ActiveOff-cycle technology/device energy saving effects evaluation methods for passenger cars—Part 4:Regenerative braking system
乘用车循环外技术/装置节能效果评价方法 第4部分：制动能量回收系统
Application Summary AI generated
This standard specifies the evaluation methods for quantifying the energy-saving effects of regenerative braking systems in passenger cars under off-cycle conditions, meaning real-world driving scenarios not fully captured by standard test cycles. It is applied by automotive manufacturers and regulatory bodies in China to assess and certify the fuel efficiency or electric range benefits of regenerative braking technology for compliance with corporate average fuel consumption (CAFC) regulations. The standard provides a consistent testing framework for comparing the performance of different regenerative braking systems across various vehicle models and driving patterns.
