The test procedures are applicable to all components of the RESS and ancillary vehicle systems associated with electric propulsion; these standards can also serve as a guide for future designs. RESS safety performance is assessed with both single and dual point failure modes during all normal and abnormal operating conditions including charging, vehicle storage, operation, crash event, and post-crash state. Test data are used to quantitatively determine the response of the RESS at both the cell and system level.79
