AI Technical Summary

Technical Problem

There is a need to balance the vehicle functions of electric vehicles, which enable V2X capabilities, with their functions as large-capacity storage batteries, particularly in scenarios where rapid charging may exceed the power capacity limits of the facility's power source.

Method used

A charging/discharging system and control method that manages the charging and discharging of multiple electric vehicles within a facility, allowing power exchange among them to comply with demand limits, using a power management system to distribute power demands and ensure rapid charging without exceeding grid capacity.

Benefits of technology

The system effectively balances the vehicle and storage battery functions of electric vehicles, enabling rapid charging while adhering to power grid demands, eliminating the need for separate large-scale storage batteries.
