Charge the vehicle

Note: The vehicle to be charged must be parked, switched off and the parking brake engaged.
Switch on:
After installing and checking the charging station, press the toggle lever of the circuit breaker in the input terminal box of the charging station upwards to establish the power supply.
The power LED lights up and the charging station switches to standby mode.

1. Remove the type 2 plug from the charging plug holder (CT) and connect it to the vehicle‘s charging port. Please ensure that the vehicle is prepared and set for charging. If you have purchased the charging station as a socket variant (ST), first connect your Type 2 charging cable to the Type 2 socket of the charging station, and then to the charging port of your electric vehicle.
2. The charging process starts when a pre-configured RFID card touches the designated area for the RFID application. Also, the charging process can be stopped by touching the area with the RFID card. 3.
3. After charging is complete, remove the Type 2 plug from the vehicle‘s charging port. Insert the type 2 plug into the charging plug holder (CT). If you have purchased the charging station as a socket variant (ST), put the protective cap back on type 2 charging plug. If you cannot pull out the plug, press the unlock button of the vehicle or key.
4. Emergency stop button Press this button to stop the charging process immediately.

Communication
The charging station has the following interfaces for communication: Wi-Fi, Ethernet, and RS-485.
If the charging station is connected to an internet connection via the Wi-Fi or Ethernet interface, the charging station can be connected to a backend for the management of charging stations vie OCPP (Open Charge Point Protocol). Furthermore, it is possible to control the charging station via ModBus TCP.. The charging station can be programmed, controlled, and monitored via RS-485.

WiFi
Attention: An app for operation is not available.

1. Prepare a 2.4 GHz WiFi router and an Android or iPhone smartphone. Make sure that the charging station and the smartphone are in the same WiFi range.
2. Turn on the Wi-Fi router, and make sure that the router can connect to the Internet. 3.
3. Turn on the smartphone‘s WiFi, connect the smartphone to the router via WiFi, and make sure that the terminal can access the Internet via the router.
4. Install the „esp touch“ APP on your smartphone.

https://github.com/EspressifApp/EsptouchForAndroid/releases/latest

Open the EspTouch app, select „EspTouch“ (not „EspTouch V2“) from the list and grant the app the location authorization.
Now enter the password for the currently connected WiFi network and press „Confirm“ or „Start“ to perform the WiFi configuration.

Press and rotate to reset the emergency stop button three times in succession until the four indicator lights illuminate in a cycle corresponding to the running lamp mode. At  the same time, the LCD screen changes to the WLAN configuration page. Click the „CONFIRM“ button of the APP on the smartphone (Fig.1).
When all the indicator lights flash once in a second, it indicates that the charging station‘s Wi-Fi configuration is completed. At the same time, the LCD screen will display „Successful“ and the name and password of the WLAN SSID (Fig.2).
Note: If the configuration fails, please set the „Multicast“ option in the „EspTouch“ app and repeat the process.

Note: The charging station supports only 2.4GHz wireless networks. Please make sure that your Wi-Fi network operates in the 2.4GHz band.
Note: The IP address of the charging station is negotiated via DHCP. A manual setting is not possible.

RJ-45 connection
The charging station has an RJ-45 connector that can be used for Ethernet and RS-485. Note the pinout for the RJ-45 connector below. Open the cap of the RJ-45 connector and plug in a CAT5e cable or better.

Pinout:

Note: A waterproof housing for an RJ-45 cable is optionally available.
Note: The IP address of the charging station is negotiated via DHCP. A manual setting is not possible.

RFID cards

The charging station is supplied with two RFID cards for offline mode with which charging processes can be started and stopped.
RFID cards for online mode with an OCPP backend are optionally available and have an identification number printed on the card, which must be registered in the OCPP  backend. RFID cards for online mode can be personalized by the unique identification number.
Programming of RFID cards (Offline mode)
To program additional RFID cards for offline mode, proceed as follows.

1. Switch on the charging station and disconnect the cable from the vehicle.
2. Press the emergency stop button.
3. Hold the new RFID card (offline mode) against the RFID reader for at least 10 seconds.
   The new RFID card is now programmed for the EV charging station.

Change charging mode

By default, the charging process is controlled with RFID cards (see section Charging the vehicle).
To start the charging process directly after inserting the type 2 plug, the charging mode of the charging station must be changed. Proceed as follows:

1. Switch on the charging station and disconnect the cable from the vehicle.
2. Hold the programmed RFID card against the RFID reader for at least 10 seconds.
   Switching the charging mode is signaled by the flashing or solid illumination of the Charging (orange) and Fault (red) LEDs.

Emergency stop button
Only press the emergency stop button during a charging process in an emergency. Charging will stop immediately.
Note: Do not press the emergency stop button to end a normal charging process.

Connect with an OCPP backend

The charging station supports OCPP (Open Charge Point Protocol) JSON 1.6 for communication between charging stations and a central management system (backend).
Before using OCPP, the endpoint URL must be programmed into the charging station.
To do this, please send us the endpoint
URL to be programmed, as well as the serial number of the charging station, which you will find in the display of the charging station, by email to ocpp@em2go.de.
Note: The endpoint URL must start with <ws://> or <wss://>. It may take up to 24 hours for the endpoint URL to be programmed into the charging station and for the charging station to connect to the central management system. Make sure that the charging station is switched on and connected to the Internet during this time.
RS-485
The charging station can be externally programmed, controlled, and monitored via RS-485 using AT commands. For the assignment, see the section RJ-45 connection. All commands are terminated with (carriage return).
Note: For the connection via RS-485, bias and terminating resistors may be required depending on the cable length. These are not necessary for short cable lengths.
If there are high ground potential differences between the charging station and the RS-485 transmitter, it is recommended to use a ground cable.

Commands are sent in the format AT+ or AT+=.
For each command received, the charging station sends a response.
