19、being driven because the noise emission of the electric motor is negligible compared with that of an Internal Combustion (I.C.) engine. On the other hand, electric road vehicles emit noise when they are stationary and the battery is on charge. If an electric road vehicle is equipped with an on-board

20、 charger, this can be a source of noise during charging, together with a number of other components which may also be operating and producing noise. Such airborne noise should be minimised, to avoid public nuisance, and its intensity should be no higher than that permitted under existing limits or r

21、ecommendations. This is the reason why it is important to measure the noise emission of the whole vehicle under precisely defined conditions. The airborne acoustical noise emission is expressed in terms of the sound power level of the electric road vehicle. 1 Scope This standard specifies the proced

22、ure for measurement of the airborne acoustical noise emissions of electrically propelled road vehicles from category M 1 ,M 2 ,N 1 ,o rN 2 1 ) during charging, the vehicle being fitted with an on-board charger. 2 Normative references This European Standard incorporates by dated or undated reference,

For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated i

NOTE The complete vehicle kerb mass VKM includes, in addition to the de

27、finition of ISO 1176, the traction battery, on board charger, portable charger or part of it if provided as standard by the manufacturer of the vehicle. 1 ) Categories of vehicles M 1,M 2,N 1 and N 2 are defined in Directive 92/53 EECEN 12736:2002 (E) 5 4 Preconditioning of the vehicle 4.1 Before th

28、e test, the battery of the vehicle shall be discharged to a level of at least 50 % of discharge, as indicated by the state of charge meter in the vehicle. If there is no state of charge meter fitted to the vehicle, the battery shall be discharged to a level of at Ieast 50 % depth of discharge by dri

29、ving the vehicle over a distance and at a speed, which are determined by the vehicle manufacturer. 4.2 The vehicle tyres shall be inflated to the pressure specified by the vehicle manufacturer when the tyres are at the ambient temperature, thus keeping the vehicle stable on the test track. 5 Prepara

30、tion of vehicle 5.1 The test shall be carried out with the vehicle at its VKM according to IS0 1176. 5.2 The vehicle on board charger shall be connected to the mains electricity supply. 5.3 The test shall be carried out for worst case conditions; the vehicle manufacturer shall guarantee that all dev

31、ices capable of influencing the test result are in operation. Exception may be made for devices capable of operating for no more than 5 min in any period of 1 h; these may be switched off. If there are devices in the vehicle which cannot operate concurrently, the device with the Iargest influence on

32、 the test result shall operate. All devices shall operate at their normal operating power level. 6 Acoustical environment 6.1 Test site The test site shall be a track as defined in ISO 10844. 6.2 Background noise The background noise shall be at least 10 dB below the noise emitted by the vehicle und

33、er test. 6.3 Environmental conditions The ambient temperature shall be between 0 C and 42 C. It is recommended not to perform the measurements if the wind speed exceeds 5 m/s at the height of the microphone. 7 Acoustical measurement device The acoustical measurement device shall conform to the speci

34、fications defined in 5.1 in ISO 362:1998. 8 Operation mode 8.1 Position of microphones The vehicle is located at the centre of the track defined in ISO 10844. The microphone is located 2 m from the vehicle, 1,2 m above the ground for the six following positions: at the front and in the symmetry plan

35、e of the vehicle; at the rear and in the symmetry plane of the vehicle; respectively on the right and left sides and in the plane crossing the foremost axles;EN 12736:2002 (E) 6 respectively on the right and left sides and in the plane crossing the rear axles. 8.2 Duration of measurement It shall co

36、nform to the minimum values given in 7.5.3 in EN ISO 3744:1995. 8.3 Reading For each position, the total A-weighted sound power level shall be recorded. Only the highest value of the six readings shall be reported, in a similar manner as described in ISO 362. 9 Test report The following data shall b
