Mckee White Dew 150KW DC EV Charger Offline Cloud Dual Billing With Payment Gateway

Revenue continuity is the single most sensitive point in charging station operation. The White Dew 150kW DC charger therefore supports two independent billing modes at the same time: a local offline settlement mode that runs entirely inside the cabinet, and a cloud-based real-time billing mode that synchronizes with the operator platform. When the network link is interrupted, the charger keeps authorizing sessions, keeps metering energy and keeps writing transaction records to local storage.

Key Advantages

• Dual billing architecture: local offline settlement and cloud real-time billing operate in parallel rather than as alternatives.
• Even when the network connection is interrupted, the charger still completes charging sessions and records fees normally, ensuring zero revenue loss for operators during outages.
• Local transaction records are stored on the controller and uploaded automatically once connectivity is restored, with no manual reconciliation step.
• Compatible with mainstream global payment gateways and electronic wallet systems, so one cabinet can serve several regional settlement schemes.
• Supports credit card, QR code payment and account deduction, giving end users a familiar payment experience without an attendant on site.
• Reduces on-site operating labor for station owners, since authorization, settlement and receipts are handled by the charger itself.
• Offline mode can run in a restricted whitelist mode for fleet cards when the operator prefers prepaid authorization.

• Public charging stations in areas with unstable connectivity
