EV CHARGING APPS

Mobile Apps für EV-Laden

Mobile Apps für Betreiber von EV-Ladenetzen

Wir entwickeln mobile Anwendungen für EV-Ladenetze — Fahrer-Apps zum Auffinden, Reservieren und Bezahlen an Ladestationen, Apps für Betreiber und Techniker im Feld, plus OCPP-konforme Backends, dynamisches Pricing, eRoaming-Integrationen (Hubject, Gireve) und die Analytics dahinter. Für Charge Point Operators (CPOs) und E-Mobility-Service-Provider.

✦ EV CHARGING MOBILE APPS

Mobile applications for EV charging networks and operators

We don't sell chargers — we build the mobile applications that make EV charging networks work as a business. Driver apps, operator and field-technician apps, OCPP-native backends, billing, eRoaming and analytics, designed for operators who run real public or private charging infrastructure.

We deliver iOS and Android apps for drivers, an operator control panel and a field-technician app, plus an OCPP 1.6 / 2.0.1 backend that talks directly to the chargers — with session orchestration, dynamic pricing, eRoaming (Hubject, Gireve), invoicing and analytics that surface kWh, revenue and utilisation in a single dashboard.

✦ PAIN POINTS

Probleme, die wir in dieser Branche lösen

Charger unavailability

Drivers arrive at a station and find it offline, occupied or incompatible. Without realtime status they leave — and never come back.

Payment friction

RFID-only or proprietary apps create dead ends. Apple Pay / Google Pay + Plug-and-Charge is now table stakes.

Roaming chaos

Without proper Hubject/Gireve integration, your network is invisible to 70% of European EV drivers.

Zero operational insight

Static spreadsheets don't tell you which chargers underperform, which drivers churn, which sessions fail.

✦ KERN-FÄHIGKEITEN

Kern-Fähigkeiten der App

Live charger map with realtime status

Available / Occupied / Out of Service / Reserved — updated via OCPP StatusNotification with sub-second latency.

Start by QR or NFC

QR-code initiation with EVSE-ID auto-detection, NFC tap for Plug-and-Charge ISO 15118 sessions.

Wallet & multi-payment

Apple Pay, Google Pay, stored cards, prepaid wallet top-ups, RFID fallback — all reconciled to one driver account.

Reservations & scheduling

Reserve a charger 15–60 min ahead, fleet-grade bookings with cancellation policy, dynamic charger holds.

Live session telemetry

Realtime kWh, SoC%, charging power, estimated finish time pushed from the EVSE through OCPP MeterValues.

Receipts & invoicing

Per-session tax-compliant receipts, monthly statements, fleet invoicing with cost-center allocation.

✦ REALTIME

Echtzeit-Funktionen

OCPP 1.6J / 2.0.1 over WebSocket

Persistent secure WebSocket connections to every charger, with reconnect logic, heartbeat monitoring and command dispatch.

MQTT bridge for partner networks

Where OEM chargers use proprietary MQTT, we translate to OCPP transparently in the backend.

Push: charging started, finished, fault

FCM/APNs alerts to the driver and ops team, plus SMS fallback for ops if a charger goes offline mid-session.

Webhooks for fleet ops

Per-fleet webhook subscriptions for session lifecycle, useful for ERP/accounting integration.

✦ BACKEND-SYSTEME

Backend-Services, die wir bauen

OCPP gateway

Self-hosted CSMS (FastAPI + WebSocket), or commercial integration (Driivz, Etrel, Last Mile Solutions, ChargeLab) — your call.

Session orchestrator

State-machine that reconciles charger events with driver intent, computes pricing in realtime, finalises the transaction at StopTransaction.

Dynamic pricing engine

Time-of-use, kWh-based, idle-fee, fleet-tariff and ad-hoc — all expressed declaratively, audit-logged on every change.

Session & CDR store

PostgreSQL for sessions and Charge Detail Records (CDRs), with OCPI 2.2.1-compliant export.

✦ API INTEGRATIONS

API-Integrationen

OCPP 1.6J / 2.0.1
Charge Point Management System protocol — full BootNotification → StartTransaction → MeterValues → StopTransaction flow.
OCPI 2.2.1
Open Charge Point Interface for roaming with other CPOs and EMSPs.
Hubject / Gireve / e-clearing.net
eRoaming hubs — your network becomes visible across all major European MSPs.
ISO 15118 Plug & Charge
Cryptographic vehicle-to-charger handshake — no app, no card, just plug in.
Stripe / Adyen / Mollie
Driver wallet top-ups, recurring billing for fleet contracts, multi-currency support.
Mapbox / Google Maps
Map tiles with custom EVSE markers, routing with charger waypoints, isochrones.
SECURITY

Sicherheitsmodell

  • TLS 1.3 with mutual auth on every OCPP WebSocket
  • Per-tenant row-level security on session & CDR tables
  • PCI-DSS-aligned payment flow (no card data on our infrastructure)
  • ISO 15118 PKI for Plug-and-Charge certificate management
  • GDPR-compliant data retention with driver-initiated erasure
  • Penetration testing annually + after every major OCPP upgrade
SCALABILITY

Gebaut, um zu skalieren

  • Stateless OCPP gateway nodes — horizontally scaled with sticky sessions per charger
  • Per-charger event sourcing — every state change is replayable for audit and debugging
  • Read-only replica for analytics — separate from the transactional path
  • Multi-region deployment with data-residency partitioning (EU/UK/CH)
  • Geo-replicated CDR storage with 10-year retention for tax/audit compliance
  • Backpressure-aware WebSocket pool — graceful degradation under spike load
✦ IDEALE EINSATZGEBIETE

Ideale Geschäftliche Einsatzgebiete

Charge Point Operators (CPOs), E-Mobility-Service-Provider (EMSPs), EV-Flottenbetreiber, Hotels und Einzelhändler mit Ladestationen und EV-Hersteller.
