OCPP CSMS Core
A WebSocket OCPP 1.6J / 2.0.1 back-end with robust message handling, a device registry and clean data models — the reliable heart of your charging station management system.
Consultancy · EV Charging Station Software
EV charging software that speaks OCPP 1.6J & 2.0.1
We design, build and integrate the EV charging station software behind a modern network — a CPMS / CSMS back-end speaking OCPP 1.6J & 2.0.1, with charge point management, smart charging & load management, RFID authorization, transactions & billing, OCPI roaming, hardened security, and operator dashboards with 24/7 monitoring. It's the same platform engineering behind our own production CPMS — a live OCPP network of AC & DC chargers with operator, host, fleet and driver portals, prepaid wallets and UPI payments.
Live CSMS view: OCPP sessions, network power, charge-point status & message log.

What We Deliver
A complete EV charging software stack — CPMS / CSMS, OCPP and everything around it
From the OCPP back-end to dashboards, billing and roaming, we deliver every layer a charge point operator needs to run a reliable, standards-based charging platform.
Charge Point Management
Charger onboarding and configuration, live heartbeats, faults and meter values, plus remote start-stop, reset, unlock and change-availability commands that reach the charger in about a second — with OTA firmware across the fleet.
Smart Charging & Load Mgmt
OCPP charging profiles, dynamic load balancing and power sharing across a site, and time-of-use tariffs so a shared grid connection is never exceeded.
Authorization & Billing
RFID / ID-token authorization, MeterValues metering and transactions, flexible tariffs and campaign discounts, prepaid driver wallets, UPI payments, promo codes, referrals and rewards, with automatic wallet settlement and invoicing.
Roaming & Integrations
OCPI roaming, eMSP and driver-app integration, payment gateways, and energy / DER and third-party APIs to connect your network to the wider e-mobility ecosystem.
Security, Portals & Monitoring
TLS/WSS, OCPP security profiles, ISO 15118 Plug & Charge, multi-tenant role-based access (super-admin to site staff), and separate operator, host, fleet and driver portals — with live dashboards, exportable reports, analytics and alerting for 24/7 operations.
Our Process
A complete, standards-based path from OCPP scope to a live charging platform
Seven engineered steps take your project from requirements and OCPP scope through architecture, smart charging, billing, security and a live, monitored deployment.
01
Step 01 · Requirements & OCPP Scope
Requirements & OCPP Scope
We map your charger models, target OCPP version (1.6J or 2.0.1), operator and driver use cases, scale and compliance needs into a clear, standards-based specification before a line of code is written.
- Charger models & connector types
- OCPP 1.6J / 2.0.1 & feature profiles
- Operator / driver use cases & scale
02
Step 02 · CSMS Architecture & OCPP Core
CSMS Architecture & OCPP Core
We design a scalable OCPP WebSocket (JSON) server with robust message handling for the core and smart-charging profiles, a device registry, a normalized database and clean REST APIs.
- OCPP WebSocket / JSON server
- Message handling & state machine
- Device registry, DB & APIs
03
Step 03 · Charge Point Management & Monitoring
Charge Point Management & Monitoring
We deliver charger onboarding and configuration, live heartbeats/faults/meter values, remote start-stop, reset, unlock and change-availability (commands land in about a second), live diagnostics and over-the-air firmware updates.
- Onboarding, config & live status
- Remote start / stop / reset / unlock (~1s)
- Diagnostics & OTA firmware
04
Step 04 · Smart Charging & Load Management
Smart Charging & Load Management
We implement OCPP charging profiles, dynamic load balancing and power sharing across a site so you stay within your sanctioned demand, and time-of-use tariffs so charging shifts to cheaper, greener windows.
- Charging profiles & scheduling
- Load balancing within sanctioned demand
- Time-of-use tariffs & grid limits
05
Step 05 · Authorization, Billing & Roaming
Authorization, Billing & Roaming
We build RFID / ID-token authorization, metering and transactions (MeterValues), flexible tariffs and campaign discounts, prepaid driver wallets and UPI payments, promo codes and referrals, automatic settlement and invoicing, plus OCPI roaming across partner networks.
- RFID / ID-token authorization
- Wallets, UPI, tariffs & invoicing
- Promo codes, referrals & OCPI roaming
06
Step 06 · Security, Compliance & Testing
Security, Compliance & Testing
We harden the platform with TLS/WSS, the OCPP 2.0.1 security profiles and certificate management, ISO 15118 Plug & Charge, RBAC, penetration testing and OCPP compliance testing.
- TLS/WSS & OCPP security profiles
- ISO 15118 Plug & Charge, certificates
- Penetration & OCPP compliance testing
07
Step 07 · Deployment, Dashboard & Operations
Deployment, Dashboard & Operations
We deploy to cloud or on-prem with role-based portals for operators/CPOs, site hosts, fleet managers and drivers, live monitoring, exportable session/energy/revenue reports, analytics and alerting — then support ongoing updates, tuning and scaling as your network grows.
- Cloud or on-prem, multi-tenant
- Operator, host, fleet & driver portals
- Exportable reports, monitoring & alerts

FAQ
EV charging software, CPMS & OCPP — your questions answered
Common questions about OCPP, CPMS / CSMS, smart charging, billing, roaming and security.
Yes. We build and integrate CSMS back-ends that speak OCPP 1.6J and OCPP 2.0.1 over secure WebSocket (JSON). We implement the core profile plus smart charging, firmware management, remote trigger, reservation and the OCPP 2.0.1 security profiles, and we can operate a mixed fleet where some chargers run 1.6J and others run 2.0.1 on the same CSMS platform.
A CPMS (Charge Point Management System), also called a CSMS (Charging Station Management System), is the cloud back-end that manages your chargers end to end: onboarding, configuration, boot/heartbeat/status, authorization, transactions, smart charging, billing, roaming and monitoring. We do both — build a CSMS from scratch, or integrate and extend an existing one with new OCPP features, REST APIs, dashboards, load management or OCPI roaming.
Yes. We implement OCPP charging profiles and scheduling, dynamic load balancing and power sharing across a site so a shared grid connection is never exceeded, and time-of-use tariffs so charging shifts to cheaper, greener windows — protecting the transformer while keeping vehicles ready on time.
Yes. We implement RFID / ID-token authorization (with local authorization lists and auth cache), MeterValues metering, StartTransaction/StopTransaction handling, flexible tariffs and invoicing, payment-gateway integration, and OCPI-based roaming so your drivers can charge across partner networks and eMSPs with clean settlement.
We secure the OCPP channel with TLS/WSS, implement the OCPP 2.0.1 security profiles with certificate management, support ISO 15118 Plug & Charge, enforce role-based access control (RBAC) and audit logging, and validate everything with penetration testing and OCPP compliance testing before go-live.
You receive a production OCPP 1.6J / 2.0.1 CSMS back-end, REST APIs and a documented data model, operator and driver dashboards, smart charging and load management, authorization, billing and OCPI roaming, security and compliance test results, monitoring, analytics and alerting, plus full documentation and handover.
