The EV Box is an open-source electric vehicle modular instrumentation platform. That's quite a mouthful.
Problem:
Electric conversions are an exciting DIY project whether it's an electric longboard or an electric car. They all have the same 3 systems:
- battery
- controller
- motor
From there you optionally need an input (throttle) and an output (voltmeter/ammeter). It's the output side of this equation that the EV Box will attempt to solve. Some motor controllers can't output data to a display on its own. Most either don't even try or require a PC to be connected to the controller. The EV Box will serve as the ultimate EV dashboard.
Application
Imagine a box called the TachBox. Have a hall-effect tach? 2-wire? 3-wire? A rotary encoder? 2 pulses? 4? 10? None of that matters. The TachBox will have screw terminals on one end to accept whatever tach you have. On the other side is a cable that plugs directly into the screen (DisplayBox) or the main head unit (BrainBox).
Example applications:
Electric Bicycle
-BattBox (battery voltage and current measurement)
-DisplayBox (screen)
-SatBox (GPS module for speed)
Electric Lawnmower
-BattBox (battery voltage and current measurement)
-VoltBox (simple LED bargraph display of battery voltage)
Electric Motorcycle (simple)
-BattBox (monitor traction battery)
-BattBox (monitor 12v system battery or converter)
-DisplayBox (screen)
-TachBox (RPM calc) (front wheel)
