Standard for Safety — Electrical Systems for Personal E-Mobility Devices
UL 2272 is a system-level safety standard for the complete electrical system of personal e-mobility devices including self-balancing scooters (hoverboards), stand-up electric scooters, and similar two-wheeled personal transport devices. It was introduced in response to widespread hoverboard fire incidents in 2015–2016 and addresses the battery pack, charger, motor controller, and wiring harness as an integrated system.

Scope
UL 2272 applies to self-propelled personal transportation devices with a maximum speed of 35 km/h, operated by a standing rider. It covers the complete electrical system safety including battery pack, charger, and drivetrain electronics. Certification to UL 2272 is required by many major retailers and is referenced in CPSC guidance for hoverboards sold in the United States.
Key Requirements
Battery and Charger Safety
The battery pack must pass overcharge, short circuit, mechanical abuse, and environmental tests. The charger must automatically terminate charging when the battery reaches full charge and must include protection against output overvoltage. The pack and charger together are tested as a system to identify compatibility issues.
System-Level Electrical Safety
Motor controller and wiring harness must meet insulation, routing, and connector requirements to prevent chafing damage and short circuits during use. Electrical tests verify that the drivetrain electronics cannot cause overcurrent conditions in the battery wiring. Fault simulation tests confirm the system shuts down safely under abnormal conditions.
