It is not clear to me which side the anode and cathode oh diode “D3” should face. Is the anode supposed to be closest to “C40”?


Remember this common mnemonic: ACID , that stands for "anode current into device"
Now. Look at the PCB. You will see that the anode of 'D3' faces the cathode of the ...

Thank you for sharing, fabulous work! So exciting to see the progress!

Please don't lets get hung up on this high voltage thing.
More voltage is only required to counter the back emf as the motor increases speed.


True enough but I'm guessing running it from ~300V it will have have about half the speed and power capability?


No. Not necessarily.
To make ...

Welding leads are suitable, and you can obtain in bulk by the .25 meter from welding supply shops. Orange conduit is also a good option since the orange rubberized coating usually costs much more than the standard black (or sometime green) that the cables usually come coated in from the welding ...

Ah yes! Lest we forgot about Weber. Thank you for the reminder.

So this is only for cost/labor saving?


As you may find in reading the material; the research paper presents a novel way –with little to no extraneous apparatus needed, to quickly and efficiently heat the traction battery from −30ºC to 15ºC in as little as 5 minutes!
This in comparison to ...

It turns out, the lower the frequency, the higher the current.

Fascinating!

Read the paper this evening. Good science there. Great find! Thank you for the introduction to this principal.
