Vehicle | 1980 Volkswagen Vanagon People mover | ||||||||
Motor | Azure Dynamics/Solectria AC55 3-Phase AC Air cooled. Motor controller max shaft power is 65kW (87 Hp). Stock vehicle was 67Hp. | ||||||||
Drivetrain | Standard 4 speed transmission | ||||||||
Controller | Azure Dynamics/Solectria DMOC 445 Air cooled | ||||||||
Batteries | 110 CALB/Skyenergy SE60AH, 3.30 Volt, Lithium-Ion 60 Ahr, sags to about 340V under around 150 amps. eLithion BMS system. About 21kWh. | ||||||||
System Voltage | 364 Volts | ||||||||
Charger | Manzanita Micro PFC50 Probably a little overkill, but I can sure charge fast. | ||||||||
Heater | 2@1500 W PTC heaters. About 5.5 amps at low fan and 9 amps at high fan. | ||||||||
DC/DC Converter | Vicor V375A15E600BL 600 W, brick. Raw device, have to add a number of items to make it usable. | ||||||||
Instrumentation | V and I gauges. Rabbit micro recording serial output DMM's (TP4000ZC), its onboard ADC and the BMS serial output. Data sent to an LCD as well as Wifi so that the iPhone can be used as a display. | ||||||||
Top Speed | 75 MPH (120 KPH) Keep it slow to conserve batteries but can hold with traffic fine. | ||||||||
Acceleration | Can be peppy now that I shed 900 lbs going from lead to lithium | ||||||||
Range | 60 Miles (96 Kilometers) Longest drive so far with the new batteries is about 54 miles with zero notice of a change in voltage sag (freeway driving) | ||||||||
Watt Hours/Mile | 450 Wh/Mile Wall-to-wheel. Battery to wheel varies between 350 Wh/mi to 420 Wh/mi, without regen on freeways. In city with regen will be much better. | ||||||||

Seating Capacity | 7 | ||||||||
Curb Weight | 3,800 Pounds (1,727 Kilograms) Vehicle weight with lead was 4700 lbs, so lost 900 lbs going with lithiums. | ||||||||
Tires | LT215/75R15, 50 psi, 100/97R, Load Range C. Eventually will change to smaller dia and narrower. | ||||||||
Conversion Time | 9 months official start to first drive, but more months to get the bugs out. Its a hobby. | ||||||||
Conversion Cost | ~$20k. Could have been less, but I now I am well stocked on bits-n-pieces for the next conversion. | ||||||||
Additional Features | Battery boxes sunk into body for minimal intrusion into passenger area, and to give lowest CG. 4.3kW of solar on my roof gives about 5000 kWh/year. 12,000 miles @ 450Wh/mi consumes about 4700kWh/year. | ||||||||
Lots of fun, lots of work, lots of getting yelled at by my wife for $$'s and time. |
