Title:
NEW-ENERGY CHARGING SYSTEM, AND ALTERNATING-CURRENT CHARGING PILE AND CHARGING METHOD THEREFOF
Document Type and Number:
WIPO Patent Application WO/2023/024774
Kind Code:
A1
Abstract:
A new-energy charging system, and an alternating-current charging pile and a charging method thereof. The charging method comprises: when an alternating-current charging pile is in a power-following mode, measuring an available input power of a system where the alternating-current charging pile is located; when the available input power is greater than or equal to a single-phase threshold value and is less than a three-phase threshold value, controlling the alternating-current charging pile to provide single-phase charging for an electric vehicle by means of a charging gun of the charging pile itself; and when the available input power is greater than or equal to the three-phase threshold value, controlling the alternating-current charging pile to provide three-phase charging for an electric vehicle by means of the charging gun of the charging pile itself. In the charging method, the output power of an alternating-current charging pile is adjusted by means of adjusting the number of charging phases, such that the output power of the alternating-current charging pile follows an available input power, thereby achieving the optimal energy efficiency and also achieving carbon balance.
