ActiveOff-cycle technology/device energy saving effects evaluation methods for passenger cars—Part 5: Generator
乘用车循环外技术/装置节能效果评价方法 第5部分：发电机
Application Summary AI generated
This standard specifies the test methods and calculation procedures for evaluating the energy-saving effects of high-efficiency generators used in passenger cars, specifically under off-cycle conditions not captured by standard driving cycles. It is applied by automotive manufacturers and testing agencies to quantify fuel consumption reductions from advanced alternator technologies, such as variable-voltage or smart charging systems, for regulatory compliance and eco-labeling in China. The standard supports the assessment of generator efficiency improvements in real-world driving scenarios beyond the New European Driving Cycle (NEDC) or China Light-Duty Vehicle Test Cycle (CLTC).
