1 Properties of the charging controller

The EV Charge Control charging controller is used to control and monitor the charging of
electric vehicles on the 3-phase AC power grid in mode 3 according to IEC 61851-1. It is
integrated into a defined charging infrastructure which is permanently connected to the
power grid.

The charging controller is designed to control the switching element which is used to estab­lish the connection between the power grid and the electric vehicle. It has a communication
interface via which status data and control signals can be read and written.

The charging controller monitors the Control Pilot and Proximity Plug signals.

The Control Pilot (CP) has the following functions, for example:
– Detection of the protective conductor connection
– Transmission and specification of the vehicle status (vehicle connected, vehicle ready

for charging in various stages, error)

– Transfer of information regarding the maximum available charging current to the vehi-

cle via a PWM signal

The charging controller detects the inserted plug and the current carrying capacity of the
plug and cable via the Proximity Plug signal (PX). This is achieved by means of the resis­tor coding in the plug.

The charging plug lock in the charging station can be activated or deactivated according to
the status via the charging controller.

As an option, the charging process can also be influenced and monitored via the existing
communication interface.

tuators
– Optional locking confirmation and external release as a switching requirement
– Integration into your charging infrastructure via Ethernet interface (Modbus TCP)
– Charging process enabling, status requests, and dynamic load management via re-

mote access
– Four digital inputs
– Four programmable digital outputs
– Four relay outputs
– Connection of an energy meter via RS-485/Modbus RTU
– Optional monitoring of charging currents

Figure 4-2 Control Pilot wiring

Via the CP signal (Control Pilot), the device specifies the permissible charging current to the
vehicle which is coded as a PWM signal. The vehicle indicates the current vehicle status via
the voltage value Va.

The assignment of the permissible charging current value to the pulse width of the PWM sig­nal and the assignment of the voltage value to the vehicle states is defined in IEC 61851-1
(see table in “Typical charging sequence” on page 25).

R2 in vehicle detected.

The voltage value at CP is the result of the series connection of re­sistor R1 in the charging controller, diode D in the vehicle, and re­sistor R2 in the vehicle at 12 V.

In status B, the oscillator with pulse width modulation (PWM) is
switched on. The pulse width codes the permissible charging cur­rent that the vehicle may take from the charging infrastructure.

The coding is shown in the table below.

B1 (9 V DC): EVSE not ready yet

B2 (9 V PWM): EVSE ready

C Charging without ventila-

tion

D Charging with ventilation

If the vehicle has detected the PWM signal, it connects another re­sistor R3 parallel to R2 via switch S2. The resulting voltage value is
6 V (ventilation not required) or 3 V (ventilation required).

6 V or 3 V

The charging controller connects the mains voltage to the vehicle
via a contactor and charging cable. The charging process begins.

B Charging completed The vehicle disconnects resistor R3 again via S2.

9 V

The charging controller disconnects the contactor again and with it
the voltage from the charging cable.

Conversely, the charging controller can also indicate to the vehicle
that the charging process should be completed by switching off the
PWM signal.

If the connected vehicle switches from status B1 (9 V DC) to B2 (9 V PWM) and the vehicle
does not enter status C or D within 30 seconds, the charging controller simulates the dis­connection of the vehicle from the charging station.

The CP signal is set to -12 V DC for 3 seconds. It then switches back to the PWM signal.

This process is only performed once.

5 Wiring of the inputs and outputs

The circuits with lamps and LEDs are only examples. You can also connect other loads
(e.g., optocouplers, relays or digital inputs of a controller).

5.1 Outputs

In status 0, the outputs are connected to GND and in status 1 they are connected to voltage
input 24Va. A power supply of 7.5 V to 30 V DC can be applied at voltage input 24Va.

The maximum current carrying capacity of each switching transistor is 600 mA. The external
power supply must be adjusted to the connected power.

NOTE: Transistor damage

A supply voltage must never be connected to the outputs, as one of the transistors is con­trolled at all times and the transistors would be destroyed as a result.

