1. Understanding Pay per Charge

Monetize Your Wallbox Chargers with Pay per Charge

You can easily earn money from your Wallbox chargers by using the Pay per Charge billing solution. With this method, you can charge users each time they use your charger to power up their electric vehicles (EVs). Managing payments is simple, thanks to the user-friendly interface of the Wallbox portal.

Prefer Monthly Subscriptions? No Problem!
If you have a regular user base, like your company’s employees, and prefer offering them a monthly subscription plan, you can opt for the Pay Per Month method. Find out more about it here.

2. Before Starting

2.1. Setting up your Wallbox Account

To begin using Pay per Charge, you need to:

1. Create a Wallbox account.
2. Add your charger(s) to your account.
3. Connect your Stripe account to your Wallbox account in the Portal.

Once your account is set up, ensure that the Technical Requirements below are met:

2.2. Technical Requirements

For Pay per Charge to work smoothly, ensure:

1. Internet Connection: Both the user’s Wallbox app and your charger must be connected to the Internet.
2. MID Metering: Your chargers must be equipped with a MID meter to sell energy in specific countries.

3. Creating a Pay per Charge Billing Rate for Your Charger(s)

A rate is a fee you define in the Wallbox portal and will be billed when someone charges their EVs with your charger. They are highly customizable and can be changed at any time.

3.1. Available Rate Options

The Pay per Charge feature, just like the monthly billing solution (Pay per Month), lets you choose between three charging methods:

1. Time Reservation Fee (charged in Price — EUR* / Hour)
2. Consumed Energy Fee (charged in Price — EUR* / kWh) – your charger must be equipped with a MID meter to use this charging method.
3. Charging Time Fee (charged in Price — EUR* / Hour)

On top of the abovementioned fees, you can add a fixed service fee that will apply to all your users’ charging sessions. It can be likened to a charger unlocking fee.

You can also assign a rate to a specific schedule.

*The currency depends on the configuration of your Organization.

3.2. Creating and assigning a Pay per Charge rate

To monetise your charger(s), you must create billing rates and assign them to your charger. Follow the steps below to create and assign a rate to a charger:

1. Log in to the Wallbox portal.
2. Go to Chargers.
3. Select the charger you want to monetize.
4. In the Connectivity section, click Payments and then Pay per Charge.
5. Enable the Pay per Charge option.
6. Select or create a rate.
7. Add the rate to a schedule.
8. Name and configure your rate.
9. Save.

Your rate is now assigned to your charger!

3.3. Modifying your rates

You can modify and fully manage all your rates at any time following this path: Payments (in the left menu) > Rates.

From there, you can view all your rates and their properties (variable fee type, price, schedule …) and check if they are assigned at a glance. You can also create new rates, delete them or modify them directly from this area.

4. Making your charger accessible to users

Your charger is now set up correctly. The last steps you must go through to ensure your users can access your charging points are the following:
