13、federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that c
14、ommittee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in acco
15、rdance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requi

39、the RESS 6.1.1 General The measurement of the isolation resistance of the RESS shall include auxiliary components located inside the RESS housing, e.g. monitoring or temperature-conditioning devices and liquid fluids (if any). Both terminals of the RESS generally have different isolation resistances
40、 (Ri1and Ri2in Figure 2) against the electric chassis. For safety reasons, the lower one is regarded as the relevant RESS isolation resistance, which can be calculated using voltages measured in a procedure taking the voltage of the charged RESS as the test voltage. 6.1.2 Preconditioning and conditi
41、oning For the measurement of the RESS isolation resistance within the vehicle, i.e. the RESS installed as for normal operation, both power terminals of the RESS shall be disconnected from the electric propulsion circuit and any other external circuit. Terminals of the internal auxiliary systems of t
42、he RESS that are operated by power sources outside the RESS (e.g. the auxiliary 12 V battery) shall be disconnected from the outside power source and connected to the electric chassis of the vehicle, except for terminals that are required to activate the RESS (e.g. by connecting the battery packs in
43、side a traction battery to the power terminals). For the measurement of the RESS isolation resistance outside the vehicle (the RESS as a stand-alone system) the electric chassis shall be simulated by an electric conductor, e.g. a metal plate, to which the RESS shall be attached with their standard m
44、ounting devices, for best representing the resistances between the RESS housing and the electric chassis of the vehicle. Prior to the measurement, the RESS shall be subjected to a preconditioning period of at least 8 h at (5 2) C, followed by a conditioning period of 8 h at a temperature of (23 5) C
45、, a humidity of 90105+%, and an atmospheric pressure between 86 kPa and 106 kPa, in order to reach the dew point. Alternative preconditioning and conditioning parameters may be selected, provided transition across the dew point occurs shortly after the beginning of the conditioning period. The speci
46、fic conditions of the RESS type and usage shall be considered. If possible, the RESS should be charged to the maximum state of charge recommended by the vehicle/RESS manufacturer. For measurements within the vehicle, if the RESS is rechargeable only from on-board energy sources, the RESS should be c
47、harged at any state of charge within the normal operation level that is appropriate for measurement, as defined by the vehicle manufacturer. The voltmeter or the measuring device used in this test shall have an internal resistance above 10 M. BS ISO 6469-1:2009ISO 6469-1:2009(E) ISO 2009 All rights
48、reserved 56.1.3 Procedure The isolation resistance shall be measured during the conditioning period at a rate, from which the lowest resistance value can be determined. If switches for the battery current are integrated in the RESS, they shall be closed during the measurement. The procedure for each
49、 measurement is the following see Figure 2 and Equations (1) and (2): Measure the voltages between each terminal of the RESS and the vehicle electric chassis, and name the higher one U1, the lower one U1and the two corresponding isolation resistances Ri1and Ri2= Ri. NOTE 1 Ri2is the lower isolation resistance and is therefore the RESS isolation resistance Rito be determined. Add a known measuring resistance R0parallel to Ri1and measure the voltages U2and U2.
