❓Frequently Asked Questions: EV Charging & Wallbox
Key engineering benchmarks, economic ROI, and clean energy incentives at a glance:
Why is a 240V Level 2 charger preferred over a standard 120V outlet?▼
A dedicated 40A or 48A Level 2 wallbox adds 25 to 40 miles of range per hour, compared to just 3 to 5 miles per hour on a standard 120V household outlet.
What electrical service upgrade is needed to install a Level 2 charger?▼
Most Level 2 chargers require a dedicated 40A to 60A 240V dual-pole circuit breaker. Homes with older 100A main service panels may benefit from smart load-shedding switches.
Does frequent Level 2 home charging degrade an EV battery faster?▼
No. Level 2 AC charging is the optimal charging method recommended by manufacturers. It causes far less thermal stress and battery degradation than public DC fast chargers.
What is solar surplus EV charging?▼
Surplus charging monitors home power flows in real time and routes only unconsumed rooftop solar directly into the EV battery, minimizing utility grid imports.
What are the cost savings of charging an EV at home versus fueling gasoline?▼
Driving on residential electricity averages $0.04 to $0.06 per mile, compared to $0.14 to $0.20 per mile for a 28 MPG gas car, saving $1,200 to $1,800 annually.
What is bidirectional EV charging (V2H or Vehicle-to-Home)?▼
Bidirectional charging allows an EV battery (often 60 to 100 kWh) to send power back into the house during an electrical outage, acting as a massive whole-home backup battery.
