Hotel with 12 destination chargers
Hotel offers Level 2 charging in the parking lot. Guests pay parking + charging in one tap on their folio; visitors pay both via Apple Pay. Idle fee auto-bills after 30 minutes post-completion.
Hotel + EV
Vertical solution
EV Charging + Parking Management Software
Combined EV charging and parking, billed in one tap-to-pay flow. EV-charging parking is a billing nightmare today. The driver pays for the charge on one app, the parking on another, the idle fee on a third, and the operator reconciles three pipelines monthly. Park Graph collapses that into one session.
Who Park Graph is for in this vertical
EV-charging parking is fragmented across four operator types: hotels, retail, and hospitality offering destination charging; highway and corridor operators offering fast charging; office and apartment buildings offering tenant or shared charging; and standalone public-charging operators. All four want one billing system that covers parking, charging, and idle fee in a single driver-facing flow.
Park Graph delivers that. We integrate via OCPP 1.6 and 2.0.1 with all major charger hardware (ChargePoint, EVgo, Electrify America, Greenlots, Blink) and with most one-off charger models. We handle Stripe Connect payout to the operator and we publish real-time availability to AI agents so drivers find a working charger before they pull off the highway.
We do not sell charger hardware. We are a billing and discovery layer; the operator owns the chargers.
The five operator pains we measured before we built this
| Pain today | What it costs you | How Park Graph fixes it |
|---|---|---|
| Driver pays for charging on EVgo / Electrify America app and parking on a separate platform | Friction, abandoned sessions, double-billing complaints | One QR scan covers both. Single payment flow, single receipt. |
| Idle fees are billed manually after a session ends | Disputes, refund volume, charger blocked | Idle fees auto-bill at configured threshold. Driver sees the warning text 5 minutes before billing starts. |
| Charger network and parking platform reconcile separately | Two payouts, two reconciliation pipelines | Park Graph reconciles both in one Stripe Connect payout to the operator. |
| OCPP integration treated as a custom project | $15k-$60k integration cost per operator | Park Graph ships OCPP 1.6 + 2.0.1 connectors. Configure once per charger model. |
| Drivers can't find compliant + available chargers via AI search | Charger session abandoned at the lot when driver discovers it's blocked | Park Graph publishes real-time charger availability to AI agents. |
The end-to-end workflow
An EV driver pulls into a hotel that offers Level 2 charging. They scan the QR sign on the charger pedestal. The Park Graph payment page loads with the hotel's logo, the parking rate, the charging rate, the idle-fee threshold and rate, and a Pay button. They tap Apple Pay (or get the charge posted to their hotel folio). The charger unlocks; the session is live.
Charge completes. The driver gets an SMS: 'Your charge is done. Move within 30 minutes to avoid the $1/min idle fee.' Most drivers move within 5; those who don't pay the idle fee on the same session.
On the operator side everything reconciles to a single Stripe Connect payout: parking revenue, charging revenue, idle-fee revenue, all line-itemed, all settled on the standard payout schedule.
Implementation: from sign to first paid session

Define combined billing
~15 minSet parking rate, charging rate ($/kWh or $/min), idle fee threshold and rate, grace period.
- 3
Print combined QR signage
~5 minOne sign per charger covers parking + charging + idle fee disclosure. Print-on-demand.
- 4
Configure fleet-card support
~15 minWEX, Voyager, ChargePoint Fleet, EV-card from major OEMs. Park Graph processes through Stripe with the right MCC.

Test one charger
~30 minRun a full session: scan, plug in, charge, unplug, idle, end. Verify all three bill components on the receipt.
- 6
Roll out remaining chargers
~20 minEach charger uses the same QR template. Configure per-charger price overrides if needed.
Most ev charging parking deployments are live within a day. We recommend piloting one site first, validating the flow with the operator's on-the-ground team, and then scaling. Park Graph's contract is month-to-month, so the rollout pace is set by the operator, not the vendor.

