Vehicle2009 Solar-Electric Catamaran
Jerry Dycus built the boat (813) 671-3059 10011 echo MtnDr, Riverview Fla 33569 in 09' to be very efficient with electric drive and I added all the electric stuff. If you want one, it's approx $14k
Motor Vector 3X MK-101 Minnkota Permanent Magnet DC
I put a Minnkota on to be quick but will probably build a outboard like Ray Outboards or direct drive shaft with a 2:1 prop reduction
DrivetrainMinnkota MK-101 biggest trolling motor they make with 4" pitch prop (with winglets)
Controller Mark's Special
600A PowerEx IGBT from Ebay, a clump of caps (9kuF 100V) and 400A diode on smashed flat 3/4" copper water pipe all inside an grey steel electric utility enclosure (Hoffman or equiv)
Batteries32 Thunder Sky 100AH (in buddy pairs), 12.00 Volt, Lithium-Polymer
200 lbs weight that replaced the 200 lbs 4 marine batteries 80ah, doubled range (depending on speed), typical 15 miles at 80 amps at 7mph.
System Voltage48 Volts
Charger Mark's Special
Converter microwave oven transformer with 25uf 250vac motor run HVAC cap across the primary for PFC. The secondary was replaced with #14 wire for 2A final taper at 2.58V per cell in a push pull center tapped fashion using two 50A diodes. I used a MC68908QY4 uP for the standard charging algorithm, .01 V per cell per hour = stop (dv/dt=0)
DC/DC Converter Murata modified
48V to 12V Murata Telcom point of service type 4:1 converter from Digi-Key, Allied or Newark. Cigarette lighter for access is connected to a battery tap 20A fuse for intermittent high current loads (blowing up water toys without popping dc-dc converter)
InstrumentationCurtis 900R E-F meter, 100A meter, 50V meter, digital readout on charger from microprocessor. (See schematics on EVDL that Dave Roden put up) EVlist archives
Top Speed10 MPH (16 KPH)
Twin catamaran hulls designed for best electric propulsion efficiency and to hold 8ea 500lbs worth of GC batts (although I'm using lighter marine's at this time but 3 hours run time instead of 7)
AccelerationGrandma would be happy
Range15 Miles (24 Kilometers)
typical 15 miles at 80 amps at 7mph.
Watt Hours/Mile1440 Wh/Mile
Seating Capacity8
Curb Weight650 Pounds (295 Kilograms)
Tires2 trailer tires on trailer
Conversion TimeJerry 9 months, Me 2 months
Conversion CostAbout $14k
Additional FeaturesTwo 180W Evergreen 54 cell panels for float charging 24V per panel 2 centertapped battery pack
Lotsa Fun
