The second car is usually the moment a 200-amp panel that “felt fine” starts failing the calculation. We do not guess. We add both configured loads to the existing demand and then pick circuit, load-share, or upgrade.
Key Takeaways
- Load-sharing uses one feeder and splits amps when both cars are plugged in.
- Two dedicated circuits need two slots and twice the continuous load in the calc.
- Brand-specific sharing (Tesla Power Sharing, etc.) still needs a listed electrical design.
Pick the electrical method, then the EVSE
Tesla, Emporia, and ChargePoint all have ways to coordinate. The panel does not care about the app. It cares about breaker size, conductor size, and the 80% continuous-load rule.