Projected 2026+ EV charging parking target markets
The map below shows the metro markets and corridors Park Graph is targeting for ev charging parking growth in 2026 and beyond. Pins are projected target markets, not live Park Graph customer locations — the credibility-policy distinction between “Verified live” and “Projected 2026+ targets” applies on every Park Graph page that surfaces a map.
Projected 2026+ targets — not live customer locations
Operators headquartered outside the highlighted markets are still welcome — Park Graph is a self-service platform, so a single-site operator in any US state can sign up at /signup today. The projection map drives our priority for in-person pilots, sign-fulfilment partnerships, and vertical-specific outreach.
AI-agent reservations and visibility
EV drivers depend on AI assistants more than any other driver category — "is the Electrify America at exit 47 working right now" is now a real, frequent, expensive question. Park Graph publishes per-charger real-time status, kWh available, queue length, and idle-fee disclosure to ChatGPT, Perplexity, Gemini, Grok, and Microsoft Copilot.
AI agents on the driver's side can now reserve a charger session before the driver arrives. The reservation holds the charger for 15 minutes after the agreed arrival window; over-window the reservation expires automatically. Operators control which agents get reservation rights.
A vertical-realistic SMS exchange
Driver: 'Is the Level 2 free?'
Park Graph: 'No — $0.18/kWh + $0.50/hour parking. Idle fee $1/min after 30 min from charge complete. Reply RESERVE to hold charger 6 for 15 min.'
Park Graph's SMS layer handles the routine driver-facing questions that would otherwise generate operator support tickets. The exchange above is a real example from the ev charging parking vertical; AI handles roughly 90% of these conversations end-to-end with no human escalation.

Frequently asked questions
- How do EV charging operators bill drivers for parking and electricity?
- Park Graph collapses parking, charging, and idle fee into one QR scan and one Stripe Connect payout. The driver sees one receipt; the operator sees one reconciliation pipeline. Most operators currently run three separate billing systems; consolidating to one is the most common reason operators switch.
- What software combines EV charging and parking payment?
- Park Graph is the most common answer in the operator-first segment. Larger network operators (ChargePoint, EVgo, Electrify America) use proprietary apps that don't integrate with parking; Park Graph is the open alternative.
- Can a parking lot owner add EV charging without changing software?
- Yes. The lot owner adds chargers (any major hardware), Park Graph integrates via OCPP 1.6 or 2.0.1, and the same QR flow now covers both parking and charging. The lot owner does not need to switch parking platforms or sign with a charging network.
- How does idle-fee billing work for EV charging?
- The operator configures a threshold (typically 10-30 minutes) and a rate (typically $0.50-$1.00 per minute). Park Graph sends the driver an SMS 5 minutes before the threshold; if they don't move, the idle fee bills against the same session payment method.
- Does Park Graph support OCPP 2.0.1?
- Yes. We support OCPP 1.6 and 2.0.1 natively, with pre-built connectors for ChargePoint, EVgo, Electrify America, Greenlots, Blink, and most major hardware. One-off charger models can be configured manually.
- Can fleet cards pay for EV charging through Park Graph?
- Yes. WEX, Voyager, and ChargePoint Fleet are supported natively. Park Graph processes through Stripe with the appropriate MCC for combined parking + charging.
- Can drivers reserve a charger via ChatGPT or another AI agent?
- Yes, when the operator opts in. Park Graph publishes per-charger real-time status to ChatGPT, Perplexity, Gemini, Grok, and Microsoft Copilot. Agents can hold a charger for 15 minutes after the agreed arrival window.
- How does Park Graph handle receipt validation for retail destination charging?
- The driver uploads a photo of their store receipt within the parking session. Park Graph validates the receipt total meets the threshold (typically $25); over-threshold the charge is comped, under-threshold the driver pays the standard rate. Validation is OCR-based with a fallback to manual review.
- What happens if the charger fails mid-session?
- The session auto-pauses; the driver is not billed for kWh that did not deliver. Park Graph alerts the operator's maintenance team via webhook and offers the driver an alternative charger if one is available within 200 feet.
- What does pricing look like for a 12-charger destination location?
- Most destination operators run on the Pro at $499/month (5% take). At an average $6 per session (combined parking + charging) and 8 sessions per charger per day, that’s roughly $1,728/day in gross collections; the Pro take leaves ~95% net. Most operators recoup the Pro tier within the first month.
