Enterprise-Grade EV Charging Software Development with In-House EV Lab for Real Integration Testing – OCPP/OCPI/E-MSP

EV Charging Software Development Built for Technical Teams — Backed by an In-House EV Lab

Building a serious EV charging business is not just about launching an app and installing chargers. Behind every reliable charging experience sits a complex software stack: protocol gateways, real-time communication, billing engines, identity, security, analytics and regulatory reporting.

At Agmo Group, we help CPOs, car manufacturers and distributors in Malaysia and the region design, build and operate that stack — from OCPP/OCPI integrations to payment and analytics — with a strong focus on technical correctness, observability and scalability.

What sets us apart is that we are the only software powerhouse in Malaysia with an in-house EV lab, allowing real integration testing with various AC chargers from China/US/Europe before deployment. Your team doesn’t have to debug purely in production — we can reproduce and validate OCPP and payment flows in a controlled environment with physical hardware.

Below is a snapshot of what we’ve delivered in production with leading players in the market.

1. In-House EV Lab for Real-World Integration Testing

To reduce integration risk and speed up rollout, we operate a dedicated EV lab inside Agmo Group:

  • Multi-Charger Environment
    • Integration and regression testing across different charger OEMs and models
    • OCPP 1.6 and 2.x profiles validated against real hardware
    • Edge case scenarios: unstable connectivity, mid-session faults, firmware upgrades, etc.
  • Protocol & Backend Validation
    • Full round-trip testing of OCPP flows (authorize, start, stop, heartbeat, meter values, diagnostics)
    • OCPI and server-to-server scenarios tested against partner sandboxes and real chargers
    • OCPP/OCPI logs correlated with backend logs for easier troubleshooting
  • Payment & User Journey Simulation
    • Wallet, card, RFID and terminal payment flows run end-to-end in the lab
    • Auto Charge and Plug & Charge scenarios validated before going live
  • Faster Interoperability Debugging
    • Ability to reproduce bugs that your team sees in the field
    • Controlled experiments on configuration changes, firmware versions and charger vendors

2. CSMS for a Leading CPO in Malaysia

For one of Malaysia’s leading charge point operators, we implemented a full Charging Station Management System (CSMS) designed for high availability, protocol extensibility and operator efficiency.

2.1 Charging Point & Session Management

We designed and built:

  • Charging Point & Remote Management Module
    • Real-time monitoring of charger status (available, occupied, faulted, etc.)
    • Remote commands (start/stop, reset, configuration updates, firmware upgrade hooks)
    • Device lifecycle management and grouping
  • Session Module
    • Real-time session creation, updates and termination
    • Robust state machine for edge cases (connector errors, mid-session disconnects)
    • Session rating logic to feed into billing and analytics
  • Two-Wheeler Charging Support
    • Customizable session rules and constraints for two-wheelers
    • Flexible configuration for different connector types and tariffs

2.2 Organization, Roles & Security

Because this CPO works with multiple partners and operators, we delivered:

  • Organization and Operator Module
    • Hierarchical structure for organizations, operators and sites
    • Delegated administration and operator-level permissions
  • RBAC User Module & Audit Logging
    • Role-based access control across admin, operator, support and finance roles
    • Audit logging for critical actions (tariff changes, refunds, remote commands, etc.)
    • Traceability for security and compliance reviews

2.3 OCPP / OCPI Integration & Logging

Interoperability and debugging are crucial for any serious operation. Our implementation includes:

  • OCPP 1.6 & 2.x Server
    • WebSocket-based communication with charging stations
    • Modular handler structure for core, firmware, diagnostics and smart charging profiles
    • Extensible to support vendor-specific features
  • OCPI Integration
    • OCPI endpoints to expose locations, tariffs, tokens and sessions
    • Server-to-server communication with roaming partners and eMSPs
  • OCPP and OCPI Logs
    • Centralized structured logging of all protocol messages
    • Correlation IDs to trace a full flow (token → session → CDR → payment)
    • Log search to speed up incident investigation and interoperability testing

The EV lab plays a key role here: we capture and analyze protocol logs from real chargers to fine-tune handlers and improve resilience.

2.4 Dynamic Load Balancing & Smart Operations

To optimize energy usage and grid impact, we implemented:

  • Dynamic Load Balancing
    • Execution of load profiles based on site capacity constraints
    • Rules supporting number of connectors, simultaneous sessions and priority levels
    • Designed to integrate with future EMS/DR (Energy Management / Demand Response)

2.5 Monetisation, Payment & Customer Experience

End-to-end commercial flows were covered with:

  • RFID Card Module
    • RFID registration and token management
    • Mapping between users, organizations and cards
    • Support for white-listing and black-listing
  • Payment Module
    • Wallet – in-app balance top-ups and usage
    • Credit Card – online card integration
    • Payment Terminal – on-site payment terminal support
    • RFID Billing – mapping RFID sessions to wallets/accounts
  • Subscription & Prepaid Plans
    • Recurring subscription plans (e.g. monthly packages)
    • One-off prepaid plans with quota or kWh/time limits
  • Discount Code & Credit Voucher Module
    • Campaign-based discount codes
    • Vouchers and credits for marketing and customer support purposes
  • Auto Charge & Plug & Charge
    • Auto-start sessions for eligible users / vehicles
    • Reduced user friction for frequent chargers
  • Analytics Dashboard
    • Operational KPIs: uptime, utilization, error rates
    • Financial KPIs: revenue per site, ARPU, plan performance
    • Cohort and behavioral insights to inform pricing and rollout
