The charging pile energy storage and supplement power unit is an efficient and intelligent energy storage charging device tailored for new energy vehicle charging scenarios, urban public charging stations, community charging supporting facilities and highway service area charging systems. It effectively makes up for the shortcomings of traditional fixed charging piles, such as fixed installation positions, limited power capacity and easy overload operation during peak power consumption. This equipment integrates energy storage, power buffering and emergency supplementary power functions, adopting advanced battery energy storage technology and intelligent power distribution control system, which can store electric energy during low power consumption periods and valley electricity price periods, and release electric energy to supplement power for charging piles during peak power consumption periods, realizing peak shaving and valley filling of charging power.

In terms of operational performance, the charging pile energy storage supplement power unit has strong power compatibility and expansion capability. It can be seamlessly matched with various types of DC and AC charging piles on the market, and support simultaneous charging of multiple new energy vehicles without voltage drop and power attenuation. The built-in intelligent frequency conversion and voltage stabilization module can effectively resist grid voltage fluctuation and current impact, stabilize the output power of charging piles, and avoid charging failure or equipment damage caused by grid instability. In addition, the equipment is equipped with perfect safety protection mechanisms, including overvoltage, undervoltage, overcurrent, short circuit, overheating and lightning protection functions, which can automatically cut off the power supply in case of abnormal conditions to ensure the safety of charging equipment and vehicles.

This power unit also has outstanding energy-saving and economic benefits. By utilizing valley electricity for energy storage and peak electricity for supplementary power, it greatly reduces the operating electricity cost of charging stations and solves the problem of grid overload and power supply shortage during peak charging hours. At the same time, it can be used as an emergency backup power supply. When the municipal grid is powered off or fails, it can continue to provide charging services for new energy vehicles, improving the service continuity and reliability of charging stations. Its compact and standardized cabinet design is convenient for outdoor installation and centralized management, and it can be widely promoted and applied in urban public charging infrastructure construction, providing strong technical support for the popularization and development of new energy vehicle charging systems.
