| Vehicle | 1978 Honda CB750K Purchased not running in northern Kentucky. Gave the motor to a buddy who has the same bike, was able to sell some parts such as the carbs to almost pay for the initial cost of the bike. | ||||||||
| Motor | D&D Motor Systems, Inc. ES-10E-33 Separately Excited DC Weighs about 53 pounds, puts out 31 HP peak. | ||||||||
| Drivetrain | Direct drive, haven't determined final gear ratio yet. | ||||||||
| Controller | Penny and Giles PGDT SigmaDrive SEM 72-80V 350A | ||||||||
| Batteries | 24 CALB/Skyenergy SE-40AH, 72.00 Volt, Lithium Iron Phosphate Going to be purchased from CALIB in Califoria. Slightly smaller than comparable to same capacity Thundersky but has higher discharge rates, but lower cycle life. | ||||||||
| System Voltage | 72 Volts | ||||||||
| Charger | Unknown 72V 3A Charger Purchased used for right now, plan on upgrading to a 72V 15A charger from Elite Power Solutions. Promises a 2.6 hour full charge for a 40AH 72V pack. Pretty quick! | ||||||||
| Heater | Wat?! | ||||||||
| DC/DC Converter | Sure Power Industries, Inc 71030i Really nice looking unit isolated, big fins for heat dissipation and feels very solid. Bought from Barefoot Motors. Haven't hooked it up yet so I don't know how it performs. | ||||||||
| Instrumentation | Large Display Cycle Analyst | ||||||||
| Top Speed | 70 MPH (112 KPH) Just a guess based upon the research I've done with comparable builds. Seems reasonable considering how much weight I'm going to manage to strip off the bike. We'll see, I wouldn't be too disappointed if top speed was a bit lower. | ||||||||
| Acceleration | Unknown, should be reasonably fun, though. | ||||||||
| Range | 25 Miles (40 Kilometers) Just a guess, based upon the research I've done and some rough calculations. | ||||||||
| Watt Hours/Mile | Will calculate when the build is actually finished. | ||||||||
| EV Miles |
| ||||||||
| Seating Capacity | 1 adult | ||||||||
| Curb Weight | 350 Pounds (159 Kilograms) Hoping for a final curb weight around 350 pounds. Managed to lose a bunch of weight by trimming the frame and using a fiberglass tail section and removing metal from the tank. | ||||||||
| Tires | Bridgestone Spitfires | ||||||||
| Conversion Time | A year thusfar | ||||||||
| Conversion Cost | I've got around 1000 sunk into the motor, controller, contactor, magura throttles, DC/DC converter, and charger. I estimate another 2,000 bucks on batteries and misc. bits and pieces. | ||||||||
| Additional Features | Plan on using MiniBMS to control HVC and LVC, as well as some basic cell-balancing functions. Also plan on using the Cell-logs from HobbyKing to monitor the voltage of each cell in real time. | ||||||||
| It's been a long, ongoing project due to several trips out of town and away from my build, not to mention school occupying more time than I initially anticipated. My goal was to keep the bike lean and light, with enough range and speed to cruise around the city comfortably. A big part of this project was not compromising the original look and feel of the CB750. I want it too look lean and fast, maybe even look like it came from the factory that way. I realize I could get more range out of it by going with a larger battery pack, but was unwilling to make the trade-off of looks and weight. I am making the batteries a focal point of this bike, not something that will be hidden under a fairing. The current layout of the batteries requires a single tray to be fabricated to hold the batteries and controller. | |||||||||