The wiring of the inputs is just an example. The inputs with switches can be supplied by the
internal voltage source as well as by an external 24 V voltage source which uses GND as
the common reference point. The inputs can also be controlled by an external higher-level
controller with 24 V outputs. Here too GND is the common reference point.

The current carrying capacity of the cable and the plugs is determined via the Proximity Plug
and the appropriate resistance circuit in the plug (see “Proximity Plug wiring” on page 21).

If the PRESET CHARGE CURRENT rotary switch is set to a higher current than the Prox­imity Plug is able to detect, the proximity value limits the current so that the cable or the plugs
cannot be overloaded.

The measured values that are relevant for the charging process are cyclically read by the
charging controller and displayed in the web interface. In addition, they are provided in the
Modbus TCP registers for reading via the Ethernet interface.

Overcurrent Detection Monitoring of charging currents

– “enabled”: the charging controller compares the measured charging currents with the

maximum permissible charging currents specified by the PWM signal on the
Control Pilot.

In the event of an overcurrent of 10% ... 20%, the charging process is aborted after
100 s.

In the event of an overcurrent > 20%, it is switched off after 10 s. The charging con­troller enters an error state, the reset condition is status A.

– “disabled”: no monitoring of charging currents.

Contactor Monitoring With this function, it is possible to check whether the load contactor switched the input free

of voltage after the end of the charging process. If an error is detected, the charging control
goes to error status. The error status can only be canceled by resetting the charging con­troller.

The following configurations are possible:
– “disabled”: the load contactor is not checked.
– “Voltage Measurement”: By means of an attached measuring device, it is possible to

measure the voltage at the charging station output. In order to use this configuration,
the dynamic response of the connected meter must be known. The charging control­ler evaluates the voltage that is read after four polling cycles (“Polling cycle” parame­ter).

– “Aux. Contact NO”/”Aux. Contact NC”: The charging controller evaluates the N/O or

N/C auxiliary contacts of the load contactor. The evaluation takes place 500 ms after
the load contactor is switched off. The length of time can be adjusted using the Mod­bus register 519.

Address: address of the corresponding measured value in the device in decimal notation
Number Registers (0-2): number of data words the measured value in the meter is pro-

vided with. If “0” is entered here, the corresponding value is not read. This is necessary if
the meter does not provide the corresponding values. Meters that code measured values
in more than two data words cannot be read with the charging controller.

Unit/Value: conversion factor for read measured values for display in the web interface.
Depending on the manufacturer type, the measured values on the meters are provided

with different bit values.
This factor is used to adapt to the specified units (V, A, W, kWh, Hz) for display in the web

interface.
The measured values are stored independently of this value in the Modbus registers of the

charging controller, the data is stored as raw values here. When starting up a new meter
for the first time with the charging controller, we recommend carrying out a plausibility
check for the displayed measured values and adapting the conversion factors, if neces­sary.

Reset 1 Address/Value and
Reset 2 Address/Value

Certain measured values can be reset in the meter by writing defined values (max. 2 data
word long) to the specified address area. For example, with the EEM-MA250, writing the
value 1 to address 1024 resets the maximum value of currents I1 - I3. The charging con­troller automatically writes this value after the charging process has been completed
(State A). If the value 0 is entered for number registers (0-2), no values are reset.

9 Modbus description

You can access the device registers via Modbus. The device operates as a Modbus slave
using address 180. It waits for incoming Modbus/TCP requests at port 502.

9.1 Register types

Modbus supports four register types which are used as follows.
Table 9-1 Modbus register

Modbus register type Value Access

Input 16 bit Read
Discrete 1 bit Read
Holding 16 bit Read/write
Coils 1 bit Read/write

You can combine several “Input” and “Holding” registers in order to transmit 32-bit data.
Little Endian format is used to code this data, i.e., the word with the least significant ele­ment is listed first.
