Electrically propelled mopeds and motorcycles - Safety specifications - Part 1: On-board rechargeable energy storage system (RESS)

This document specifies safety requirements for rechargeable energy storage systems (RESS) of electrically propelled mopeds and motorcycles for the protection of persons. It does not provide the comprehensive safety information for the manufacturing, maintenance and repair personnel. NOTE Additional safety requirements can apply for RESS that can be recharged by means different from supplying electric energy (e.g. redox flow battery).

Overview

ISO 13063-1:2022 - "Electrically propelled mopeds and motorcycles - Safety specifications - Part 1: On-board rechargeable energy storage system (RESS)" defines safety requirements for on-board rechargeable energy storage systems used in electric mopeds and motorcycles. The standard focuses on protection of persons (riders and bystanders) from electrical, chemical and thermal hazards arising from RESS. It is not a comprehensive occupational safety manual for manufacturing, maintenance or repair personnel.

Keywords: ISO 13063-1, RESS, rechargeable energy storage system, electric mopeds, electric motorcycles, safety specifications.

Key Topics and Technical Requirements

• Scope & intent: Safety requirements for RESS in electrically propelled mopeds and motorcycles; covers design, installation and component-level considerations aimed at person protection.
• Electrical classification & marking: Voltage class B components and wiring must be identified (symbol ISO 7010–W012) and cables conductively connected to RESS must use orange outer covering per ISO 13063-3.
• Isolation resistance: Required isolation resistance per maximum working voltage:
  • 100 Ω/V for DC-only RESS or AC RESS with additional AC protection;
  • 500 Ω/V for AC RESS without additional AC protection.
  • The standard recommends measuring isolation resistance before vehicles enter service.
• Creepage distance and clearance:
  • Formula-based creepage requirements when electrolyte leakage is possible:
    • Between terminals: d ≥ 0.25·U + 5 (mm)
    • Between live parts and electric chassis: d ≥ 0.125·U + 5 (mm)
  • Minimum clearance: at least 2.5 mm, with larger clearances recommended as voltage and current increase (tables in the standard provide ranges by U and current).
• Protection against hazards:
  • Controls for emission of hazardous gases and substances (prevention of hydrogen accumulation for open traction batteries).
  • Measures to prevent hazardous heat generation under first-failure conditions (temperature/current/voltage monitoring).
  • Design to prevent electrolyte spills reaching rider or nearby persons.
  • Requirements addressing accidental detachment, over-current interruption, and connectors for removable RESS.
• Documentation: Owner’s guide/manual requirements for safe use.

Applications and Users

This standard is intended for:

• Vehicle manufacturers and OEMs designing electric mopeds and motorcycles
• Battery and RESS system designers and integrators
• Electrical and safety engineers responsible for vehicle certification
• Test laboratories and conformity assessors performing isolation, creepage and clearance checks
• Regulatory bodies and fleet operators specifying safety requirements

Practical uses include design validation, component selection (connectors, enclosures), vehicle-level electrical safety verification, and preparing owner manuals.

Related Standards

• ISO 13063 series - Part 2: Vehicle operational safety; Part 3: Electrical safety (see ISO 13063-3 for electrical test methods and wiring colour rules)
• ISO 18243 - Test specifications and safety requirements for lithium‑ion battery systems

Using ISO 13063-1 helps ensure RESS designs for electric mopeds and motorcycles meet internationally recognized safety specifications for person protection.

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.

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 38,
Motorcycles and mopeds.
This first edition of ISO 13063-1, together with ISO 13063-2 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;
— requirements for lithium-ion batteries refer to ISO 18243;
— requirements for the connector of the removable RESS are provided.
A list of all parts in the ISO 13063 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
