UN Regulation No. 136 — Electric Power Train Safety for L-Category Vehicles
UN R136 sets type-approval requirements for electric power trains and rechargeable energy storage systems in specified L-category vehicles.

When it matters
Relevant when an electric motorcycle, moped, three-wheeler, or qualifying quadricycle needs type approval in a jurisdiction applying UN R136.
Key considerations
- Applies through vehicle type approval, not generic battery certification.
- Covers electric-shock and REESS safety.
- Controlled configurations and authority review are required.
Project preparation
- Confirm vehicle category, route, voltage, and regulation series.
- Define mounting, interfaces, isolation, protection logic, and warnings.
- Coordinate vehicle samples, documents, and prescribed testing.
