## Abstract

This document responds to petitions for reconsideration of the Federal motor vehicle safety standard that addresses occupant crash safety issues exclusive to electric vehicles: electrolyte spillage and electrical shock protection. We are making clarifying amendments regarding the application of the standard, and regarding the test conditions for battery state of charge and electrical isolation. We are denying a petition to specify an alternative performance requirement for electrical isolation.
