How Tridens EV Charge Is Making EV Payments Effortless

Quick Overview

CCV payment terminals read payment cards and communicate with the CCV’s back-office platform to handle card owner verification and payments. On the other hand, CCV platform also communicates with Tridens EV Charge via OCPI (Open Charge Point Interface) protocol to exchange location, charger, tariffs, and session data.

This enables the payment terminal to initiate charging sessions, keep track and eventually terminate them, using the cost for payment.

What You Need Before You Start

As a charge point operator you need:

• Active Tridens EV Charge environment with chargers onboarded. 
• Establish agreement with CCV to open a new account for card payments, merchant payment processing, acquiring, and settlement. 
• CCV device (e.g., IM30) physically installed and powered. For all the device possibilities, we advise you to check the CCV’s offer. 
• Registration token from CCV. 
• Roaming configuration for CCV, set in Roaming. 
• Pricing for sessions, set in Roaming Tariffs.

How CCV Payment Terminal Works with Tridens

CCV’s role is the payment terminal provider, abbreviated as PTP, having the back-office platform and payment terminals, which are also known as Points of Sale or POS.  

Meanwhile, operators in Tridens EV Charge platform have the role of charge point operator (CPO), controlling and monitoring charging locations and infrastructure.

Tridens EV Charge exposes your charging network via OCPI, so the CCV platform with terminals can discover chargers, control sessions, and receive cost information.  

CCV reads payment cards on-site and communicates with the CCV platform to authorize money resources based on the tariff configuration. Once authorized, the CCV requests the charging session to start on Tridens via OCPI. At session end, the final payment amount is captured from the payment card owner.

CCV Edge IM30

Serves as a contactless and card-present terminal suitable for EV charging, accepting PIN entry. Hardware wiring is included with connectivity options for mobile network, wireless internet, and cable internet. Interface graphics are adjustable to your brand.

It is possible to use this terminal on a single charger or on multiple chargers as the kiosk.

Configuring CCV with Tridens EV Charge

Let’s continue with the steps required to set up the CCV payment terminals for EV charging in Tridens EV Charge.

Step 1: Add OCPI Roaming Profile

Move to Tridens EV Charge environment, open Roaming in the left menu and create or reuse a Roaming Profile with CPO role for the OCPI protocol. Set recognizable Name and Code of your business, Role, and your three-letter Roaming ID which will represent you to the CCV. 

Find out more about Roaming Profiles.

Step 2: Add CCV Roaming Platform

Next step in Tridens EV Charge is to go inside the Roaming Profile and add the Roaming Platform of CCV.  

Populate CCV platform’s recognizable Name with Code, select PTP Type, CCV’s Roaming ID, URL and operating Country.

You can add or change Roaming Tariffs later for the cost calculations used for payments.

Step 3: Use the Registration Token

In the next step of Roaming Platform configuration, registration dialogue shows up. Insert the registration token (Token A) provided from the CCV and Submit the form. 

On the Roaming Platforms overview, select the recently created platform and hit Register Credentials action.

You can later Update credentials to renegotiate or Invalidate credentials to stop the communication.  

It is also possible to register credentials in the opposite direction, where the new token is generated by Tridens EV Charge at the platform configuration dialogue. If such principle is used, you need to pass this token from Tridens EV Charge to CCV in a secure manner, after which the CCV will do the communication handshake. Use URL that appears in the dialogue. 

Check out OCPI registration for additional explanations. 

Step 4: Expose Your Charging Infrastructure

You want to expose your charging infrastructure to the CCV payment terminal provider. To achieve this, assign a unique Roaming ID for desired Areas, Chargers and Connectors in Tridens EV Charge and enable roaming on chargers.

Connectors in payment roaming also need to have the ‘physical_reference’ custom attribute set for the CCV integration to represent a relation to its physical appearance code label.

More details about applying the roaming settings on your charging infrastructure in Tridens EV Charge is described at Areas and Roaming Profiles. 

Step 5: Assign Expense Roaming Tariffs

You need to define the expense tariffs and prices for calculating the costs of using your chargers. These costs will be used for card payments. Tariffs are schedule-based, with recurrency and one-time options. Expenses can be set for energy, charging time, parking time, and general flat fee, including VAT control and the total money reservation amount.  

Go to Roaming in the left side menu and select Tariffs, where you need to add a new Ad-hoc type tariff definition with time validity and maximum amount limit, for example 100 EUR, which is then used by CCV to authorize the money amount of the payment card customer.  

In the next step, add the Tariff Elements with cost (energy, time, flat) and recurrency time settings. 

Assign Roaming Tariffs on the charging infrastructure context (one of Site/Operator/Area/Charger/Connector) and also to the Roaming Platform of CCV.  

Step 6: Fetch Terminals from CCV

Fetch Terminals from CCV to Tridens on the Roaming Platform. Activate the CCV terminal and assign it to the desired Area and/or Connector. This way, CCV will recognize which terminal serves to which exact location, charger, and connector.

Step 7: Charger and Session Settings for Smooth Operations

As the CPO, you want to ensure that charging infrastructure events, including session events, are properly exchanged. Thus, the charger configuration in Tridens EV Charge must meet a few important considerations, so events are reported on regular intervals with sufficient data (power and energy progression) and cover border cases. This will contribute to payment terminals working properly and external users having better experience of charging.

Feel free to get through the blog How to Use Tridens EV Charge: From Onboarding to Testing the Charger. 

We advise you to follow the guidelines defined in Charging Session Integration and if facing an issue, it is likely you will find the solution for yours in the Charging Session Malfunctions page, where common cases are described with solutions and preventive measures.

Test The Full Flow

Once your CCV terminal is ready with Tridens-CCV communication established by the registration and locations with tariffs exposed, you can proceed to the test flow and try out the charging sessions initiated from the terminal.

We strongly advise you to test the following operations:

1. Approach to the CCV physical terminal, plug-in your EV and tap the screen. Find the Start button on screen. You should be able to see available locations and chargers bound to this specific terminal.   
2. Select your charger and present your payment card which will be authorized (reserved) for the max. amount configured in tariffs. 
3. If payment authorization succeeds, the charging of EV should start soon. 
4. Verify that session is charging and that you can see the progress on Tridens EV Charge portal in Sessions section. 
5. Stop the session at the terminal by presenting the payment card again.  
   1. Payment terminal shows the QR code of the receipt.  
   2. Verify that amounts are properly calculated on receipt and Tridens EV Charge portal in Sessions based on your desired Roaming Tariffs configuration. 
   3. Confirm that amount is properly captured from the payment account, meanwhile the remaining reservation amount is released. 
6. We embrace you to thoroughly test the border cases:  
   1. No charging expenses, for example if no energy is charged to EV. Expect authorized payment amount released. 
   2. Charging above the max. limit. Terminal is expected to automatically stop the session when max. amount threshold is achieved. 
   3. Invalid authorization of payment card. Charging prevented. 
   4. Request the stop of charging session from different sources: Tridens EV Charge portal, electric vehicle, terminal, charger’s emergency button. Confirm all scenarios end up in a properly completed session with payment capture. 
   5. Kiosk mode or single charger mode. Depends on your use case.
