Connectivity

Introduction

Two versions of VersiCharge are offered with respect to connectivity:

1. Child devices are equipped with Wi-Fi, Ethernet and serial communication to connect the device to the internet or to a parent device for the internet connection.
2. Parent devices also include a 3GM mobile wireless modem. This results in different possible connectivity levels, providing a variety of choices.
   • Level 1 (blue/gray)
   • Connectivity of VersiCharge devices via the Internet with Siemens Device Management and operator backend
   • Level 2 (green)
   • Connectivity between VersiCharge devices
   • Level 3 (yellow)
   • Connectivity with building management

Level 1: Connectivity to the Internet

Connectivity between VersiCharge and the Internet is possible via multiple connection channels and ensures that VersiCharge is connected to the Siemens Device Management:

1. WiFi connection
2. Ethernet connection
3. Mobile wireless connection (only with parent devices)
4. Gateway connection (router or parent devices)

The connection channels differ with respect to installation workload and costs. With sufficient signal strength, connection via WiFi is the simplest way. However, this is not always possible.

Level 2: Connectivity with one another

When using a local Wi-Fi network, we recommended connecting the devices to it, provided signal strength and quality are sufficient. If this is not possible, you can use a parent device as Wi-Fi receiver to transmit the OCPP data via Ethernet or wireless communication.

Note: The Wi-Fi signal strength must be 60 dBm or stronger.

When multiple VersiCharge devices are used, this results in three scenarios that are illustrated in the following figure.

Decision tree for connecting VersiCharge to Siemens Device Management

Child devices are equipped with Wi-Fi, Ethernet and serial communication to connect the device to the internet or to a parent device for the internet connection. The following decision tree supports you in deciding how to connect VersiCharge to the Siemens Device Management.

Note

Without Internet connection, the VersiCharge Wallbox can be used, but without the following features:

• Automatic firmware update
• App use
  • Status display in the VersiCharge app
  • Delay function in the VersiCharge app
• OCPP connection
• Limited remote support

Applications

General information

The decision to connect the charging station to the internet depends mainly on the local conditions. The possibilities are illustrated below based on real applications. The decision on the method of connectivity to the Siemens Device Management should already be made before the installation, because further adjustments later are very difficult. The following list of applications is not exhaustive. A combination of these applications may be possible depending on the situation on location.

Note

• Parent and child devices must have at least firmware V2.111, otherwise call customer service.
• Switch on the commissioning parent device first and then the child devices, otherwise the parent hotspot will not be detected.

Installation in single-family home (garage or carport)

Introduction

As a rule, your own home provides the possibility to ensure connectivity of VersiCharge via your own home network. This requires the strength of the WiFi signal to be sufficient (see Connection via WiFi. You can install up to two VersiCharge devices in a single family home and connect them to your Wi-Fi.

Garage or carport

A smart charging unit for residential use should be connected to the home Wi- Fi network and the Siemens Device Management website to receive the latest updates for the charging unit. Siemens also offers a charging unit for residential use without communication.

There are several conceivable scenarios

• Figure 4-1: A child device that is connected via Wi-Fi signal (see Connection via WiFi or Ethernet (see Connection via Ethernet.

Multi-family homes or condominiums, townhouses and apartments

Here, we are looking at setup scenarios in outdoor areas, multi-story homes, underground parking decks and underground garages without sufficient wireless coverage. You can install commercial VersiCharge charging units in a parking deck or the garage of a multi-family home. The following scenarios are possible for establishing the connectivity of the charging stations:

• Figure 4-5: Parent or child devices that are connected via the Wi-Fi signal of the apartment or the condominium (see Connection via WiFi or via Ethernet (see Connection via Ethernet.

Installation in a company parking deck or parking lot

Introduction

Installation in a company parking deck or parking lot is considerably more challenging because a greater number of charging stations is required and the distances between the individual charging stations are increased. In addition, effects such as blocking by walls significantly influence the options for connection to the Internet.

Installations in a parking deck

When installing VersiCharge devices in a parking deck, the key challenge is signal blocking by the building. There are several possible scenarios for installing a VersiCharge in a parking deck:

• Figure 4-8: If the wireless signal strength in the parking lot is sufficient, a parent device can be installed and connected to the internet via mobile wireless. The parent device supports up to nine commercial child devices via Wi-Fi; these are located at a distance of up to 150 ft (45 meters) (line of sight) from the parent device. Walls or other obstructions reduce the Wi-Fi signal strength; this means you should conduct a location audit to ensure connectivity with the parent device (see Feasibility).

2. Parent device
3. Commercial child devices

• Figure 4-9: If the wireless signal strength in the parking lot is not sufficient, a parent device can be installed and connected to the internet via a copper Ethernet connection. The parent device supports up to nine commercial child devices via Wi-Fi; these are located at a distance of up to 150 ft (45 meters) (line of sight) from the parent device (see Feasibility).

