Example of set positions of heater and temperature sensor in Heating D. Principle for developing the global technical regulation 24. This gtr addresses the unique safety posed by EVs and their components, considering the following points: (a) To ensure a safety level equivalent to conventional vehicles with internal combustion engine and to prevent EV-specific hazardous events, assuming a reasonable level of the robustness; (b) To identify and assess the potential safety risks, depending on the relevant vehicle conditions such as: (i) in normal use, in active driving possible mode and parking; (ii) in normal use, during external charging/feeding; (iii) in an accident (during and post-crash). (c) To consider the safety validation of the entire battery system of the vehicle (e.g. BMS); (d) To be to the extent possible without disturbing future technology development; (e) To be reasonable, practicable and effective; (f) To develop and validate test procedures that are repeatable and reproducible, taking account for the difference of dimensions, configurations and materials (e.g. type of REESS) of the relevant EV on usage; (g) The safety during the external charging/feeding may not be ensured through the legal requirement on the vehicles. Therefore, the informal working group will aim to establish the overall safety of the vehicle and the external charging/feeding infrastructure in a comprehensive manner by showing the accountability of vehicles to the related stakeholders. 25. This gtr was developed to accommodate different types of vehicle certification processes. The following are examples of two primary systems used by Contracting Parties. 1. Self-Certification system in the United States of America 26. It is the responsibility of a manufacturer of vehicles and/or of motor vehicle equipment to certify that each motor vehicle and/or equipment item is in full compliance with the performance requirements of all applicable Federal Motor Vehicle Safety Standards (FMVSS). The FMVSS specify test methods and conditions that would be used to assess compliance of a vehicle or motor vehicle equipment to applicable FMVSS. However, manufacturers may use alternative methods to certify their vehicles. Manufacturers using alternative methods to certify their vehicles and equipment are responsible for ensuring that the vehicles and equipment would comply with the requirements of applicable FMVSS when evaluated by the methods specified in the FMVSS. 27. The manufacturer must not only be concerned with the initial certification, but should also monitor continued compliance of vehicles and/or items of motor vehicle
