Electric Vehicle GTR Test Development, Validation, and Assessment

A global technical regulation for electric vehicles (GTR No. 20) was established in the Global Registry on March 14, 2018. GTR No. 20 introduced performance-oriented requirements that address potential safety risks of electric vehicles while in use and after a crash event, including electrical shocks associated with the high-voltage circuits of electric vehicles and potential hazards associated with lithium-ion batteries and/or other rechargeable electric energy storage systems. To assess the requirements of GTR No. 20, NHTSA initiated an effort to develop a detailed laboratory test procedure and conduct the associated tests on a commercially available electric vehicle. A model year 2019 Chevrolet Bolt was chosen. This project only sought to cover the in-use requirements of the GTR’s sections 5.1, 5.3, and 5.4. This report outlines the draft test procedures that were developed for this project and the results of the in-use testing on the 2019 Chevrolet Bolt. Revised test procedures will be developed based on the findings of this project.
