When purchasing an EV charger for charging electric vehicles, the integrated energy meter plays a crucial role.
It enables the measurement of electricity consumption and is essential for billing, monitoring, and meeting legal requirements. Learn about the different types of energy meters available-from no meter, to software-based solutions, to MID-certified and calibration-law-compliant meters-and find out which type of meter you need for your specific use case.
Different types of energy meters
1. EV charger without an energy meter
EV chargers without an energy meter are the simplest and most cost-effective option. They are suitable for private households where the total electricity consumption of the house, including the electric vehicle, is billed together. This solution is ideal if no detailed consumption analysis or separate billing is required.
Use cases:
Private use without billing requirements
Homeowners who only want to monitor total electricity consumption
2. EV charger with a software-based energy meter
Software-based meters record electricity consumption digitally. The data cannot be used for legally compliant billing but is useful for monitoring and optimization. Our DaheimLader Smart PRO displays the electricity consumption on the screen in a tamper-proof manner and transmits meter readings online to our Click2Charge app.
Use cases:
Private use with a focus on consumption monitoring
Users who want to optimize their charging sessions (e.g., PV surplus charging)
3. EV charger with an MID-compliant energy meter
MID meters comply with the European Measuring Instruments Directive and are certified, making them suitable for legally compliant billing—for example between employers and employees or landlords and tenants. The DaheimLader Touch PRO offers such an MID-certified energy meter, ideal for precise monitoring and analysis. With the purchase of a DaheimLader EV charger, you can use the billing system in our Click2Charge app free of charge.
Use cases:
Company car charging with employer reimbursement
Use of the EV charger by tenants
Semi-public areas such as company or customer parking lots
4. EV charger with a calibration-law-compliant energy meter
Calibration-law-compliant meters meet the strictest legal requirements and are necessary for public charging stations where the charging electricity is billed precisely per kWh. If you operate an EV charger in a commercial environment or want to bill charging electricity publicly, a calibration-law-compliant meter is mandatory. These meters provide maximum transparency and security for billing and must be professionally installed and regularly maintained.
Use cases:
Public charging stations (e.g., parking garages, hotel parking lots)
Areas with multiple users or vehicles

Conclusion
Choosing the right energy meter largely depends on the intended use case. While simple solutions without a meter or with software-based systems are sufficient for private households, MID-certified or calibration-law-compliant meters are essential for accurate billing in commercial or public environments.
With the Smart PRO and Touch PRO models, we offer flexible solutions for different requirements—from private monitoring to legally compliant billing. In our app, you can easily download the data analysis as a PDF or CSV file.
