Hansshow NACS to CCS1 Extension Cable

[NW Ontario Ford Lightning]

lots of them around here...hope they expand them over the next few years...
From my recent trip - I charged in Ignace Ontario ( a tiny northern town on the TransCanada Hwy system). From an online search:

Yes, there is a Tesla Supercharger (DCFC) station in Ignace, Ontario, located at the Ignace Town Plaza, 304 Main Street. The station features 6 Superchargers capable of up to 250kW and is available 24/7. This Supercharger is compatible with both Tesla vehicles and NACS-enabled vehicles with CCS capability.

During my trip to Winnipeg, there were sets of 6 Tesla DCFC in Ignace, Dryden and Kenora (Ontario) and in Prawda Manitoba. In the City of Winnipeg at Polo park mall that Tesla location was 8 chargers - multiple of 4 on that one. When I last travelled East all the Tesla stations where I charged were sets of 6.

In Canada we use different voltages than USA, ie your common 480volt AC is not used here generally, instead we use 347/600V 3P as a very common commercial voltage and above that is outside my experence, but I hear electricians discussing 4160v quite often. I suspect that a typical commercial service can support 6 Tesla EV fast charges, since this seems to be the common set up around here.

How do you limit the rate to 250A (100KW)?

Temperature ?

Temperature ?

Let us know how that works out.

Let us know how that works out.

It seems the truck already uses temperature monitoring in the charging system to reduce charging rate, from what we have seen on the forum. ie this is why you start off on a DCFC at very high current but only for 6-12 minutes or so, then it gradually reduces. The extension cord will increase resistence and therefore temperature and the truck will respond ? yes/no?

The sensor is in the charge port. The truck (or the charging station) has no clue what’s happening along that extension cord.

The normal throttling you observe is either part of the charge curve or battery thermal management. Under normal operation, throttling due to over temp at the charge port does not occur. In fact, a charge port over temp sets a DTC.

A side note for Tesla Supercharger station cord evolution... I just completed a 9,300+ mile two month trip during which we used Tesla as well as CCS DC Fast charging stations, as needed.

We actually tripped into two (out of at least 20) Tesla locations where the Supercharger cords were of "CCS normal" useful lengths... so Supercharger cord change IS coming, albeit slowly.

You could not pay me to put a Hansshow product in the DC charging path of my truck. Here is some perspective on Hansshow: https://www.f150lightningforum.com/...772-80-amp-recommendations.18270/#post-367005

I wouldn't be concerned, personally, about any 'safety' issue, as these connections look very secure and beefy, just like the NACS plug and the Adapters we already use... but, I'll in no way be paying that kind of price for such a short cable, and very, very infrequent 'need' for one...if ever. I've never had any issue finding a way to reach a Supercharger cable... even with our camper in tow.

The Hansshow "80A" AC charging adapter *looks* very "secure and beefy" too, but as noted in the post linked above, when disassembled (or when it disassembles itself, also as described in the linked post) it turns out to be incredibly dangerous garbage. And Hansshow clearly know it, too, since they won't provide meaningful support (an invitation to connect on some sketchy Chinese chat app and then complete refusal to assist by email or phone). My guess? They are probably trying to limit the exposure of anyone in the US or Europe associated with their products so when they finally burn someone's house or car to the ground, they have a better shot at avoiding liability.

Just the specs of this CCS extension cable - which I'd strongly suspect it does not meet - are hair-raising. Rated to 250A when there's no way it can enforce that, and most 400V vehicles at a compatible Supercharger will draw far more?

Another one of this company's big products was a powered-open kit for the Tesla frunk that jammed people's hood open so they couldn't drive. Trust them to safely put 200kW of power into the charge port of my truck? Thanks, no.

In other news they apparently tried to bribe @branden to take down his video.

I was able to find some pictures of the Ignace site on the Tesla supercharger.info site. I looks like they are only running 3 dispensers per cabinet based on the conduit runs. They also have 2 transformers at the site so each cabinet seems to get its own. I wonder if it is something uniquely Canadian or if there are 6 dispenser sites in the US. I have some new questions for the next time I talk to my Tesla experts.

Yes they are probably secure but if you push the button on the NACS end it will allow you to unplug it. If you do that without stopping the charge you could get an arc flash which best case burns you and worst case kills you. The solution is a 10 cent microswitch that they seem resistant to adding.

Price alone made me shudder from buying it considering it's length.

Same here I’m not gonna sell out $600 for 5 foot cord

Update to this extension cable issue. New video by Tom on a longer better quality Hansshow extension cable.



Looks to be a good solution for towing, or if you regularly charge a a very busy Tesla location.
What I thought I wanted a year ago, I probably will not buy now, especially at the price.

Now if I could rent this cable I would probably do that occasionally.

Say if U-Haul offered it on a daily or weekly rental, pick it up and drop off at any dealer ...

Perhaps $20 for one day would be reasonable, say $50 for a week??

$600 is pretty steep, but it looks like the original safety issues have been addressed. Tom's test with the Lightning and Rivian charging on the cable back to back without speed decreasing or heat issues is pretty solid. He admits that winter temps are favorable, but the cord quality still looks good.
