Technical analysis of EV charger‘s POS payment system

The POS payment system of EV chargers is a complex system involving technology, hardware, and protocol docking. Now let’s learn this together:

1. Two types of EV charger systems:

In the field of EV chargers, there are two main management systems, namely the system based on the OCPP protocol and the intelligent credit payment system.

OCPP protocol management system: This system supports multiple payment methods, including APP payment and RFID card payment,

and can remotely manage EV chargers through the OCPP server. EV chargers become more flexible and controllable, providing convenience for operators.

Smart credit payment system: POS hardware plays a key role. This system works in conjunction with POS hardware to provide users with more intelligent and diverse payment methods.

These two types of EV charger management systems enable users to choose the payment method that suits them according to their personal needs, increasing the flexibility of the system.

2. Payment methods supported by POS hardware:

In the EV charger POS system, POS hardware is the core component to realize the payment function. Among them, a contactless POS machine is a common hardware device that supports multiple payment methods,

including Apple mobile phone NFC payment, iWatch payment, credit card payment, and Google payment.


3. State-supported POS machines and docking process:

Globally, countries have different levels of support for POS machines. For EV charger operators, if they want to introduce a POS payment system, they need to understand the target country’s support for EV charger POS.
A: Operators first need to consult the EV charger manufacturer to confirm whether its POS is available in the target country. If the manufacturer already has a case in the destination country, it will save effort for the operator. If the authenticity is confirmed, subsequent details can be communicated with the manufacturer.
B: If the manufacturer’s reply is still under development, don’t worry, because the docking process is not difficult and can be completed in one or two months.
C: But if the manufacturer replies that the target country does not currently support POS, the operator needs to proactively find local POS equipment and provide samples and protocols to the manufacturer. Operators can ask the manufacturer for pictures of product cases and agreement documents they have received for reference. After the manufacturer receives the required information, it will connect the POS with the EV charger in terms of software and hardware. The connection fee is only a few hundred dollars and takes one or two months, which is very fast. This process requires detailed communication and cooperation to ensure that the EV charger POS system can be successfully promoted and applied in different countries.

4. Specific steps for manufacturers to connect with EV chargers:

The docking process between manufacturers and EV chargers involves the collaborative work of software and hardware,

in which the design and implementation of protocol commands is a crucial step.

During the docking process, manufacturers need to carefully analyze the protocol commands, determine the key commands,

and design and implement them accordingly. For example, you can consider commands for EV charger start, stop, charging status, etc.

This process requires a high degree of technical expertise to ensure smooth connection between EV chargers and POS systems.

Operators should find EV charger manufacturers that produce their hardware and software,

which means that their R&D capabilities and professionalism are reliable. There is no problem with EV chargers equipped with POS payment systems,

and secondly, after-sales service is also worry-free because each manufacturing process is completed in one’s own hands,

it is very convenient to improve any problem, upgrade the process, and innovate the program.

5. The relationship and registration process between EV charger operators, gateway companies, and acquirers:

The relationship between EV charger operators, gateway companies, and acquirers is an important link in building an EV charger POS payment system.

The process of registering as a merchant involves multiple steps to ensure the proper functioning of the system.

First, operators need to submit the necessary information to the acquirer and undergo a KYC review. After passing the review,

the merchant will obtain a unique merchant ID number, which will be bound to the SN number of the POS machine for activation.

This process is completed through the gateway company’s network, ensuring the legality and security of the EV charger POS system. After the binding is activated, the operator can collect payments.

Payment transaction process

6. Prerequisites for using the user’s credit card:

The use of the user’s credit card in the charging station POS system needs to be completed through operations and documentation pures between the user, the card issuer, and the card organization.
Users need to establish a trust relationship with the card issuing bank, and the card organization needs to provide corresponding network support. Under this premise, the user’s credit card can successfully pay in the EV charger POS system. This process involves the collaboration and cooperation of multiple parties to ensure the security and reliability of user payments.

7. POS payment transaction process of EV charger:

The POS payment transaction process of EV chargers is a multi-link system operation to ensure that users can successfully pay through POS machines.
The user pays the merchant by swiping the POS machine, and the transaction is sent to the acquirer through the gateway company’s network. The acquirer sends the transaction request to the card issuer through the card organization’s network, and the card issuer authorizes the transaction and returns the transaction end, indicating that the transaction is successful. The entire process is implemented through an efficient network system, ensuring the smooth progress of payment transactions.
