I am happy to share with you my progress in my DIY E-Bike (with a 1000W Golden Motor kit). Recently I was working in adding an Arduino Nano with an accelerometer to sense movements, so this way:
- I can sense if the bike was forgotten switched ON, so it can switch off automatically to save battery.
- When not in use in the street, I can sense every second if there is a suspicious motion, so the alarm can be activated after a prudential time with a high decibeles buzzer, like a car alarm.
- With a transistorized RGB LED (PL-9823), I monitorice battery with colors, from intermitent red (discharged) to violet (overcharged).
You can see the complete project in my blog page (translated with Google): http://crecimiento-sostenible.blogspot.com.es/2017/01/improving-ebike-with-arduino.html
(missing scheme, I will post it later). (More in the E-bike label).
I am looking to improve it with a little 1,3" OLED display 128X64 (witch can be easily waterproofed covering it with epoxi glue in the circuits side) to show more info, like, just brainstorming:
- Battery percentage in graphical way,
- Amperes or Watts (with a 100A hall sensor like the Allegro ACS75x),
- Battery and/or motor temperatures,
- Speed with a hall sensor in the wheel probably... (I don't know how exactly, maybe there is a built circuit for this) ... I am thinking on using the hall data that feeds the BAC-281 controller, but it could excede my electronics knowledge...
Just some ideas... what do you think? Any ideas or projects that already had this solved and improved? I can't find any open project as complex as this... to avoid duplicate efforts...
Sorry for my english mistakes, and happy new year from Spain!
