Scheduled Charging Settings

Scheduled Charging Settings

Scheduled charging allows specifying periods where:

  • Charging will always occur
  • Charging will never occur

Scheduled charging periods will override the regular charging settings. In particular, solar tracking will not occur when a scheduled period is active. Also, price and renewables limits are  ignored during an Always Charge period.

Always Charge

Always Charge allows specifying periods where the vehicle will always charge according to the period settings. The period settings are:

Charge Limit

When the vehicle's battery reaches the specified level Charge HQ will revert to the regular settings. For example, if solar tracking is usually enabled, then solar tracking will resume when the specified charge level is reached.

This is useful to enable an overnight "top up" charge to a minimum charge level during off-peak hours. For example:

This example will cause the vehicle to charge between 00:00 and 04:00 until the battery reaches 40%. If solar tracking is enabled then charging will stop when the battery reaches 40%, because there is no solar during the night. Charging will also stop by 04:00 even if the battery is below 40%.

NOTE: Charge HQ does not control the vehicle charge limit. If the vehicle charge limit is below the scheduled charge limit then charging will stop when the vehicle's limit is reached. Charge HQ will display a warning in this case.

Charge Amps

Always Charge periods will charge at a fixed power (amps), as specified by the Charge Amps setting. Notes:

  • Solar tracking is not possible during a scheduled period, unless the Charge Limit is reached, see above.
  • When scheduled charging is active it is not possible to change the charge amps manually.
  • If the amps are changed using the Tesla app or vehicle, Charge HQ will change them back.
  • If you need to change the amps during scheduled charging then tap CHARGE NOW to override the schedule and the amps can then be changed.

Do Not Charge

Do Not Charge periods allow specifying periods where charging will not occur. This is useful for those on time-of-use electricity plans to prevent charging during peak periods.

This example will cause charging to stop between 16:00 and 21:00 each weekday.

Scheduler Operation

When a scheduled period is active a message is shown on the home screen, as shown in this example.

When no scheduled period is active then the default settings apply. This includes solar tracking if enabled. To clarify: it is not necessary to configure Always Charge periods during solar hours if you want to charge from solar - simply enable Solar Tracking.

The scheduler can be overridden manually at any time using the STOP and CHARGE NOW buttons on the home screen.

Scheduler FAQ

Why can't a period span midnight?

Schedule periods must have start time < end time, i.e. they can't span midnight.

This is to avoid confusion caused by day-of-week scheduling. For example, the period 10:00 pm to 6:00 am Mon - Fri would be unclear. Does it start Monday 10:00 pm or Sunday 10:00 pm?
