TSE K 646

TSE K 646 is a criterion for competent services that work on road electric motor vehicles, defining how these service providers are classified and what general and special rules apply to maintenance, diagnosis, and repair operations. Electric-vehicle service work combines conventional mechanical servicing with high-voltage electrical and electronic expertise, so workshop organisation, staff competence, technical equipment, and structural features are all central to the service model.

Technical areas covered by the service scope

The scope brings together the main vehicle systems that may require maintenance and repair, including the engine, gearbox, drivetrain, suspension system, electrical and electronic systems, auxiliary systems, additional systems or modifications, and bodywork such as body and paint. In electric vehicles these areas are closely interconnected; for example, driveline behaviour and electronic control units often have to be assessed together during fault diagnosis, rather than as isolated subsystems.

General and special rules for authorised services

• General rules: management arrangements, employee characteristics, technical equipment, and structural requirements.
• Special rules: the practical principles for access to maintenance, diagnostic, and repair service locations and for delivering those services.
• The criterion addresses both the classification of service locations and the organisation of service delivery.
• It distinguishes between core vehicle systems and auxiliary or additional systems relevant to electric vehicles.

From a general technical perspective, electric-vehicle service centres need suitable high-voltage safety practices, accurate diagnostic tools, organised workspaces, and trained personnel. Standards of this kind are intended to align the service environment with the vehicle’s technology, not merely to describe repair work in the abstract. This record is also withdrawn, so it should be understood as a historical TSE criterion rather than a current active requirement.
