With the promotion of national policies and the popularization of green travel awareness, the number of car owners choosing to buy new energy vehicles has increased year by year. The continuous increase in the number of new energy vehicles has directly promoted the growth of the demand for charging piles and promoted the development of the charging pile industry.

With the accelerated deployment of charging piles, the further improvement of high-power charging demonstration and verification technology for charging technology, and the accelerated promotion and application of power exchange facilities, diversified scenarios for charging methods for new energy vehicles have emerged.

According to the operating mode, there are currently the following types of charging piles:

1. Public stakes and shared private stakes

The main user groups of public charging piles are online car-hailing, buses, and logistics vehicles; shared private piles are charging piles that are built by new energy vehicle owners to meet the charging of private vehicles and can provide charging services to other vehicles.

2. Build a charging pile with the car

Refers to the charging piles installed in a new energy vehicle or the piles used in the charging station provided by the car factory.

3. Charging and Swap Station

The charging station is an energy station that provides charging and quick replacement of the power battery for the power battery of the new energy vehicle

Although the operation modes of the above charging piles (stations) are different, and the charging business process is also different, one thing is the same is that the core control system of the pile body generally adopts the main control board of the embedded ARM architecture (charging pile billing control Unit and charging pile centralized control unit).

Forlinx Embedded is one of the earliest companies in China to develop and produce charging pile charging control units. Since 2015, it has developed the charging pile industry market and has successively developed State Grid charging pile charging control units and non-State Grid charging pile charging control units. Units, charging station centralized control units and other products have accumulated rich experience in product implementation in the process. This article will introduce the FCU2401 billing control unit, FCU1103 billing control unit, and FCU1302 billing control unit to help users make choices based on the application requirements of different scenarios.

Forlinx’s billing control unit has the following features:

• ● Stable quality, all components of the core module reach industrial grade -40℃~85℃
• ● With friendly human-computer interaction interface, Linux+QT interface display is easy to operate;
• ● Support RS485 interface and electric energy metering device communication;
• ● Support CAN bus and BMS communication of electric vehicles to realize the electric quantity measurement and charging control of electric vehicle batteries; support CAN bus to communicate with the charging controller to realize the centralized control part of the charging pile;
• ● It can realize the voice system prompt, which is more humane;
• ● Local SD/MMC memory card, which can realize local large-capacity data storage;
• ● Support Ethernet interface, 4G module, to meet network transmission requirements in different environments;

The specific functional parameters of the three charging control units are as follows:
