  • Pending — we've flagged this for verification and it should be double-checked before relying on it.

Federal tax credits

IRS clean vehicle and refueling property credits under the 2022 IRA as modified by the 2025 OBBB.

IRC §30D — New clean vehicle credit (up to $7,500)
TERMINATED for vehicles acquired after 2025-09-30
Verified

West Virginia state fees

Registration base fee plus EV/PHEV surcharges under WV Code §17A-10-3c.

How the WV registration fees stack up

Every passenger vehicle in WV pays the $51.50 Class A base registration. EVs and PHEVs pay an additional surcharge on top of that.

  • Gasoline car: $51.50 total
  • Plug-in hybrid: $51.50 + $100 = $151.50 total
  • Battery-electric: $51.50 + $200 = $251.50 total

The $250-ish figure that shows up in casual sources is the total annual registration for a BEV; the $200 in the statute is the EV-specific surcharge on top of the base fee. Our calculator adds $200 (not $250) to EV annual cost because the gasoline-vehicle comparison already excludes the $51.50 base — we're comparing the incremental cost of going electric, not the total DMV bill.

BEV annual surcharge (added to TCO)
$200/year
Verified
Retrieved: 2026-04-18
The statute specifies $200 for battery-electric vehicles operating exclusively on electricity. At 10,000 miles/year this works out to 2.0¢/mile in state road tax, vs. ~1.4¢/mile that a 25-mpg gasoline vehicle pays at the current WV fuel tax rate.

West Virginia does not offer state-level tax credits, rebates, or purchase incentives for new or used EVs. The only WV-level financial levers are utility rebates (see below), the $200/$100 EV/PHEV annual fee, and any local municipal programs not tracked here.

Appalachian Power (AEP) — residential rates

Southern and central West Virginia. Rates effective December 12, 2025.

Marginal energy rate (used for EV charging cost)
$0.156/kWh
Verified
Retrieved: 2026-04-18
Derived from AEP's own bill examples: 1,000 kWh = $176.43 and 2,000 kWh = $332.13. Subtracting implies ~$20.73/month in fixed charges and a marginal variable rate of ~$0.156/kWh. EV charging is an incremental load, so the marginal rate — not the all-in average — is the right number. Using the all-in average ($0.176/kWh) would overstate EV charging costs by ~13%.

Rural electric cooperatives

Various rural WV counties. Coop-specific rates are not independently verified.

West Virginia has several rural electric cooperatives serving smaller portions of the state. Coop rate schedules generally are not published inline on public websites and require direct tariff retrieval or a member call. For v1, the calculator shows a "contact your coop" card rather than calculating off unverified estimates for users whose ZIP resolves to a coop service area. Generic fallback rate used only when a coop cannot be identified: $0.120/kWh.

DC fast charging (DCFC) assumptions

Rate and time math used for long-trip public fast-charging stops.

Why DCFC deserves its own line

Public fast charging typically costs ~3× more per kWh than charging at home. For a driver who takes 10+ road trips a year, quietly pricing every kWh at the home utility rate overstates EV savings by hundreds of dollars. The calculator now splits BEV energy into home-rate kWh (commute + long-trip “first tank” before departure) and DCFC-rate kWh (mid-route charging stops).

DCFC rate (long-trip kWh)
$0.48/kWh
Verified
Retrieved: 2026-04-18
Chosen as a conservative walk-up default matching the dominant public network on WV's I-64 / I-77 / I-79 corridors. Actual network rates in April 2026: Electrify America Pass $0.43–$0.60, Pass+ ~$0.38 ($4/mo); Tesla Supercharger (non-Tesla) $0.35–$0.50, with a subscription dropping ~$0.10/kWh; EVgo walk-up $0.38–$0.52. Members of any network will pay meaningfully less — this is the no-subscription case.
kWh delivered per DCFC stop
70% of battery capacity
Verified
Source: Industry convention (10% → 80% SoC before taper)
Retrieved: Calculation methodology set 2026-04-18
Charging past ~80% slows dramatically as the charge curve tapers to protect the battery. Most road-trip stops end at 80%. We compute DCFC kWh as (stops × battery_kwh × 0.7), clamped to the vehicle's total annual kWh so it never exceeds total consumption.
Per-stop time overhead
+4 minutes beyond raw 10→80% charge time
Verified
Source: Industry-typical (plug-in, authentication, session init, unplug)
Retrieved: Calculation methodology set 2026-04-18
Each stop's displayed time = (vehicle's spec 10→80% charge minutes) + 4 min of fixed overhead. Real-world networks vary 3–8 min for authentication and session handling; 4 min is a conservative mid-point. Over 24 stops/yr that's an extra 1.6 hours that would be invisible without this adjustment.
Winter DCFC slowdown
+8% annualized charge time (when winter toggle is on)
Approximate
Source: Battery thermal management research (AAA, Recurrent, manufacturer curves)
Retrieved: Calculation methodology set 2026-04-18
Cold batteries throttle DCFC power by 20–40% until preconditioned. Averaged across 4 cold WV months, this works out to ~8% longer DCFC time annually. Only applied when the user's Winter derate toggle is on — the same toggle that adds 12% to annual kWh. A cold-climate driver who regularly preconditions the battery via navigation will see less of this penalty.
Home-charged “first tank” of a long trip
85% of usable highway range, no DCFC cost
Verified
Source: Standard BEV road-trip planning
Retrieved: Calculation methodology set 2026-04-18
The first leg of any long trip starts from home on a full battery — those kWh are charged overnight at the home rate, not at DCFC. Only miles beyond the first tank hit DCFC. Similarly the destination is assumed to have overnight L2 (hotel, family garage, Supercharger near hotel) so return-leg kWh may or may not hit DCFC depending on range.

Vehicle data methodology

How we source MSRPs, EPA ranges, and efficiency for the 43 EVs and PHEVs in the picker.

Vehicle specs are curated — not scraped — from the following sources as of late 2025 / early 2026:

  • MSRPs: manufacturer websites and automotive press for MY2025 base trims. These are approximations; actual transaction prices vary by region, incentive, and trim level. Refresh quarterly.
  • EPA combined range (range_mi): EPA-certified values from fueleconomy.gov.
  • Winter range (winter_range_mi): our derated estimate applying a ~28% haircut to EPA combined range.
  • City/highway efficiency: EPA MPGe-to-kWh/100mi conversions from fueleconomy.gov.
  • Tax credit eligibility flags: historical (pre-OBBB). Retained in the dataset but the §30D credit is terminated for post-2025-09-30 purchases, so these flags no longer drive the calculator's current-purchase output.

We deliberately did not attempt to re-verify every MSRP on the April 2026 refresh cycle. Directional accuracy is the goal — if you're deciding between two vehicles that are $2,000 apart in our data, the right move is to check current dealer inventory in your area, not to trust our number to the dollar.

Three-letter confidence on this one: Approximate across the fleet.

Known gaps and caveats

What we haven't verified, and where users should double-check.

  • Wheeling Power tariffs were not retrievable on the April 2026 refresh; residential rate and customer charge shown are estimates based on parity with AEP.
  • Rural coop rates are estimates; the v1 UI directs coop members to contact their cooperative rather than relying on these numbers.
  • ZIP-prefix service territory mapping between utilities is a heuristic — the real boundaries are account-level and not publicly published in a clean form. A user on the edge of two territories may resolve to the wrong utility; the UI should encourage them to confirm against their actual bill.
  • Vehicle MSRPs are MY2025 base-trim approximations and do not reflect dealer markups, discounts, or incentives. Not individually re-verified this cycle.
  • Tax credit transition rules: if a user is reviewing a past purchase made before 2025-09-30 under a binding contract, the old IRA credit rules may still apply to their filing. This calculator is scoped to current-purchase decisions.
  • Federal §30C cliff: the home charger credit terminates June 30, 2026. Users planning an installation should factor timing into their decision.
