TSE K 646

TSE K 646 is a criterion for authorized services that maintain and repair electric road vehicles, defining how such services are classified and how maintenance, diagnosis, and repair activities should be organized under general and special rules. It addresses not only the vehicles themselves, but also the service organization: management, staff characteristics, technical equipment, and building-related conditions.

Service structure and scope of work

The standard focuses on authorized workshops serving road electric motor vehicles. Its scope mentions engine, gearbox, drivetrain, suspension, electrical and electronic systems, auxiliary systems, additional systems or modifications, and bodywork, including body and paint. That mix shows why electric-vehicle servicing is multidisciplinary: conventional mechanical assemblies, power electronics, control software, and high-voltage systems can all affect diagnosis and repair decisions.

General technical context

In general technical terms, rules of this type usually emphasize orderly workflow, personnel competence, suitable technical equipment, and physical facilities that support the service process. For electric vehicles, maintenance is not limited to fixing a visible fault; it often requires understanding how interconnected subsystems interact and how diagnostics translate sensor data, control logic, and mechanical condition into a repair decision. As a result, workshop layout, measurement tools, and diagnostic capability are especially important.

This TSE K 646 record represents a withdrawn standard, but its subject still provides a clear technical framework for understanding the service areas and organizational requirements associated with authorized electric-vehicle workshops.
