4 EPS specification
4.1 DC plug connector specification
The cable assembly supplied with the EPS shall terminate in a USB Micro-B plug, defined in
IEC 62680-2-2. The cable assembly may be permanently connected to the EPS or may be a
detachable cable. In either case, the terminating USB Micro-B plug shall be compliant with the
USB Micro-B cables and connectors specification, IEC 62680-2-2.
The cable assembly supplied with the EPS may also terminate in a non USB Micro-B plug if a manufacturer makes available an adaptor from the Micro-USB connector of a common EPS to a specific non-Micro-USB socket in the mobile phone.2
An EPS provided with a detachable cable shall be equipped with a USB Standard-A receptacle to connect to the EPS. The detachable cable assembly, supplied for use with the EPS, shall have USB Standard-A and USB Micro-B plugs and meet the USB-IF cable assembly requirements in IEC 62680-2-2.
The above requirement also applies to a cable used as an adaptor, i.e. when the USB Micro-B is connected to the mobile telephone by an adaptor where the mobile telephone does not have a Micro-USB interface.
4.2 AC input characteristic
The EPS shall meet the requirements of IEC 60950-1 or IEC 62368-1 with a maximum touch current not exceeding 90 pA.
The EPS AC input shall operate over the following range:
— voltage range: the rated input voltage range covers the range 100 V to 230 V;
— frequency: 50 Hz to 60 Hz.
4.3 Environmental specification
The EPS operational environmental range, over which the DC output characteristics defined
in 4.4 shall be maintained, shall be
— temperature range: 0 °C to +35 °C,
— relative humidity: up to 90 %.
4.4 DC output characteristics
The DC output voltage of the EPS shall be as specified in IEC 62680-2-1. The cable voltage drop shall be as specified in IEC 62680-2-1.
The ripple voltage on the output with a no-load current to maximum rated output current shall be no more than 80 mV peak-to-peak measured at 20 MHz bandwidth when measured in accordance with the test method defined in 5.2.
Proprietary methods for faster charging at higher voltages and/or currents are permitted, provided that interoperability according to IEC 62680-1-1 is guaranteed when the peer connected device (EPS or the mobile telephone) supports only IEC 62680-1-1.
4.5 Protection
The EPS shall comply with all appropriate safety standards, for example as specified by
IEC 60950-1 or IEC 62368-1.
4.6 EPS detection
To enable the mobile telephone to detect that it is connected to an EPS, the EPS shall meet the USB-lF charging port requirements for a Dedicated Charging Port as defined in
IEC 62680-1-1.
4.7 Reliability
The durability of the plug and receptacles shall, as a minimum, meet the performance as
given in Table 6-7 of IEC 62680-2-1:2015.
5 Testing requirements
5.1 General
The requirements in Clause 5 have been developed to try to ensure that common hPSs perform correctly with any data-enabled mobile phone to which they may be connected. Most of the requirements can be verified using existing and well-understood measurement techniques, which do not need defining in this document.
The ripple voltage at the DC output can be affected by the load on the output of the EPS. For these parameters, the test procedures outlined in 5.2 shall be used.IEC 62684 pdf download.
