Nissan Leaf SOH display frame

myminifactory

The first generation Nissan Leaf (2011/2012) has a notable limitation: its battery State of Charge is not displayed on the dash, although later models do show this information. This project aims to replicate that feature by adding a small OLED display inside the top dash. The 3D print files provided create a frame that holds the OLED in place and conceals the PCB. Three different frame designs are included: one for each of three display options - a 0.96 inch, 128x64 pixel OLED display in horizontal orientation, a 0.96 inch, 64x128 pixel OLED display in vertical orientation, and a 1.54 inch, 128x64 pixel OLED display in horizontal orientation. The display is controlled by a small Arduino Pro Mini board that communicates with a MCP2515 CAN Bus module, which connects to the Leaf's OBD2 port. Full details and software are available on my blog at http://www.myonlinediary.com/index.php/Energy/SOCDisplay. I will soon add a frame for a 1.3 inch OLED display. You may notice that it is difficult to see the frame in the picture provided - this was intentional, as the frame serves its purpose by blending into the surrounding area.
