Proposal for a new UN Regulation establishing uniform provisions for type approval of Electric Powertrain Retrofit Systems (EPRS) designed for conversion of vehicles of categories M and N to full electric propulsion. The regulation does not apply to vehicles holding approval under UN R155 or UN R156. It sets out requirements for EPRS manufacturers, installers, markings, approval procedures, general and specific technical requirements for retrofit systems, installer authorization and training, documentation to be provided by manufacturers, conformity of production, modification and extension of approvals, and penalties for non-conformity.

This regulation proposes uniform provisions for the approval of electric powertrain retrofit systems (EPRS) intended for the conversion of vehicles of categories M and N to electric propulsion. It establishes requirements for EPRS design, installation by authorized installers, type approval procedures, application ranges, markings, conformity of production, and modification or extension of approvals. Specific requirements for compliance with applicable UN Regulations are defined, including electromagnetic compatibility, braking, power measurement, rechargeable energy storage systems, and mass and dimension limits. The regulation applies to both pure electric vehicles (EV) and hydrogen fuel cell vehicles (HFCV).
