Also that Dutch bloke thats driving his EV VW Golf around the world ran short of charge and had someone tow him for a while across the Nullabor to top up his batteries, So basically any EV with an A/C motor , which is all factory EV's can be tow charged, I think they should have a decent front tow point & a solid tow would be handy too.

D/C motors dont have regen as it burns out the brushes & commutator ( A/C don't have any contacting parts)

This guy does the engineering and maths of charging a Tesla by towing it.

Sorry mate, as I know that you have done wonders with your converted Land Rover. But this is just completely wrong. I spent a good part of my working life maintaining DC motors where both regenerative and dynamic braking was an integral part of the systems. There is no more current involved with regen than there is with normal running power. I am talking about big traction motors, such as used in locomotives, 800 plus HP.
Even with basic old school control systems it was never a problem. With more modern SCR speed controls the regen is controlled.

Yes, modern AC motors do not have "contacting parts", but that is also a more modern configuration. It is the advance in modern electronic control systems that has lead to this, rather than just being an AC motor.

The discussion relates to EV , not lifts , not locomotives, not ships, There are NO DC motors used in EV that have Regen . I never said it was not possible , and maybe oversimplified why , They have to introduce variable brush timing , or one set of brushes for drive and another set for regen , the switch gear for such is just too heavy / expensive for EV purposes .

Well, I guess that all those years that I worked on DC equipment, both big and small, I was robbing the people that paid me up to to 10k $USD a month to maintain it!

Never ever have I either seen, or heard of, DC motors that have two sets of brush gear! In some applications the field current is reversed, which would require switch gear. Just as you have quoted that AC motors do not have have moving parts is also wrong. Despite the development in electronics and variable speed AC drives, the basic physics of how electricity works has not changed. As for switching, modern electronics can also be used that does not require heavy switch gear.

It has nothing to do with whether the equipment is used in an EV, or the biggest ship on the ocean, my gripe is that statements like you have made that are wrong, just increases the mis-understanding of people that are interested but have had no training.

popcorn time?

I prefer nuts, Dennis.

they get stuck in my diverticules Ian.

haven't eaten nuts since september and I love pistachios

Jaguar going 100% EV by 2025


Sister company to Landrover.....



Jaguar cars will be fully electric by 2025 as the carmaker joins a global race to develop zero-emission models to get ahead of looming bans on sales of new fossil-fuel vehicles. Ciara Lee reports


Then more- The Landrover side- GASP
The company plans to welcome six pure electric variants of Land Rover in the next five years, including the first all-electric Land Rover model in 2024.
“We have all the ingredients at our disposal to reimagine the business and the experiences our customers seek, to reimagine to benchmark of luxury,” chief executive Thierry Bollore told the Associated Press.
In addition to 100 per cent of Jaguar sales going electric, the company expects that about 60 per cent of Land Rovers sold will be equipped with zero tailpipe powertrains.
