|Location||Brooklin, Maine US map|
|Vehicle||1974 Harley Davidson Aermacchi |
* SOLD - AUTUMN 2009 TO A FRIEND WHO'S STRIPPING THE EV COMPONENTS TO MOUNT IN A FULL-SIZE HARLEY SOFTTAIL FRAME
I was given this for cleaning up someone's shed; it was a rolling chassis with blown motor and I decided to stick the electric stuff in it as a proof-of-concept vehicle. H-D imported Aermacchi (an Italian manufacturer) during the sixties and seventies.
|Motor||Advanced DC 140-07-4001 Series Wound DC|
Really too small for this vehicle but it performs pretty well regardless.
|Batteries||3 Universal Batteries 12110, 12.00 Volt, Lead-Acid, AGM|
made best use of the space available for batteries.
|System Voltage||36 Volts|
|Charger||Iota DLS 42-18|
No temperature compensation but works well regardless (using zener regs.)
|DC/DC Converter|| |
|Instrumentation||Speedo, Westberg combo Volt/Ammeter|
|Top Speed||50 MPH (80 KPH)|
Motor is geared 5000 rpm = 50 mph. It's hard to do and really eats up battery life. The bike likes 35-40 mph a lot.
|Range||30 Miles (48 Kilometers)|
I've never gone further than 15 miles but resting voltage shows the batteries at 75% SOC. This at 30-35 mph. There's a lot of rolling hills around here.
|Watt Hours/Mile||125 Wh/Mile |
I keep track of A.C. Whr/Mile using a Kill-A-Watt meter. DC numbers would be smaller.
|Seating Capacity||1 adult|
|Curb Weight||400 Pounds (181 Kilograms)|
Battery weight is about 50% of total vehicle weight.
|Conversion Time||3 months|
|Additional Features||I used to carry the charger with me but I think the potholes around here made it fail. I never needed to charge on-the-go anyway.|
Workmanship isn't that good but the bike is functional and very reliable.
|The only disadvantage of not mounting the charger on the bike is that when it's plugged into the batteries after a ride, it has never registered that they need a Bulk charge i.e. battery voltage after stopping is above what the charger needs to see in order to start bulk charging. I have to turn the system on and whack the throttle open while holding the front brake in order to force a voltage drop that the charger sees; this enables proper charging!|
