Changelog BETA-Test

Major changes to FENECON Online Monitoring — E-Mobility

Dear Customer,

Thank you very much for your interest in participating in our BETA test.

The following guide explains the basic changes to FENECON Online Monitoring.

Further down on this page, you’ll find a changelog that explains the new features added at regular intervals.

Flat widgets become chips

In this approach, flat widgets are replaced by chips that can be tapped or clicked to create a menu structure.
The main window on your screen displays the contents of the selected chip.
In addition to viewing relevant information about your system, you can also configure settings in the main window.
Depending on the chip you select, you will receive new chips until you reach the endpoint of the menu or menu branch.
You can use the breadcrumb menu to navigate back, either step by step or directly to the start of your FENECON Online Monitoring (house icon).

To improve the user-friendliness of our applications, we take a "mobile-first" approach to development.

The user interface is not yet the final version; it is still under development. As a result, changes may occur in the layout of the chips and the overall design.

Mobile View

Table 1. Mobile View
Mobile View	Explanation
	Swipe up from the bottom to open the main chip menu. The standard tabs History, Autarky, Self-Consumption, Grid, and Consumption are displayed here, as well as Specific chips for each FEMS App, in this case: two KEBA P40 wall boxes.
	You can navigate back using the breadcrumbs displayed at the top of the chip menu.

The charging modes have been renamed. The functions behind them are similar, but not identical.

Click on the Charging Mode tab to open the following main window, where you can set the Base mode:

Image 1. Overview — Charging Modes

No charging: Completely disables the charging station.

Minimum Charging with PV Surplus: The Minimal Charging with PV Surplus mode guarantees that the vehicle is charged to the minimum level. If there is sufficient PV surplus, it is used. If there is no PV surplus, the vehicle is charged using grid withdrawal up to the minimum charging power.
PV surplus: In PV surplus mode (formerly: Automatic), the EV’s charging is dynamically adjusted to the excess electrical energy (e. g., PV surplus). In addition, the Phase Switching chip allows you to switch between 1-phase and 3-phase charging.
Fast Charging: In Fast Charging mode (formerly: manual), the vehicle charges as quickly as possible—depending on whether the phase switching setting is set to 3-phase or 1-phase. If there is sufficient excess PV power, it is used and combined with grid withdrawal.

Click the Schedule tab to open the following main window, where you can set an Active Mode:

Image 2. Overview — Schedule

This main window displays your custom tasks (schedule). If you already have a task in the list, you can EDIT it to, e. g. adjust the time period or the charging mode during that time period.

Click <span style="color:#D01C1F">DELETE</span> to remove the task.

Use ACCEPT to save your changes to the task.

If the "PV" mode is selected on your charging station, you can manually switch from 1-phase to 3-phase charging using the Phase Switching chip:

Tap or click the chip to access the following main view:

Use case

One scenario would be to use the limited PV production to charge the vehicle anyway by manually switching to single-phase charging.

Switching during charging:
When manually switching from single-phase to three-phase and vice versa, the hardware undergoes a 30-second switchover process each time.

Please wait while this switch is in progress.
During these 30 seconds, the charging power is reduced to 0 kW, and then the switchover occurs.

When switching phases, vehicles behave differently depending on the model.
Your vehicle must support phase shifting.
