Intro
Authorization is needed to restrict access to EV charging infrastructure to a select group of EV owners. Read on to find out how to create and maintain whitelists.
Free charging
Free charging allows anyone to charge their EV vehicle at any time and at no cost.

Free charging mode flowchart
Use the following chart to help choose the Free Charging Mode that makes most sense for your situation.
Free charging modes overview
| Free charging mode | OCPP backend communication | RFID authorization | Info |
|---|---|---|---|
No OCPP | |||
With OCPP status notif without auth | Limited OCPP communication (status only) | ||
With OCPP status notif with auth | |||
With OCPP Full fixed RFID with auth | Complete OCPP communication | ||
With OCPP Full fixed RFID without auth | Complete OCPP communication | ||
With OCPP Full any RFID | Complete OCPP communication |
Free charging in combination with a backend connection allows Operators to show if a Charging Station is occupied.
Without a backend connection
Apply the following configuration:
| Location in Dashboard | Parameter | Value |
|---|---|---|
| AUTHORIZATION > Free Charging | Free Charging | On |
| AUTHORIZATION > Free Charging | Free Charging Mode | No OCPP |
- At the bottom of the window, click , then click to apply the changes
After the restart, charging is unrestricted.
Charging starts immediately after a connection to the car is established.
Potential users can't see whether the Charging Station is free or occupied.
Charging session protocols are only provided through log files.

UID letter case
Take the display format into account when reading the UID. For our controller, the hexadecimal code must always be used. When entering the UIDs, the representation form must match the selection in the RFID Tag letter case field.
UID format examples
| format | Example UID |
|---|---|
| Lower case | 0a0e9b83 |
| Upper case | 0A0E9B83 |
| Lower case reversed byte order | 839b0e0a |
| Upper case reversed byte order | 839B0E0A |
It is not always obvious in which byte order the UIDs are specified. If in doubt, try both variants.
Relevant parameters reference
Here is an overview on the general settings that affect how authorization is handled:
| Scope | Location in Dashboard | Parameter | Value | Info |
|---|---|---|---|---|
| Operator | AUTHORIZATION > Free Charging | Free Charging | ||
| Operator | AUTHORIZATION > Free Charging | Free Charging Mode | ||
| Operator | AUTHORIZATION > Free Charging | RFID Tag for Free Charging with OCPP Full, fixed rfid modes | ||
| Operator | AUTHORIZATION > Free Charging | RFID Tag for Free Charging with OCPP Full, fixed rfid modes (Connector 2) | ||
| Operator | AUTHORIZATION > Free Charging | If in doubt allow charging | Off | The charging process is not started until the Charging Station receives a response from the backend and the user has been authorized. In extreme cases, this will result in the user not being able to charge. |
On | In this case, the charging process is authorized even if there is no feedback from the back end. However, as soon as this occurs, the loading process is subsequently canceled if necessary. | |||
ImmediatelyWhenPlugged | Here, the charging process starts immediately after the charging cable is plugged in. The user's RFID is not checked until the charging station has reconnected to the back end. If necessary, the charging process is then aborted. The difference to "On" is that here no RFID has to be presented at all to start the charging process. | |||
| Operator | AUTHORIZATION > General | Vehicle connection timeout | ||
| Operator | AUTHORIZATION > General | Send Authorize for RemoteStart | ||
| Operator | AUTHORIZATION > General | Stop Transaction Mode | Normal | The cable is released and the transaction stopped when the cable is removed from the car or the RFID used to authorize the charging process is presented again. |
| Operator | AUTHORIZATION > General | Stop Transaction Mode | Stop only by unplugging | The transaction will not stop completely until the cable is removed from the Charging Station. |
| Operator | AUTHORIZATION > General | Stop Transaction Mode | Unlock only by RFID/RemoteStop | The charging transaction will not stop until the authorized RFID is presented again or an appropriate (remote stop) message is transmitted from the backend. **Caution: removing the cable from the Charging Station does not terminate the transaction. |
| Operator | AUTHORIZATION > General | Stop Transaction Mode | Normal + Mode D | Same as Normal, wowever, it is supplemented by two cases in which the transaction is also terminated. One is when the vehicle switches to the so-called charging mode D (see EN 62196 Type 2). This signals the vehicle that the battery is "outgassing". However, the problem of outgassing does not occur with lithium-ion batteries, which is why charging mode D never occurs in practice. Second, when a fault current is detected and the residual current device (RCD) trips. This immediately interrupts the power supply. However, using this option requires the RCD to communicate with the controller and signal when it has tripped. However, this is not the case with the Berlin Charging Station, for example. |
