FAQs
Head terms: home EV charging, EV home charger, residential EV charging, portable EV charger, Level 1 vs Level 2
At home you’ll typically use AC charging:
Level 1 (120V, North America)
Uses a standard household outlet. Slow but simple. Good for low daily mileage or overnight top-ups.
Level 2 (240V single-phase / 230V in many regions)
The mainstream choice for home: commonly 3.6–7.4 kW on single-phase; 11–22 kW where three-phase is available.
DC fast charging at home
Rare due to cost, power requirements, and noise/space. Most homeowners don’t install DC fast chargers.
The OBC bottleneck
Your EV’s on-board charger (OBC) caps the AC charging rate. If the car’s OBC is 7.4 kW, a 22 kW wallbox won’t make AC charging faster.

Head terms: EV charging time at home, how long to charge an EV at home, Level 2 charging time, 7.4 kW charging time
Simple formula:
Time (hours) ≈ (Energy to add in kWh) ÷ (Effective power in kW)
Where:
Energy to add (kWh) = Battery capacity × (Target SOC − Start SOC)
Effective power (kW) = min(charger power, OBC limit) × efficiency factor (≈0.9)
Assumptions: efficiency 90%; OBC ≥ charger power.

Head terms: home EV charger installation, EV charger permit, panel upgrade for EV charger, 240V EV charging, NEMA 14-50 (NA), single-phase vs three-phase (EU/UK)
A safe, compliant install protects your panel, property, and warranty. Plan with a licensed electrician and match your plug standard (e.g., J1772/Type 1 in North America, Type 2 in much of Europe; NACS is emerging in NA).

Connector choices: J1772 (Type 1), Type 2, CCS1/CCS2 cables, and NACS adapters/cables—match the car and region.
Head terms: smart EV charging, scheduled EV charging, load balancing EV charger, off-peak EV charging, night rate EV charging
Time-of-Use (TOU) / Night rates: Shift charging to cheaper off-peak windows.
Scheduler: Set start/stop times or departure time to pre-condition and finish near departure.
Load balancing: Coordinate with big appliances (HVAC, oven, dryer) to avoid nuisance trips.
Solar matching (optional): If you have PV, align charging with surplus generation.
Small settings, big wins: For many households, simply avoiding 4–9 pm and charging overnight yields most of the savings.
Head terms: EV charging in apartment, condo EV charging, no driveway EV charging, curbside EV charging, shared garage EV charging
Workplace / community chargers: Leverage daytime parking.
Condo/HOA retrofits: Metering and billing policies can enable assigned-spot charging.
Shared garages: Portable Level 2 on a dedicated, compliant outlet can bridge the gap (follow building rules).
Curbside / municipal: Check local programs near multi-unit dwellings.
Safety first: Don’t run cables across sidewalks. Use approved routes and enclosures.
Head terms: best SOC for daily charging, charge to 80 percent, EV charging safety at home, outdoor EV charger IP rating
Everyday target: Many owners set ~70–80% for daily driving.
Trip days: Charge to 100% right before you leave.
Avoid deep cycles when possible; keep the pack temperate.
Outdoor gear: Look for appropriate IP/weather ratings and strain relief on cables.
When in doubt: Consult your vehicle manual and a qualified electrician.
Head terms: EV charging with solar, solar EV charger, home battery and EV, V2H/V2G home charging
PV + EV: Maximize self-consumption by timing charging with mid-day solar (or schedule at night if tariffs are cheaper).
Home batteries: Buffer solar for evening charging; weigh cost vs. tariff savings.
V2H/V2G: Emerging options that require compatible vehicles, bi-directional hardware, and utility approval.
How long does home EV charging take?
Use Battery kWh × (Target − Start) ÷ Effective kW.
Is a 7.4 kW home charger enough?
For most households, yes—especially with overnight charging. Your car’s OBC may cap AC speed anyway.
Can I use a regular outlet?
Level 1 (120V) works for light daily use. Ensure the outlet and circuit are in good condition and appropriately protected.
Do I need a permit?
Often required for new circuits or panel work. Check local rules and use a licensed electrician.
J1772 vs Type 2 vs NACS—what do I need?
Match your region and vehicle inlet. Many North American cars use J1772 for AC (NACS emerging); much of Europe uses Type 2.
What’s the cheapest time to charge?
Usually overnight off-peak hours on TOU plans. Use scheduling to automate.
