As global energy and environmental challenges continue to intensify, governments and automakers worldwide have come to recognize that green, environmentally friendly electric vehicles represent the future direction of automotive technology and industry development. The Chinese government has placed great emphasis on the development of electric vehicles; to facilitate the transformation and upgrading of the automotive industry, the General Office of the State Council approved and issued the “Guiding Opinions on Accelerating the Promotion and Application of New Energy Vehicles” in July 2014, followed by a series of policies aimed at supporting and fostering the growth of the electric vehicle sector. The widespread adoption of electric vehicles is inseparable from the construction and improvement of supporting infrastructure, with charging stations serving as a key component of this infrastructure.

Electric vehicle charging stations can be categorized into DC chargers and AC chargers. DC chargers offer high charging capacity and short charging times, but require substantial capital investment and occupy a large footprint, making them suitable for large electric vehicles and centralized charging at major charging stations. In contrast, AC chargers have lower charging capacity and longer charging times, yet they involve lower capital costs, smaller footprints, and easier installation, making them ideal for residential communities, public parking lots, office buildings, Party and government institutions, and enterprises and public institutions. In line with national policy guidance and market demand, our company has developed EV charging stations that feature a variety of intelligent charging modes, including timed charging, quantity-based charging, fixed-amount charging, and automated charging. The products adopt a modular design, comprising a master control module, an electrical circuit module, a communication module, an energy metering module, and a security module. They support multiple communication protocols, such as Ethernet, GPRS, RS-232, and RS-485, enabling real-time data exchange with power monitoring back-end systems and billing systems; moreover, payment via QR code scanning can be used to settle electricity charges, thereby ensuring the accuracy and reliability of metering and billing data.
