Thermal cost formula
Energy (kWh) = thermal power (kW) × time (hours). Cost = kWh × $/kWh. Precondition while plugged in so this energy comes from the grid (or home solar) instead of your driving range.
Why temperature matters for DC fast charging
Cold packs charge slowly until heated; hot packs may throttle or cool before accepting full power. Automakers often run the thermal system 15–45 minutes before a planned fast-charge session.
Frequently asked questions
Q: Where do I find kW draw? A: Some EV apps show conditioning power; otherwise use 4–6 kW as a planning estimate. Q: Does this include charging? A: No—only thermal management before or during the wait to charge.
