Re: [Electric Boats] Re: conversion performance

Hi Bob,

Our wiring harnesses from ElectroProp include an extra CAN port next to
the Sevcon Display connector. A PC (or raspberry pi) could easily
connect there with a USB-CAN interface.

A CAN to SignalK converter would be quite useful. Plugging into the
Sevcon's CANbus port woudl allow us to retransmit the info to the boat's
SignalK layer where it can easily be integrated with the NMEA data and
useful information can be logged and displayed.

My lithium pack's BMS and battery charger are not CANbus unfortunately,
but if they were, they would also be able to pitch the information up to
SignalK.

My Battery SoC meter has a serial data output by way of a USB port. It
just spits out a formatted string of ASCII text each second. I've got
that connected to an OpenWRT router's USB connection (see
http://VoCore.io) and currently just log the data with a timestamp for
off-line integration with my logged (http://stripydog.com/kplex) NMEA
data.

All the "intelligence" should happen with data read from SignalK,
instead of from disparate NMEA, N2K, SeaTalk, serial, CAN, etc. The
next couple of years are going to tbe very exciting in the marine
electronics and data spaces.

Cheers,

/Jason
