ISO 13064-1:2012

Overview - ISO 13064-1:2012 (Battery-electric mopeds and motorcycles)

ISO 13064-1:2012 specifies standardized test procedures to determine the reference energy consumption and reference range of battery-electric mopeds and motorcycles that use only traction battery(ies) for propulsion. The standard defines repeatable test sequences, charging procedures, measurement points and the formula for calculating reference energy consumption (C = E / d), enabling consistent lab and field evaluation of electric two-wheel vehicle performance.

Key technical topics and requirements

• Scope: Applies to battery-electric mopeds and motorcycles with traction batteries as the sole propulsion source.
• Test sequences: Defined driving cycles are given in Annex A (mopeds), Annex B (motorcycles) and a constant speed option in Annex C. Tests repeat prescribed cycles until the end-of-test criterion is met.
• Tolerances and timing:
  • Speed tolerance ±2 km/h and time tolerance ±1 s; these are geometrically combined.
  • One deviation up to 4 s allowed per drive cycle; total timeout must be reported.
• End-of-test criteria: Specified in the annexes or by on-board instrumentation indicating the driver should stop.
• Measurement parameters and accuracy (examples from Table 1):
  • Time: ±0.1 s; Distance: ±0.1 %; Speed: ±1 %; Mass: ±0.5 %; Energy measurement to IEC class 0.2 S.
• Battery charging and conditioning:
  • Batteries charged per manufacturer recommendation (normal overnight charging procedure described).
  • End-of-charge determined by manufacturer instrumentation; charging time ≤ 12 h for end-of-charge indication.
  • Recommended battery usage: preferably batteries with ≤ 50 charge/discharge cycles.
• Test conditions:
  • Vehicle load, tyre pressure, lubrication and auxiliary systems specified.
  • Ambient ranges: outdoor 5 °C–35 °C; indoor 20 °C–30 °C; atmospheric pressure 91–104 kPa; relative humidity <95 %.
  • Wind limits for outdoor testing: average ~3 m/s, gusts ≤5 m/s.
• Calculation: Reference energy consumption C (Wh/km) = measured energy E (Wh) delivered from mains during recharge divided by range d (km).

Practical applications - who uses ISO 13064-1:2012

• Vehicle manufacturers - to validate design targets, publish consistent range/consumption figures, and support homologation.
• Testing laboratories and certification bodies - for type approval, compliance testing and standardized reporting.
• R&D and benchmarking teams - to compare powertrain efficiency, battery conditioning and control strategies across models.
• Regulators and policymakers - to set performance labeling, consumer information and fleet procurement criteria.
• Aftermarket and consulting services - to verify energy claims and support optimization for range and charging processes.
