Process overview

What are the next steps?

1. Invitation to the service

You will be invited to the Charge Repay Service by your fleet manager by e-mail. The prerequisite is (currently) an already installed wallbox. You can use the invitation to create an account with our service.

2. Hardware order

After registering, you can select your installed wallbox model and provide information about your installation. Finally, you can order the hardware required to connect your wallbox and receive an order confirmation.

3. Hardware installation

The hardware will be delivered to the address you specified. At the same time, our service technicians will contact you to arrange an appointment to install the hardware. The service is active after installation.

4. Ongoing operation

In the service you can view your charging processes and the expected reimbursement. You can differentiate between private and company cars and make changes to the electricity and mileage data.


Frequently asked questions

Thanks to our three different connection variants, all common home wallboxes can be connected to the Charge Repay Service.
The Charge Repay Service is a complete solution for the billing of home charging processes for company car drivers. The special feature of the service is that any wallbox model can be used for billing, regardless of manufacturer and protocol.
The Charge Repay Service is a combination of software and hardware. The hardware is required to make the wallbox billable. Newer (calibration law-compliant) wallbox models can also be billed without additional hardware. Drivers can use the web app to enter their electricity price, view the charging processes and assign them as business or private.
For company car drivers, the main advantage of the service is that they can use their existing wallbox for charging and do not have to replace it. This saves costs and protects the environment. In addition, the driver can distinguish between private and business charging and does not have to buy an expensive wallbox that complies with calibration law.
Thanks to the additionally installed hardware, any wallbox model with a charging point can be used for billing via the Charge Repay Service, regardless of manufacturer and transmission protocol. The charging processes are recorded by the built-in meter and are therefore also independent of firmware versions and model series.
If your company requires calibration-compliant billing, there are two different ways to connect the wallbox. A wallbox that complies with calibration law can be connected directly. This means that you have to make certain settings in the web interface of your wallbox so that the billing data can be transferred to our service. You will receive all further information during the onboarding process.
If you have installed a wallbox that does not comply with the calibration law, our installation service provider will install additional hardware that allows you to distinguish between business and private charging. You will receive all further information during the onboarding process.
With the Charge Repay Service, it is generally possible to differentiate between business and private charging transactions. The allocation and authentication of billing transactions is carried out via the web app provided. Legislation stipulates that an overall system that complies with calibration law must be used in the home sector. A MID-compliant meter in front of or in the wallbox is sufficient as long as only the company car is being charged. In the likely event that another vehicle is also charged at the wallbox (albeit irregularly), we have developed a patented procedure for differentiating between vehicles. However, this requires a hardware retrofit if no so-called calibratable wallbox is available. With the help of the built-in MID meter, older and previously non-verifiable wallbox models can also be used for verifiable billing.
You can access the service at any time at . Your current status of the onboarding process will be saved. We recommend that you save the website as a tab on the home screen of your cell phone so that you can access the service quickly at any time.
No, only the business charging processes are forwarded to the company for invoicing.
If you have technical questions or questions about the connection and the process, please contact .
You can enter a new electricity price, including a new contract, in the service via Settings.
Use the ENTER and UP buttons to navigate to the correct page.
ENTER: Scroll through display pages
UP: Scroll through display subpages

Use the ENTER button until you see “kWh” and no longer “T1” or “T2” on the display. Then press the UP button until you see “→” and “∑”. The displayed value corresponds to the total meter reading in kWh (not resettable).

CRG 0002 WIFI, LTE - Gateway
10002, 10003

The Charge Repay Gateway records charging data via local interfaces of the wallbox or an energy meter and forwards this encrypted WiFi/LAN to the Charge Repay Service.
With automated onboarding, it is easy to put into operation and, in combination with a corresponding energy meter, enables billing of charging processes in the home in compliance with calibration law.
