Introduction
This document prescribes the usage of the wireless power transfer technology to charge electrically
propelled road vehicles and has been developed based on ISO/PAS 19363.
Status of technological development:
This document specifies requirements for on-board components of a wireless power transfer systems.
It gives guidance in terms of safety and performance and additionally addresses interoperability to
off-board components from different manufacturers to, for example support the development of public
wireless charging infrastructure. Even if the technology itself is well known, the implementation in a
vehicle is new and demands to meet the very specific requirements of the automotive industry. This
document is based on limited experience with series development and production. Current and future
product developments will continuously prove (and disprove) the applicability of this document to
further improve the contents, especially regarding the interoperability between systems from different
manufacturers.
Cooperation during document development:
This document has been developed in intense cooperation with IEC/TC 69 WG7, which is establishing
the IEC 61980 series. The IEC 61980 series covers the requirements for the off-board components in
correspondence to the application of on-board components according to this document. Furthermore,
SAE J2954 is standardising wireless power transfer systems in the United States of America. An
exchange between the groups was continuously sustained during the document development. Even
though there is no complete harmonization at this stage, several contents are comparable.

5 Requirements regarding environmental conditions
Components of the EV device installed at the underbody of the EV shall have IP degree IP6K7 and
IP6K9K according to ISO 20653.
The environmental requirements applicable to a particular EV device shall be identified and agreed
between the vehicle manufacturer and the supplier. The EV device shall withstand and retain its
degree of protection under the typical mechanical loads and stresses the EV device is subjected to in its
intended mounting position.
NOTE ISO 16750 (all parts) and ISO 21498 (all parts) contain information for guidance.
6 Classification
This document specifies requirements that address the following aspects of MF-WPT systems:
— system safety (Clause 10),
— system performance (Clause 7), and
— interoperability.
ISO 19363:2020(E)
Requirements regarding system safety and system performance are relevant and applicable for safe
operation of any MF-WPT system (including dedicated single-supplier solutions) while still assuring
some base level of performance.
The interoperability requirements supplement the safety and performance requirements in order to
allow for interoperability of a supply device and an EV device provided by independent suppliers.
Two compatibility classes have been specified to accommodate these design considerations:
— Compatibility class A: EV devices of this class are intended for interoperable application and are
required to meet a set of safety and performance requirements. Cross-supplier interoperability is
tested with the normative reference supply power circuits as specified in this document.
— Compatibility class B: EV devices of this class are not intended for interoperable application but still
are required to meet the set of safety requirements; performance requirements may be different
than those of compatibility class A. EV devices of this class are tested with supplier-specified supply
power circuits.
7 MF-WPT power transfer requirements
7.1 General
Unless otherwise specified the requirements in Clause 7 refer to EVPCs of both compatibility classes.
Conformance to the requirements in 7.2 to 7.6 is tested according to 7.7, whereas EVPCs of compatibility
class A are tested with the normative reference supply power circuits described in Annexes A and B,
and EVPCs of compatibility class B are tested with supplier specific supply power circuits.
The supplier shall specify the rated conditions of an EVPC according to Table 1.

NOTE 1 Typically, the output voltage range of the EVPC is aligned with the voltage range of the RESS.
NOTE 2 7.3 gives additional information for the determination of centre alignment point(s).
7.2 Frequency
MF-WPT for EVs is allowed to operate in the frequency range of 79 - 90 kHz. The operating frequency
during power transfer is set by the supply device based on negotiations with the EV device.
7.3 Geometrical operating space
An EVPC shall meet the requirements of 7.4 and 7.5 within its geometrical operating space defined by
its secondary device ground clearance range and the alignment tolerance area according to Table 2.
6 © ISO 2020 – All rights reserved

ISO 19363:2020(E)
EVPCs of compatibility class B may have a specific alignment tolerance area that deviates from the
values in Table 2.

x ±75
y ±100
In case of MF-WPT between a primary device and a secondary device of different topologies, several
centre alignment points can exist. Examples are shown in Figure 2.
Key
1 centre alignment point of the EVPC
2 alignment tolerance area
3 direction of travel
Figure 2 — Example for centre alignment points between different coil topologies
The centre alignment points of supply power circuits are determined according to IEC 61980-3.
The centre alignment point(s) of the EVPC shall be specified with respect to the centre alignment points
provided by the supply power circuit.
The requirements in this document apply to all centre alignment points specified for an EVPC.
The vehicle manufacturer may specify only one centre alignment point for alignment with a primary
device of a different topology.
NOTE The selection of a single point can be due to a variety of reasons, for example the influence of the EV
on the distribution of the magnetic field or the position of the EV within a parking spot.
7.4 Requirements for output power
An EVPC shall be able to deliver power up to its rated output power when operated with a supply power
circuit.
An EVPC shall support the maximum ramp up rate of the supply power circuit. The maximum ramp up
rate of supply circuits for EVPCs of compatibility class A is specified in IEC 61980-3.
ISO 19363:2020(E)
7.5 Requirements for power transfer efficiency
Power transfer efficiency is the ratio of the output power of the EVPC (output of block #23 in Figure 1)
divided by the input power of the supply power circuit (input to block #13 in Figure 1).
An EVPC shall support the minimum power transfer efficiency according to Table 3 when operated at
rated output power with a supply power circuit.
An EVPC should support the minimum power transfer efficiency according to Table 3 when operated
at power levels below the rated output power. Typical local supply network connections should be
considered.
Table 3 — Minimum power transfer efficiency
Alignment Minimum power transfer efficiency
Centre alignment point 85 %
Within alignment tolerance area 80 %
7.6 Requirements for output voltage
7.6.1 Performance requirements at different output voltage levels
An EVPC shall meet the requirements of 7.4 and 7.5 within its geometrical operating space according to
7.3 throughout its specific voltage range when operated with a supply power circuit.
7.6.2 Voltage ripple and voltage overshoot
The DC output voltage overshoot, the peak voltage and the voltage ripple amplitude of an EVPC shall be
agreed between the vehicle manufacturer and supplier, taking into account the implication on the RESS
and other on-board components.
NOTE A typical value for DC output voltage overshoot is ±1 %/ms, a typical value for the peak voltage is
10 % of the nominal DC output voltage and a typical value of the DC output voltage ripple amplitude is ±8 V.
7.7 MF-WPT power transfer test procedure
7.7.1 General
This subclause describes the test setup and procedure to be applied for conformance testing of the
requirements specified in 7.2 to 7.6.
7.7.2 Test setup
7.7.2.1 Apparatus
7.7.2.1.1 General
MF-WPT is influenced by the materials in the close surroundings, especially by the material structure
of the EV. Reliable testing results can only be achieved, when influencing materials of the EV are
adequately represented in the test setup. This can either be accomplished by testing on vehicle level or
by including relevant parts of the vehicle when testing is done at component level according to 7.7.2.1.3.
7.7.2.1.2 Vehicle level testing

