Test & Calibration Equipment for CCS Charging Systems

You are looking for an approved solution to verify the functionality and calibration-law-compliant metering of DC fast charging stations?

We offer test equipment consisting of certified metering devices and approved controlled battery emulators for direct connection to CCS charging systems. The mobile system consisting of the certified measuring device EVM and the regulated battery emulator MLoad offers high performance in a compact and modular design. Together with a battery-supported auxiliary supply, it is ideal for mobile use in car cargo compartments.  Predefined test points can be individually selected and adjusted via the 7″ touch display. The communication according to DIN70121 and ISO15118 emulates real electric-vehicle charging behavior.

Combined, this equipment is officially approved as a measurement and calibration system by the German National Metrology Institute (PTB).

Requirements for Field Calibration

The correct billing of charging processes at DC charging stations and therefore the requirements for DC energy meters are becoming increasingly important.
To prove correct metering, test systems are needed that have to fulfill a number of requirements for this task:

  • Reference energy measurement must be 10 times more accurate than EVSE meters: Energy measurement with 0.2 % accuracy for currents from 10 A and voltages from 150 V

  • Measuring points must correspond to those in the type examination certificate: Specific calibration at defined load points necessary!

  • Charging stations need real charging behavior for trouble-free operation: Electronically controlled battery emulator needed. Purely resistive solution not sufficient!

Specifications & Variants

The modular design of the battery emulator allows flexible use depending on the requirements of the load points and the external conditions. This enables variable test systems adapted to different vehicle classes with appropriate dimensions and permissible total weight. Whether you need a compact solution for min/max calibration measurements or a mobile system that covers the entire power range of different charging stations, we offer the right systems across the entire application range.
