30、 conditions a) The vehicle shall be loaded according to the specifications for each test. b) The vehicle tyres shall be inflated to the pressure specified by the vehicle manufacturer when the tyres are at the ambient temperature. c) The viscosity of the oils for the mechanical moving parts shall con
31、form to the specifications of the vehicle manufacturer. d) The lighting and light signalling and auxiliary devices shall be off, except those required for testing and usual day-time operation of the vehicle. e) All energy storage systems available for other than traction purposes (electric, hydrauli
32、c, pneumatic etc.) shall be charged up to their maximum level specified by the vehicle manufacturer. f) The vehicle shall be clean and the windows and air entries, not needed for the correct operation of the vehicle and the drive system, shall be closed by the normal operating controls. g) The vehic
33、le shall have been driven at least 300 km in the seven days before the test with the traction battery that is installed in the test vehicle. h) The traction battery shall be in the state of charge required for the test to be performed. i) Preconditioning shall be as prescribed in each test or series
34、 of tests. 6.2 Atmospheric conditions a) For all the test steps which are carried out outside the ambient temperature shall be between 5 C and 32 C inclusive. b) For those test steps which are carried out indoors, the ambient temperature shall be between 20 C and 30 C inclusive. c) The atmospheric p
35、ressure shall be comprised between 94 kPa and 104 kPa inclusive. d) The average wind speed measured at a height of 1 m above the ground shall be less than 3 m/s, gusts shall be less than 5 m/s. e) The relative humidity shall be less than 95 %. f) Rain and fog shall be absent. 6.3 Road conditions The
36、 measurements shall be performed on a dry track, which is either a straight track in the conditions set out in 6.3.1 or a loop track in the conditions set out in 6.3.2. The surface of the track shall be hard, smooth, clean and give good adhesion. 6.3.1 Straight track The length of the measuring zone
37、 shall be at least 1000 m. The length of the launching tracks shall be long enough to achieve a stable speed 200 m ahead of the measuring zone. The longitudinal slope on the measuring zone and on the last 200 m of the launching tracks shall not exceed 0,5 %. The longitudinal slope on the launching t
38、racks shall not exceed 4 %. The transverse slope on the measuring zone shall not exceed 3 %. In order to reduce the influence of factors such as road slope and wind direction/speed, the acceleration and speed performances shall be executed in both directions of travel, in direct sequence, taking car
39、e to use the same stretch of the track. When conditions preclude performing the test in both directions, a single direction test shall be carried out in accordance with 6.3.3. 6.3.2 Loop track The length of the loop shall not be less than 2000 m. For calculating speeds, the length of the run shall b
40、e the distance actually covered by the vehicle while it is being timed. In plan, the loop track can vary from a perfect circle to straight sections linked by approximately circular sections. The radius of curves shall not be less than 200 m. The longitudinal slope, in the measuring zone shall not ex
41、ceed 0,5 %. The effects of centrifugal force shall be compensated by the transverse profile of the curves in such a way that the vehicle holds a normal line without any action on the steering wheel. 6.3.3 Single direction test Testing in one direction only shall be permitted if, because of the test
42、track layout, it is not possible for the vehicle to reach its maximum speed in both directions. In this case, the track shall conform to the requirements of 6.3.1; additionally, the variation in altitude shall not exceed 1 m between any two points. The component of wind speed parallel to the track s
43、hall not exceed 2 m/s. The run shall be performed twice in immediate succession.Page 5 EN 1821-1 : 1996 BSI 1997 7 Preconditioning of the vehicle 7.1 Battery charge The battery shall be charged according to the following procedure. 7.1.1 Normal charging procedure The battery charge shall be carried
44、out with the on board charger if fitted. If not, the charge shall be carried out with an external charger recommended by the vehicle manufacturer. The connection shall be carried out with the domestic plug as recommended by the vehicle manufacturer, in an ambient temperature between 20 C and 30 C. T
45、he procedure excludes all types of special charges, for instance, the equalization charges or the servicing charges. The vehicle manufacturer shall be in a position to attest that during the test, a special charging procedure has not occurred. 7.1.2 End of charge criteria The end of charge criterion
46、 corresponds to a charging time of 12 h unless a clear indication is given to the driver by the standard instrumentation that the battery is not yet fully charged. In this case, the maximum time is: 33 manufacturers specified battery energy capacity mains power supply where: manufacturers specified
47、battery energy capacity is expressed in kilowatt hours; mains power supply is expressed in kilowatts. 7.1.3 Fully charged battery A battery is fully charged when it is charged in accordance with normal charging procedure until the end of charge criteria. 7.2 Trip meter setting The on board trip mete
48、r shall be set to zero, if not the mileage shall be recorded. 7.3 Warm-up The vehicle shall be driven over a distance of about 5000 m at 80 % of the vehicle manufacturers estimated maximum thirty minute speed in order to preheat the motor and transmission gears. 8 Test sequence The test sequence is
49、arranged such that all the road performance tests can be performed within two days. It shall be performed according to the following sequence: a) first day: preconditioning of the vehicle (in accordance with clause 7); test: maximum thirty minute speed (in accordance with 9.1); complete battery discharge (in accordance with 9.2); b) second day: preconditioning of the vehicle (in accordance with clause 7); test: maximum speed (in accordance with 9.3); 40 % battery discharge: reach 40
