AI Technical Summary

Technical Problem

In large charging stations, the excessive demand for electric vehicle charging leads to insufficient power grid, causing charging piles to suddenly shut down and affecting their lifespan. Existing power supply methods are limited and cannot meet user needs.

Method used

By acquiring the load current of the target phase, the target regulating current is determined based on the charging mode, load current, desired current, and battery current of the charging equipment. The charging current of each charging equipment is then adjusted, including current regulation strategies in energy-saving mode and fast charging mode. Priority is given to utilizing new energy power supply, grid current is rationally allocated, and frequent start-stop operations are avoided.

Benefits of technology

It improved the user experience of charging equipment, enriched load constraint control strategies, extended the service life of charging piles, and optimized the utilization of power grid.
