Thanks for the input everyone. I guess coming from an ICE background I just get in and go because there’s always a gas station somewhere. Today it got me thinking about how far from home I could comfortably drive to make it back without worrying about charging somewhere.
After about 4 months and 4,000 miles I've adopted this approach:
A. Within easy round-trip range? i.e. route planner shows 20% battery or more on return. Before leaving, find possible chargers near your destination, also convenient SuperChargers for the last half of the return leg. That way you know your options if energy consumption is higher than you expected.
We live just west of Philadelphia. One afternoon I wanted a short trip. Decided to have barbeque for dinner, but at a suitably distant venue. Jersey Shore BBQ is 85 miles away in Belmar, fit the specs. Battery was below 50%. Plugged in HPWC, dialed up to 72 Amps, realized I would leave home with barely adequate charge. Verified SuperCharger close to 195/NJ Turnpike intersection (Barnes & Noble); another at Wawa just before the bridge to PA Turnpike connector. Battery looked adequate when I arrived. On my return trip, energy diagram forecast about 15% battery on return home. I told myself that I would go to Wawa near the 130 exit from the connector if the forecast level on arrival dropped to 12%. Didn't need to stop, arrived home with 12% battery. Plugged in charger, dialed back to about 32 Amps for overnight recharge. No "range anxiety" because I had options and guidelines. And tasty meat. The sweet potato fries were incredible.
B. Longer distance than a single charge can handle? Identify SuperChargers and alternatives along the route. As another comment mentioned, miles pack in more quickly at low charge level than high.
Our younger daughter lives in DC, our car's range would be barely sufficient for a round trip slightly below the speed limit, plus typical DC congestion. Last Saturday I drove our older daughter and her twin boys to DC for a day with their aunt. I advised our daughter that we would probably stop at Maryland House on the return trip for a bathroom and battery break. The SuperCharger is near the Sunoco station, which is smaller and less crowded than the main structure.
Set the car for optimal range:
- Chill acceleration. Daughter observed that AutoPilot was much gentler in that mode. Milder acceleration also stretches range.
- Range mode.
- SAS set to automatically lower above 50 mph - better handling and aerodynamics.
- Tire pressure about 48 psi when we left. Small percentage range improvement.
The battery was at 100% when I left to pick up our daughter and sons to start the trip. I asked my daughter to locate the Superchargers as we passed the other two rest areas so we could find them easily if we needed them on the return trip. We stopped at Maryland House on our way down for a bathroom break. The car estimated we would reach DC with 52% battery charge. Even though we had relatively high charge, I figured we might as well squeeze more juice into the battery when it was easy. One grandson plugged in the SuperCharger, and we headed to the bathrooms. Add a few minutes to buy a hot dog for the other grandson, then back to the car. Showed a grandson how to unplug the SuperCharger, strapped the boys into their booster seats, and back on the road. New estimate was 62% battery charge at destination. We arrived with just over 50% due to heavy traffic coming into the city.
Long day in DC, the twins were in pajamas for the return trip after dinner. Daughter was reluctant to stop on the way back for fear the children would wake up, so we skipped Maryland House. My fallback was to stop at Newark Delaware rest area if battery looked too low to confidently complete the trip. Traffic was light, we arrived home with about 14% remaining. I raised cruise speed as it became clear we would have enough charge.
No range anxiety, same travel time as an ICE vehicle.
