Scope

This document specifies the testing and acceptance of the safety performance of nickel-metal
hydride (Ni-MH) cells and modules used for electric road vehicles (EV). Electric road vehicles
(EV) include battery electric vehicles (BEV) and hybrid electric vehicles (HEV).
This document does not apply to the safety assessment of nickel-metal hydride (Ni-MH) cells
during transportation and storage.
NOTE 1: in this document, nickel-metal hydride (Ni-MH) secondary cells refer to sealed metal
hydride nickel cells: these sealed cells use nickel hydroxide as the positive electrode and
hydrogen alloy as the negative electrode, and alkaline aqueous solution, for example,
potassium hydroxide, as the electrolyte. Sealed cells are cells that can maintain their
sealed condition and will not release gas or liquid when charged and discharged within
the temperature range specified by the cell manufacturer. These cells are equipped with
a gas release device to prevent explosion.
NOTE 2: this document is to ensure the basic safety performance of the battery system under
expected use and reasonably foreseeable misuse during the normal operation of electric
road vehicles.
NOTE 3: in this document, all descriptions of cells are applicable to module testing.
