After the introduction of the billing control unit products meeting the requirements of the national grid charging piles at the end of 2015, Mill Technology has cooperated with many charging pile manufacturers, obtained high recognition from customers in the industry, and deeply understands customer needs, and carefully analyzes the technical characteristics of the industry. The social pile (non-state network) billing control unit and charging control board have been developed successively, and based on these two types of core modules, the charging pile complete machine technical solution is provided.
Second, DC charging pile composition
From the above figure, we can see that, according to the internal component design defined by the State Grid, the charging pile can be divided into a business part and an electric part: the business part management is responsible for the charging control unit, mainly connecting the card reader, the electric energy meter, and the display. Screen and 4G network, realize interaction with operation background, man-machine display, metering and billing, charging payment, charging start and stop command delivery function; electrical part is responsible for charging device controller (charge control board), mainly connected to charging module, Insulation detection module, charging gun, etc., to achieve AC and DC conversion, vehicle BMS interaction, charging environment monitoring, electrical protection and some functions. The billing control unit and the charging control board perform real-time communication interaction through the CAN bus.
Third, Mill Technology charging pile program product features
Mill's social pile billing control unit combines the traditional serial screen solution and the national network billing unit plus the LVDS screen solution into one. It is installed in the original display position, reducing the number of components in the charging pile, enabling installation and wiring. It's even simpler. At the same time, the QT application based on the Linux operating system makes it easier to develop a friendly user interface that is close to the IOS or Android system style familiar to the end user, and supports remote upgrade applications.
The charging control board solution adopts the automotive-grade processor with high anti-interference ability. The external CAN interface, RS485 interface and DI/DO interface are isolated and protected, and conform to GB/T 18487.1-2015 and GB/T 27930-2015. The series inspection standard can successfully pass the type test of the national designated inspection and testing institution. The CAN communication protocol with the billing control unit can easily switch between the national grid charging pile and the social pile according to the requirements of the national grid charging pile, that is, with different charging control units.
Fourth, the whole process of technical servicesBased on self-developed billing control unit and charging control board, Mill Technology can provide a complete range of services from the prototype to the bulk shipment.
1. Core component selection: It can be adapted to the mainstream charging module of the industry, and provide other components according to actual needs, such as insulation detection module, card reader, electric energy meter, etc.
2. Assembly of the whole machine: Provide the whole electrical wiring diagram and bill of materials to guide the customer to install the wiring of the sample pile from scratch;
3. Debugging of the whole machine: Help the customer to complete the debugging of the charging pile and the testing of relevant testing institutions in accordance with the requirements of national standard, energy standard and enterprise standard;
4, mass production: batch supply of cost-effective billing control unit and charging control board, and provide timely and effective post-service.
V. SummaryWith the integration of embedded technology experience and charging pile technology, coupled with innovative business models, Mill Technology provides customers with charging pile machine technology solutions, which can help customers shorten product development cycle, save manpower investment, and achieve rapid product launch.