The EVPC shall be fixed to the EV at its intended mounting position.
NOTE This includes the positions of all components of the EVPC, in case they are not within one housing.
The load shall either be a RESS or a representative simulated DC load.
The supply power circuits to be used for testing the EVPC are described in 7.7.2.2.
The alignment shall be changeable in x-, y-, and z-direction to enable measurements at the alignment
points according to Table 4. Alignment adjustment may be realised by either moving the EV, moving the
supply power circuit or moving both.
The components of the test bench and the ground shall not significantly influence the MF-WPT. The
entire test setup may also be lifted to a height that avoids potential influences of the ground.
7.7.2.1.3 Component level testing
As an alternative for vehicle level, the testing may also be done on component level.

For EVPCs of compatibility class B, the values for x and y shall be in accordance with the specific
alignment tolerance area of the EVPC (see 7.3).
7.7.3.3 Output power and power transfer efficiency
At each alignment point described in 7.7.3.2 the supply power circuits according to 7.7.2.2 shall be
operated with the MF-WPT input power that is needed by the EVPC to provide its rated output power.
These measurements shall be performed at the following voltage levels:
— minimum voltage of output voltage range +50 % of output voltage range, and
— maximum voltage of output voltage range -10 % of output voltage range.
EXAMPLE For an output voltage range of 200 V to 400 V the corresponding voltage levels are 300 V and 380 V.
For EVPCs of compatibility class A, the normative reference supply power circuits shall be operated at
85 kHz. In case the performance requirements are not met, the frequency may be adjusted within the
range according to 7.2.
For EVPCs of compatibility class B, the supply power circuit shall be operated at the frequency according
to the specifications of the supplier within the range according to 7.2.
NOTE The MF-WPT input power of the normative supply power circuits is limited according to the
specifications in Annexes A and B, or, in case of compatibility class B testing, by the specifications of the supplier,
respectively.
The test is passed when the EVPC provides 90 % of its rated output power at all measurements and
fulfils the power transfer efficiency requirements according to 7.5 at all measurements. Examples are
given in Table 5.

When testing an EVPC of compatibility class A with the normative reference supply power circuit in
Annex A, exceptions apply for the following cases, where the rated output power of the EVPC cannot be
reached due to the limited MF-WPT input power of the normative reference supply power circuit:
1) The rated output power of the EVPC is higher than 3,7 kW.
2) The rated output power of the EVPC is equal or less than 3,7 kW.
For case 1), the test is deemed to have passed when the MF-WPT input power of the normative reference
supply power circuit reaches 3,33 kW (90 % of 3,7 kW) and the EVPC provides any output power.
For case 2), the test is passed when the MF-WPT input power of the normative reference supply power
circuit reaches 90 % of the rated output power of the EVPC and the EVPC fulfils the power transfer
efficiency requirements according to 7.5 at all measurements.

At alignment points 00P, 000, and 00N: measured output power > 85% of MF-WPT input power. At all other alignment
points: measured output power >80 % of MF-WPT input power.
7.7.3.4 Output voltage
In order to verify the requirements for the DC output voltage (as per 7.6.2), the following test shall be
applied:
It is recommended to connect the EVPC to an RESS, as used in the EV the EVPC is designed for.
The EVPC shall be placed in one of the alignment points with maximum misalignment. The power shall
be ramped up from zero to the rated output power of the EVPC with the maximum rate of supply power
circuits according to 7.4. The test is passed, when the DC output voltage is within the requirements of
7.6.2 during the entire test procedure.
8 Requirements for communication and MF-WPT activities
According to IEC 61980-2 the operation process for MF-WPT is modelled as a WPT session, which is
organized by a sequence of activities.
These activities are executed respectively supported by communication between the EV device and the
supply device, but also imply additional hardware requirements for components of an EV device beyond
the specifications in this document. The requirements for an EV device related to the execution of the
activities are described in IEC 61980-2. An EV device shall fulfil the applicable requirements given in
IEC 61980-2.
