This part of the IEC62485 applies to secondary batteries and battery installations used for electric vehicles, e.g. in electric industrial trucks (including lift trucks, tow trucks, cleaning machines, automatic guided vehicles), in battery powered locomotives, in electric vehicles (e.g. goods vehicles, golf carts, bicycles, wheelchairs), and does not cover the design of such vehicles. This International Standard covers lead dioxide-lead (lead-acid), nickel oxide-cadmium, nickel-oxide-metal hydride and other alkaline secondary batteries. Safety aspects of secondary lithium batteries in such applications will be covered in their own appropriate standards. The nominal voltages are limited to 1000V a.c. and 1500V d.c. respectively and the principal measures for protection against hazards generally from electricity, gas emission and electrolyte are described. It provides requirements on safety aspects associated with the installation, use, inspection, maintenance and disposal of batteries.
