Started off at 100% and started the trip at 09:45 with temperature of 57F and clear weather, no quantifiable wind. Drove to our first charging stop 114 miles away in Eastland TX. A Better Route Planner (henceforth abbreviated ABRP) predicted I would use 61% battery for this leg of the trip. In reality we used 67%. Elevation change for this leg of the trip was a gain of 950 feet. We arrived with 33.3% remaining at 11:22. So, my driving time for 114 miles was 97 min giving an average speed of a hair under 71 mph. That 114 miles used 37.2 kWh of power for 3.1 m/kWh… not bad for cold weather, and underinflated tires. At this charging stop, the battery was still a bit cold, so charging rate was a bit slower than normal at first, but then ramped up to full speed. I planned to charge up to 66%, during the charge while I was in the restroom the charger faulted out, and my wife in the passenger seat didn’t notice so we lost 9 min of charging and barley avoided the $.40 a min idle fee… then as we arrived at 65% the wife decided she did need to use the restroom after all… to avoid marital disharmony kept my thoughts on her timing to myself and allowed the charge to continue while she completed her mission… finished off the charge at 69.0% with a total charge time of 30 min and a cost of $4.88 Total energy delivered was 20.85 kWh, so charging speed was 41.7 KW and cost per kWh was $.23
Started second leg of trip off at 69% at 12:10 with temperature of 59F and clear weather, no quantifiable wind. Drove to our second charging stop 99 miles away in Sweetwater TX. ABRP predicted I would use 57% battery for this leg of the trip. In reality we used 62%. Elevation change for this leg of the trip was a gain of 700 feet. We arrived with 7.5% remaining at 13:33. So, my driving time for 99 miles was 83 min giving an average speed of a hair under 72 mph. That 99 miles used 35.1 kWh of power for 2.8 m/kWh. We finished off the charge at 80% with a total charge time of 71 min and a cost of $11.26 Total energy delivered was 46.51 kWh, so charging speed was 39.3 KW and cost per kWh was $.24
Started third leg of trip off at 80% at 14:50 with temperature of 71F and clear weather, no quantifiable wind. Due to warmer temperatures (and a wife), using climate control from now on. Drove to our third charging stop 109 miles away in Midland TX. ABRP predicted I would use 64% battery for this leg of the trip. In reality we used 67%. Elevation change for this leg of the trip was a gain of 530 feet. We arrived with 13.3% remaining at 16:23. So, my driving time for 109 miles was 93 min giving an average speed of a hair under 71 mph. That 109 miles used 38.3 kWh of power for 2.8 m/kWh. Charger faulted out once at 61%, but I was with the car so re-starting caused minimal delay. We finished off the charge at 75.3% with a total charge time of 56 min and a cost of $9.10 Total energy delivered was 39.08 kWh, so charging speed was 41.8 KW and cost per kWh was $.23
Started fourth leg of trip off at 75.3% at 17:25 with temperature of 80F and clear weather, no quantifiable wind using climate control due to high temperature. Drove to our final stop at the Hotel in Pecos TX 96 miles away. ABRP predicted I would use 57% battery for this leg of the trip. In reality we used 56%. Elevation change for this leg of the trip was a loss of 200 feet. We arrived with 19.2% remaining at 18:50. So, my driving time for 96 miles was 85 min giving an average speed of a hair under 68 mph. That 96 miles used 32.0 kWh of power for 3.0 m/kWh Charged for free at hotel using Tesla adapter to 100% at 208 V x 32 amps.
Total miles covered this day was 418 miles, using 142.6 kWh at a cost of $25.24, so my over all was 2.9 m/kWh and $.06 per mile.... not as good as day one, but still much less expensive than my Miata.
Bonus content! We stayed two days in Pecos TX in order to do a side trip to Carlsbad Caverns in New Mexico.
Left hotel with 100% charge for 106 mile drive to Carlsbad Caverns, ABRP said we would arrive having used 48% of the battery, leaving 52% for the return trip, and that average speed would be 50 mph. In reality we used 49% on the trip up. I limited speed to 65 mph even though speed limit for much of the trip was 75 mph. The trip up is an 1800 foot elevation gain, so I knew we would have plenty of power for the return trip. Went to lunch when we got back to Pecos TX, and covered a total of 215 miles. Also, speed limits were much higher than the predicted 2 hours each way would suggest. We actually arrived way early for our tour, probably only drove for an hour and 45 min each way. Closer to 65 mph average speed than 50 mph.
