Standard for Safety for Batteries for Use In Electric Vehicles

1 Scope

1.1 These requirements cover electrical energy storage assemblies such as battery packs and combination battery pack-electrochemical capacitor assemblies and the subassembly/modules that make up these assemblies for use in electric-powered vehicles as defined in this Standard. This Standard also covers a battery management system  that provides protection and control for the EESA.

1.2 This Standard evaluates the electrical energy storage assembly’s ability to safely withstand simulated abuse conditions and prevents any exposure of persons to hazards as a result of the abuse. This Standard evaluates the electric energy storage assembly and modules based upon the manufacturer’s specified charge and discharge parameters at specified temperatures. It does not evaluate the assembly's interaction with other control systems within the vehicle.

1.3 This Standard does not evaluate the performance or reliability of these devices.

1.4 This Standard is divided into parts to address specific criteria for different types of vehicle applications. Part 1 of this Standard are general requirements that may apply to all vehicles as noted in the individual parts. The following is the organization of the vehicle specific parts of this Standard:

a) Part 2 – On road vehicles

b) Part 3 – Two and three wheeled on road vehicles (e.g. motorcycles)

c) Part 4 – Off road electric vehicles evaluated to UL 583 (e.g. industrial trucks)

d) Part 5 – Electric vehicles utilized for earth moving and similar applications (e.g. for agriculture, mining or construction)

1.5 Part 6 of this Standard applies to starter batteries.

1.6 This Standard does not include requirements for the evaluation of batteries for light electric vehicles such as electrical assist bicycles, wheel chairs, personal e-mobility devices and similar devices as defined in UL/ULC 2271.
