Introduction

This document is a guide for service technicians to configure charge station LS3 from Garo AB. The charge controller, CSR100, can be configured as a public or private charge

station with or without connection to our cloud based web portal.

Contact Garo AB prior to site installation. We will provide you with the information required for connecting your site to your company Charge Portal.

Appropriate technical knowledge and certification for work with electrical installations and maintenance work is required to prevent danger to persons or property.

Accessing the CCU web configuration

Configuration using the web-interface is available from CCU version 2.7.2 and later.

Install correct driver Linux.inf for USB Ethernet/RNDIS Gadget (Tested in Windows 7). Local administrator privilege is required to install the driver. Most Linux system has

native support for RNDIS Gadget.

Power up the CCU board.

Attach a USB cable to the mini-B USB connector between the CCU board and a PC according to Fel! Hittar inte referenskälla..

Use a modern web browser to and navigate to 192.168.7.2

User: ccu

Password: ccu

Note that webinterface respons may sometimes be slow due to limited system resources on the microcontroller.

CCU Configuration

Settings related to a specific installation are stored in chargemanager.ini. Garo may prepare a configuration file that can be uploaded using System-> CCU Configuration-

>Upload CM configuration but is not unusual that this configuration is made by a service technician during site installation. This configuration requires knowledge about

backend setting, communication interfaces and other site related information.

To manually edit the site configuration press “Edit the current chargemanager.ini”.

Site configuration is divided in five different sections. In Figure 3 below the tab for “General configuration” is active. After completing each configuration page press “Save”

button to activate the changes or press “Reset” to restore default values.

Most settings have build-in tool tips, an information pop-up window, that is accessed by holding the mouse pointer over the parameter.

1. Charging Enabled (Yes/No) set option to “Yes” to enable charging. If backend is available it will still connect to it.

2. Fuse Rating (6, 10, 16, 32, 63A) specifies the main fuse for the chargestation.

3. Enable Nanogrid Load Balancing (Yes/No). Select “Yes” for an installation with several charge stations that share a limited amount of current. Additional

configuration and measurements are normally required. If unsure select “No” .

Backend

Figure 4 Backend Configuration

1. System Identity This name needs to be the same as nodeUuid in Charge Portal.

2. Communication Protocol

None: Standalone system without internet connection.

OCCP 1.5: Standard protocol supported by many different charge stations. Use this option for all 3G connected systems and for wire connected systems

with a dedicated public IP address.

OCCP 1.5 with CS extensions: Will generate more traffic and is not recommended for 3G installations. Main benefit of the CS extensions is to be able to

use a private IP address and still communicate with Chargestorms ChargePortal .

3. Backend Endpoint Address to the company portal. In Figure 4 company name is demo2, replace “demo2” with your specific portal. For example

http://ikea.oamportal.com/Ocpp/CentralSystemService15 for IKEA portal.

4. Local Proxy (Yes/No) Select “No”

5. Online Timeout (Minutes) Reboot timeout value for a system configured with a backend connection. If the system can’t access the portal within this time

the CCU will reboot. Note that the CCU will not reboot during an active charge session. Default configuration is 24h (1440 minutes).

Interfaces

The most common interface configurations are described below:

Connection to backend using Ethernet (Static IP)

Connection to backend using Ethernet (IP from DHCP)

Connection to backend using Ethernet (Static IP, poor router)

Connection to backend using WiFi (IP from DHCP or static)

Connection to backend using 3G modem

Ethernet

1. Select wired connection

2. Select manual and specify a unique

private IP address and correct netmask. This

information is given by the network

administrator on the installation site.

3. Use default settings:

Speed: 100MBit

Autonegotiation=true

Duplex=true (Full duplex)

4. Use default settings:

Speed: 100MBit

Autonegotiation=true

Duplex=true (Full duplex)


2. Configure for DHCP or static. Static is used

in Figure 7.

3. Use settings:

Speed: 10MBit

Autonegotiation = false

Duplex = half

Note: Only try this if you have problems

with the Ethernet connection.

WiFi

Figure 8 Connection to backend using WiFi (Static or DHCP)

Note

Only WPA2 is used for encryption and needs to be supported by the access point.

Use Alfa network AWUS036EW 802.11 b/g WLAN USB adapter.

1. Select WiFi connection

2. Configure for DHCP and leave IP address

and netmask blank or configure for manual

(static) and specify IP address and netmask.

3. Use settings:

Mode: Client

SSID: <Name of network>

Passphrase: <Password>

CCU Diagnostic’s menu

A file containing logs and other diagnostic information can be downloaded by pressing “Retrieve the diagnostics file”. This information should be sent to Garo for further

investigations.

CCU Reboot and FW upgrade

Firmware can be upgraded in two ways: Either by placing an upgrade.bin file on a USB stick, attach it to the CCU board and press “Upgrade” (1 in Figure 10) or by locating

the file on the harddrive with “Browse…” (2 in Figure 10) and press “Upgrade” (3 in Figure 10).

It is also possible to reboot the CCU pressing “Reboot” (4 in Figure 10)

CCU Status Information

Information page for hardware, connection and outlet information. It is also possible to unlock a locked SIM card.

CCU Tag Administration

Write tag number in decimal or hexadecimal (starting with 0x to indicate a hexadecimal number) and press “Add tag” to add a specific tag to the local tag database. This list

of valid tags will be check before checking against RFID tags on the portal. This list is useful for systems that do not have a backend connection and to verify which portal

tags that are locally cache for faster authorization.

Backend Configuration Troubleshooting

Pay attention to the LED strips of the unit during start-up. They can give some information on what is going on. It is also useful to look at the CCU Status information.

Alternating flashing red lights

First attempt to connect to backend failed. This is common for 3G connections.

Alternating flashing blue lights

Indicates first successful connection to backend.
