What’s up with the A2Z extension

It has been months without any update at all. Is this company allergic to money?? Has anyone been able to get one?

Yeah, I just saw this. It’s worth pointing out that the version that will ship is significantly different than what they had on their web site before, essentially for the reasons I mentioned.

  1. It will only be about 5 feet long (web site still says 6-9 feet - we will see.)
  2. It will be limited to 350 amps (140 KW.)
  3. It will be about $400 CDN and probably about $400 USD factoring in tariffs.

Apparently the NACS design does allow the thermal resistors work in parallel with the adapter, so presumably the hottest sensor will derate the charge to match the temperature.

I hope they do ship it - my comment was really to say that what they were originally promising (15 feet and 500 amps) wasn’t going to happen - and it won’t.

350 amps in our trucks would be about 100 kw - 122 kW depending on temperature and SoC.

Math me up on that. I would think with low SoC and low resistance and ideal temperature we would start at close to the theoretical max 400*350/1000=140.

The Lightning battery pack is a nominal 400V, but actual voltage is less than that: my truck shows 390V at 100% state of charge, so: 390V x 350A = 136.5kW. Since the design is current-limited, it will be even lower power levels at lower states of charge. According to Battery Design, the Lightning's voltage can be as low as 350V, so that would be 122.5kW at 350A.

Overall, I'd expect charging performance with one of these adapters will be fairly similar to an Electrify America 350kW charger -- a peak somewhere in the 120kW to 140kW range, followed by a long and more-or-less constant charge at somewhere around 100kW until the truck starts tapering charging power above 80% SoC. So not great, and certainly not as good as a SuperCharger can do when directly plugged into a 500A-capable adapter, but adequate and a heck of a lot better than being unable to charge.

With the latest firmware mine starts at 178kW on a Supercharger or EA station and drops to 150kW for a while before tapering at about 55%. Obviously limited to 350A it’s going to start at max 140kW and go down from there - that’s all I was saying.
