电动汽车国标充电口发展分析

Development Analysis of National Standard Charging Port for Electric Vehicles

电动汽车的国标充电口自上市以来,存在占用空间大、充电功率低等问题。通过列举国际主流充电口的发展情况,结合具体车型充电口的设计分析,提出未来国标充电口的4种发展方向,如采用联合充电系统、快慢充一体应用以及开发下一代充电口等,可以有效解决目前存在的如充电温升高、用户使用不便利以及和国际充电标准不能兼容等问题,为后续充电口的开发起到指导作用。

Since the national standard charging port of electric vehicles was put on the market, some problems have been figured out, such as large installation space, low charging power, etc. By enumerating the development of international mainstream charging ports and combining with the design analysis of charging ports for specific vehicle models, four development directions of future national standard charging ports are proposed, such as adopting combined charging system, integrated application of fast and slow charging and development of next generation charging ports, etc., which can effectively solve the existing problems such as charging temperature rise, inconvenient use and incompatibility with international charging standards, etc., and will play a guiding role in the development of subsequent charging ports.
