28、es. Its theroretical average speed is 18,77 km/h. Test sequence no 2 is composed of two parts (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, ex
29、cept the changing gear steps. In the case where the vehicle is fitted with a manual gear box with 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
30、test driver, the one to best match the reference curve shall be selected. 4.1.1 Urban cycle The 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. Categories of vehicles M, Ma, NI and N, are
31、defined in Directive 9Z63EEC. 2, Motor tricycles and quadricycles are defined in Directive 92/61/EEC.

36、 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 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 ref

Th
40、e choice shaU be noted in the test report. The choice between the two possibilities can be guided with the following considerations: - requirement from the test orderer, - comparative test between several electsic vehicles, whereas the first possibility (seven times test sequence no 1) is more appro
41、priate, especially when one of the vehicles is not able to follow the speed target curve of the extra-urban part of the test sequence no 2; - comparative test between the electric vehicle and an Internal Combustion Engine vehicle, whereas the second possibility (two times test sequence no 2) is more
42、 appropriate. 6.2 Equipment All the equipment requirements of Directive 91/441/EEC shall apply 6.3 Parameters, units and accuracy of measurements Table 3.

46、he procedure recommended by the vehicle manufacturer in order to keep the temperature of the battery in the normal operating range. The vehicle manufacturer agent shall be in a position to attest that the thermal management system of the battery is not off, neither reduced. f) The vehicle shall have
47、 been driven at least 300 km in the seven days before the test with those batteries that are instailed in the test vehicle. 5.4.2 Ambient temperature conditions For all the test steps which are carried out outside, the ambient temperature shall be between 5 “C and 32 “C. For those test steps which a
48、re carried out indoors, the ambient temperature shall be between 20 “C and 30 “C. 5.6 Test procedure The test procedure includes the four following steps: - initia charge of the battery; - application of either seven times test sequence no 1 or two times test sequence no 2 as defined in 4.1; - charg
49、e of the battery; - calculation of energy consumption. Between each step, if the vehicle moves, it shall be pushed to the following test area (without regenerative recharging).
