ArduBike 250W, an Arduino-Based E-Bike Controller

Arduino Mega 2560 Rev3

<p >I am using a basic entry level e-bike for my daily transportation around town. The original controller was having some flaws, so I changed it with a other Chinese model, so learned about signal names like PAS (Pedal Assist) and found out that I could add a throttle, because the new controller supported it. Now I like my e-bike very much with the throttle... Becoming gradually more familiar with the technology, I tried to write my own controlled software based on a Arduino Mega 2560, first to learn how the BLDC drive works, second to be able to add any feature I want. Because I wanted not to rebuild the hardware from the power stage, I took a Chinese controller, removed the processor and soldered the six wires to control the H-bridge. Those six lines are now controlled by the Arduino.</p><p >The result works surprisingly well, as you can see in this video.</p><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/1RqtnPTJsDA" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe></figure></div><p >OK, I could not make a &#34;field test&#34; because the hardware is no reliable enough to build it in the bike and drive on the streets.</p><p >Would be nice to have more enthusiasts help to design a hardware shield for this project and produce a few PCBs. People interested should contact me. I can provide schematics and component listing for a shield...</p>
