Real Road Energy Consumption Analysis of Electric Vehicles in Typical ASEAN Countries

The export of new energy vehicles (NEVs) has become a crucial strategic direction for the high-quality development of China’s automotive industry. As a major market for China’s NEV exports, the Southeast Asian region highlights the significance of developing region-adapted automotive products to advance the high-quality growth of China’s automotive sector. However, most currently exported models are developed based on existing standards without full adaptation to the regional traffic characteristics of Southeast Asia, resulting in insufficient accuracy of adaptive calibration. To address this issue, this study focuses on Thailand, Indonesia, and Vietnam, collecting 5,577 km of real-vehicle road data covering multiple typical scenarios. Multi-dimensional analysis is conducted to reveal regional driving characteristics and energy consumption patterns. The results indicate that the driving characteristics of the three countries show the highest consistency with the China Light-duty Vehicle Test Cycle (CLTC), while energy consumption exhibits significant regional differences. Vehicle speed and acceleration are identified as the core influencing factors. This research provides key data support for the calibration optimization and energy consumption control of models targeting the Southeast Asian market, contributing to enhancing the export competitiveness of China’s NEVs.
