T/ZJSAE 021-2024 The safety inspection specifications for new energy commercial vehicles

Scope

Scope: This document specifies the terms and definitions, inspection items, inspection conditions, and inspection methods for the safety inspection of in-use new energy commercial vehicles. This document applies to the safety inspection of in-use new energy commercial vehicles, including pure electric, plug-in hybrid, and fuel cell commercial vehicles. Main technical content: 1. Main inspection items: Reference to some test items of traditional safety inspection items in GB 38900-2020 "Technical Inspection Items and Methods for Motor Vehicles". New energy safety inspection items include: consistency check of electric vehicle core components, vehicle electrical safety, vehicle control, battery safety, and charging function inspection. The test is conducted from three aspects: functional testing, performance testing, and safety testing. 2. Inspection process: Divided into static inspection and dynamic inspection according to the inspection state; the inspection process planning classifies the equipment, workstations, and test conditions required for the test and formulates the inspection process according to the principle of optimal efficiency. 3. Inspection methods: According to the different inspection items, the inspection methods are divided into manual static visual inspection, static safety electrical inspection, static functional electrical inspection, and charging inspection, etc. 4. Inspection requirements: Technical requirements are formulated for vehicle appearance, safety devices, vehicle uniqueness, consistency of electric vehicle core components, vehicle electrical safety (interface insulation, vehicle insulation, insulation resistance monitoring, etc.), vehicle control, battery safety, and charging function verification, etc.
