Foreword
This European Standard has been prepared by Technical Committee CEN/TC 301 "Electrically propelled road
vehicles", the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by October 2001, and conflicting national standards shall be withdrawn at the latest
by October 2001.
CEN TC301 is dealing with "Electrically propelled road vehicles". This title includes, in fact, a wide range of electric
road vehicles (see the definitions in EN 13447:2001) which can be divided as follows:
- pure electric vehicle : this is an electrically propelled and infrastructure independent exclusively electrically
supplied road vehicle ;
- road vehicle fitted with an electric transmission : this vehicle remains in the scope of CEN/TC301 but is
considered as a conventional (e.g. an internal combustion engine vehicle) vehicle with a specific transmission
(no standards to be developed);
1)
- thermal electric hybrid vehicles where the thermal engine has such a low level of power compared to that of
the power train may be treated as a pure electric vehicle from the measuring point of view;
- other infrastructure independent electric vehicles which are today called electric hybrid vehicles. These electric
hybrid vehicles can run with a zero level pollutant emission;
- infrastructure dependent electrically propelled road vehicles are excluded from application of this standard.
A large amount of work has been undertaken on electric hybrid vehicles, and there is still a lot to discover on these
vehicles which can, for instance, incorporate several driving modes (more than two);
To remain today within what is most common, the term thermal electric hybrid vehicle will be understood as an
electric road vehicle fitted with a thermal machine (which is fed with fuel).
This European Standard EN 1986 consists of the following parts, under the general title "Electrically propelled road
vehicles - Measurement of energy performances" :
- Part 1 : Pure electric vehicles ;
- Part 2 : Thermal electric hybrid vehicles ;
- Part 3 : Other electric hybrid vehicles than those fitted with a thermal machine.
Annex A forms an integral part of EN 1986-2.
Annex B to Annex E are for information only.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,
Switzerland and the United Kingdom.

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply (see also EN 13447:2001).
3.1
electrically propelled road vehicle
road vehicle in which electric energy is transformed by electrical machine(s) into mechanical energy for traction
purposes
NOTE Traction is the term used with the same meaning as propulsion, but for historical reasons, this is the most widely
used term.
3.2
electric hybrid (road) vehicle
hybrid (road) vehicle in which one of the reversible energy source delivers electric energy
2)
Categories of vehicle M , N , and M are defined in Directive 92/53/EEC. In practice, tricycles and quadricycles with a
1 1 2
maximum speed over 45 km/h fall within the scope of this standard.
3)
Motor tricyles and quadricycles are defined in Directive 92/61/EEC.

EN 1986-2:2001
3.3
thermal electric hybrid vehicle
electric hybrid vehicle in which the traction system contains a thermal machine
NOTE Vehicle integrating electric machine(s) for functional assistance to the engine such as load levelling devices, starter,
electrically driven auxiliary units, etc. should not be considered as electric hybrid vehicles, in so far they do not participate to the
traction.
3.4
pure electric mode
driving mode when only the secondary on board electric energy source delivers energy for traction purpose. The
pure electric mode can be either selected by the driver or automatically selected by the system
For definitions of primary or secondary on board electric energy source, refer to EN 13447:2001 (Terminology).
3.5
pure thermal mode
for a thermal electric hybrid vehicle is the driving mode which can be selected by the driver when only the
additional other kind of on board energy source (including the thermal machine) participates in the propulsion of the
vehicle. In this case, the on board secondary electric energy source is not active even for energy recovery
3.6
hybrid mode (for an electric hybrid vehicle)
another driving mode than the pure electric mode, if selected by the driver, or the pure thermal mode. All the on
board energy sources can participate in the propulsion of the vehicle in accordance with the management system
logic. The hybrid mode includes the pure electric mode when it is automatically selected by the system
3.7
series electric hybrid vehicle
series hybrid vehicle in which all energy sources deliver electric energy
3.8
parallel electric hybrid vehicle
electric hybrid vehicle for which the wheel propulsion is produced either by the electric drive train and/or by the
additional form of on board energy source delivering mechanical power, both through a transmission which can be
common or individual
3.9
on board energy source
subsystem of the traction system consisting of a combination of at least storage(s) and possibly converter(s),
transmission(s), ancillary device(s). The on-board energy source delivers energy to the power train for traction
purpose
EXAMPLE 1
For a pure electric vehicle, the on board energy source can be made of :
- for the storage : an electrochemical storage battery,
- for the energy delivery system : cables,
- for the ancillary devices : thermal management of the battery, on board charger, protection devices.
EXAMPLE 2
For a series thermal electric hybrid vehicle, the additional other kind of on board energy source can be made of :
- for the storage : a petrol tank,
- for the energy delivery system : a generating set including an IC engine plus an alternator and a rectifier,
---------------------- Page: 7 ----------------------
SIST EN 1986-2:2002
Page 6
EN 1986-2:2001
- for the ancillary devices : electronic controllers and a cooling system.
4 Measurement of the range in pure electric mode
The measurement of the range, in pure electric mode, of a thermal electric hybrid vehicle is the same as that
described in clause 6 of EN 1986-1:1997 for pure electric vehicles. The end of test criterion - as an alternative to
that already provided by EN 1986-1:1997 - is the switching-on of the thermal engine.
The test results can be given as in Annex E.
5 Measurement of the electric energy consumption in pure electric mode
The measurement of the electric energy consumption in pure electric mode of a thermal electric hybrid vehicle is
the same as that described in clause 5 of EN 1986-1:1997 for pure electric vehicles.
If the range in pure electric mode of the thermal electric hybrid vehicle is smaller than the required distance in
clause 5 of EN 1986-1:1997 (i.e. seven times test sequence 1, about 28 km, or two times test sequence 2, about
22 km), then the test may be done with the highest possible whole number of cycles (sequence 1, about a multiple
of 4 km, or sequence 2, about 11 km), compatible with the measured range.
If the range in pure electric mode of a thermal electric hybrid vehicle is smaller than one cycle of sequence 1, then
the measurement procedure of the electric energy consumption is not applicable.
The test results can be given as in Annex E.

6 Measurement of the consumption
6.1 Principle
If a pure thermal mode can be selected by the driver, the test of the consumption in hybrid mode shall be
4)
performed in pure thermal mode following strictly Directive 80/1268/EEC as amended . Then, the thermal electric
hybrid vehicle behaves like a thermal engine vehicle, and no test procedure in hybrid mode is required.
Otherwise, the whole test procedure has to be fulfilled in hybrid mode (see 6.7).
The following test procedure ensures that the additional other form of on board energy source participates to the
propulsion of the vehicle (thermal engine). This is the reason why the total distance travelled shall exceed the
range of the vehicle in pure electric mode, thus implying at least one cold start of the thermal engine.
Annex A completes the operation mode, defines the measurements to perform and the calculations.
6.2 Cycle
A cycle comprises four urban cycles followed by one extra-urban cycle (test sequence 2) as defined in 4.1 of
EN 1986-1:1997.
6.3 Equipment
5)
All the equipment requirements of Directive 70/220/EEC as amended apply.
The calibration of the chassis dynamometer is carried out according to Annex A of EN 1986-1:1997.
6.4 Fuel
5)
The fuel used for the test shall be that defined by Directive 70/220/EEC as amended .
4)
At the time of the elaboration of this standard, Directive 80/1268/EEC was last amended by directive 93/116/EC. In the case of
further amendments, a check of their compatibility with this standard should be undertaken.
5)
At the time of the elaboration of this standard, Directive 70/220/EEC was last amended by Directive 96/69/EC. In case of
further amendments, a check of their compatibility with this standard should be undertaken.
