Electrically propelled mopeds and motorcycles - Safety specifications - Part 2: Vehicle operational safety

This document specifies requirements for operational safety means and protection against failures related to hazards specific to any kind of electrically propelled mopeds and motorcycles when used in normal conditions. It is applicable only if the maximum working voltage of the on-board electrical circuit does not exceed 1 000 V alternating current (a.c.) or 1 500 V direct current (d.c.). This document does not provide comprehensive safety information for manufacturing, maintenance and repair personnel. This document does not consider specific aspects of driving automation features. NOTE For definition of the term “driving automation features”, see SAE J3016.

Overview

ISO 13063-2:2022 - Electrically propelled mopeds and motorcycles - Safety specifications - Part 2: Vehicle operational safety - defines operational safety requirements for electrically propelled mopeds and motorcycles (EV two-wheelers). It applies when the on‑board electrical circuit maximum working voltage does not exceed 1 000 V AC or 1 500 V DC. The standard focuses on in-use hazards and protection against failures in normal operating conditions; it does not replace safety guidance for manufacturing, maintenance or repair personnel and excludes specific driving automation features.

Key topics and technical requirements

• Operational safety management
  • Measures to mitigate credible single‑point failures (e.g., normally open/closed switches).
• Driving-enabled / disable mode
  • Movement by propulsion is permitted only in a driving‑enabled mode.
  • At least two deliberate and distinctive actions are required to switch from shut‑off to driving‑enabled; a single action suffices to disable.
  • Riders must be informed when propulsion is driving‑enabled.
• Partial driving and degraded power
  • Recommendations to indicate automatic reductions in propulsion power.
  • Low state of charge (SOC) must be indicated; minimum drive‑out capability and lighting reserve requirements apply where relevant.
• Reverse motion safety
  • Prevent unintended switching into reverse; either two actions required or a safety device that allows reverse only at low speed or when stationary.
• Parking and charging
  • The vehicle must indicate whether propulsion remains enabled when parked.
  • Vehicle movement must be disabled when a vehicle power supply circuit is physically connected to external power (cases A/B/C per IEC 61851‑1).
• Electromagnetic compatibility (EMC)
  • Functions that affect safe operation must tolerate normal electromagnetic environments; testing per ISO 11451 series.
• Emergency response and documentation
  • Manufacturers must provide crash/accident guidance for first responders (see ISO 17840, SAE J2578/J2990 references).
• Environmental conditions
  • Requirements apply across the range the vehicle is designed for; see ISO 16750 series for guidance.

Applications

ISO 13063-2 is used to:

• Guide EV two‑wheeler design for rider safety and fail‑safe operation.
• Define functional requirements for human‑machine interfaces (throttles, indicators).
• Inform compliance testing and vehicle validation during development.
• Support safety documentation for emergency responders and owner manuals.

Who should use this standard

• Motorcycle and moped manufacturers and design engineers
• Safety and compliance teams testing EV two‑wheelers
• Regulatory bodies and certification bodies assessing operational safety
• Component and system suppliers (controls, chargers, RESS integrators)

Related standards

• ISO 13063‑1 (RESS) and ISO 13063‑3 (Electrical safety)
• ISO 6469‑2, ISO 11451 (EMC), ISO 17840, IEC 61851‑1, ISO 16750

Keywords: ISO 13063-2, electrically propelled mopeds and motorcycles, vehicle operational safety, EV safety, RESS, driving-enabled mode, EMC, charging safety, emergency response.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 38,
Motorcycles and mopeds.
This first edition of ISO 13063-2, together with ISO 13063-1 and ISO 13063-3, cancels and replaces
ISO 13063: 2012, which has been technically revised.
The main changes are as follows:
— splitting the document into three documents which consist of the following parts, under the general
title Electrically propelled mopeds and motorcycles — Safety specifications:
— Part 1: On-board rechargeable energy storage system (RESS);
— Part 2: Vehicle operational safety;
— Part 3: Electrical safety;
— improvement of the operational safety requirements for the driving-enabled mode;
— addition of the requirement for vehicles with a permanently connected recharge cable according to
case A of IEC 61851-1;
— alignment with ISO 6469-2.
A list of all parts in the ISO 13063 series can be found on the ISO website.
