EV Charging in New Jersey: What the Numbers Mean
New Jersey's residential electricity rate is 18.2¢/kWh — 2.1¢ above the national average of 16.1¢/kWh, which narrows EV savings somewhat. At that rate, a typical EV (3.5 mi/kWh) costs $624/year to charge at home for 12,000 miles.
Compared to a 30 MPG gas car at $3.28/gal ($1312/year for the same miles), EV home charging saves $688/year — $3,440 over 5 years, before incentives.
Home Charging vs Public Charging in New Jersey
The biggest driver of EV cost is where you charge. Home charging at 18.2¢/kWh is always the cheapest option. Public Level 2 stations average around 45.5¢/kWh — 2.5x more expensive. DC fast chargers run about 36.0¢/kWh. Tesla Superchargers in New Jersey are estimated at 37.7¢–46.9¢/kWh depending on membership.
Most EV owners do 80%+ of their charging at home overnight. If you don't have home charging access, the economics shift significantly — charging entirely at public DC fast chargers would cost $1234/year in New Jersey, narrowing the gap with gas considerably.
