Tesla is behind technologically on their chargers, notably on voltage. The Cybertruck charges faster on Electrify America than it does on Tesla's own chargers:

Alpitronic and Kempower make the best chargers. Alpitronic and Kempower chargers are slowly getting to North America:

Maybe Tesla doesn't need to be in the charger business anymore :)

It was useful while introducing a new product to the market, but now there's plenty of alternatives, standardization, competition and advancements everywhere.

Maybe makes more sense to divest

What is this preconditioning the replies to the tweet mention? Do you have to do something to prepare for those high output chargers specifically?

Batteries charge better when in a certain temperature range, due to physics. If you tell an EV you are heading to a charger, it can prep the battery to the proper temps.

Does that need to be a different temperature for different chargers?

With a more integrated system (e.g. all Tesla hardware involved or simply a charger that can communicate with the vehicle's software), sensors and software may specify what it needs to be in order for charging to commence. Otherwise it's generally an optimization rather than a requirement. The optimal range will depend on the class of the charger (how fast it's able to charge as well as sensors and software), the vehicle in question (the physical batteries themselves as well as cooling/heating systems), and other physical factors.

In general: the faster the hardware can physically charge the battery, the more important temperature becomes.
