UL 5840

These requirements cover the electrical system of lithium based battery powered airport ground support equipment (GSE) with respect to a risk of fire, electric shock, and explosion hazards associated with the battery powered electrical system.

These requirements also cover these electrical systems when they are used to convert fueled GSE to battery powered GSE.

In accordance with 1, the minimum GSE electrical system consists of the battery and integral battery management system, interconnecting cables, and input connections for recharging the battery. In addition, the electrical system can also include power train components, electric motors, electric brakes, charging equipment and the like based on manufacturer preference.

GSE that is capable of being moved and used as a temporary source of power for other equipment, whether that equipment is either located on board the GSE or off board the GSE, is additionally evaluated based on mobile energy storage systems requirements.

This standard does not address the functional or operations aspects of the GSE such as steering, lifting, towing, and the like.

This standard does not address any equipment or electrical systems of equipment that are not considered GSE as defined within this standard.

In relation to conversion systems, these requirements do not address the function or mechanical state of the GSE being converted, or the parts located external to the manufacturer’s defined electrical conversion system that may be powered from the electrical conversion system.
