2. Set Temperature: Differences Between Chosen and External Temperatures

Closely related to the outside temperature is the set temperature. If you’ve set the interior temperature to be much cooler or warmer than the outside environment, the HVAC system will need to consume more energy to achieve and maintain that temperature. For example, keeping the interior at 70°F (21°C) on a day when the external temperature is 100°F (38°C) will consume more battery than if the outside was 85°F (29°C).

3. Duration: How Long Dog Mode is Kept On

The length of time Dog Mode remains active is directly proportional to battery consumption. Keeping it on for ten minutes will consume less energy than keeping it on for an hour. While Tesla batteries have a large capacity, prolonged use of Dog Mode, especially under extreme conditions, will lead to a noticeable reduction in range.

4. Battery State of Charge: Initial Battery Levels When Dog Mode is Activated

The initial state of the battery, when Dog Mode is activated, plays a pivotal role. If the battery charge is already low when Dog Mode is initiated, there’s naturally less available energy to draw from. Starting with a higher charge level provides a larger energy buffer, ensuring that the car can maintain Dog Mode for longer without severely impacting the remaining range.
