Im Jahr 2015 stieg die Beliebtheit von selbst-stabilisierenden Rollern (besser bekannt als „Hoverboards“) sprunghaft an. Leider kam es schon bald zu ernsthaften Sicherheitsproblemen, da es beim täglichen Gebrauch und beim Aufladen zu Brandentwicklungen kam. In dem zuletzt von UL veröffentlichten White Paper „UL 2272 and The Safety of Personal e-Mobility Devices“ werden diese Probleme und die Reaktion des Marktes analysiert sowie die Lösung von UL betrachtet.

In addition to these fires damaging the hoverboards themselves, every incident risked rider/user injury or property damage (over $2 million of property damage were reported in less than three months). Building on more than a century of expertise in safety and over two decades spent with EV electrical systems, UL 2272 was developed. According to the whitepaper, “In contrast to standards that are applicable only to lithium-ion batteries, ANSI/CAN/UL 2272 takes a system-wide approach to the electrical safety of e-Mobility devices that incorporate drive systems using rechargeable lithium-ion batteries.”

The comprehensive evaluation under UL 2272 includes electrical, mechanical, environmental, and material and component testing as well as marking and instruction requirements. Though safety testing for individual hoverboard components, including lithium-ion battery cells and packs, chargers and power supplies, has been available for several years and is important, a system-wide approach is necessary and UL 2272 delivers just that. In fact, though ANSI/CAN/UL 2272 is voluntary, the U.S. Consumer Product Safety Commission (CPSC) considers scooters that have not met this standard to be defective and at risk of recall.
