ParqEx EV Charging Integration — Payments & Capabilities

Audience: Property owners/managers, asset operators, and partners evaluating ParqEx EV charging integration.

What This Document Covers

• EV charging hardware ParqEx can integrate with today
  
• Two payment operating models and when to use each
  
• What ParqEx provides on top of charging: reservations, access, enforcement, billing, and analytics
  
• Deployment and data requirements for a fast launch

Integration Overview

ParqEx supports EVSE integration via:

• OCPP 1.6J / 2.0.1: Connect to any compliant charger when ParqEx manages pricing, access, and billing.
  
• Vendor cloud APIs: Ingest session and usage data to synchronize reservations and access when the charger network handles payments.
  

Bottom line: If your charger speaks OCPP or offers a usable session API, ParqEx can unify the experience within a single smart parking platform.

Payment Operating Models

1) Vendor-Billed (Charger/Network Collects Payment)

Definition: The EV charger or its network (e.g., ChargePoint, Wallbox, EVBox/Everon, FLO, Blink, Zaptec, Easee) handles payments at the point of charge. ParqEx manages reservations, access, enforcement, and reporting by syncing session data from the network.

When to Choose:

• Standardized on a vendor network contract
  
• Payments should remain on the vendor platform
  
• ParqEx manages parking inventory, reservations, access control, and enforcement
  

Typical Hardware / Networks:
ChargePoint, Wallbox, EVBox/Everon, FLO, Blink (incl. SemaConnect), Zaptec, Easee

ParqEx Responsibilities:

• EV stall reservations (time-based, recurring, guest, tenant)
  
• Access control (gates/doors) and stall assignment
  
• Parking enforcement (LPR, patrol, digital permits)
  
• Session data sync: start/stop, kWh, duration, statuses
  
• Unified analytics: energy + parking occupancy reports
  
• Notifications: SMS/email/push for reservation windows, charge complete, overstays
  

Vendor Responsibilities:

• Payments, tariffs, taxes, refunds
  
• Energy management within their network
  

Owner/Manager Outcomes:

• Maintain existing vendor billing relationships
  
• Gain ParqEx’s reservations, access, enforcement, and consolidated reporting
  
• Optional reconciliation of vendor payouts with stall utilization
  

2) ParqEx-Billed (ParqEx Collects Payment)

Definition: The charger operates in free or $0 tariff mode. ParqEx captures session data (time, kWh) via OCPP or vendor API and bills the driver—bundling parking and energy in a single invoice.

When to Choose:

• One bill and one customer journey for parking + charging
  
• Flexible tariffs (time-of-day pricing, stay-based bundling)
  
• Unified refunds/credits
  

Typical Hardware (OCPP-enabled):
ABB, Siemens, Alfen, Tritium, Alpitronic, Delta, Autel, Zerova/Phihong, Circontrol, Leviton, Kempower, Wallbox/EVBox models (OCPP-enabled)

ParqEx Responsibilities:

• Reservations + stall access
  
• Live control: start/stop, max current profiles, time windows
  
• Billing in ParqEx: per-kWh, per-minute, per-session, idle-fee, or blended with parking
  
• Taxes/fees: configurable by jurisdiction; itemized statements
  
• Owner payouts: consolidated across parking + energy
  
• Enforcement: unauthorized occupancy, idle overstays, non-reserved use
  
• EV parking analytics: energy usage, charging time, occupancy, revenue, repeat usage
  

Owner/Manager Outcomes:

• Single platform for pricing, billing, payouts, and refunds
  
• Ability to design parking-first products with energy add-ons
  
• Simplified customer support and dispute handling
  

Supported Hardware (Representative & Expandable)

Vendor-Billed: ChargePoint, Wallbox, EVBox/Everon, FLO, Blink, Zaptec, Easee
ParqEx-Billed: OCPP-enabled brands including ABB, Siemens, Alfen, Tritium, Alpitronic, Delta, Autel, Zerova/Phihong, Circontrol, Leviton, Kempower
