EV Charging 101: How Home Charging Actually Works
Everything a first-time EV owner actually needs to know — the levels, the plugs, the amps — in one straight read.
The three levels of charging
Level 1 — the wall outlet
120 volts · 3–5 miles of range per hour. Any standard outlet. Fine for plug-in hybrids and short commutes; painfully slow for a full EV with a long drive.
Level 2 — the home standard
240 volts · 25–45 miles of range per hour. A dedicated circuit — hardwired charger or NEMA 14-50 outlet. A full charge overnight for virtually every driver. This is what we install.
DC fast charging — the road-trip stop
Public stations · up to 80% in ~20–40 minutes. Not a home product — the equipment and power demands are commercial. Great on the road, expensive per mile compared with charging at home.
What a home setup actually includes
- A dedicated 240V circuit from your panel to the garage, sized for the charger
- The charger itself ("EVSE") — wall-mounted, hardwired or plugged into a NEMA 14-50 outlet
- A load calculation proving your panel can carry it — required by code, and how we size things
- A permit and inspection in Fresno, Clovis, Madera, and every city we serve
- Setup — Wi-Fi, the charging app, and a schedule matched to PG&E's off-peak hours
Plugs, in 2026 plain English
Two connectors matter. J1772 is the long-time standard plug on most non-Tesla EVs. NACS is Tesla's plug — and most automakers are switching to it on new models, with adapters bridging the gap both ways. Either way, the circuit in your wall is the same; only the charger's cable end differs. Buy the car you want — the charging side is solvable.
Amps, simply: the charger draws current (amps) from the circuit. A 40-amp charger needs a 50-amp circuit; a 48-amp charger needs 60. Bigger isn't automatically better — once you can refill overnight, extra amps buy nothing. We size to your driving, not to a spec sheet.
The habit that makes it cheap
Charging at home on PG&E's EV2-A time-of-use rate — with the charger's schedule set to the overnight off-peak window — costs a fraction of gasoline per mile, and far less than public fast charging. Set it once and the car quietly fills while you sleep. It's the entire economic argument for home charging, and it's why the setup step matters as much as the install.

Quick questions
How long does it take to charge an EV at home?
On Level 2, most EVs add 25–45 miles of range per hour, so a typical overnight session replaces 200+ miles — more than almost anyone drives in a day. On Level 1 (a regular wall outlet) you get roughly 3–5 miles per hour, which suits short commutes and plug-in hybrids.
Can I plug my EV into a regular wall outlet?
Yes — that's Level 1 charging, and every EV can do it. It's slow but safe when the outlet and circuit are in good shape. Have an older garage outlet checked before relying on it nightly; continuous loads are hard on worn receptacles.
What charger should I buy?
For most homes: a 40-amp plug-in unit on a NEMA 14-50 outlet, or a 48-amp hardwired unit if your panel supports it. Tesla owners can use a Wall Connector or the Mobile Connector; everyone else should look at J1772 units — and note that newer EVs are moving to the Tesla-style NACS plug, so a charger with a swappable cable or adapter story ages best. We'll spec the exact model during your assessment.
