Tesla Wall Connector bootloader bypasses the firmware downgrade ratchet

One thing I'm really scared of is EV charger software being modified by users, hackers or bugs to pull max power at times that don't suit the grid.

In the UK, for example 10 million EVs all pulling 7kw would overwhelm the roughly 70GW potential of the grid. Even a million EVs charging at an inconvenient time could add a 7GW draw which is enough cause a problem.

PSA: If your wall connector loses wifi, it'll just throw your charging schedules out the window and turn on/off sporadically. This is especially noteworthy if you have Time of Use billing :| SET THE TIMER ON THE CAR DIRECTLY!

Why use Tesla wall connector in a first place and not just the standard nema/dryer outlet with the Tesla cord/charger? It seems like people are overpaying for nothing.

I hate the gen 3 wall connector.

It creates a wifi access point in your garage that you cannot turn off:

  TeslaWallConnector_<unique-id>

I would love to be able to hack any firmware to disable that.

I also read that a connected tesla car can force an over-the-air firmware update maybe through the charging cable or wifi, but I haven't verified that.

Repeat after me:

An owner voluntarily downgrading firmware to gain control of your hardware IS NOT A HACK.

And if an adversary is doing this, then they have already breached yoir physical security.

Why would I want to hack the bootloader for a wall charger? Asking for a friend
