10、S 19295:2016(E) Foreword ISO (the International Organization for Standardization) is a worldwide 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 subje
11、ct for which a technical committee has been established has the right to be represented on that committee. 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
12、) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be n
13、oted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifyi

17、ms for electrically propelled road vehicles. The requirements for voltage class B electric circuits that are used for electric power transfer for the propulsion of electric road vehicles are significantly different to those of voltage class A electric circuits used for powernets at, for example, 12
18、V d.c. or 24 V d.c. This PAS provides definition of voltage sub-classes for rechargeable energy storage system (RESS) and electric propulsion system and lists up specified values based on maximum working voltage. Voltage sub-classes listed in this PAS are used for voltage class B systems of all kind
19、s of current or future electrically propelled road vehicles. It enables vehicles manufacturers and automotive supply industry to evaluate the characteristics of a component according to the specified sub-class. The voltage sub-class itself and the component characteristics have large cost impact on
20、the component design and the overall design of the electric system. A high variety of different voltage sub-class and operating conditions hinders the use of an existing component in different vehicle models. Today, a huge variety of different RESS and electric propulsion system maximum working volt
21、ages are used for electrically propelled road vehicles on the market. Because some systems use voltage boost converters, maximum working voltage of electric propulsion system can be different from that of RESS. This variety of maximum working voltages often results from different numbers of cells in
22、 the design of the electrical energy source, e.g. battery stack or variety of power requirement by each vehicle. As a consequence, many system or component designs of a voltage class B electric circuit are currently related to one specific working voltage. When a maximum working voltage is selected
23、for the design, often only one supplier for a component is available. Hence, a change to another component supplier or a change of the dedicated maximum working voltage is not possible, when the system design is finished. It is necessary to reduce the variety of maximum working voltages in order to
24、lower the component and system costs by limiting the variety of maximum working voltages, decouple the system or component designs of a voltage class B electric circuit from the design of the electric energy source, enable an exchange of components from different suppliers during and after the syste
25、m development and to enable competition and access to the worldwide market for component suppliers, and support the system design by specifying basic voltage sub-classes for automotive propulsion systems within voltage class B. This PAS lists only those RESS and electric propulsion system voltage su
26、b-classes which are used or will be used in current or planned vehicle models and for which electronic parts, e.g. semiconductor switches, are currently available without any restrictions on the market. The range of voltage class B is too wide to be used for a component design referring to voltage.
27、Therefore, this PAS divides voltage class B in a set of voltages sub-classes, which enable a component design referring to voltage for each voltage sub-class. This specification is not intended to restrict the development of component performance or technology. It does not exclude the use of other m
28、aximum operating voltages for an individual system design.

44、es; voltage transients and ripple for components. The voltage ranges and operating status shall apply to all components for the selected voltage sub- class. The voltage sub-class depends on a vehicle project and shall be selected by an agreement between customer and supplier. The requirements in acc
45、ordance with Table 1 shall apply to a RESS when it is disconnected from the voltage class B electric circuit. Different requirements may be specified by the customer for a RESS when it is connected to the voltage class B electric circuit because the voltage of RESS is limited to the maximum working
46、voltage of the vehicle project and given by the number of battery cells. For each voltage sub-class, the corresponding working voltages, component operating status, overvoltage and under-voltage are described as follows. 4.2 Component operating status The operating status is introduced to describe t
47、he general operating behaviour of components that depends directly on the voltage at the terminals of a component of the voltage class B electric circuit and is mainly focused on performance and electrical power. In every operating status, the components shall fulfil the following requirements: it s
