台湾油耗测试就跟随欧盟(ECE R101)
NEDC行车型态组成
4个UDC(urban driving cycle) + 1个ECDU (extra urban driving cycle)
每个UDC测试时间195秒行驶约1公里，EUDC测试时间400秒行驶约7公里
总共1180秒行驶11公里

ECE R101第2版修正

Annex 8
Method of measuring the emissions of carbon dioxide, fuel consumption and
the electric energy consumption of vehicles powered by a hybrid electric
power train
其中RAV4属于NOVC(Not Off-Vehicle Charging)：不可插电的油电车(HEV)
6.
Not Externally Chargeable (notOVC HEV) with an operating mode switch
6.1
Emissions of carbon dioxide (CO2) and fuel consumption shall be determined
separately for the Part One (urban driving) and the Part Two (extra-urban
driving) of the specified driving cycle.
市区非市区的能耗/排放要分开
6.3.1
The test results (fuel consumption C [l/100 km] and CO2-emission M [g/km]) of
this test are corrected in function of the energy balance batt of the
vehicle’s battery.
油耗C/排放M都要经过修正
The corrected values (C0 [l/100 km] and M0 [g/km]) should correspond to a zero
energy balance (cted in function of the energy
In case of other storage systems than an electric battery, ΔEbatt is
representing ΔEstorage, the energy balance of the electric energy storage
device.
能耗需要以ΔEbatt修正，公式如下

6.3.1.1.
The electricity balance Q [Ah], measured using the procedure specified in
appendix 2 to this annex, is used as a measure of the difference in the vehicle
battery’s energy content at the end of the cycle compared to the beginning of
the cycle. The electricity balance is to be determined separately for the Part
One cycle and the Part Two cycle.
所以前面有篇回文说说充饱电再送测，还满好笑的XD
不过即使有经过ΔEbatt修正，只要电池容量较大，市区油耗还是会相当的好
因此ΔEbatt修正后的结果并不贴近实际使用情况
要比较类似实际使用情况，可参考美国EPA(Environmental Protection Agency)的结果
https://reurl.cc/qrjQD
市区/高速分别是41/37mpg(17.4和15.7 km/L)，与ECE的测试结果有着不小落差
结论
1. ECE油耗测试有经过ΔEbatt修正
2. 但ΔEbatt修正受到电池容量影响，与实际使用情况仍有落差
3. 比较准的能耗请参考EPA
