Scope

This document specifies the requirements for electric drive systems and components with a maximum operating voltage of class B voltage. This document describes potential environmental stresses, tests and recommendations for different levels of stress on or in a vehicle. This document includes general provisions such as definitions, installation locations, operating modes, etc. This document applies to electric drive systems and components whose maximum operating voltage is Class B voltage; this document does not apply to high-voltage battery packs (such as power battery packs) and systems or internal components. Like all other parts of GB/T 42284, this document does not apply to the environmental requirements or tests of the following parts: --- Harnesses, cables and electrical connectors; --- Parts or components inside the equipment (unless otherwise specified): - System integration of equipment and system verification on the vehicle (if no other test requirements are specified).
