ISO 13063-2:2022

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
