# Schneider StarCharge Fast

> Supported devices: Schneider StarCharge Fast 60, 180 and 320 DC chargers

Source: https://voltmasters.io/en/docs/device-integrations/ev-chargers/schneider-starcharge-fast/

Our EMS supports the **Schneider StarCharge Fast** DC fast chargers over **Modbus TCP**. The station exposes a load management interface: our EMS limits its charging power and reads back what it draws, so fast charging stays within the limits of the grid connection.

### Supported devices

| Model | Current type | Connectors | Default rated power |
| --- | --- | --- | --- |
| StarCharge Fast 60 | DC | 2 | 60 kVA |
| StarCharge Fast 180 | DC | 2 | 180 kVA |
| StarCharge Fast 320 | DC | 2 | 320 kVA |

> **Note**
>
> Schneider StarCharge Fast support is available from EMS controller version **0.0.335**.

### EMS functionality

With the current integration, our EMS enables:

-   Monitoring per gun: charging state, power, vehicle state of charge, session energy and duration
-   Charging power limiting, so fast charging follows the available power at the grid connection
-   Load balancing together with the battery, the PV and the other chargers on site
-   Incidents for a station error, over-temperature, a faulted gun and a station that refuses the load management

The interface has no session start, stop or pause. Starting and stopping stays with the driver; our EMS only sets how much power the station may draw.

Additional functionality may be added over time as integration capabilities evolve.

## Setup

1. **Put the station on the network**
   
   Connect the station to the same network as the Voltmasters Controller and give it a fixed IP address.
2. **Switch Modbus to port 502**
   
   The station ships with Modbus over TLS on port `802`. Our EMS speaks plain Modbus TCP, so the station does not answer until you switch it to the non-secured port `502`. You find this setting in the web interface of the station under **Charger Configuration**, **Basic Configuration**.

   > Follow the Schneider manual for logging in to the web interface of the station.
3. **Add the station in the platform**
   
   Add a device of type **EV charger**, brand **Schneider** and model **StarCharge Fast 60**, **180** or **320**. Fill in the IP address, port `502` and the slave ID (prefilled with `1`), and check the parameters:
   
   -   **Rated power**: prefilled with the rating the model family is named after. Correct it with the rating on the nameplate: a Fast 180 is also sold as a 150 kW unit, and the station itself reports the family rating, not its own.
   -   **Fallback setpoint**: the power in kW the controller leaves the station at when it stops. Left empty, 60 kW is used. Choose a multiple of 30 kW, the block size in which the station allocates power.
   -   **Load balancing mode**: leave it on **Charger only**. The other modes are offered, but the tested firmware does not accept per-gun control and the station then raises a load management incident.
4. **Verify**
   
   Start a charging session and check on the device page that the charging state and the power come in, and that the station follows a lowered power limit.

> **Warning**
>
> **No fallback on the station**
> 
> The station has no working protection against a lost connection: its own offline fallback is cleared by the very disconnect it is meant to cover. That is why the controller writes the **Fallback setpoint** to the station when it stops. Set it to a value the grid connection can carry without the EMS.

> **Note**
>
> **Load management refused**
> 
> When the station keeps reporting a different limit or control mode than the one written to it, our EMS raises an incident and no longer allocates power to it, so a station that ignores its limit does not go unnoticed.
