摘要

功率输入、速度和效率是人们在选择交通工具时关心的问题。本研究比较了多种电动自行车的配置，并向读者提供了科学的标准，以选择最适合非训练的骑自行车的人，他们希望在陡峭的道路上使用电动自行车进行日常交通，确保骑自行车的人有效地使用部分电力输入。功率发展、速度、能耗和效率是由数学模型和实验数据得出的。配置在电机位置、辅助水平、骑自行车的节奏、车轮类型和传动装置等方面有所不同。结果表明，电机的位置是决定整个系统效率的最重要因素。将电机置于底部支架，允许自行车手和电机在最有效的rpm范围内。由于中间驱动电机的效率高于轮毂驱动电机，因此轮毂驱动电机的能耗要高出18%。

E-bikes for steep roads: mid drive and hub drive motor efficiency comparison

Power input, speed, and efficiency concern people when selecting a transportation means. This study compares multiple e-bikes configurations and presents to the reader scientific criteria to choose the one that fits best for non-trained cyclists, who want to use e-bikes for everyday transportation in cities with steep roads, assuring that the cyclist takes effective part of the power input. Power development, speeds, energy consumption and efficiency result from a mathematical model and experimental data. Configurations vary in motor placement, assistance level, cyclist cadence, wheel type and transmission sets. Results indicate that the motor's placement is the most determining factor in the efficiency of the entire system. Placing the motor in the bottom bracket, allows both the cyclist and the motor to range in the most efficient rpm. As efficiency for the middle drive motor is higher than the hub drive motor, energy consumption in the hub drive motor is 18% higher.
