Introduction
The electrical interface for charging electrically propelled vehicles with plugs, socket-outlets, vehicle
connectors and vehicle inlets is described in EN 62196 series and EN 61851-23. For heavier vehicles such
as buses and trucks, requirements of short charging times with high energy present a problem of handling,
and safety with hand-held connecting devices. For these high current charging applications, an automated
connection device (ACD) is of interest.
An automated coupler consists out of a mobile assembly with electrical contacts, called ACD and fixed
electrical contacts, called ACD counterpart. Automated couplers allow an unmanned connection of high-
current contacts and signal/control contacts.
This document contains requirements for all type of ACDs. Its annexes describe specific implementations
and specific requirements. This document is expected to be read in conjunction with IEC 61851-23-1:— .

Under preparation. Stage at time of publication: IEC CDV 61851-23-1:2020.
1 Scope
This document is applicable to ACDs of standardized configuration, intended for use in electric vehicle
conductive charging systems which incorporate control means, with rated operating voltage up to 1 500 V
DC.
This document applies to high power DC interfaces intended for use in isolated conductive charging systems,
for circuits specified in IEC 61851-23-1:— .
The ACDs covered by this document are used only in charging mode 4, according to IEC 61851-23-1:— ,
3.1.201 Case D or 3.1.202 Case E.
This document describes the requirements for an ACD in regard of safety, function and testing. This
document describes basic parameters that can be standardized for different ACDs. ACDs following these
standardized parameters will have the benefit of being compatible, even if they are based on different
technologies.
This document does not apply to solutions based on a vehicle connector described in EN 62196-3 driven by
an automated mechanism, as, for instance, a robotic arm.
This document does not cover all safety aspects related to maintenance.

4.1 Voltage and current requirements
4.1.1 Number of contacts
For systems described in IEC 61851-23-1:— , Annexes AA, BB and CC:
1 1
Four contacts: DC+, DC-, PE and CP (IEC 61851-23-1:— , Figure AA.1, IEC 61851-23-1:— , Figure BB.1
and IEC 61851-23-1:— , Figure CC.14)
For systems described in IEC 61851-23-1:— , Annex KK:
three contacts: DC+, DC-, PE (IEC 61851-23-1:— , Figure KK.14)

Under preparation. Stage at time of publication: IEC CDV 61851-23-1:2020.
4.1.2 Quality of DC charging voltage
Since the ACD is part of the power transmitting system, its influence on the quality of DC charging voltage
shall be considered, to not exceed the levels indicated in IEC 61851-23-1:— .
4.1.3 Rated continuous current
The maximum current may exceed the limits defined in EN 62196-1. The rated current can be a continuous
current or the average of an intermittent current.
The rated current is defined by the vehicle and the application. The manufacturer of the ACD shall guarantee
that his system is sized and safe for this current by confirming the physical values described in this document.
In the case of an automated coupler consisting of an ACD and an ACD counterpart from different or unknown
manufacturers, the minimum current requirements that fulfil the requirements for a particular annex of this
document shall be assumed unless there are sensing devices that can reliably determine if the ACD is
operating within the defined limits of this document. However, if the ACD and the ACD counterpart can be
definitively determined to be of a particular type and manufacturer, higher currents with or without sensing
devices can be used, according to manufacturer’s specifications.
4.1.4 Short-circuit current
In case of short circuit, the ACD shall not cause dangerous situation such as an explosion or a fire. After
such a short circuit, the ACD shall be checked for proper function prior further service.
As in ISO 17409:2020 leaf the short-circuit value for systems with an automated coupler open, an automatic
coupler shall be designed that way that it withstands a short-circuit current of 12 000 000 A s to be on a safe
side.
NOTE  12 000 000 A s can be reached with 34 600 A in 10 ms or 11 000 A in 100 ms or 3 460 A in 1 s.
The ACD shall be designed in such a way that a peak current of 30 kA, considered in ISO 17409:2020,
7.2.4.2 shall not lead to damages or dangerous situations in regard of the Lorentz force etc.
4.1.5 Maximum temperature of contacts
The contacts of the automated coupler have a temperature rise depending on the charging current (rated
continuous current or intermitted current). This temperature rise shall not have any damaging influence on
materials or devices in the surrounding of the automated coupler. These materials or devices require a
maximum temperature of 90 °C according to ISO 17409.
Compliance is checked by test in Clause 8, Table 4.
4.2 Signals
The minimum signals required are the status (the position) of the ACD. All other signalling necessary for
pairing or charging are described in IEC 61851-23-1:— or in ISO 15118.
ACD is in home position
ACD has reached working position (see annexes for specific implementation).
The home position signal is safety relevant.
There shall be a timeout if ACD is moved but the working position has not been reached in a specific time
frame. This information shall be verified by overall system electric vehicle (EV) EVSE, not by the ACD.
5 Safety requirements
5.1 EN 61140
In case of blocking contaminants, the ACD might not reach the home position. There shall be an installed
system that monitors the ACD to reach the home position. This shall be realized by the ACD itself and
communicated to the overall system (EV or EVSE).
NOTE For reaction of this missing home position signal, refer to IEC 61851-23-1:— , CC.5.201, KK.5.201 or
ISO 17409.
5.2 Contact sequence
According to IEC 61851-23-1:— , the connection and disconnection of the ACD shall be done without
current. It is not necessary to have a contact sequence because no dangerous voltage is present.
NOTE Under emergency situation without a first disconnecting CP or PE, arcing cannot be avoided. It is proposed
to have a first disconnecting CP/PE or a guaranteed arc resistive system, so that no danger situation due to that arc can
occur (f. e. fire). Scope is safety and not abrasion.
5.3 Return to home position
In case of an intentional or unintentional loss of supply power for the actuator of the ACD, the ACD shall
return to its home position. For details refer to IEC 61851-23-1:— , Clause 201.3 “Loss of power”
Compliance is checked by test in Clause 8, Table 1 Test Number B3.

