一种电动汽车充电协议的设计与实现

Design and Implementation of a Charging Protocol for Electric Vehicles

新能源汽车已成为世界主要汽车强国发展的国家战略,纯电动汽车(EV)则成为了主要突破口。在电动汽车充电标准问题上,主流的标准有ISO 15118和DIN 70121,中国于2015年底发布了新修订的《电动汽车传导充电系统》相关的充电系列标准,包括通用要求、交流充电接口、直流充电接口、通信协议等内容。针对电动汽车充电需求,本文设计了一种简单、易用的应用层充电协议,并在实际应用中验证了充电协议的功能。

New energy vehicle has become a national strategy for the development of major automotive powers in the world, and electric vehicle(EV) becomes the major breakthrough. In terms of EV charging standards, the mainstream standards are ISO 15118 and DIN 70121. Our country released the newly revised “Conductive Charging System for Electric Vehicles” by the end of 2015, including general requirements, AC charging interface, DC charging interface, communication protocol, etc. Aiming at the charging requirements of electric vehicles, this paper designs a simple and easy-to-use application layer charging protocol, and verifies the function of the charging protocol in practical applications.
