BMS Touchscreen

I've been debating mounting this monitor for the BMS for some time. First I wasn't sure if I'd keep it connected all the time or not. The original plan was to monitor the serial I/O going to it and then take that data and turn things like the capacity into something for my fuel gauge. I also wasn't sure if I'd even stick with this BMS system or replace it with something better. After looking around I'm just not excited about any of the other BMS systems, especially not for the cost of something that does more. Now that I've added my own cell balancers the system I think is going to meet my needs perfectly.

OK, so for the first time I got so caught up in trying to figure out the best way to do this and make it look clean that I forgot to take pictures of the process. Sorry all.

I used 1/4" plywood and created frame about an 1/16" wider on each side, so 1/8" wider/taller total. This is to allow room for the monitor to still fit after wrapping the foam and leather material around the sides. The frame is shorter on one side so the monitor tilts towards the driver and to compensate for the curving dash. The front side is easy since it's all squared up, but the backside took a few attempts to get the curves just right to match the dash.

After the frame was complete I took and wrapped the outside with a very thin foam using a spray adhesive to attach it. Next I wrapped it with a synthetic black leather material to try and somewhat match the natural look of the car.

Finally I screwed some L shape brackets into the frame (two on each side) and finally screwed the frame into the dash. This part killed me and was probably the biggest delay factor. I really didn't want to screw anything into my dash!

The wires are ran behind trim/panels up in behind the dash poke out through a small hole I made just above the radio and below the BMS monitor.

Here is a picture of the final product from the driver seat.


Another shot from the passenger seat. You can see a little better here how the back needed to match the contour of the dash. It's not perfect, but I'm happy with the results.


Of course after completing the install I had to take it for a spin. It was very nice having this information at quick glance and is going to really help my driving to easily see the amp loads. This quick little spin puts me up to about 280 miles so far. I keep checking at work and things are moving along on the plug install. Looks like it was a pretty big job to get power from the main panel out to the parking spots. It's scheduled to be finished this Friday so I might be driving to work finally as soon as next week. If not, it shouldn't be much longer. I can't wait!
