Tesla batteries charge fastest at low levels.
10% battery level enables maximum 250 kW charging speeds.
Charging slows dramatically above 80% capacity.
Optimal Charging Approach:
The "shallow charge and go" method saves significant time:
- Charge only enough to reach next station + 15% buffer (more conservative than 10% for unexpected detours)
- Target 20%-80% charge range at Superchargers for fastest speeds
- Avoid charging to 100% at Superchargers (takes 2x longer than 20-80%)
Charging Network Priority:
- Tesla Superchargers (fastest, most reliable)
- Destination chargers (hotels, restaurants - use J1772 adapter)
- Electrify America (with CCS adapter)
- ChargePoint (as last resort)
Networks to Avoid:
- EVgo (reported high failure rates)
- Buc-ee's partnered Superchargers (severe congestion issues)
Real-world charging times (2023 Model Y RWD):
- 12-15 minutes: 20% → 60%
- 22-28 minutes: 20% → 80%
- 50+ minutes: 20% → 100%
Real-world charging times (2022 Model 3 RWD):
- 10-12 minutes: 10% → 60%
- 25 minutes: 10% → 80%
- 50 minutes: 10% → 100%
Frequent short charges make road journeys faster.
