|Owner's Other EV||1972 Volkswagen Van|
|Location||Colorado Springs, Colorado US map|
|Vehicle||1973 BMW Slash Five |
Made up from 1994 Ezgo golf cart rear axle/motor
unit and BMW frame, seat, front end. Joined
with a steel plate subframe I had made at a
|Motor|| Series Wound DC|
8HP after market Golf Cart motor.
Pulls 150 Aps on take off, settles into 50 to 70
Alltrax Golf Cart Controller,
Input from 0 to 5K pot throttle
|Batteries||2 Deka 100AH (2 X 50AH), 48.00 Volt, Lithium-Ion|
I replaced the 6 8-volt batteries with four
12 deep-cycle batteries. Lost a bit of range
and gained a LOT in handling!
Update - 2016 - I purchased a pair of Lithium-
ion Chevy Volt batteries. What a difference!!
I really have not determined the range yet but
they seem to be much stronger than the
previous lead-acid ones. Going from approx
280 lbs to 80 lbs sure made a difference as
|System Voltage||48 Volts|
|Charger|| 48 volt GC charger|
Plugs into 110 volt AC outlets
|DC/DC Converter|| |
|Instrumentation||Motive Battery Voltmeter (cheap VOM)|
Aux Battery Voltmeter
0 to 200 Ammeter with shunt
Sigma bicycle speedometer with sender on front
|Top Speed||30 MPH (48 KPH)|
25 to 30 on flat roads
Slows to 18 on steep hills
Up to 35 going down steep hills, I try to keep
it below 35 to preserve the motor
|Acceleration||Great to 20 MPH!|
slow after that
|Range||35 Miles (56 Kilometers)|
This is to 75% DoD (Depth of Discharge)
We'll see how the lithium-ion batteries do....
|Seating Capacity||1 adult|
|Curb Weight||620 Pounds (281 Kilograms)|
420 of that is batteries! Then down to 280 lbs
and now down to 80 pounds with the Li-ion ones.
|Tires||Honda emergency spare tire/wheel units|
13" diameter. I found a pair of 14" wheels and
have them in place. I have to say, I can't tell
any difference in speed.
|Conversion Time||three months|
|Conversion Cost||$1500 plus old BMW motorcycle parts I already |
|Additional Features||LED Headlamps.|
I updated the LED headlamps (circa 2007) to a MUCH more powerful set
|There is a lot more available to the experimenter today (2016) then |
when I built the vehicle. The Li-ion batteries are the big
improvement but I am also updating the voltmeter and headlamp. It
remains a FUN vehicle to ride around town on on a warm day.
