With the rapid popularization of new energy electric vehicles, the construction of charging pile infrastructure is accelerating, and the grid pressure and peak-valley power imbalance problems brought by centralized charging have become increasingly prominent. Charging pile supporting energy storage batteries are professional energy storage and peak-shaving equipment matched with charging pile systems, which can effectively solve the problems of grid overload, charging power shortage and high peak electricity cost in the process of electric vehicle charging, and build a more efficient and economical new energy charging system.

The core working mode of supporting energy storage batteries for charging piles is peak shaving and valley filling. It automatically stores electric energy during the low electricity price period and low grid load at night, and releases power to supply charging piles during the peak electricity consumption period in the daytime. This mode not only avoids the impact of large-scale centralized charging on the stable operation of the power grid, but also greatly reduces the electricity cost of charging stations. For community charging stations, highway service area charging piles and commercial centralized charging stations, this energy storage matching mode can effectively alleviate the problem of insufficient grid capacity and avoid the need for expensive grid transformation.

In addition to economic and grid stabilization benefits, charging pile supporting energy storage batteries also improve the reliability and flexibility of charging services. In case of temporary grid power failure or voltage instability, the energy storage battery can be used as an emergency power supply to ensure the normal operation of charging piles and avoid interrupting vehicle charging. At the same time, the intelligent energy storage management system can dynamically adjust the discharge power according to the number of online charging vehicles and charging demand, realize balanced power distribution, improve the charging efficiency of the equipment, and extend the service life of charging piles and grid equipment.

Moreover, this supporting energy storage equipment is compatible with various types of DC and AC charging piles, with strong scalability. It can be flexibly configured according to the scale of the charging station, and can also be combined with distributed photovoltaic power generation systems to form a photovoltaic-storage-charging integrated system, realize self-generation and self-use of clean energy, further reduce carbon emissions, and conform to the development trend of new energy and green low-carbon transportation.
