Symphon-E App Multi-Charging Point Management

1. Introduction

Dear customer,

Thank you for choosing the "Symphon-E App Multi-Charging Point Management". You are welcome to send us your suggestions so that we can further improve the quality of our products.

2. Multi-Charging Point Management

From 01/04/2023, the multi-charging point management function will be included from the second charging station or the second charging point. You no longer need to purchase an additional app for this!

Using multi-charging point management, several charging points can be linked and controlled in a cluster. The following functions are available within the cluster:

  • Control algorithm for controlling multiple charging stations (incl. charging points)

  • Avoidance of load peaks at the grid connection point through:

    • targeted discharge of the electricity storage system and

    • dynamic limitation of charging power at the charging stations/charging points according to prioritization

As soon as multi-charging point management has been activated on your system, you will see the following widget in your monitoring.

In Flat widget you can see the number of charging stations or charging points that are taken into account in multi-charging point management (here: 8), as well as the current total charging power in watts (here: approx. 30 kW)

Click on the widget to open the detailed view of the app:

The individual charging stations/charging points are broken down in Detailed view. In the example above, 8 Keba c-series charging stations have been integrated.

The prioritization of the individual charging stations/charging points can be adjusted using the selection elements on the right (see Detailed view — Change prioritization) by selecting them and then moving them in the list. The higher the prioritization of a charging station/charging point, the later it will be down-regulated or the earlier it will be up-regulated again as soon as power is available again.

3. Compliance with the maximum power reference at the grid connection point

This manufacturer’s declaration is applicable to electricity storage systems with the Energiemanagement System.

Using the Symphon-E App Multi-Charging-Point Management ensures that an adjustable total charging power (e. g. 11 kW) is not exceeded for all charging stations.

The manufacturer’s declaration is expressly valid under the following conditions:

  • The Energiemanagement System is online and active at all times.

  • Officially supported charging stations from Heckert Solar/EMS are used.

  • The Energiemanagement System is connected to the charging stations via the customer network at all times.

  • The Energiemanagement System is connected to the grid meter at all times.

  • The Symphon-E App Multi-Charging-Point Management is active at all times.

The FEMS multi-charging point management app regulates the power values within the cluster. In combination with external management systems (such as RFID authorization, billing services, etc.), it may occasionally be necessary to plug in multiple times.
