| Vehicle | 1981 Chevrolet El Camino DC motor system, clutchless 3-speed manual transmission with 200AH Lithium Ferrite Phosphate batteries (LiFePO4). | ||||||
| Motor | Advanced DC FB-4001A Series Wound DC | ||||||
| Drivetrain | 3 speed manual transmission (original) Rear End Ratio 2.73:1 1st Gear 3.50:1 9.55:1 2nd Gear 1.89:1 5.16:1 3rd Gear: 1.00:1 2.73:1 | ||||||
| Controller | Curtis 1231C-8601 | ||||||
| Batteries | 46 Thunder Sky LFP200AHA, 3.30 Volt, Lithium-Ion 200 Amp-Hour Pack: LiFePO4 Lithium Ferrite Phosphate | ||||||
| System Voltage | 144 Volts | ||||||
| Charger | Zivan NG-3 220 VAC at 16A input | ||||||
| Heater | Electric forced-air 1.5 Kw 150 volt 10 amp SOLID-STATE air conditioning (Peltier Devices) being installed August 2009 9 amps at 150 volts | ||||||
| DC/DC Converter | 30A DC at 14.4V with 17AH Gel Cell for backup | ||||||
| Instrumentation | 0-180 volts 0-500 amps 10-18 volts 0-50 amps Thundersky BMS reads every cell voltage, pack voltage and current, estimates watt-hours remaining ("Gas Gauge") | ||||||
| Top Speed | 85 MPH (136 KPH) Pegs the speedo | ||||||
| Acceleration | Surprisingly Quick for a 4000 pound truck | ||||||
| Range | 200 Miles (321 Kilometers) With careful city driving. 100 miles minimum with freeway and city mix. Not terribly hilly around here in Southeast Wisconsin... | ||||||
| Watt Hours/Mile | 200 Wh/Mile | ||||||
| EV Miles |
| ||||||
| Seating Capacity | 2 adults | ||||||
| Curb Weight | 4,000 Pounds (1,818 Kilograms) was 3266 before conversion GVWR 5003 | ||||||
| Tires | 205/70-14 | ||||||
| Conversion Time | Ordered parts March 2009. Most work done in two months with several months to plan in advance. Motor made in March 2009 died at 500 miles. Was replaced under warranty in July 2009. Delays from mechanical contractors kept her in the garage for 8 weeks, otherwise good to go. Man, this is FUN ! | ||||||
| Conversion Cost | about like a new car ! Batteries charger and BMS cost about $18K The rest was under $10K (so far) | ||||||
| Additional Features | Solid state air conditioning. Separate 1HP motor direct-drive power steering runs off pack voltage directly. Tachometer added by magnets and prox switch off tail shaft of motor. PWM (pulse-width modulation) of our own design controls heat, air conditioning, and power steering motor. Steering motor on with pedal only during movement, cuts out over 30 mph (not needed). Many features will be revealed and explained that are under development now. Safety: crash switch, dual series contactors (key and pedal), fusing EVERYWHERE, lockouts for charger plugged in, high pedal disable, backup power for critical systems. Extra 144 volt 17AH pack in cargo bay (under bed and behind seats) gives about 10 mile range for emergency. All technology will be made available to others on request for personal use. We love EVs ! Dual 4/0 cables (4 wires) connect front and rear packs to minimize voltage drop at high currents. We achieved our goal of 1 volt per 500 amps in the wiring! | ||||||
