Optional details for Sales or Support
For Sales

What would you like to test?

  1. Application: EV, EVSE, MCS, BMS, EMC, production or field
  2. DUT and direction: what is real, what must be simulated
  3. Standards and interfaces: required families, editions and connectors
  4. Electrical range: voltage, current, power and load or source concept
  5. Workflow: manual, automated, API, HiL, EOL or mobile use
  6. Project frame: location, schedule, integration and procurement route
For Support

Identify the system and the observed behaviour.

  1. System: product name, configuration and serial number
  2. Installed state: software, firmware and relevant library versions
  3. Test setup: DUT, interfaces, direction and connected equipment
  4. Observation: expected result compared with actual behaviour
  5. Evidence: logs, traces, screenshots, reports and reproduction steps
  6. Operational context: frequency, timing, urgency and safety relevance

Keep evidence attributable: retain the original file names, timestamps, system state and test configuration when sharing logs or reports.

Routing questions

Contact FAQ

Should an upgrade request go to Sales or Support?

Use Sales when the decision concerns a new option, hardware extension, additional interface, commercial scope or quotation. Use Support when the issue concerns the installed state, compatibility, operation or a technical case. Include the existing system configuration in either route.

Which contact should be used for calibration or maintenance?

Use Technical Support. Identify the product, configuration, serial number, location and required service. The published DAkkS accreditation scope and management-system evidence remain available under Quality & Certifications.

Can an international sales partner handle the request?

Use the Sales Partners page to identify published regional access. Product, territory and service responsibilities can differ, so the concrete route should be confirmed for the project.

What makes a technical support request actionable?

Include the system identity, software and firmware state, test configuration, expected and observed behaviour, reproduction steps and the available evidence. This enables the case to start from the technical state rather than from product identification.

Are the Sales and Support email routes also used for North America?

Yes. For international enquiries, contact Sales at or Technical Support at . You can also contact our North American office by telephone.

How are test results documented?

Tell us which result you need to document. We can identify the relevant product documentation and clarify which configurations, measurements, traces, evaluations or reports the selected workflow supports.
