* Added in some Words about Battery Drain potential.

Mainly pulled from https://github.com/home-assistant/home-assistant.io/issues/16521 and @mabahj.

* Corrected linting error

Tesla instead of tesla.

* Update source/_integrations/tesla.markdown

* Make the scan_interval phrase clearer.

Added in the other option and referred to it as the scan_interval to make the description clearer hopefully.

@ -50,4 +50,15 @@ This integration provides the following platforms:
Tesla options are set via **Configuration** -> **Integrations** -> **Tesla** -> **Options**.
* Seconds between scans - referred to below as the `scan_interval`.
* Wake cars on start - Whether to wake sleeping cars on Home Assistant startup. This allows a user to choose whether cars should continue to sleep (and not update information) or to wake up the cars potentially interrupting long term hibernation and increasing vampire drain.
## Potential Battery impacts
Here are some things to consider and understand when implementing the Tesla component and its potential effect on your car's battery.
- The `scan_interval` determines when to check if the car is awake and new information is available, but the Tesla integration will not wake up a sleeping car during this polling. By default, the polling will occur every 660 seconds. Polling a car too frequently can keep the car awake and drain the battery. Different firmware versions and measurements of Tesla cars can take from 11 to 15 minutes for sleep mode to occur. There is no official information on sleep mode timings so your mileage may vary and you should experiment with different polling times for an optimal experience.
- The car will, however, be woken up when a command is actively sent to the car, such as door unlock or turning on the HVAC. It will then also fetch updated information while the car is awake based on the `scan_interval`.
- The car can intentionally be woken up to fetch recent information by sending a harmless command, for example, a lock command. This can be used in an automation to, for example, ensure that updated information is available every morning. (Note that the command must be valid for that specific car model. So locking the frunk of a Model 3 will not wake up that car).
- You can also toggle the `Update switch` on/off to disable polling of the vehicle completely via automations or the Lovelace UI.
