Description

Technical Field

[0001] This utility model relates to the field of electric vehicle charging technology, specifically a new type of charging pile that combines multiple standards. Background Technology

[0002] With increasing global awareness of environmental protection and government support for new energy vehicles (NEVs), the electric vehicle market is experiencing unprecedented growth. Different countries and regions have varying requirements for charging stations due to their unique power infrastructure, grid standards, and consumer demands.

[0003] Currently, major economies worldwide, such as Europe, the United States, Japan, and China, have each developed different charging interface and communication protocol standards. For example, Europe uses the IEC 61851 standard, while the United States uses the SAE J1772 standard. In Japan, the CHAdeMO standard is widely used, while in China, the GB / T standard is the mainstream. This means that for a charging station to be universally accepted in the global market, it must be compatible with multiple standards to serve various brands of electric vehicles. Furthermore, traditional charging stations often rely on three-phase AC power, which may be difficult to implement in some areas, especially in regions with limited power resources or grid capacity.
