Scheduled Charging Settings

Charge Schedule

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

Charge Limit

The Charge Limit setting is only available for Tesla Vehicles. It's not currently possible for smart wall chargers to communicate the charge level of a vehicle battery. Learn more.

When the vehicle's battery reaches the specified limit Charge HQ will stop charging, unless another setting causes charging to start. For example, if solar tracking is enabled, solar tracking will resume after the specified charge level is reached if solar is available.

This setting 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%.

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

Scheduled charging will occur at a fixed power (amps), as specified by the Charge Amps setting.

Charge Amps is set per phase. For 3 phase chargers, setting Charge Amps to 16 amps will result in charging at 3 x 16 amps.

Note:

• Solar tracking is not possible during a scheduled period, unless the Charge Limit is reached.
• 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, tap CHARGE NOW to override the schedule and the amps can then be changed manually.

What happens outside of schedule periods?

When scheduled charging is enabled, charging will stop outside of schedule periods unless another setting causes charging to start e.g. solar tracking.

Scheduled charging and solar

If you use solar tracking, you don't need to create charging schedule periods during solar hours. If you create schedule periods during solar hours then the vehicle will charge at a fixed power instead of adjusting the power to match the available solar.

Blockout Schedule

The blockout schedule allows specifying periods where charging will not occur. This is useful to override other controls (e.g. solar tracking or price) during peak tariff times.

The blockout schedule is only useful if you use solar tracking or grid price or renewables limits.

‍

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 other settings apply. This includes solar tracking if enabled. To clarify: it is not necessary to configure scheduled charge periods during solar hours if you want to charge from solar - simply enable solar tracking.

The schedule interacts with the control mode as follows:

• During a schedule period, selecting STOP or CHARGE NOW will override the current schedule period.
• If STOP mode was selected and then a Scheduled Charge period begins, the control mode will revert to AUTO and charging will occur.
• if CHARGE NOW mode was selected and then a Blockout Period beings, the control mode will remain on CHARGE NOW and charging will continue.

The above behaviours are designed so that when there is any doubt of the user's intentions, the vehicle will charge. If you need to temporarily disable an overnight scheduled charge period, you can disable scheduled charging entirely or simply not plug the vehicle in - selecting STOP will not prevent the scheduled charge from occurring.
