Precision Billing Begins Here: Londian’s CE Compliant EV Charger Metering Solutions for a Sustainable Future

The global transition to electric mobility is accelerating at an unprecedented pace. As electric vehicles shift from standard AC charging to high-performance DC fast charging, the infrastructure behind them must meet rigorous standards for safety, accuracy, and interoperability.

At the heart of every reliable charging station lies a high-quality energy meter. For Charge Point Operators (CPOs) and manufacturers, selecting a metering solution is no longer just about measuring electricity—it is about revenue certainty, legal compliance, and global market access. This is where Лондиан emerges as a critical partner, offering state-of-the-art EV Charger Metering solutions that are fully CE compliant.

Why CE Compliance is Non-Negotiable in EV Charging

In the European Economic Area (EEA), the CE marking acts as a product’s “passport.” It indicates that a product meets the essential requirements of relevant European Directives, particularly the Measuring Instruments Directive (2014/32/EU), commonly known as MID.

For EV charging, a CE-compliant meter signifies three specific things:

1. Accuracy: It guarantees that the kilowatt-hours (kWh) billed to the end-user match the actual energy delivered.

2. Legal for Trade: It allows CPOs to monetize public charging stations legally. Without an MID-certified (CE) meter, billing based on energy consumption is not permissible in many EU member states.

3. Reliability: It ensures the device can withstand electrical and environmental stresses (EMC, LVD).

Londian understands this landscape deeply. Our manufacturing processes are designed not just to meet, but to exceed these regulatory frameworks, ensuring that our clients face zero friction during market entry or grid integration audits.

Londian’s Technical Edge: Accuracy Class and Wide Range Measurement

One of the biggest technical hurdles in EV charging is the wide dynamic range of current. A meter must be as accurate when measuring a tiny trickle charge of 1A as it is for a hyper-fast 500A charge.

Londian’s latest generation of DC EV meters is engineered with high-fidelity analog-to-digital converters (ADCs) and low-temperature-drift shunts. This technology allows our meters to maintain accuracy class requirements as defined by IEC 62053-41 (specific to DC metering) across extreme load variations.

Key performance metrics of Londian CE-compliant meters include:

• High Precision: Achieving Class B or Class C accuracy, ensuring revenue-grade data.

• Temperature Compensation: Unlike standard meters that drift with heat, Londian meters integrate temperature sensors to maintain calibration in harsh outdoor environments.

• Bidirectional Measurement: Essential for V2G (Vehicle-to-Grid) applications, allowing energy to be measured both from grid-to-vehicle and vehicle-to-grid.

Hardware Versatility for Fast Charging Applications

Unlike AC home chargers, DC fast chargers bypass the vehicle’s onboard charger, delivering power directly to the battery. This requires the meter to handle high-voltage DC (up to 1000V) directly.

Londian offers robust hardware architectures designed for this rigorous environment. Our solutions support:

• Dual Ports: Allowing a single meter to service two charging guns independently, reducing BOM (Bill of Materials) costs for dual-outlet chargers.

• Integrated Shunts: Utilizing low-inductance shunts for high current measurement (up to 600A or more).

• Cable Loss Compensation: A sophisticated feature recognized in CE/MID certifications (such as those from PTB or NMi) that adjusts the measured energy to account for resistive losses in the charging cable, ensuring the customer pays only for the energy that enters their vehicle battery, not the heat lost in the wire.

Seamless Integration with Charging Networks

Compliance is not just about hardware; it is also about data integrity. Londian meters are equipped with robust communication protocols, primarily Modbus RTU over RS485 and Modbus TCP/IP.

Our CE-compliant meters support OCMF (Open Charging Metering Format), a standardized data format often required by German Eichrecht regulations. This allows the meter to produce cryptographically signed transaction logs. For a CPO, this means that if a customer disputes a charge, the operator can present a legally verifiable, tamper-proof record from a Londian meter.

The Londian “Factory” Advantage

Why do leading EVSE manufacturers choose Londian? It is our commitment to OEM excellence.

• End-of-Line (EOL) Calibration: Every single unit leaving our factory undergoes a 6-point calibration against traceable standards. We test every meter, not just samples.

• Customization: We understand that no two chargers are identical. Londian offers firmware whitelabeling, custom voltage inputs, and specific communication handshakes.

• Global Certifications: Beyond CE, our manufacturing lines support compliance with UKCA, UL, and other international standards, streamlining your global logistics.

Future-Proofing with Londian

As the EV market moves toward megawatt charging systems (MCS) for heavy-duty trucks, the demand for ultra-high accuracy DC metering will only grow. Londian is actively developing next-generation meters that combine ultra-high voltage capabilities with cyber-secure communication protocols.

Choosing Londian means partnering with a manufacturer that treats metrology as a core science. Whether you are deploying a public EV Charger Metering network or manufacturing the next generation of ultra-fast DC chargers, Londian provides the certified, accurate, and reliable metering infrastructure you need to power the future.
