Pico Configuration

On this page you will find the most important configurations related to the Pico hardware.The configuration of the Pico charging station is always done via the smart-me platform in the first step. Subsequently, the authentication method can be enabled via a backend system (eCarUp).

Authentication (private, semi-public, public)

The Pico charging station can be used with or without the authentication method.

None: No authentication required for charging. (Charges as soon as plugged in)

Configuration with backend / authentication:

To operate a Pico publicly, semi-publicly, or to use any kind of unlocking functions, the station must be operated in backend mode using eCarUp.

Unlocking functions:

  • RFID

  • manual On / Off via App

  • QR codes

  • CarID (requires activation in the advanced settings in the smart-me portal)

As soon as "Backend" is selected, the station is automatically added to the eCarUp account of the same name. (same username and password as for smart-me). Details on the configuration of eCarUp and public charging stations can be found in our eCarUp Wiki: https://ecarupwiki.smart-me.com

Pico setting in the smart-me portal:

eCarUp Portal:

Configuration for private use with RFID authentication


  1. Navigate to Stations → Administration in the eCarUp Portal

  2. Edit --> Edit connection


prices = 0 CHF, Zugriff: Privat

Configuration for limited use with RFID authentication (tenants with special rates)

  1. Navigate to Stations → Administration in the eCarUp Portal

  2. Edit --> Edit connection

3. choose prices

4. define special users and their prices

The drivers create their own account at eCarUp and communicate the account name to the station owner for registration in the station.

Personalising the Pico display

The name of the station can be freely chosen and the display can be personalised if not used. In addition to the designs already available, you can also upload your own GIFs or images.

  • Supported formats: JPG, PNG, GIF

  • Resolution: 32x32 pixels

  • Size: max. 200 kB

  • Background should be completely black (#000000)

  • Animations (GIF) have 10 frames/s (100ms per frame)

Note: You will get the best image result if you make sure that the image is uploaded 32x32 pixels in GIF format during creation and editing.

Load management and current limitation

Limit station power

The Pico charging station can be limited by default when installed.

This setting is taken into account by the automatic load management and is never overwritten.

With the maximum charging current setting, the maximum power of the station can be fixed. The limit can be set in 1 ampere steps.

32A = 22kW maximum power

16A = 11kW maximum power

The minimum current setting can be used to prevent charging or to set suitable minimum currents to start charging a car.

Note: There are vehicles that cannot start charging with a starting current of 6A, this is due to the technology installed in the vehicle. If this is the case, the minimum current can be set higher.

Static load management (ward group)

Static load management regulates stations within the same load management group. The function prevents the maximum current on the supply line, e.g. ribbon cable, from being exceeded and regulates the distribution of the available current to the stations. The charging group size is technologically unlimited.

Function in detail:
The charging stations regulate themselves on the basis of the defined maximum available current. The 3-phase charging power is distributed to all charging stations until the minimum charging power of 3-phase 6A can no longer be made available to all charging cars. After that, charging is switched to 1-phase. All cars continue to charge 1-phase with the maximum possible current per phase (phase switching). Further charging only becomes impossible when all cars already charging have reached the minimum of 1-phase 6A. As soon as one of the charged vehicles leaves the charging station, the reserved charge is released for another one.

Configuration:

  1. Create load management group (New group)

  2. Define the maximum current of the supply line

  3. Add stations to the corresponding load management group (Edit)

Dynamic load management (station groups with reference measurement)

Dynamic load management enables the consideration of a reference point and the control of the maximum currents at this reference point.In e-mobility, either the house connection point or the distribution point is selected for this purpose.

Planning load management

The following products are suitable as hardware for reference measurement:

Telstar 80A

Telstar CT

The configuration of the dynamic load management is done via the if/then actions.

Details and examples you can find here: if/then actions.

Accordingly, you can have a flowing influence on the station groups maximum currents, taking into account the current at this reference point.

Load shedding

Hardware load shedding (external Pico inputs)

Pico Lastabwurf

Load shedding can also be realised using only one available signal. For the configuration from no charge to maximum charge power, the signal is wired to IN1 and IN2 as well as COM. For the configuration from 6A minimum power to maximum charging power, the signal must only be wired to IN2 as well as COM.

Attention:
The load shedding can either be wired to all Picos or minimally to one from each static load group.
T
his function is also functional if there is no internet connection but Wifi.

Cloud based load shedding

The load shedding can also be realized with the IF/THEN actions. THe advantage is that no signal has to be connected to the Pico hardware, instead a signal on any other hardware (counter) can be applied and be used as a trigger.

The disadvantage though is that the function can not be executed if there is no internet connection.

More details on setup: If / Then Action

Commands

Here you can unlock the cable, restart the station or show the counter reading on the display for verification.

Advanced settings

  • Auto Car Detection: For CarID authentication to work, you must enable the station's communication to the vehicle.

  • Modbus TCP: Enable Pico's Modbus TCP interface.

  • Delete station: Deletes the station and all data on the cloud.
