Winch - What is the priority?

[Ogre]

Conversation got weird.

There is not going to be a USB powered winch on the Cybertruck. Or any USB accessories aside from the phone type ports on the console.

Seriously, why do you say that?

USB PD on a USB-C port has become the de-facto power connection and charging port for many small handheld appliances from mobiles to fridges.. 120W on USB is actually enough to charge your ebike or scooter even if you wanted too. Don't forget it actively switches the voltages up to 20V, meaning many more larger battery configurations can be used as well. You can even do RV water pumps for showers, power your compressor fridge, fans, lights, even tea makers all work at that power level. There's a whole range of products that would be useful and all via a USB-C PD port from your CT.

Because using tiny connectors in a dirty and dusty environment is epically stupid.

Just imagine for a moment the conditions where you need a winch and it should be pretty obvious how ridiculous this is.

Your truck is buried to the axels in mud, you are filthy and your hands are covered in mud and you are going to use a device that has a connector which can be jammed up with 4 grains of grit.

Hard nope.

Ugh, last time I was camping I got like a grain of sand in the USB-C cable for my phone and it was just kaput.

Um the "USB powered winch" idea was somebody else's joke, not mine, I just confirmed it could "technically work in a pinch" and would be just as fast as a hand winch like these half decent ones:




If you "had to" use a USB PD powered winch a better solution would be to charge a battery powered portable winch.

For example: Using a polymer battery you can achieve 0.5-1kW/kg, so you could have a 7-8kg 2-3kW portable, cable-less winch you can connect anywhere on the vehicle.

To use connect winch to ground anchor, pull tow rope out of winch and attach to vehicle tow hook, press button and set speed on wireless remote. Can use it on any car, can leave it at home when you don't need it, and you can charge it up in about 2-3 hours from flat using USB PD (with a port cover for the dirt), or in 20min from AC plug, and it would work for 10 minutes under full load. Add two swappable batteries for continuous use.

Also a big plus: no high voltage outside of the box for nervous nellies.

Basically an upgraded version of this:




This one uses a 82V 4Ah 330Wh battery.

Warn actually make a baby drill powered one as well, just need a beefier version or some extra snatchblocks.



You can even get some versions for climbing:

That's a job for Optimus

Optimus will be weaker than a human according to EM.

I'm sorry, but what you have to your EVSE is by definition, not household voltage.

And no, it would be more dangerous because it's a live battery, not a system that already has safety cutoffs and breakers and room for more.

Hence, more dangerous.

Alot of handwavium 'oh but I have a special outlet!'.

Well, no Tesla has a special outlet. Maybe the Cybertruck will have some, and I certainly think it would be a good idea for its version of the power-tap-off, but it's not been suggested or demonstrated.

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 of mechanical or electrical engineering? Have you ever used any sort of winch?

Sorry to be blunt, but you are pedalling nonsense and misinformation and then arguing about it with people who obviously know a lot more about this stuff than you do.

Because it's three-phase and not a standard outlet. That's its point.

I wired my own 240v EVSE for my Zero motorcycle. Which answers your next question....

Yes, I do.

And you're pedaling nonsense. What's in the breaker box or delivered to special equipment is not household voltage. What's in the wires to standard level 1 outlets is household voltage.

Let's see you plug your toaster into three-phase instead of household voltage and then tell me again that three-phase is household voltage. Or, actually please don't, because that's super-dangerous.

Give some guys a little knowledge and they get all huffy. Why is it you see a risk, and you want to pretend it doesn't exist?

Sheesh.

Thank you people for turning serious, and maybe even feasible, my USB joke.

Crissa can you please explain to us how you would measure 400V voltage on a 3 phase connector and how on the same connector you would measure 240V?

If you know how to do this you would also understand what we are saying. You need to first understand the nature of "potential " and of "alternating current."

Just as a reminder: we are in Australia not USA, so physics is all upsidedown here...

Thats what we are here for. Making the impossible, late. (EM quote)

It's actually mostly feasible for two reasons, USB PD is actually powerful enough that it can actually charge 24 standard 1A charger phones at once. And two if you use that power to charge a high peak power output battery it can power a decent size winch for a short period, but long enough to get you out of a bog.

Yeah, the joke went "engineer." My friends and I do this all the time. It's fun. One time, it turned into a product and we made a quarter million deploying it for our state DOT, so there's that. Then we sold it to a few cities. I was drinking and making a joke about an RFP they sent out with stupid requirements that were "impossible."

I adopted USB-C instantly when it was possible and never looked back. It does a heck of a lot, some of it "stupid." I power my off-road motorcycle/eBike compressor with it. Why not, it's the most universal port. I can charge my phone, GPS, and fill tires with one connector. I can charge both from and to a portable pack. It's just universal. Same with the laptop; it can give power or get power from anything, and I never carry a "laptop charger" any more.

Wow, except for your politics, I want to be your friend and neighbour. LOL!
