Hello everyone. I have completed building out a method to use the Valence HV bms and collect all of its data with some custom software. This software uploads the canbus data into a database that is then accessible via pre-built web page dashboard and mobile application for Android.
I want to be as transparent as possible, the hardware cost is made up of the following:
-Valence BMS and 2 contactors.
-Canbus usb adapter
-Dc buck Booster
-48v to 12v adapter
-Low power mini pc (This runs communication service, influxdb database and grafana.)
-Various connectors and plastic project boxes.
My estimate is that the material cost alone is $700 usd.
This is going to sound outrageous but my time is very important to me. I would need to charge around $1500 for this package.
I'm trying to see if I would have any interested buyers at this price?
Thank you.
