or Deecer for the acronym phobic. And I would like to see another term thrown in, since

Hey Lawrence, Your example reminds me of a good rule of thumb with wire. The rule of 3. Parallel any two wires of the same gauge and you drop 3 gauges. So two 10's go to AWG 7, and so forth. It's very helpful in winding transformers and motors, but you can get into trouble in some cases in

Well the Solaredge HD wave (and the previous model) use a fixed input voltage at a nominal 380VDC, with a 480VDC max. There is no MPPT, since that is done off-board in their optimizers, that sit behind the PV modules. So you might be able to connect a nominal 380V battery pack to the solar and

Yeah but the problem with the Route de Sol Van is that right now it's stuck in Mexico, having gone from Alaska, south through Canada, and the continental US. They hit some high winds and it tore the solar panels off and did a lot of damage. And the panels are their primary source of energy.

Hi Peri, I've designed an open source BMS and cell packaging system, if you don't want to design your own. You need to source some pretty amazing lithium ion cells for that 53C discharge rate! I think you might end up with a larger battery to get that big C rate. Anyway it's free to use
