AmeP has been including a Cycle Analyst (website below) which shows power used, as well as real-time consumption, including kW rate. The CA also has a Hall sensor input, and a scaling factor to allow for the motor speed to be displayed. The Cycle Analyst comes in two size formats, a pre-packaged unit suitable for bicycle use with a small display, and a component version featuring a large format screen. Use a Budd box with a clear cover from Allied to mount the component version for a robust battery monitor you can stow when sailing. Keeping the display inside when not in use (about 99% of the time) will extend its life tremendously. Sevcon makes a very nice display unit available with both Electric Yacht and Propulsion Marine systems. Motor and controller temps, as well as programming features are also included. Should AMeP incorporate a CANbus data line, I'd use the Sevcon displays in a heartbeat. For our current systems, and the majority of home-built installs, the Cycle Analyst does a adequate job. http://www.ebikes.ca/drainbrain.shtml is the home page for Cycle Analyst. (Drain Brain was the old moniker). Be Well, Arby Bernt Advanced Marine electric Propulsion --- On Fri, 7/1/11, Myles Twete <matwete@comcast.net> wrote:
