TSE K 646

TSE K 646 is a criterion for authorized service centers that maintain and repair electric road vehicles. It addresses how these services are classified and the general and specific rules for facilities that provide work on the engine, drivetrain, suspension, electrical and electronic systems, auxiliary systems, additional systems, and bodywork.

The standard is concerned not only with the technical tasks performed on the vehicle, but also with whether the service environment is suitable for carrying them out. Management practices, staff characteristics, technical equipment, structural features, and accessibility are all relevant to the orderly and safe delivery of electric vehicle service. Because electric vehicles involve high-voltage components, electronic control units, and software-dependent systems, the service infrastructure and personnel competence require a more specialized approach than conventional automotive servicing.

What the authorized service environment needs to support

• Organization of maintenance, diagnostics, and repair services
• Electrical and electronic systems plus auxiliary systems
• Drivetrain, suspension, and bodywork operations
• Treatment of modifications or additional systems within the service scope

In general technical terms, a standard like TSE K 646 helps distinguish between the vehicle systems that may be serviced and the facilities that are expected to support such work. Proper classification of electric vehicle service centers helps align equipment, workflow, and personnel knowledge with the demands of the service category. That makes the document a practical reference for structured, technically appropriate, and auditable service delivery.
