I could not get the Tesla app to work to initiate charging here.
Then I looked at the walls and realized they turned this garage into a faraday cage.
An update to my EV energy-sharing (V2X) comparison:
- Tesla’s Model 3/Y manual lists up to 11.5 kW for Powershare home backup, same rating as the Cybertruck
- Added GM Energy PowerShift
Tesla’s solution would lead the pack if Tesla turned on Grid Support for the 3/Y and supported the Powershare Gateway for them. The inverters are already UL 1741 certified.
GM’s system is underwhelming:
- 9.6 kW backup, for outages only
- Needs an offboard inverter plus a battery to start the system in an outage
- NACS-port GM EVs have to swap adapters to switch between charging and backup
The GM inverter is UL 1741 SB grid-certified, so the outage-only limit is a choice

It needs more than that even.

I don't understand how somebody looked at that message and decided that's what they want to display.
It's too much to read in an emergency.
And it doesn't look alerting enough to not hit if you're an idiot in a hurry

Looks like I had the wrong value put in. I noted 275mi instead of 285 (just reviewed the video, that's where it stopped doing 70mph), and 78kWh instead of 81.1.
Must have recorded the time it hit 0%.
That closes the gap to 8.4%.

A major thing to note - all 4 cars returned much less battery energy than the "usable" should - likely due to the cooler temperature.
Looking at efficiency, the Model Y L comes up 8% short.
I suspect my HVAC AC power consumption estimate is too high.
