| Vehicle | 1980 Kawasaki KE-175 This rolling frame was salvaged from a local scrap yard for 20 bucks. I hope to use it as a test bed for testing a variety of motors, controllers and battery combinations. | ||
| Motor | Unite Motor MY1020 - 750W Gear reduced *Rewound Jan 2008 Permanent Magnet DC This is a 4 brush 0.5 Ohm motor wound with 0.030" (AWG #20-21) wire. It has had the front casting drilled out to accommodate active cooling as the voltage is incrementally bumped up to twice it's rated value at 72V The motor has under gone 3 diffrent rewinds | ||
| Drivetrain | For now the motor is an internally geared 9 : 60 reduction unit that drives a 10 tooth sprocket and a 44 tooth wheel sprocket. The motor is rated as 750W, but is being drive @ 48V/50Amps. | ||
| Controller | Yi Yun YK42-x w/Custom Brute Force x-Tender brd (BFx) The controller is completely gutted and reworked to be quite flexible 48/60/72V at 13.3/26.6/40/100Amps depending on how you populate the BFx. Complete instructions, schematic and PCB layout at the link below... WebPage | ||
| Batteries | 4 Portalac SLA, 12.00 Volt, Lead-Acid, Gel These are identical to the Portalac specs but are branded under the CCell name. Each battery is rated at 18Ah. | ||
| System Voltage | 48 Volts | ||
| Charger | Yi Yun 48V 3Amp Very basic Fan-cooled Auto-Shut-off Charger... All Yi Yun parts, & controls are from TNC Scooters... | ||
| Heater | the under rated MY1020 motor as it's tortured in the shop... | ||
| DC/DC Converter | No plans to add at this time... | ||
| Instrumentation | Analog Battery Voltage (expanded scale 62V to 82V), analog Amp Meter (0 - 40Amp)and a Temp sensor for the motor. Garmin Fore-Runner 201 GPS (designed for athletic training, but usable of EV Evaluation. | ||
| Top Speed | 15 MPH (24 KPH) At this stage it should have a top speed between 15 to 20 Mph, at it's present gearing, though low end torque for hill climbing is more-so what it is geared for. | ||
| Acceleration | The first tests look very good as it has a bit of snap to it, though as it was tested on snow and ice, I don't have any accurate numbers given that the rear wheel tend to spin out as the throttle is cracked open. | ||
| Range | 7 Miles (11 Kilometers) over steep terrain and tall grass | ||
| EV Miles |
| ||
| Seating Capacity | one skinny butt | ||
| Curb Weight | 250 Pounds (113 Kilograms) The rolling frame was approx 120lbs, there is about 75lbs of lead, and another 20 to 30lbs of misc hardware. | ||
| Tires | rear tire is nearly bald (24" outer dia) | ||
| Conversion Time | about 2 months of periodic work | ||
| Conversion Cost | under $1000 so far | ||
| Additional Features | Given that the rolling chassis was missing lots of parts, a fair amount of time was spent fixing the brakes, and fabricating parts from scratch ie; brake control levers, foot pedal etc. | ||
| The BFx controller is a major step forward, but the MY1020 motor will require significant modification to stay with this project or be replaced. | |||
