摘要

目前的電動車普遍都有行駛效率低與電池壽命短的缺點，而造成這些問題主要的原因是電動車在行駛時，電池長時間以超過電池額定電流的方式在放電。為了解決輸出電流過高的問題，目前市面上的電動車都是利用控制馬達跨壓的方式來抑制電池過高的輸出電流；而本文希望藉由在電動車上安裝一組排檔裝置的方式，抑制電池過高的輸出電流，並且依照不同行駛路況下的電流值，選擇適當的檔速行駛。

Due to discharging for battery is usually over its rated current, a electric scooter has problems of low driving efficiency and short life of battery. Especially, a battery's output current is much higher when a electric scooter is drove on a ramp. In order to solve above problems, people are used to reducing voltage of motor to control battery's output current. However, it's confirmed by an experiment that reducing motor's voltage can't improve driving efficiency of a electric scooter. Therefore, I choose to install an Automated Manual Transmission on a electric scooter to limit battery's output current and depend on the value of current to choose a suitable gear ratio to drive.
