System Overview
8 / 156
2 System Overview
Charging multiple electric vehicles simultaneously, may exceed the capacity of the existing power connec-
tion. To avoid an overload, simultaneous charging of multiple vehicles or at least the capacity of the individu-
al vehicles must be managed and limited. This requires a solution that protects the grid from overload using
smart load balancing and load scheduling and provides an efficient energy profile for each individual EV
(electric vehicle).
The communication between electric vehicles (EV) and the KeContact M10 works according to IEC 61851-1
Mode 3 or, if supported by the EV, ISO 15118 high-level protocol.

3 System configuration information
3.1 General statement
Purpose of the load management software
Cost-effective allocation of the available or allowed capacity (e.g. charging at night with low rates)
Load balancing
Optimized power distribution over several vehicles
Support for different communication protocols (low level IEC 61851-1, high-level ISO 15118)
Schematic overview (load management)
Fleet solution
The KeContact M10 is the server for a group of Charging stations (KeContact P20 Wallboxes) with a com-
mon power line. KeContact M10 is the logical Charge Point.
After a power failure or the loss of the communication connection, an automatic restart is performed. After-
wards the running charging sessions are resumed.
Plug & Charge with ISO 15118
The ISO 15118 protocol allows an intelligent charging of an Electric Vehicle. The charging station informs the
vehicle when and at which price a certain energy amount is available. This data, the current battery level and
the programmed finishing time is the basis for the vehicle to determine a cost optimized charging procedure.
Basis functionality for charging
Vehicles that offer only a functionality for charging according IEC 61851-1 are also supported. The authoriza-
tion for charging can be carried out with a chip card (RFID).

System configuration information
12 / 156
Load Management
The Load Management of the KeContact M10 distributes the available power line capacity to the connected
vehicles.
“First come, first serve” mode
The vehicle gets the information of the available energy amount till the scheduled departure of the car via an
ISO 15118 message. With this information, the vehicle calculates its charging procedure and reports it to the
KeContact M10. The required energy amount will be reserved and is not available for other vehicles.
"Equal allocation" mode
This mode is used, if the communication with the vehicle is not possible via ISO 15118 protocol. In the case
that there is not enough energy available for all vehicles, all vehicles get the equal amount. If this amount is
too low (below the minimum-current for electric vehicles), the charging of the vehicles will be stopped for a
certain period of time.
A combined mode of both strategies is possible too.
Authorization
The KeContact M10 can manage a „White list“ with authorization codes. Vehicles (Vehicle ID with
ISO 15118) and chip cards (RFID) can be added to this White list.
Counter data
The counter data are not calibrated. It is therefore at the discretion of the operator, whether the data is used
for billing purposes.
3.1.1 Supported communication protocols
The load management software together with the KeContact P20 charging stations supports the exchange of
information according to the following two standards:
Mode 3 Charging
DIN EN 61851-1
Communication via DIN EN-61851-1 is a low level communication,
between Charge Point and Electric Vehicle.
The limitation of the maximum possible charge current is done via
the control pilot pin of the charging cable and is determined by the
Wallbox (and the used cable). The Wallbox can regulate the charg-
ing current by changing the PWM signal (Pulse Width Modulation).
ISO Charging
ISO 15118
Communication via ISO 15118 is a high-level communication be-
tween the Charge Point system and the Electric Vehicle using power
line communication (PLC).
Moment, duration and charging current are negotiated between the
KeContact M10 and the Electric Vehicle.
Initial settings must be made for the entire system:
Which communication protocol shall be supported?
only Mode 3 (no high-level negotiation will be used)
only ISO communication (sole Mode 3 Electric Vehicles will not be able to charge)
combined mode charging (both, Mode 3 and ISO communication is a allowed)

System configuration information
13 / 156
3.1.2 Value for limitation of the power grid
A key value for the load management system is the total maximum available current (amps) of the power
grid. This value represents the maximum power which can be supplied from the grid due to wiring and fuses.
Additionally the maximum total current can be reduced in dependence of time and day.
Example:
The total maximum available current of the power supply line is 200 amps. Between 8 o'clock pm and 6
o'clock am there is no reduction. From 6 o'clock am till 8 o'clock pm there is a restriction to reduce the maxi-
mum total current down to 120 amps.
Splitting between Mode 3 charging and ISO charging
The maximum total current for charging vehicles using Mode 3 communication or ISO communication can be
split into two sections. For both groups of vehicles thus the available total current is reserved.
The specified limit is dynamic, so vehicles with a Mode 3 communication can temporarily use free quota from
the ISO range as long as there are free capacities. Vice versa this is not possible.
Example:
80 amps shall be reserved for Mode 3 charging.
120 amps shall be reserved for ISO charging.

