27、, divided by the test distance travelled, that the vehicle uses after driving one of the two proposed test sequences (see 4.1), from a fully charged battery, expressed in watthours per kilometre. 3.2 range Distance covered in kilometres by an electric vehicle over the test sequence n o 2 from a full
28、y charged battery (see 7.1.3 in EN 1821-1 : 1996) to the end of test criteria. 4 Test sequences 4.1 Composition Test sequence n o 1 (see figure 1) is composed of one urban cycle made of four basic urban cycles. Its theroretical average speed is 18,77 km/h. Test sequence n o 2 is composed of two part
29、s (see figure 1): an urban cycle made of four basic urban cycles; an extra-urban cycle. Its theoretical average is 33.6 km/h. NOTE. These cycles are the same as those described in Directive 91/441/EEC, except the changing gear steps. In the case where the vehicle is fitted with a manual gear box wit
30、h several gears, the test driver shall change the gear in order to best match the reference curve. If the vehicle has several driving modes (sport, comfort, economical, etc.) which can be selected by the test driver, the one to best match the reference curve shall be selected. 4.1.1 Urban cycle The
31、urban cycle is composed of four basic cycles of 195 s each and lasts 780 s in total. The description of the basic urban cycle is given in figure 2 and table 1.Page 4 EN 1986-1 : 1997 BSI 1997 1 Urban cycle = Test sequence n o 1 2 Extra-urban cyle (see figure 3) 3 Basic urban cycle (see figure 2) 1 +

Extra-urban cycle 4.1.2 Extra-urban cycle The description of the extra-urban cycle is given in figure 3 and table 2. 4.2 Tolerances
37、Tolerances on speed to be observed in following the test sequences n o 1 and n o 2 are given in figure 4. Tolerances on speed ( 2 km/h) and on time ( 1 s) are geometrically combined at each point as represented in figure 4. Below 50 km/h, the deviations beyond this tolerance are permitted as follows
38、: at gear changes for a duration less than 5 s; and up to five times per hour at other times, for a duration less than 5 s each. The total time out of tolerance has to be mentioned in the test report. Over or equal to 50 km/h, it is accepted to go beyond tolerances provided the accelerator pedal is
39、fully depressed. 4.3 End of test sequence criteria The end of test sequence criteria is when the vehicle is not able to meet the reference curve up to 50 km/h, or when an indication from the on board instrumentation is given to the driver that he has to stop the vehicle.Page 7 EN 1986-1 : 1997 BSI 1

44、 consumption 5.1 Principle The test method described hereafter permits to measure the electric energy consumption at the mains, in Wh/km, after having performed seven times test sequence n o 1 or two times test sequence n o 2. The choice shall be noted in the test report. The choice between the two
45、possibilities can be guided with the following considerations: requirement from the test orderer; comparative test between several electric vehicles, whereas the first possibility (seven times test sequence n o 1) is more appropriate, especially when one of the vehicles is not able to follow the spe
46、ed target curve of the extra-urban part of the test sequence n o 2; comparative test between the electric vehicle and an Internal Combustion Engine vehicle, whereas the second possibility (two times test sequence n o 2) is more appropriate. 5.2 Equipment All the equipment requirements of Directive 9
47、1/441/EEC shall apply. 5.3 Parameters, units and accuracy of measurements Table 3.