1. Ethernet connection
2. Wi-Fi connection of parent device
3. Commercial child devices

Figure 4-10: If the wireless signal strength in the parking lot is not sufficient, a direct communication network can be set up via Wi-Fi or copper Ethernet. The Wi-Fi method requires a good signal strength at the location of the charging station. Walls or other obstructions reduce the Wi-Fi signal strength; this means you should conduct a location audit to ensure connectivity with the parent device. The standard Ethernet network rules apply to an Ethernet connection to a building hub/switch. The standard copper Ethernet network covers a distance of up to 328 ft (100 meters). (necessary/possible steps: Creating an account in the Siemens Device Management, Connection via WiFi, Connection via Ethernet, AUTOHOTSPOT)

Installation in the parking lot

There are several possible scenarios for installing a VersiCharge in an open area, such as a large company car park:

Figure 4-11: A commercial child device works best in parking lots. It can be connected via Wi-Fi to a parent device with mobile wireless connection. The parent device supports up to nine commercial child devices via Wi-Fi; these are located at a distance of up to 150 ft (45 meters) (line of sight) from the parent device. If there are obstructions, such as trees, posts, or similar, you should check the strength of the Wi-Fi signal to ensure that a good signal strength exists between the parent device and the child devices (see Feasibility)

Connecting the VersiCharge AC charging unit to the Siemens Device

Management cloud

Introduction

The scope of supply of all VersiCharge charging units includes the Siemens Device Management. It offers remote support and automatic firmware upgrades with the option of upgrading your charging units depending on your management requirements. If you want to use this service, you must activate it by creating an account. As soon as you have created the connection for your VersiCharge device(s), you register the device(s) with the Siemens Device Management. For a single VersiCharge charging unit, we recommend using the VersiCharge app on your smartphone. To commission multiple devices, you must use the “VersiCharge Configurator” tool (see Feasibility (Page 27)).

Creating an account in the Siemens Device Management

There are two options for creating an account in the Siemens Device Management.

1. For a single VersiCharge charging unit, we recommend using the VersiCharge app on your smartphone.
2. To commission multiple devices, use the “VersiCharge Configurator” tool. To create the account during commissioning for the end user (see Feasibility).

Selecting VersiCharge in the app

Five different connection types are offered. The preferred version must be selected:

• WiFi
• Ethernet (automatic setup)
• Ethernet (manual setup)
• SIM card (already registered)
• SIM card (not registered)

Additional information is available here (https://support.industry.siemens.com/cs/us/en/ps).

Using the charging station in offline mode

If there is no connectivity, the charging station can also work in offline mode.

Feasibility

Connection via WiFi

The local WiFi signal must have sufficient strength to connect to the Wallbox. If the WiFi signal is lower than -60 dBm, connection via WiFi is not recommended. The WiFi signal strength can be measured on a smartphone using various apps (iOS: Airport1, Android: WiFi analyzer) or using a laptop with a corresponding program (e.g.: WirelessNetView). If this is not the case, the WiFi signal can be boosted using a WiFi repeater. For the connection via WiFi, the desired network is selected and the correct password is entered using the app and registered in Siemens Device Management.

Note: Enable WiFi search in the settings of the app.

Connection via Ethernet

If the WiFi signal is insufficient, VersiCharge can be connected to the Internet via a LAN cable as an alternative. In this case, in addition to the security policies of the network, it must be considered whether the maximum length of 328 ft (100 meters) for an Ethernet connection is exceeded on site. You can find the details on the connection and the available ports in the operating instructions (see SIOS (https://support.industry.siemens.com/cs/de/en/view/109782228)). If it is not possible to connect via Ethernet or WiFi due to the conditions on site, parent devices have the option of connecting via mobile wireless.

Note: Ensure that the Ethernet cable is already connected to the LAN and that an open internet connection exists before you start the device.

Connection via mobile wireless

Connection via mobile wireless is only possible with a parent version and a booked data plan. If the mobile wireless signal is weaker than -90 dBm, a connection via mobile wireless is not recommended. There are a range of smartphone apps for testing the mobile wireless connection. In iOS, this can be done in Field Test Mode with the key combination 3001#12345#, and the value is given under rsrp0. Under Android, the OpenSignal app can be used.

Connection via the WiFi access point of the first Wallbox

Larger installations of two or more VersiCharge devices are configured with the PC tool. In this case, the individual VersiCharge devices are commissioned one after the other via Wi-Fi, Ethernet or mobile wireless connections. More information is available in the PC tool configuration video or in the instruction (see SIOS (https://support.industry.siemens.com/cs/de/de/view/109798469/en)).

Connection to an operator backend system

Introduction

The OCPP parameters are set via the Siemens Device Management. The data stored there is then transferred to the successfully connected and registered charging station.

Integration tests with the backend operator

It is only possible to connect the VersiCharge with operator backends that have already successfully passed integration tests. This is the only way to ensure that connection to the backend system works correctly. In this integration test, the necessary parameters (such as OCPP endpoint) are stored in the Siemens Device Management. Please contact your Siemens contact partner in relation to this.

Assigning VersiCharge to the backend operator

After successful integration tests and successful registration of the VersiCharge in the Siemens Device Management, the serial number of the VersiCharge must be assigned to the certified operator backend. Please contact your Siemens contact partner in relation to this. The options offered by VersiCharge connected to an operator backend depend on the backend provider. The VersiCharge complies with the OCPP standard.

Optional: Replacing the SIM card:

It is possible to replace the SIM card of the VersiCharge. Information on how this works can be found in the enclosed operating instructions. When a non- Siemens SIM card is used, the connection for the Siemens Device Management must be made available so that service and remote updates of the firmware can be enabled. Use of the provider’s own SIM card with VPN is not intended, because no connection to the Siemens Device Management can be established in this case.
