초록 |
Sales of electric vehicles have been dramatically increased by the ambitious policy with subsidies worldwide. EVs a t the early market h ad low-grade r anges, s o a single-cycle test(SCT) w as e nough to u se EV test at first. In order to reduce lab test duration, a multi-cycle test(MCT) for EV with over 200 km range was introduced. In recent years, EV technology with battery energy density has significantly progressed in order to attract more customers that prefer long-range EV. However, it would necessitate more time and cost with the rising test duration. The purpose of this study is to propose revised MCT methods for solving this problem along with the general test requirements, such as repeatability, reproducibility, and reasonable cost. The improved MCT methodology is introduced in order to reduce the lab test burden, and the main principle is to eliminate an urban dynamometer driving schedule(UDDS) on the test sequence. Two EVs were tested in order to verify the test requirements of the improved methodology by MCT and three revised MCTs. All test results compared three revised MCTs with MCT. The results showed less than 1.6 % difference of energy consumption, at most 1.8 % difference of energy efficiency, under 1.4 % difference of range, and time saving up to 23 minutes. |
