Abstract

In this paper, the authors describe a conformance testing system for SGSF-064-1, the communication protocol between electric vehicles and conductive DC (direct current) chargers in Korea. Since the SGSF-064-1 is based on CAN (controller area network), the testing system was developed by CANoe. The DC charger known as EVSE (electric vehicle supply equipment) is the system being tested and the developed system implemented in PC (personal computer). The developed system performs as a tester to ensure that the DC chargers from various manufactures can conform to the communication protocol in SGSF-064-1. The testing system contains four testing modes which also consist of several test cases.

Highlights

  • Electric vehicles (EVs) were once popular in the late 19th century and early 20th century before cars with internal combustion engines became available

  • This paper developed conformance testing for the Smart Grid Standardization Forum (SGSF)-064-1, which is known as the Korean standard for the communication interface of EVs and electric vehicle supply equipment (EVSE) for fast DC charging

  • This paper implemented a conformance testing system for SGSF-064-1 based on CANoe software

Summary

Introduction

Electric vehicles (EVs) were once popular in the late 19th century and early 20th century before cars with internal combustion engines became available. Several standards dictating the charging methods are available worldwide [1] Both electric vehicles (EVs) and electric vehicle supply equipment (EVSE), known as EV chargers, should be manufactured according to the industrial or organizational standard such as the International Organization for Standardization (ISO), International Electrotechnical Commission (IEC), and Smart Grid Standardization Forum (SGSF). This paper developed conformance testing for the SGSF-064-1, which is known as the Korean standard for the communication interface of EVs and EVSE for fast DC charging. The software implemented for conformance testing with CANoe can be used commercially to assess the conformity of EVSE made according to SGSF-064-1. Testing software used for developing the proposed system, CANoe, is the topic of Section 4.
