Sizing the circuit, months ago
Charger speed is capped by the circuit, the circuit by panel headroom, install cost by the cable run. Four honest inputs decide the whole project. Run yours:
One ordinary night of Level 2 home charging, logged truthfully, with the one planning decision that makes every night after it boring in the best way. Range anxiety is a public-charger problem; your driveway does not have it.
Charger speed is capped by the circuit, the circuit by panel headroom, install cost by the cable run. Four honest inputs decide the whole project. Run yours:
The car and the wallbox negotiate amps between themselves. Chargers that paywall scheduling behind an app subscription are selling you a feature your car already has, which is why they are disqualified here regardless of discounts.
Off-peak tariffs do the same driving for roughly half the money. Scheduling to the tariff window is the single highest-yield setting in the whole setup, and it is free.
The install path behind this boring miracle: an electrician load-calculates the panel, runs the circuit (distance and walls set the price, not the charger brand), and hangs a dumb reliable box. Most 200 A homes fit a 40 A circuit without upgrades; many 100 A homes want a load-share device instead of a new panel.
