Charge Point & Charging Park Management

Integrate multiple charging stations or an entire charging park intelligently into the FEMS.

Highlight

Automatic Phase Switching

With the FEMS App AC Charging Station, the FEMS automatically switches between single-phase and three-phase charging for selected charging stations — depending on the available charging power.

  • More solar power in your car: Even a small PV surplus is used — single-phase from 1.38 kW instead of three-phase from 4.2 kW only.

  • Less grid consumption: Charging adapts automatically to fluctuating PV generation.

  • No manual switching: The FEMS takes care of the phase switching for you.

Prerequisite: Your vehicle supports dynamic phase switching. In Fast Charging mode, charging always takes place on three phases.

Installation and Configuration Manuals by Charging Station

FEMS App AC Charging Station

By redeeming a license key for the FEMS App AC Charging Station, the FEMS obtains write access to one AC charging station of the following manufacturers/models.

Advantages of the Charging Stations Compared

All supported AC charging stations can be controlled by the FEMS, e.g. for intelligent PV surplus charging. In general, we support Automatic phase switching for all AC charging stations.

  • For automatic phase switching, your vehicle must support dynamic phase switching.

  • The switching times depend on the charging station and its internal logic.

  • The KEBA KeContact P30 (c-series and x-series) additionally require the KeContact S10 Phase Switching Device for phase switching.

Frequently Asked Questions

Planning & Grid

What does e-mobility mean for the grid and for electrical energy storage systems?

As the charging infrastructure for e-mobility continues to expand, Commercial and Industrial systems are gaining in importance.

Every new charging park increases the electricity demand within the power grid. To handle this peak load, each expansion stage could be paired with a corresponding grid extension — meaning significant investment in cables, transformers, and construction work.

Alternatively, the supply line to the parking area can be kept at a reasonable size, with the load peaks buffered by a system. Industrial storage systems with high discharge power and a high C-rate are often the more cost-effective solution while requiring relatively little floor space.

The key here is to combine storage and charging point management within a single energy management system in order to create a holistically optimized solution.

Is a step-by-step setup of a charging park possible?

Yes, a step-by-step setup is possible with a FENECON energy storage system. In most cases, only a few charging points are installed in the first step, but further expansion stages with additional AC chargers — and typically mid-speed DC chargers as well — are expected to follow every few years.

Wallbox & Connection

How do I find the right wallbox for my electric car?

It depends on several parameters:

  • desired charging power: (AC wallbox or DC fast-charging station)
    Important: For charging stations up to 11 kW, the connection conditions must be requested and the grid operator must be notified.
    For 22 kW wallboxes, additional approval from the grid operator is required according to the Federal Network Agency (Bundesnetzagentur). In this case, a three-phase connection is usually required.

  • number of charging points for electric cars to be charged simultaneously. A distinction is made here between single or multi-connector types.

  • connector types, i.e. the connectors of the electric cars (usually Type 2 or CCS in Europe).

  • cable or socket variant (should the cable for the electric car be brought along, or already attached to the wallbox?)

The advantages of the charging stations supported by the FEMS are shown in the charging station comparison.

What do I need to connect charging infrastructure to my FENECON energy storage system?

The wallbox must be compatible with the FENECON energy storage system (see compatible charging stations). In addition, the charging station or wallbox must feature a network interface (Ethernet/Wi-Fi) so it can be integrated into the customer network. The FEMS can then communicate with the charging station via this network.

App & License

Does the FEMS app automatically detect whether the car is being charged single-phase or three-phase?

Yes, the minimum value (single-phase 1.38 kW, three-phase 4.2 kW) and the maximum value of the charging power (single-phase 7.4 kW, three-phase 22.1 kW) change accordingly.

When phase 2 and phase 3 are switched on or off, the values above change accordingly.

For selected charging stations, the FEMS even switches between single-phase and three-phase charging by itself with automatic phase switching.

What do I need for multiple wallboxes or an entire charging park?

If you have multiple wallboxes or an entire charging park, you will need the FEMS App Multi-Charging Point Management. Since 01. April 2023, this app has been included starting with the second charging station or the second charging point. No additional app purchase is required!

Please observe the connection regulations! Commissioning may only be carried out by a qualified electrical installer with the required experience and training.

I want to replace my charging station — do I need to buy a new license key?

Provided your new charging station is supported by the FEMS, the license key you already purchased can be re-assigned to a new charging station of the respective category (AC or DC charging station).

This is done via the App Center.
