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)
