Can you please stop commenting on things that you obviously have no idea about? How is my EVSE not household voltage. It is fed from the same bus rails that power the rest of my house, at the same voltages as well. Do you have an EV? Do you actually know how they work? Do you have a knowledge...

I agree that any sort of brushed motor, in particular the series wound motors found in 12-24V DC winches is very unlikely. The brushes would not last long and having no control of the winch speed would make high power dangerous. For a company that makes power electronics every day, a simple...

I too am in Australia and have 3 phase 415V in my house. My Tesla HPWC is set up with 32A 3Ph, so 22kW (which is my hope for the on board charger on CT to make Outback touring easier) As to the danger of this, do you know what these voltages are referred to by electricians? Anything under 600V...

Based on what though? Small EV (~10kW) drive units are common these days, usually around the 120VDC but easily changed to 400VDC, and that is literally all that is required. There is nothing complex or dangerous about this. The rest of the winch is just based on typical recovery winch of the...

Having used my winch for self recovery and other purposes far more than I would like, I would definitely pay money for a good HV variable speed winch over 12V junk. I have been in situations where winch after winch is overheating because a convoy is stuck at the bottom of a valley because it...

I don't think that this is as hard as you think. There are numerous items powered from the HV pack. The heat pump compressor, the 12V inverter, 110/240V AC inverter and so on. The winch should just be another load. My ideal would be a 5-10kW 3 phase AC motor with variable speed inverter powered...

Funny, I was just using this graph today to estimate ideal speed when travelling long distances supported only by AC charging. Interestingly, for the scenarios that I was testing for my M3P, 500-1000km/day it is better to drive faster and charge longer (at 70km/h 11kW rate) than to mind your...

Lots of talk about battery longevity, but nothing about performance. So, to add to the conversation I have a Model 3 Performance and I notice that maximum acceleration is only achieved at over 80% SOC, with 90-100% being very savage indeed. Based on the typical voltage curves for these...

I too would love this. It would not be too hard to build a roll-out array on a trolley with up to 10 panels on it for a 2.5kW-3.2kW DC string. This would probably be good for 15 km/h charging. In Australia, on many of the truly remote routes you are lucky to do 40km/day so taking a camp day...