6.2 Specific mechanical requirements for busses
Distinction shall be made with regards to the several vehicle dimensions, for instance double/single deck
busses, resulting in several distances between the ACD and the ACD counterpart.
For the position of ACD or the ACD counterpart on the vehicle the reference point is centred over axle A.
Axle A is defined as the first front axle in regard of the driving direction of the vehicle.
This is the reference point for the parking tolerances during charging: x-centre, y-centre, z-centre of axle A

Figure 2 — Location of a Contact System and Positioning Tolerances
6.3.2 Minimum normative requirement for parking
The minimal positioning tolerances that have to be compensated while positioning the vehicle for charging,
are in X- and Y- directions and, for positioning angle, between vehicle and curb:
X at least ± 200 mm (∆x)
Y at least ± 200 mm (∆y), Y at least 0 to + 200 mm for Annex C
Angle between vehicle and curb (Φx) up to ± 2°
Being connected and the vehicle being immobilized, the ACD shall also deal with tolerances of the vehicle
caused by dynamic movements due to kneeling, wind and passenger on and off, and has to avoid losing
contact.
The minimum dynamic tolerance dY = 110 mm for a 3,1 m vehicle height and 2° kneeling (Φz)
The minimum dynamic tolerance dX = 70 mm for back to front kneeling
The minimum dynamic tolerance dZ = ± 70 mm due to air suspension.
The minimum dynamic tolerance dZ = + 0/ −87 mm for 2 500 mm vehicle width due to 2° kneeling (Φz).
If any of above required tolerances are exceeded in service by accidence, no dangerous or damaging
situation shall occur. This can be done by physical limits, as for instance, curbs or sensors detecting the right
position.
NOTE 1 Kneeling is considered only to one side.
NOTE 2 Considering his requirements, the operator can require increased tolerance values if necessary.
NOTE 3 Besides public bus transports and specifically for autonomous vehicle or autonomous vehicle parking, e.g.
automated driven bus depots, smaller tolerances can be agreed between contracting parties.
The physical dimensions of the ACD shall be considered for the dimensions of the vehicle and national or
city regulations for minimum clearance in street traffic. A total load inclusive the force of the contact pressure
shall be considered for the fixing points.
7 Environmental requirements
7.1 Degree of pollution
ACD which are IPXXB when mated shall be designed for pollution degree 3 according to EN 60664-1.
ACD which are IP00 when mated shall be designed for pollution degree PD4 according to railway standard
EN 50124-1.
For covered or cleaned contacts, the normative described reduction of the creepage and air gap distance
can be used.
NOTE Special pollutions such as leaves, branches etc. can be present and require regular cleaning of the interface.
The cleaning schedule of the automated coupler can be agreed between the operator and the manufacturer of the ACD
as its operation is highly dependent on the rate of pollution.
7.2 Overvoltage category
The over voltage category for the ACD shall be equal or higher than required in IEC 61851-23-1:— and in
ISO 17409.
According to IEC 61851-23-1:— , Clause 12.7.101 Suppression of overvoltage (insulation coordination), the
DC EV charging station shall reduce overvoltage between DC ± and protective conductor to 2 500 V.
NOTE This document applies to EN IEC 61851-1 in regard of altitudes up to 2 000 m.
7.3 Ambient or operation temperature
According to EN IEC 61851-1:2019, Clause 11.8.2, an ambient temperature of −25/+40 °C shall be
considered.
NOTE In some countries, other requirements could apply, for example. −35 °C or +50 °C
Consideration shall be given that due to continuous intense sunshine, the surface of the bus could get hotter
and this can have an impact to the ACD.
7.4 Noise
Noise in regard of the ACD can be emitted by moving the ACD from or to home position, in the connecting
moment and also when vehicle is driving by wind effects. Existing national or local requirements shall be
taken into consideration.
EXAMPLE The “TA Laerm” in Germany.
7.5 Wind
The defined parking and contact tolerances shall also apply under the influence of wind forces. Wind forces
have an impact on the vehicle and on the station, in detail for example the support of the ACD. The
manufacturer of the ACD shall provide a datasheet that identifies the forces on the mounting interface of the
ACD and the contact forces in dependence of wind speed. In addition to that, also the worst-case
displacement by wind within the working range of the ACD shall be in that datasheet.
The responsibility of safe operation under all wind circumstances shall lie at the system integrator.
8 Test specification and procedure
The following Tables 1 to 6 contain required tests for type testing and Routine Testing. The tables show
testing standards and requirements for testing automated coupler. These tests are under respect to cover
both cases, that automated coupler are from the same or from different manufacturers.
Critical system limits are characterized by current capacity testing, ensuring the system stays within it
temperature limits and the system sustainability. Before doing the contact quality tests, Table 4 and following,
during heat run test in Table 3 has to verify the system limits for temperature, contact resistance and contact
voltage drop. These limits shall be used for the following tests.
An ACD shall be tested with a standardized fixed ACD counterpart that is defined in the appropriate annex.
A fixed ACD counterpart shall be tested with a standardized ACD that is defined in the appropriate annex.
