Re: [Electric Boats] Re: Marine MFD that can read electric motor controllers

 

As I have a BMV-600 at the helm that shows Volts, current, SOC, and time to go, having this displayed on my MFD is lower priority. For me, what would be most useful to display on the MFD is motor and controller temperature, motor RPM, motor volts/current.  These pose more of a challenge due to there not being NMEA2000 PNGs for these parameters and the MFD not specifically configured to display EP type parameters. My Raymarine has, as I'm sure other MFDs do, a "Switch Panel" application that allows custom displays to be built on 3rd party software and then loaded to the MFD. I don't know much about this, the cost of the software or the ability to accomplish what I'd like to do. Anyone know about this?

This is a fascinating development having a NMEA2k option for Victron devices and systems. I read the manual and see that the Ah value isn't anything that most MFDs care about or understand. I haven't read the MFD manuals but wanted to know if you can parse and present data from proprietary PDUs to present onscreen?
I see that battery SoC and TTG (time to go) are reported in standard N2k format. How does the MFD present this data to you?

It looks like we could use a dual channel CANbus interface on Raspberry Pi to poll Sevcon and then repackage the information in NMEA2k to look like a normal engine burning MPGs or GPHs, so the MFD can estimate range.
