Home vs public DC fast charging
Home charging is the default cost optimization. Public DC fast charging in Mississippi runs about 2.8× the home rate. For 12,000 miles/yr entirely on DC fast, annual fuel cost would be $1824 vs $652 at home — a $1172 penalty. Apartment dwellers and road-trippers should price this in; daily commuters with home Level 2 can usually ignore public chargers.
DC fast rate is a network average (Electrify America + EVgo + Tesla Supercharger + ChargePoint). Real prices vary by location, time of day, and membership tier.
