EV Charging in Commercial Buildings: Integrating OCPP & Loxone

As electric fleets and EV adoption rise, businesses need EV charging solutions that are efficient, scalable, and smart. Using a combination of Loxone + an OCPP integration will provide advanced control and billing features that support commercial EV infrastructure.

In this article, we’ll explore smart EV charging solutions for commercial properties and explain the advantages of integrating OCPP EV chargers with Loxone for commercial use.

What is OCPP & Why It Matters

The Open Charge Point Protocol (OCPP) is the global standard for communication between EV chargers and back-end systems. Designed to ensure interoperability and scalability, OCPP allows for secure, remote management of EV charging stations across different brands and models.

For commercial buildings, this means:

• Charging hardware isn’t locked to one software vendor

• Long-term cost savings by avoiding proprietary systems

• Remote monitoring, diagnostics, and firmware updates

• Real-time session tracking and billing integration

Loxone’s OCPP Server Connector supports both OCPP 1.6 and 2.0.1, allowing seamless communication between its smart automation system and compliant EV chargers. This forms the foundation for reliable, smart EV charging within a broader energy management ecosystem.

Why Loxone + OCPP Is Ideal for Commercial EV Charging

Pairing Loxone with OCPP brings commercial EV infrastructure into a smart, automated environment. Businesses benefit from:

✅ Billing Capability

Loxone tracks each charging session in real-time, assigns usage to authorised users via the NFC Code Touch, and generates clear reports. This is ideal for office buildings, apartment blocks, or mixed-use commercial properties with multiple EV users.

✅ Load Management

Electric vehicle charging can significantly increase a building's energy demand. Loxone automatically balances load to prevent electrical overload, ensuring safe distribution of available power across multiple chargers, especially during peak hours. It can also manage your solar and battery storage system to optimise EV charging during the best hours of energy generation, see below.

✅ Cost Optimisation

With smart scheduling and integration with dynamic energy tariffs, Loxone can defer charging to off-peak hours or when solar generation is highest. This ensures minimal energy cost and maximum use of renewable resources.

✅ Fleet & Multi-User Readiness

With NFC-based authentication and individual charging profiles, Loxone supports multiple users or fleet vehicles with ease. It tracks usage per vehicle or user, which is essential for accurate cost allocation and reporting.

Smart EV Charging Solutions for Commercial Properties

Here’s how to build a future-ready EV charging setup:

1. Choose an OCPP-Compatible Loxone Wallbox

Available in 7.4 kW and 11 kW variants with Tree or Air interfaces (their wired or wireless communication technologies), Loxone’s EV Wallboxes support advanced energy management, including integration with PV systems and home automation. Their sleek design and intelligent features make them suitable for both new builds and retrofits. 

2. Install Loxone Miniserver + OCPP Connector

The Miniserver acts as the brain of this automation setup. When connected to the OCPP Server Connector (create and managed inside the Loxone software), it can manage charging sessions, authenticate users, and coordinate charging with other systems such as lighting, heating, or solar power.

3. Add NFC Code Touch for Authentication

This wall-mounted device enables secure user identification with NFC cards. Ideal for workplaces or residential blocks, it logs who charged, when, and how much energy was consumed. Then bills them the specified rate at the correct rate using the pre-defined OCPP connector. 

4. Enable Smart Energy Management

When paired with PV systems, batteries, or dynamic tariffs, the system can prioritise self-consumption and use predictive control to charge when electricity is cheapest or greenest. Loxone also allows you to pause charging automatically during grid constraints.

Advantages of OCPP with Loxone Integration

• Accurate billing & transparency via energy meter data

• Dynamic load balancing prevents main fuse overloads if the premises energy consumption is in high demand, by reducing EV charging power temporarily

• Scalable fleet support with multiple chargers and user profiles

• Centralised control through the Loxone app and Miniserver

Frequently Asked Questions

• What is OCPP and why is it important?

  OCPP (Open Charge Point Protocol) is the open standard that ensures interoperability between EV chargers and central systems—supporting smart control and billing.

• Can Loxone integrate with OCPP EV chargers?

  Yes—the Loxone Miniserver supports OCPP 1.6 and 2.0.1, enabling secure communication, remote operation, and billing integration.

• What Wallbox models does Loxone support?

  Loxone supports OCPP-capable Wallboxes with Air and Tree interfaces, up to 11kW, offering scalable and efficient charging for fleets.

• How does user authentication work?

  Users can start charging using RFID/NFC cards via Loxone’s NFC Code Touch, which ties into OCPP for billing.

• Can charging be optimised based on energy prices?

  Absolutely—Loxone’s OCPP integration allows scheduling and charging during low-tariff times, or when renewable energy is available.

• Can different brands be installed?

  Yes. As long as the charger selected has an OCPP integration then you can use that. ZAPPI is a popular brand which can be installed with OCPP connection. Just ensure your EV’s OCPP compatibility is up to date as some do not support newer versions.
