| 摘要: |
| 目前电动汽车充电桩对用户的认证结算方式千差万别，大大降低了用户充电操作的便利性和安全性。针对这个问题，给出了一种能用在各种充电桩上的新型认证结算单元。其设计理念是将充电桩分为充电控制单元和认证结算单元两部分。其中充电控制单元主要负责充电控制和与车辆通信等功能，认证结算单元主要负责人机交互、用户认证、计量计费、结算支付和远程通信等功能。简单介绍了认证结算单元的整体设计方案、硬件结构和软件结构，详细阐述了双向认证、充电启动、中止充电结算和充电完成结算等主要业务的实现流程。通过实践证明该设计形成了标准的充电操作流程，有效地规范了用户认证结算方式，大大提高了用户充电操作的便利性和安全性。 |

| Abstract: |
| Currently, the user's certification and settlement methods of different electric vehicle charging piles vary widely, which greatly reduces the user charging operation convenience and security. Therefore, this paper presents a new type of certification settlement unit which can be used on various charging piles. The design idea is to divide the charging pile into two parts:the charging control unit and the authentication settlement unit. The charging control unit is mainly responsible for charging control and communication with vehicles. The certification settlement unit is mainly responsible for human-computer interaction, user authentication, metering and billing, settlement payment and remote communication. It introduces concisely the overall design scheme, hardware structure and software structure of the certification settlement unit, and describes the realization process of the main business, such as bidirectional authentication, charging start, stop charging settlement and charging completion settlement in detail. It is proved by practice that the design forms the standard charging operation flow and standardizes the users’ certification and settlement method effectively, which greatly improves the convenience and security of user charging operation. This work is supported by National Key Research and Development Program of China (No. 2016YFB0101800). |
