|---|---|---|---|---|---|---|---|---|---|
| Location | San Diego, California US map | ||||||||
| Vehicle | 1998 Volkswagen Golf sedan, white, 122K miles driven prior to conversion | ||||||||
| Motor | Azure Dynamics/Solectria AC24LS 3-Phase AC 85 lbs, air cooled, 47 KW peak, 92 Nm peak | ||||||||
| Drivetrain | AZD AC24LS AC motor, EA adapter plate, refurbished VW clutch, 5 speed manual transmission, FWD | ||||||||
| Controller | Azure Dynamics/Solectria DMOC445 Highly configurable using the serial port data interface. I customized the power levels, the regen points, the regen KW, the low battery power cut-back, and a few other tweaks. | ||||||||
| Batteries | 24 Fullriver DC55, 12.00 Volt, Lead-Acid, AGM Sealed, Maintenance Free, 55 AH rating, six under the hood, 18 in trunk. Custom battery box in the trunk help create a low center of gravity. | ||||||||
| System Voltage | 288 Volts | ||||||||
| Charger | Manzanita Micro PFC-20 20 Amps, 120 to 240 Volt AC input. Chosen for input AC Voltage flexibility and high DC voltage out. charging at 240 VAC is reasonably quick. recover about 10 miles of range in an hour. | ||||||||
| Heater | Ceramic cigarette lighter plug-in. un- tested during winter conditions. May install ceramic element inside dash at a later date. | ||||||||
| DC/DC Converter | Iota DLS-220-55 Originally designed for high AC to low DC voltage, but, proven good fit for high DC to low DC applications. | ||||||||
| Instrumentation | Westberg DC Amps, Pack Voltage, and Accessory Voltage. PakTrakr BMS of 24 batteries. | ||||||||
| Top Speed | 84 MPH (135 KPH) Accelerate in 1st gear up to 25 mph. cruise in 2nd up to 45 mph, 3rd gear beyond that. | ||||||||
| Acceleration | 0 to 30 in 6 Seconds. Zero to 60 in 25 seconds. Off the line is good and keeps me out of trouble. Patience and the right lane on the freeway allows me to cruise at sixty MPH. | ||||||||
| Range | 30 Miles (48 Kilometers) Depends on my driving habit. It's fun to zip around town in 1st and 2nd. I drive more carefully when I want more than 25 miles on a charge. | ||||||||
| Watt Hours/Mile | 280 Wh/Mile An in-car calculation of amps times volts results in (60A*280V)= 280 Whr/mi at 60 MPH - Level cruising in third gear. Otherwise, zipping around town and the hills of San Diego requires about 400 Whr per mile from the wall outlet. When my wife drives, it's more like 480! I'm using a P3 International Kill-a- watt meter upstream of my charger to measure. The 84 mph test run cost me 500 KWhr/mile for the recharge. | ||||||||
| EV Miles |
| ||||||||
| Seating Capacity | four passenger, four door | ||||||||
| Curb Weight | 3,000 Pounds (1,363 Kilograms) Removed 600 lbs of I.C.E. parts. Regained 200 lbs of motor, controller and other components. Gained 900 lbs of batteries. I look forward to continued price drops for Lithium batteries. That chemistry will be my next pack. | ||||||||
| Tires | Tiger Paw Touring, nothing special - just what was on sale. | ||||||||
| Conversion Time | Eight months of part time effort by Bob Van Gorder and several delays in acquiring parts and troubleshooting. | ||||||||
| Conversion Cost | Car with repairs and new tires: $4000. All Components, Parts, and Refurbishments: $15000. In general, AC systems are more costly than a DC system. Manzanita Charger, AGM batteries, and PakTrakr BMS also more than a bare-bones conversion. Reworked clutch. Upgraded rear springs to support added battery weight. | ||||||||
| Additional Features | Vacuum system for power brakes. Electro-hydraulic pump for power steering with ON/OFF switch on dashboard. PakTrakr Battery Monitor System. Regenerative Braking ON/OFF switch and Econ-Normal-Performance selector switch with Azure Controller on the center console. I use the switches a lot. Power level select to extend range when I don't need max power. PakTrakr is great for monitoring; but, not managing the battery pack. It has gotten out of balance over several charge and discharge cycle. Re-balancing one by one is a pain. In Dec 2009, I installed the Manzanita analog regulators for lead acid. $40 each for 24 batteries is a big Christmas present; but, necessary. After six months of charging with the battery regs, the batteries are getting a full and proper absorption voltage finish. The weak ones are hanging in there after earlier charging abuse. The majority of the pack is aging appropriate for lead acid life time estimates. | ||||||||
| Great collaboration working with professional installer, Bob Van Gorder, in Ramona California. Road tests started in April 2009. Great assist from Azure Dynamics for details of controller operations. FullRiver email tech support is very timely and comprehensive. More troubleshooting than expected, but, my EV grin is still very real. I am gaining a lot of knowledge on all aspects of this project and the components involved. Great Assistance from Ken Hall at PakTrakr, too. In March 2010, started charging from my 240V 30 amp outlet in the garage. Can now get to the thirteen amp charge for my DC55 batteries. They all get to proper AGM absorption voltage now and equalize nicely. Previously from my 120 V 15 amps. Could only get about 5 DC amps going into the pack. | |||||||||
