This European Standard shall be given the status of a n
18、ational 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of an identical text or by endorsement, at the latest by October 2001, and conflicting national standards shall be withdrawn at the latest by October 2001.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 r
19、ange 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 vehic
20、le 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); thermal electric hybrid vehicles where the thermal engine has such a low level of power 1)compared to that of the
21、 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 electrica
22、lly 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 withi
23、n 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 Measure
24、ment 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/CENEL
25、EC 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, Swit
26、zerland and the United Kingdom.1)In order to be able to use existing measuring facilities.EN 1986-2:2001 4 1 Scope This standard aims at defining the range in pure electric driving mode and the consumption measurements for a thermal electric hybrid road vehicle from M 1 , N 1 , or M 2 2)category, an

This standard applies to the above-mentioned vehicles whose range and consumption can be tested following the provisions already laid down for conventional vehicles (i.e. Internal Combustion Engine vehicle) from the equivalent categories

32、 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 e
33、lectric energy 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. s
34、hould not be considered as electric hybrid vehicles, in so far they do not participate to the traction.2)Categories of vehicle M 1, N 1, and M 2 are defined in Directive 92/53/EEC. In practice, tricycles and quadricycles with a maximum speed over 45 km/h fall within the scope of this standard. 3)Mot
35、or tricyles and quadricycles are defined in Directive 92/61/EEC.EN 1986-2:2001 5 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
36、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
37、(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 driv
38、er, 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 hyb
39、rid 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
40、 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
41、 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
42、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; for the ancillary devices: electronic controllers an
43、d a cooling system.EN 1986-2:2001 6 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 alte
44、rnative 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 ele
45、ctric 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, o
46、r 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 sma
47、ller 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 hyb
48、rid mode shall be performed in pure thermal mode following strictly Directive 80/1268/EEC as amended 4) . 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 hybr
49、id 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 o
