I would not use the term "block heater", because it does not apply to an EV. You're using internal combustion engine battery terminology.

But a Teals, and any EV, does not use a battery designed from an internal combustion engine.

What you want to ask is: does Tesla, or EV batteries have a heating subsystem, and the answer is yes.

For a more detailed answer:

A Tesla battery, same with most EV batteries, perform optimally when it is pre-conditioned before starting a trip to make sure the battery, and other car systems, are operating within an "ideal range".

When my car is plugged in at home (not a Tesla), I click on a button on the my phone, and the process gets started.

The system can either "warm" or "cool" the battery and its subsystems.

Depends on how extreme the weather conditions are, it may take up to 30 minutes to finish the job.

"cooling" kicks in, when someone is charging their battery, and it gets to 80%. The battery systems will start cooling the battery cells to "coax" them to accept more energy. This is why it takes 15 minutes to go from 10% to 70%, and then another 15 minutes to go from 70% to 80%, and then more than 30 minutes to go from 80% to 90%, and then more than an hour to go from 90% to 100%.

The temperature outside is 25F, and my EV is plugged in front of my house, I will push the button a half hour before I jump in the shower, so it could be ready to go when I'm done.