System configuration information
14 / 156
3.1.3 Current allocation on multiple vehicles
The allocation of quotas follows the FIFO principle (First-in-First out), the charging current quotas for Mode 3
charging and ISO charging will be considered separately.
Section ISO charging
If the total charging current of the EVs in the ISO charging group exceeds the limit, a new added vehicle (in
the example "ISO4") will not be charged immediately. The vehicle "ISO4" is shifted for a later moment, until
the consumption of the other EVs in the ISO group is going down and a quota is available.
Section Mode 3 charging
If the total charging current of the EVs in the Mode 3 charging group exceeds the limit, a new added vehicle
(in the example “M3-1”) can be charged anyway, if there is a free quota in the ISO charging group. The vehi-
cle “M3-1” will be charged until the ISO quota is needed again. If this happens, the charging current for the
Mode 3 charging vehicles is reduced accordingly. ISO charging vehicles always have higher priority.

System configuration information
15 / 156
3.2 Software architecture
The KeContact M10 system contains the following main software components.
Load Manager:
The load manager has the following responsibilities:
Controls and coordinates charging sessions for several vehicles on the separate charging stations
(PDCs).
Is offering WEB services for the vehicle manager. These services allow the vehicle manager to initi-
ate, start / stop charging sessions and other activities in response to the according requests of an
electric vehicle using high-level communication.
All necessary activities and events that occur on the different charging stations (sockets) are man-
aged and controlled by the socket manager (PDC manager). This way the socket manager assists
the load manager in managing the separate charging sessions.
The load manager gathers the different information of the separate charging sessions, the used
PDCs and the vehicle information and forwards those data to the charge point manager.
A core component of the load manager is the socket manager:
Represents the network of all connected PDCs and their status.
Forwards requests to the addressed PDCs, handles and reports status changes
Vehicle Manager:
The vehicle manager has the following responsibilities:
Handles communication with vehicles using high-level communication (ISO 15118). Issues requests
to the charge point manager and web service requests to the load manager in order to fulfil loading
requests received by vehicles.
Establishes und closes secure communication sessions with vehicles.
Charge Point Manager:
The charge point manager has the following responsibilities:
Manages the available power and assigns it to the PDCs (for Mode 3 charging) and to electric vehi-
cles (for charging controlled by high-level communication).
Manages the HTML user interface for monitoring (status and current transactions) and entry of con-
figuration data. Access to the monitoring pages of the charge point manager is allowed to anybody
with proper network access.
Pages for configuration and system changes require a login.
User Interface:
The operator of the system connects with a web browser to the KeContact M10.

4 Hardware installation
4.1 Common power line
The Wallboxes must be connected to one common power line with protective devices, otherwise the KeCon-
tact M10 is not able to perform a correct load management according to the maximum available current.
A clustering of Wallboxes is not permitted!
Be aware that each wallbox has to be secured by an individual RCD. Please see the “KeContact
P20 Installation manual” for further details about installation.
Common power line –schematic overview
DO NOT USE multiple power lines!

Hardware installation

4.2 Provisions for flawless ISO 15118 communication
Installation recommendations when using more than one PLC Wallboxes.
PLC blocking filters:
If the vehicles are using ISO 15118 without SLAC mechanism (automatic pairing function), it is recommend-
ed to install PLC blocking filters in the supply line of the PLC Wallboxes. This avoids communication trouble
when charging two vehicles at the same time.
Suitable PLC blocking filters can be ordered from KEBA.
Network Membership Key’s (NMKs)
If the NMKs of the vehicles are different, PLC blocking filters are not required!
The NMK of a vehicle can be changed with the “KEBA - EV Connection Assistant” software that
can be downloaded from www.kecontact.com.
Schematic overview
Additional information
With Public NMKs you are able to connect to devices in the whole network supported with PLC modems in
the Wallboxes. Private NMKs are useful to connect to one device specified in the network.

4.3 Ethernet wiring
For details about installing and connecting the components, please refer to the individual compo-
nent manuals (KeContact P20 Installation manual, Installation manual of your Ethernet switch
and patch panel).
Use the LSA+® terminal block [ETH1] for the Ethernet connection and NOT the RJ45 port.
In any case the KeContact LAN must be designed as a closed network without direct public access.
Only the KeContact M10 can be connected via the Ethernet port [ETH1] to a public LAN (eg, corporate
network).
The individual Wallboxes are wired to the patch panel using a Cat6 (or higher quality) patch cable.
The connection between Ethernet switch and patch panel is made with standard patch cables (2xRJ45).
