Pushing the [Open previous configuration] button will load the previous configuration into the current view, allowing you to easily compare settings between firmware updates. You can press the [Save] button to apply the displayed previous configuration.
User Manual User Guide 3.1.2 OCPP Configuration As an alternative to the web interface, the vSECC can also be configured by using a CSMS. To initially connect to a CSMS, you must specify the CSMS’s URI in the vSECC’s configuration using the web interface. The corresponding variable is called ”BaseUri” and can be found inside the ”ChargingStation” section as seen in Figure 17.
User Manual User Guide Inside Vector’s CSMS solution vCharM for example, the vSECC’s variables are presented as shown in Figure 18. The information about the available variables is gathered automatically when the vSECC establishes its connection. Changes to any variables are sent to the vSECC, where they are validated and then applied to its configuration. Figure 18: vCharM Charging Station Configuration © Vector Informatik GmbH Version 1.2.
User Manual User Guide 3.2 Installing Root Certificate Authorities (CAs) When connecting to a CSMS using a secured TLS connection, the vSECC uses its installed root certificate authorities (Root-CAs) for verifying the server’s certificate chain. The vSECC already comes with the mozilla root certificate store pre-installed. Additional Root-CAs can be installed either by using the web interface or via OCPP.
User Manual User Guide 3.3 Downloading Log Files To assist technical support, the vSECC application’s log files can be downloaded from the vSECC either by using the web interface or via OCPP. To download log files using the web interface, put the vSECC into maintenance mode as described in chapter 3.1.1. Head over to the ”Log Files” section shown in Figure 20.

Possible values are: DC_extended: DC charging using the extended pins of an IEC 62196-3 Configuration EE or Configuration FF connector.
User Manual PowerElectronics/ Uri User Guide The URI to communicate with the power electronics. If the ”Type” variable is set to ”Simulation”, the default value is sufficient. When using real power electronics, the URI must be set to the websocket server’s address. Default: http://localhost:8080/PowerElectronics © Vector Informatik GmbH Version 1.2.
User Manual User Guide 3.6 EVSE Topology The configuration’s structure is based on OCPP’s 3-tier model which is also used by vCharM. This model describes the charging infrastructure on a logical level, consisting of three elements: ”Charging Station”, ”EVSE” and ”Connector”. Charging Station The term charging station describes a physical system where an EV can be charged. Each vSECC unit corresponds to one charging station.
User Manual User Guide Connector The term connector describes an electrical outlet on a charging station. It is connected to a single EVSE. An EVSE can have multiple connectors attached to it, e.g. one CCS and one CHAdeMO compliant outlet. However, an EVSE will always use only one of its connectors exclusively. The complete 3-tier model is visualized in Figure 25. Figure 25: Overview according to OCPP 2.0: Part 1 © Vector Informatik GmbH Version 1.2.
