Support remote monitoring, fault alarm, remote upgrade (FOTA) and other functions to facilitate management and maintenance by operators and enhance user experience.

• Rich functional integration and scalability: In addition to basic charging control functions, it also integrates various functions such as voice broadcasting, emergency stop detection, adhesion detection, etc. At the same time, it has rich peripheral expansion interfaces and can achieve different product positioning and application coverage for customers by selecting industrial grade display screens, indicator light boards, card readers, 4G/wired network communication modules and other accessories.

Safety and reliability advantages:

• Multiple safety protection mechanisms: equipped with multiple safety protection measures such as over temperature protection, short circuit protection, overload protection, leakage protection, overcurrent protection, lightning protection, relay adhesion detection protection, etc., it can automatically cut off power in abnormal situations to ensure the safety of the charging process. The input and output have dual safety protection measures, and the connection status of the charging cable can be monitored in real time during charging. If the connection is abnormal, the charging will be terminated immediately.

• High protection level and wide temperature range operation: It has a high protection level, such as IP54 or IP65, and can adapt to different environmental conditions. It can be installed indoors or in sheltered outdoor environments to resist the invasion of environmental factors such as dust and rain. At the same time, it has the ability to operate in a wide temperature range and can work normally within a wide temperature range, adapting to various climatic conditions.

• Industrial grade circuit board design and stability: Adopting industrial grade circuit board design, easy installation, effectively reducing the production cost of charging pile manufacturers. Has good anti-interference ability and stability, and can operate stably for a long time under different environmental conditions.

Cost and market advantages:

• High cost-effectiveness: Compared with fast charging devices, the hardware and installation costs of the 7KW AC charging station motherboard are lower. Its structure is relatively simple, and the internal components are easy to inspect and maintain, reducing maintenance costs and time, which can save users long-term operating costs.

• Large market demand: 7KW AC charging piles play an important role in the charging infrastructure of new energy vehicles due to their moderate power and wide applicability. With the rapid growth of new energy vehicles worldwide, the demand for charging infrastructure, especially AC charging stations, is increasing, and the market prospects are broad.

• Strong compatibility: Supports communication with the battery management system of electric vehicles, compatible with charging communication protocols of different brands of electric vehicles, achieving wide compatibility, and ensuring that the charging station can be compatible with multiple models of electric vehicles.

Advantages of Intelligence and User Experience:

• Dynamic adjustment and monitoring: During the charging process, the control board continuously monitors the charging status, including current, voltage, temperature, etc., and dynamically adjusts the charging parameters as needed to ensure safety and efficiency.

• End charging management: When the battery approaches full charge or the user stops charging, the control board will safely disconnect the charging process according to the prescribed procedures to complete the charging process.

• Intelligent payment and human-computer interaction: Built in intelligent payment system, supporting external 4.3-inch or 7-inch industrial control display screen, visual management of operation status, and some also have QR code mobile scanning payment function, simple and easy to operate, convenient for users to charge and pay.

Advantages of R&D and Industry Promotion:

• Functional integrity and technological maturity: usually have relatively complete functions such as charging control, security protection, communication management, billing and metering, status monitoring, and protocol compatibility. These functions are the core functions of the charging pile motherboard. When developing charging pile motherboards for other powers, these basic functional modules are also required, but specific parameters and performance may be adjusted. The 7KW AC charging station technology is relatively mature, and after long-term market testing and continuous optimization, it has accumulated rich experience in circuit design, control algorithms, communication protocol processing, and other aspects of its motherboard. R&D personnel can easily expand and improve based on these mature technical solutions to meet the needs of other power sources.

• The principle of power regulation is similar and scalable: the control of power by the charging pile motherboard is mainly achieved by adjusting parameters such as current and voltage. The 7KW AC charging station motherboard already has mature control strategies and circuit designs in power regulation. Other power charging station motherboards can learn from its principles in research and development, and make corresponding adjustments and optimizations according to different power requirements. The 7KW AC charging station motherboard usually has a certain degree of scalability in hardware design, such as increasing power modules and optimizing heat dissipation design to improve power. This scalability provides a foundation for the development of higher power charging pile motherboards, and researchers can improve and innovate on the 7KW motherboard, reducing the difficulty and cost of research and development.

• The mainstream of household charging piles is compatible with multiple vehicle models: In the home charging scenario, 7KW AC charging piles are currently one of the most widely used types, with power that can meet the daily charging needs of most household users. Developing other power motherboards with good compatibility with 7KW AC charging station motherboards can better meet market demand, facilitate users to choose and switch between different power requirements, and improve the universality and compatibility of charging stations. The 7KW AC charging station motherboard is usually compatible with most new energy vehicle models on the market. When developing other power charging station motherboards, maintaining compatibility and communication protocol consistency with the 7KW motherboard can ensure that the newly developed motherboard can also adapt to multiple vehicle models, reducing promotion and usage barriers caused by incompatible vehicle models.

• Scale effect reduces costs and improves research and development efficiency: Due to the high market demand for 7KW AC charging piles, the production of their motherboards has formed a certain scale effect, resulting in relatively low costs. When developing other power charging pile motherboards, utilizing the existing supply chain and production process of 7KW motherboards can reduce research and development and production costs to a certain extent, and improve the market competitiveness of the product. Based on the 7KW AC charging pile motherboard, the research and development of other power motherboards can reduce repetitive work in the research and development process, shorten the research and development cycle, launch new products faster, meet market demand, and thus improve the economic efficiency of enterprises.
