| Vehicle | 1993 CityCom CityEl OEM Electric with modifications. | ||||||
| Motor | Thrige-Titan Triage 48V Compound Wound DC 36V nominal | ||||||
| Drivetrain | Poly-vee belt 260J13 (13PJ660) | ||||||
| Controller | Alltrax AXE 4865 650 amp 48V nominal Programmed to deliver 200 amps max to stay within grip limits of drive belt. Turns out to be plenty, especially at the higher battery voltage. | ||||||
| Batteries | 4 Sears DieHard Platinum PM-1, 13.40 Volt, Lead-Acid, Gel 90+ Ah 75 LB each EnerSys PC2150 AGM badged as Sears Die Hard Platinum PM-1. 4-year free replacement warranty. (one battery possibly reversed, but warranty not transferrable between owners) Upgraded to 48 volt system, 3 batteries in original battery rack, and one in the rear cargo area with steel strap and long threaded rods holding it in place. 48 volt pack tapped at 36 volts supplies the factory DC- DC converter, windshield wiper, and 2 heaters. Separate charger on each battery and 1 external booster for rapid charge compensates for the additional load on the batts in the 36 volt portion. (about 54V charging) | ||||||
| System Voltage | 48 Volts | ||||||
| Charger | Sears PC Power & Cooling Silencer 610EPS12V There are four Silence power factor corrected ATX computer Power Supplies and 1 external Sears DieHard charger/booster. As stock power supplies they can deliver 12.0 volts at 49 amps and 1 external Sears Platinum (2 to 125 amp charger or booster- 16.6 to standard/normal 13.1 to 40 (microprocessor controlled) volts. The great things: 1) better efficiency due to PFC 2) automatically accepts 100-240V 3) very quiet 4) lightweight (on-board chargers) 5) fast charging 6) one charger per battery 7) external booster is heavier and noisier, but not always necessary. | ||||||
| Heater | two 400W and fans | ||||||
| DC/DC Converter | factory | ||||||
| Instrumentation | Standard Dash, Battery low voltage alert, bike computer replaces annoying LED array simulating analog speedometer. Green "glow-light" light-stick. LED lights added outside also. | ||||||
| Top Speed | 50 MPH (80 KPH) Significantly faster acceleration with 48 volts instead of 36 volts at the controller input. I can now take the expressways! Less range, but keeps right up with fast traffic and zips up hills (motor does get pretty hot though). | ||||||
| Acceleration | 0 mph to 40 mph; 20 seconds - NO jackrabbit starts; steady climb in speed. Very governed to save belt! | ||||||
| Range | 20 Miles (32 Kilometers) Not getting original 35 mile range due to faster acceleration and double the top speed. | ||||||
| EV Miles |
| ||||||
| Seating Capacity | 1 adult (extra battery exceeds weight, higher gearing exceeds acceleration and top speed- 1 more passenger would be suicidal!!!) | ||||||
| Curb Weight | 825 Pounds (374 Kilograms) 4th battery, 4 chargers, tester, relays,etc. Normal is 630 pounds. Over all limits! | ||||||
| Tires | 3 Pirelli 80/70 16s - 2 back, 1 front | ||||||
| Conversion Time | Factory built, with significant modifications detailed below. | ||||||
| Conversion Cost | |||||||
| Additional Features | Drive ratio changed from original 7.2:1 to about 4.5:1 to increase top speed. New components: 1) Custom solid aluminum driven pulley with anodized finish. 2) Custom solid aluminum idler assembly to accommodate the new smaller driven pulley. 3) 260J13 poly vee belt. 4) More powerful (Alltrax) motor controller, current limited to 200A to prevent damaging stress to drive belt. Bike computer and interface (provides more accurate speed reading, average speed, better visibility at night than the stock glaring LED array) Recharge to 80% SOC is very quick, under 2 hours for a 20 mile trip, all from a conventional 20 amp circuit. Windshield wiper & washer, heaters, turn signals, headlight, brake lights, interior lights, stereo ; all work great! 3rd brake light on roll bar to enhance visibility. (2 additional 8 LED trailer lights for rear brake lights added recently) | ||||||
