MID Compliant Features

To enable MID compliant features, ensure that it is selected during commissioning of the charger.

Billing Process and Procedure with Public Key

At the end of each charging session, the Wall Connector will export the digitally signed billing record for processing and payment. The signed billing record is provided to the end customer alongside the invoice for independent verification of the meter’s readings during the session.

For every charge session billed, both files are made available in the charge history in the user’s Tesla account, accessible from the Tesla mobile application:

The customer can verify the authenticity of the record by uploading it to Tesla’s transparency software: https://www.tesla.com/charging/verify

Navigating to the transparency software you will be greeted by the page shown in figure below where you will input the “Charge Session Data” file downloaded from the mobile app. The file comes with the public key pre-filled, so once the file is uploaded, select ‘Validate’ to verify the authenticity of the data and view the content.

Optionally, the charger's public key can entered manually be tapping the field and entering the values, or scanning the QR code located on the charger, as shown in the figure below:

Errors and Failed Validation:

During operation several errors or faults can occur that would lead the meter to mark the present or any upcoming session as invalid. A charging session occurring under any of the following failure types will be marked as invalid. The live display will inform the customer of an error having occurred during the session, and the backend is expected to not bill the customer for the session.


Error Type	Error Displayed
Meter’s system time is unsynchronized	Time Error
Meter’s configuration is not locked	Session Error
Meter is not commissioned
Meter’s logbook is full
Corruption detected in the meter’s memory
Rationality check failed

In the event of the billing record failing the authenticity check, the Transparency Software informs the user with the following warning:

Home Charging Reimbursement Setup

The Home Charging Reimbursement program allows you to reimburse the home charging costs of your company electric vehicle through Tesla partner apps.

A list of currently supported partner organizations can be found here: https://www.tesla.com/en_gb/support/charging/wall-connector/charging-reimbursements

To register your Wall Connector,

Visit the program website and follow their signup instructions. You will be linked to your Tesla Mobile App to complete the setup.
Select if you wish to consent to data sharing with the partner app.
Select the Wall Connector you wish to register.
You will see when the Wall Connector is successfully enrolled. This may take a few minutes.

Display Screen

Wall Connector comes with an integrated character LCD screen on the side for displaying metering data. The following data is shown on the live display (values are for reference only):

Table 1. Fields displayed in idle state and during an active session
Field	Description	Display (Example)
Lifetime Energy (Totalizer)	Energy measured since manufacturing of the meter.
Meter Firmware (Version)	Meter’s firmware version.
Serial Number (Unique Identifier)	Serial number of the meter.
Warnings, errors, faults	Field used to show warnings, errors or faults.

Table 2. Fields displayed during an active session
Field	Description	Display (Example)
Session Energy	Energy delivered during the charge session.
Start Date	Start date of the session (in local time).
Start Time	Start time of the session (in local time).
Session Length	Duration of the charge session.
Session ID	Monotonic counter uniquely assigned to every charge session.

The display continuously cycles through the screens above from the moment the Wall Connector is powered on and the MID compliant features are enabled. The cycle period is 5 seconds. Session-related data is retained for 5 minutes after the session ends (i.e., when the handle is unplugged).
