Variant Models for Electric Vehicle Charger Certification
The relevant requirements to include variant models in an Electric Vehicle Certificate are:
- Same hardware topology
- Same firmware and control version
- Nominal current of the variant model within the 50% and 100% of the nominal current of the tested unit
Any other scenario may include additional tests to include these variants in the certification.
