摘　　要：随着近年来新能源汽车渗透率进一步提高,直流充电作为快速补能方式的重要性愈发凸显。目前,针对不同的补能场景,电动汽车的直流充电方式主要有直流充电、大功率直流充电、小功率直流充电。文章通过对乘用车、商用车、充换电运营等15家企业的产品及技术规划的深入调研,结合标准发展、国家及地方政策、宏观形势,分析得出电动汽车直流充电发展方向:大功率直流充电将主要用于高端车型;小功率直流充电场景将在特定场景发展,如服务商、小区公共直流充电场景等,并根据V2G技术的普及情况发展;从充电功率方面来看,车企的车型开发将逐渐升级为支持180 kW以上充电功率的车型,桩企主流的充电功率也将提升到120 kW~180 kW,同时配备240 kW、360 kW的更高功率的充电桩。As the permeability of new energy vehicles has been further improved in recent years, the importance of DC charging as a fast energy replenishment method has become increasingly prominent.At present, according to different energy supplement scenarios, the main DC charging modes of electric vehicles include DC charging, high-power DC charging and low-power DC charging.Based on in-depth research on the product and technology planning of 15 enterprises such as passenger cars, commercial vehicles and electric charging operation, combined with standard development, national and local policies and macro situation, this paper analyzes and concludes the development direction of electric vehicle DC charging:High-power DC charging will mainly be used for high-end models;Low-power DC charging scenarios will be developed in specific scenarios, such as service providers and community public DC charging scenarios, and will be developed according to the popularity of V2G technology.In terms of charging power, the vehicle model development will gradually upgrade from models supporting charging power of less than 100 kW to models supporting charging power of more than 180kW.The mainstream charging power of pile enterprises will also be increased to 120 kW~180 kW, and charging piles with higher power of 240kW and 360kW will be equipped.
