Smart Charging with Xemex – The Technology Behind Your Charging Station
The world of electric mobility is accelerating. Every day, more households and businesses install a charging station at home or at work. But behind the convenience of a simple plug-in lies a complex mix of measurement, communication, and optimization technologies. Xemex stands at the heart of this evolution, offering innovative solutions that make every smart charger more reliable, more efficient, and future-proof.
How Does a Charging Station Work Technically?
A charging station converts alternating current (AC) from the grid into direct current (DC) and delivers it to your electric vehicle’s battery in a controlled way. The internal controller, or EVSE (Electric Vehicle Supply Equipment), determines how much current can safely flow at any given moment.
A 1-phase charging station typically provides up to 3.7 kW, while a 3-phase charging station can reach 22 kW—ideal for faster charging at home or at the office. The charging station continuously monitors grid capacity, household load, and even electricity price signals to determine the optimal charging rate.
The main challenge? Lack of visibility and control.
When your heat pump, washing machine, and home charging station all operate simultaneously, the main fuse may trip. Many vehicles also charge during expensive peak hours. That’s where Xemex comes in—bridging the gap between raw data and smart energy control.
The Challenge: Insight, Balance, and Optimization
A smart charging station is only truly smart when it considers total household energy consumption. Many users notice that:
- Their charging station doesn’t communicate with other devices.
- They lack insight into total energy use.
- Dynamic tariffs aren’t being used.
- Solar (PV) energy isn’t optimally utilized.
Without an integrated Energy Management System (EMS), you may end up charging when energy is scarce or expensive. Xemex changes that equation.
Xemex Technology Behind Every Smart Charging Station
P1MB – The Bridge Between Smart Meter and Charging Station
The P1MB is a compact yet powerful interface that connects your smart meter with the charging station. It reads real-time data from the P1 port and translates it into Modbus communication, allowing the charger to automatically adapt to household energy consumption.
For installers, the P1MB is an efficient, plug-and-play solution—ideal for load balancing between EV charging and domestic use, even up to 100 m from the meter.
It’s tested with Fluvius smart meters (DSMR 4.0+) and compatible with multiple EMS setups, ensuring that your home charging station or Alfen charger always performs optimally.
SCC – Smart Charge Controller
The SCC (Smart Charge Controller) is the intelligent brain of your charging setup. It regulates power distribution between multiple charging stations or between chargers and household devices.
Imagine two EVs charging simultaneously—one on a Peblar charger, the other on an Alfen charger. The SCC automatically allocates available current, preventing overload and maximizing efficiency.
It communicates with the smart meter via Modbus, dynamically adjusting charging speed based on energy availability or PV generation. You charge faster when the sun shines, and slower when household demand peaks.
Smart Connect – Always Connected, Always Insightful
The Smart Connect P1 Dongle is a compact device that makes real-time consumption data available via Modbus TCP or MQTT. It acts as a digital bridge between your smart meter and connected systems such as EV chargers or Energy Management Systems.
What makes the Smart Connect unique:
- True EU quality, designed and produced in the Netherlands.
- Flexible installation via Ethernet, Wi-Fi, or direct peer-to-peer link with a charging station.
- Simple configuration through a built-in web interface (mDNS, IP, or hotspot).
- Continuous data reading every second (DSMR 5.0).
It also features a splitter function: the P1 output mirrors the input data, allowing you to connect one smart meter to multiple devices—such as an Alfen charging station for load balancing and a monitoring dashboard at the same time.
The LED indicator on the front instantly shows connection status (red, orange, or green).
Through integration with the ENNY Cloud Platform, the Smart Connect can send data to the cloud via an embedded MQTT broker—providing central monitoring without extra hardware.
LEWIZ Gateway – The Smart Measurement and Control Hub
The LEWIZ Gateway acts as the central data hub of modern energy systems. Rather than directly controlling charging plazas, LEWIZ aggregates readings from various sources—smart meters, solar inverters, heat pumps, and kWh meters—into one unified system.
It supports Modbus RTU, M-Bus, Smart Grid Ready (SGR), and LTE-M or Ethernet communication. Together with the KWHIQ (for precision metering) and SCC (for load balancing between charging stations), it forms the backbone of a truly intelligent charging ecosystem.
All data is sent to the ENNY Cloud Platform, giving users deep insight into energy consumption, PV production, and charging patterns. The LEWIZ doesn’t manage an entire charging plaza directly—it’s the integrator that brings all Xemex components together in one real-time overview.
The Heart of the System: ENNY Cloud Platform and ENNY App
All Xemex solutions integrate into the ENNY Cloud Platform, where raw metering data is transformed into actionable insights. You can see not only how much you charge, but also when it’s most cost-effective to do so.
The ENNY App translates this into a user-friendly interface, showing:
- Real-time charging status
- Cost per session
- Total energy balance
- PV generation
- Grid feed-in or self-consumption
For professionals, the platform offers extensive dashboards with tools for fleet management, energy monitoring, and trend analysis.

From Raw Data to Smart Control
The example below describes a hypothetical situation that demonstrates how a Xemex solution can work in practice.
A technical services company in Antwerp wants better insight into the energy flows within its building.
It has a Peblar charging station, solar panels, and a heat pump—but lacks a central overview.
After installing a LEWIZ, KWHIQ, and SCC, all components are connected. The KWHIQ measures the exact consumption of the charging station, the SCC manages load balancing, and the LEWIZ collects and visualizes all data in the ENNY Cloud Platform.
The result is a single, comprehensive overview of consumption, production, and charging behavior. The system automatically coordinates EV charging with solar generation and grid capacity—not by directly controlling charging plazas, but through smart data integration and centralized monitoring.
That’s what Xemex does best.

A charging station is more than a plug for your car—it’s a crucial element of your smart energy network.
With P1MB, Smart Connect P1, SCC, LEWIZ, and KWHIQ, Xemex provides a full ecosystem for communication, control, and optimization.
Through the ENNY Cloud Platform and ENNY App, you gain total control over your home charging station or business setup—insight, balance, and optimization in one integrated environment.
Whether you manage a single 3-phase home charger or an entire EV fleet with Alfen and Peblar chargers, Xemex ensures your system stays smart, stable, and ready for the future.
