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
1
and specific requirements. This document is expected to be read in conjunction with IEC 61851-23-1:— .

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,
1
for circuits specified in IEC 61851-23-1:— .
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.

SIST EN 50696:2021
EN 50696:2021 (E)
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
1
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
2
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.
2
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
1
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.

EN 50696:2021 (E)
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).
1
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
1
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
1
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.

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.

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.
The present document contains requirements for all type of ACDs. Its annexes describe specific
implementations and specific requirements. This document have to be read in conjunction with
prEN 61851-23-1:2018.

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 prEN 61851-23-1:2018.
The ACDs covered by this document are used only in charging mode 4, according to prEN 61851-23-1:2018,
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 parameter 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 f. i. a robotic arm.
This document does not cover all safety aspects related to maintenance.

4 Electrical Requirements
4.1 Voltage and current requirements
4.1.1 Number of contacts
For systems described in prEN 61851-23-1:2018, Annex AA, BB and CC:
Four contacts: DC+, DC-, PE and CP (prEN 61851-23-1:2018 AA.11, prEN 61851-23-1:2018 BB.11 and
prEN 61851-23-1:2018 CC.11)
For systems described in prEN 61851-23-1:2018 Annex KK:
three contacts: DC+, DC-, PE (prEN 61851-23-1:2018 KK.11)
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 to exceed the levels indicated in prEN 61851-23-1:2018.
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 standard.
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 standard. 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
The short-circuit current is specified in ISO 17409:2015, 6.2.4.2 for system C and shall be taken into
consideration also for ACD charging. The short circuit current of the electric vehicle supply equipment
(EVSE) is defined in prEN 61851-23-1:2018, Annex CC 6.5 and Annex KK 6.5
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.

NOTE 1: 12 000 000A 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 17409:2015,
6.2.4.2 shall not lead to damages or dangerous situations in regard of the Lorenz force.
NOTE 2 This limit is given in ISO 17409 and in prEN 61851-23-1:2018.
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 chapter 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 prEN 61851-23-1:2018 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 may 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 prEN 61851-23-1:2018, CC.4.201 or ISO 17409.
5.2 Contact sequence
According to prEN 61851-23-1:2018, 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 suggested 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 prEN 61851-23-1:2018, Clause 103.3 “Loss of power”

6 Mechanical Requirements
6.1 Grid of parallels and meridians
Figure 1 — Grid of parallels and meridians according ISO 8855
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.
This is the reference point for the parking tolerances during charging: x-centre, y-centre, z-centre of axle A

6.3 Tolerances of parking position
6.3.1 General
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- direction and for positioning angle between vehicle and curb:
X at least ± 200mm (∆x)
Y at least ± 200mm(∆y), Y at least 0 to +200mm 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 = 110mm for a 3.1m vehicle height and 2° kneeling (Φz)
The minimum dynamic tolerance dX = 70mm for back to front kneeling
The minimum dynamic tolerance dZ = +-70mm due to air suspension.
The minimum dynamic tolerance dZ = +0/ −87mm for 2500mm vehicle width due to 2° kneeling (Φz).

oSIST prEN 50696:2020
prEN 50696:2020 (E)
If any of above required tolerances are exceeded in service by incidence or 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.
