Mobile solutions for on-site testing of EV charging stations

With the help of ZERA’s modern measurement technology, you can test your charging station! We offer testing solutions for the metrological testing of charging stations on-site – testing for the correctness of the measurement accuracy. These are tests that have to take place repeately, e.g. when the calibration period of the charging station has to be extended or maintenance has been carried out on the charging station.

Stationary solutions for testing EV charging stations

Beyond the portable EMOB test cases we offer stationary systems for testing AC charging stations and testing DC charging stations (high power charger) for manufacturer or provider of charging stations. These special test systems can be used within the scope of the quality assurance or for calibration in order to guarantee a high accuracy of the charging station.

Advantages of a ZERA EMOB test case:

  • There is no comparable device on the European market (as of October 2023)
  • High accuracy of 0.1 % in related to power
  • ZERA is the first manufacturer on the European market to offer a combined test device for AC and DC charging stations
  • Our devices have the highest possible safety features, from mechanical interlocking to high-current monitoring (see list for details)
  • Combination of test case and "stand-alone" test device makes the test solutions for e-mobility modular and customised
  • Automatic control of the test case via WiFi
  • Guided test procedure via a tablet = step-by-step instructions
  • Independent of the power supply thanks to its own battery
  • The connected Reference Meter is non-sensitive to interference frequencies up to 150 kHz (important in the surroundings of charging parks)

Test case  & test device in one unit

The stand-alone Reference meter from the s2 series (MT310s2 or MT320s2) serves as the test device and can either be operated independently of the EMOB test case or used with any test case from the EMOB series. The test case forms the interface between the charging station and the test meter and guarantees safe handling.

Safety features - all cases have maximum safety features:

Inspection of the correct contacting of the connected cables

  • Detection of the charging cable type
  • Electromechanical plug locking of the connections

All test cases for DC currents (EMOB200-00, -10, EMOB500):

  • Overcurrent detection of the DC high-current pins

EMOB80, EMOB200-00 and -10 and EMOB500:

  • Temperature monitoring of the AC contacts and the DC high-current contacts. As soon as the predefined temperature is reached, the charging process is automatically switched off. It can only be switched on again once it has cooled down sufficiently.

Making installations functional and available in the long term

Our accessories can be used to carry out on-site measurements of your charging station for electric vehicles. You do not need any mains supply for the application or testing of e-charging stations, so our measurement solution can be used flexibly. With the help of our test systems, you can test charging stations precisely. You receive the measured values simply at a glance and can thus quickly detect inaccuracies and intervene if necessary. In addition, testing e-charging stations with the help of our products can support fault diagnosis. Keep the reliability of your equipment at a high level by using our reliable and accurate testing systems.

Checking charging columns – verifiable conformity with legal regulations

With ZERA’s modern technology, you can check charging stations, record their condition and thus ensure safety. E-charging stations also have legally defined requirements that must be met. Technical requirements are laid down in the charging station ordinance and DGUV and must be kept up to date in accordance with the law. A testing system can help you to fulfil the testing obligation and thus ensure compliance with legal requirements. With the technical solutions from ZERA, you can test charging columns and operate charging systems in compliance with legal regulations.
