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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
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.
ISO 13064-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 23, Mopeds.
ISO 13064 consists of the following parts, under the general title Battery-electric mopeds and
motorcycles — Performance:
— Part 1: Reference consumption and range
— Part 2: Road operating characteristics

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 13064-2 and the following apply.
3.1
reference energy consumption
quantity of electric energy from the mains needed to charge the traction battery, divided by the distance
covered after the vehicle has been driven through the specified test sequence
NOTE 1 Taken from ISO 8713:2012, definition 2.62.
NOTE 2 The reference energy consumption is usually expressed in watt-hours per kilometre (Wh/km)
3.2
reference range
distance covered by an electrically propelled vehicle over a designated test sequence on a fully charged
traction battery, to the end of the test sequence as defined by the end of test sequence criteria
NOTE 1 Taken from ISO 8713:2012, definition 2.63.
NOTE 2 The reference range is usually expressed in kilometres (km).

4 Test sequence
The test sequence for mopeds is defined in Annex A of this part of ISO 13064.
The test sequence for motorcycles is defined in Annex B of this part of ISO 13064.
The same test sequence shall be used to define energy consumption and range. Every effort shall be
made to conduct the tests by following the reference curve within the tolerances given in Clause 5.
The constant speed test sequence for mopeds and motorcycles are defined in Annex C of this part of ISO 13064.
5 Tolerances
Tolerances on speed and time in the test sequence shall be as shown in Figure 1.
Key
X time, s
Y speed, km/h
1 reference curve
2 tolerance of speed, in kilometres per hour (km/h)
3 tolerance of time, in seconds (s)
Figure 1 — Reference curve and tolerances
A tolerance on speed of ± 2 km/h and a tolerance on time of ± 1 s shall be geometrically combined at each
point as in Figure 1.
One deviation of up to 4 s beyond these tolerances is permitted in any drive cycle. This exception shall
not be allowed to delay the determination of the end of the test sequence.
The total time-out of tolerances shall be mentioned in the test report.
6 End of test sequence criterion
The criterion for the end of the test sequence shall be as specified in Annexes A, B or C or shall be an
indication from the on-board instrumentation, given to the driver, to stop the vehicle.

7.3 Test conditions
7.3.1 Vehicle conditions
The vehicle shall be loaded according to specification of the test.
The vehicle tyres shall be inflated to the pressure specified by the vehicle manufacturer according to the
test chosen (track or chassis dynamometer) when the tyres are at ambient temperature.
The viscosity of oils used for the lubrication of mechanical moving parts shall conform to the specifications
of the vehicle manufacturer.
The lighting and light signalling and auxiliary devices shall be off, except those required for testing and
usual day-time operation of the vehicle.
All energy-storage systems available for other than traction purposes (electric, hydraulic, pneumatic,
etc.) shall be in the operating range specified by the vehicle manufacturer.
For the traction battery conditioning, the test driver shall follow the procedure recommended by the
vehicle manufacturer for keeping the temperature of the battery in the normal operating range. The
vehicle shall be run in properly in accordance with the manufacturer’s requirements, and in any case not
less than 100 km before the test with those batteries that are installed in the test vehicle.
The mass of the vehicle used in the test shall be in accordance with ISO 13064-2:2012, 3.1 and 3.2.
It is recommended to only use batteries that didn’t go through more than 50 charge/discharge cycles.
7.3.2 Atmospheric conditions
Outdoor test steps shall be carried out at an ambient temperature between 5 °C and 35 °C.
Indoor test steps shall be carried out at room temperature between 20 °C and 30 °C.

ISO 13064-1:2012(E)
The relative humidity shall be less than 95 %.
The tests shall be performed in the absence of rain and fog.
For outdoor testing, the wind shall be steady. The wind speed and the direction of the wind shall be
measured continuously or with adequate frequency at a location where the wind force during the
measurement is representative. The wind conditions shall be within the following limits:
a) average wind speed: 3 m/s;
b) maximum wind speed for gusts: 5 m/s.
7.3.3 Driving selection mode
In case of two or more manually selectable driving modes, tests shall be conducted for each single
mode, and at least the worst case shall be mentioned in the test report. If the manufacturer can provide
evidence that proves what is the worst case mode, it is allowed to only test such mode.
7.4 Test procedure
7.4.1 General
The test procedure consists of the following four steps:
a) initial charging of the traction battery (see 7.4.2);
b) application of the appropriate test sequence, and measurement of the reference range and
consumption at the stationary external power source (see 7.4.3);
c) charging of the traction battery and measurement of the energy consumption at the mains (see 7.4.4);
d) calculation of the reference energy consumption (s
