  "summary": "When a Level 2 charger install pays for itself vs public charging.",
  "description": "A hardwired Level 2 home charger plus electrician install typically runs $800-$2,500 depending on panel capacity and run length. This calculator compares that upfront cost against the per-kWh savings of charging at home overnight versus relying on public Level 2 or DC fast charging, factoring in any state or utility rebate for home charger installs (many utilities offer $200-$500 rebates to encourage off-peak charging). It answers the practical question: given how much you drive, does the install cost make sense before you just keep using the public network or the included Level 1 cord.",
  "formula": "Net install cost = charger + install − rebate; annual savings = annual kWh × (public rate − home rate); payback = net cost ÷ annual savings.",

    {
      "q": "Is a Level 2 charger worth it if I have a free Level 1 cord?",
      "a": "A Level 1 cord (regular 120V outlet) adds roughly 3-5 miles of range per hour, which struggles to fully replenish a battery overnight after a long commute. Level 2 adds 20-40 miles per hour and comfortably refills any daily driving pattern overnight, which is really a convenience and reliability argument as much as a cost one."
    },
    {
      "q": "What drives install cost variation?",
      "a": "The biggest factor is panel capacity and distance from the panel to the charger location. A garage right next to the electrical panel with available capacity might cost $400-$600 to wire; a detached garage or a panel needing an upgrade can run $2,000-$4,000+. Get a quote before assuming the default numbers here."
    },
    {
      "q": "Do utility rebates for home chargers still exist?",
      "a": "Many utilities offer $200-$500 rebates or bill credits for installing a networked Level 2 charger, partly because it lets them shift your charging to off-peak hours via demand-response programs. Check your utility's EV program page — DSIRE (dsireusa.org) also tracks state and utility EV incentives."
    },
    {
      "q": "Does this make sense if I rarely use public charging anyway?",
      "a": "If you already have workplace charging or rarely drive beyond your home charge, the payback math weakens fast since the savings depend entirely on displaced public-charging costs. In that case, base the decision on convenience and battery longevity from slower, more consistent charging rather than payback period."
