Since I seem to be one of the few happy Logisystem controller owners out here, (or is it just that the EVDL is skewed towards talking about problems so we rarely hear from the happy owners?) I'm starting to wonder what kind of service life I can expect to get out of my controller barring any catastrophic failure. I'm coming up on 3 years of faithful service already. I'm curious, because I would really love to invest in a lithium pack some day, but I would hate to spend the money on new batteries only to have some other major component fail.

My first controller made by Cable Form in England, was install in 1975 in m=

first EV and ran up to 2002 with no problems. These units cost $6000.00 =

back then and have three Cable Form 600 contactors that I am still running =

today in my second EV

I replace the Cable Form controller in 2002 with a Caf=E9 Electric controll=

because the service packs for Cable Form controller cost more than the Caf=

Electric controller which is still running up to the present with no =

problems.

Set it up in 2002 and never touch it again. It still maintain all its =

The life expectancy of your controller is directly proportional to how
hard you use it, and how close to the "limits" you operate it, how hot
it gets and so on.

What is your setup?

Mine is 72 - 120 volt 1000 amp. I have used it for packs ranging from 72 - 108 volts (108 for 50 - 60 percent of the time). If I do go lithium, I would probably drop back down to 72 - 96 volt range depending on what ahr capacity I choose. I only have instrumentation on my battery side, but accelerating from a stop draws around 300 battery amps sometimes up to 500 for very short bursts while most of my cruising is done at around 100 - 200 battery amps. I also have about 1 - 2 seconds worth of throttle ramp setup, so the initial acceleration is not full on. I also have a precharge circuit.

That seems fairly modest, as far as duty cycle and load is concerned.
The best indicator to tell how well the controller is handling that
amount of power is how hot is it getting after a run. Hot is bad. Too
hot to touch is real bad.

The higher voltage pack places more demands on any controller. A 108
volt pack is pretty manageable, in my experience.

(disclaimer: these statements are oversimplified)

Hi Damon
I have one I in our rav 4 over 2 years old that has a 156v 1k and
13 pc2150 (156v) pack . You didn't say what size motor you have , Mine
is an 8 " and I know of another Fastive with 108v and a 8" still
alive. You didn't say anything about your driving style . I never go
past 2 gear and will use 1st when taking off if there is any kind of
hill. I've seen 450 amp when motor rpm is at its sweet spot and I'm
feeling reckless . Do you have a clutch ,, I'll bet that would help,
Also is yours one of the old one's before they re did stuff? I also
have a 72v 1250 amp that is on a motor cycle and that I loaned to the
school kids for there go cart project , it's probable close to 3 years
and has even been in a few cars , it doesn't seem to get hot like the
others . It might be a good idea to replace the caps in any controller
after a certain amount of time , as the do go bad I've heard .
Logisystem just warrantied our last sale and I am grilling the owner
on how it is working , .

On the other hand ,, I've sold more Zilla's than I can remember and
that was all before Logisystem , a few have been repaired but all for
less that 100 dollars and all very quickly so I don't think much went
wrong. To bad he stopped making them as most that bought LS would have
gotten zillas , Things looks good with the new breeds out there , To
bad nobody has any money any more .

Damon,

I'm also one of those with a Logisystem controller who is happy with it. I
suspect you're right that we are only hearing from the few with
problems. I've had my 120-144V, 750 Amp unit for almost 2 years. Mine is
one of the new ones (made in Oct 2008 after they resolved the problems they
had).

To mirror Steve's details, I drive a 120V pack of 12V AGMs with a 9" ADC
motor. I use a clutch and the transmission sort of like it was
intended except I change gears far less often and shift at higher rpm (and
of course I don't "down shift" like in an ICE because there is no engine
compression). I always start in 1st gear. I shift from 1st to 2nd at 20
mph and (if I ever go that fast, but rarely do) I shift from 2nd to 3rd at
40 mph. When slowing for traffic I'll switch back into 1st gear if I get
much below 15 mph. The terrain here is quite flat (at least the area I
drive in) and the most I see is 250 motor amps even when starting out. 90%
of the time it's under 200 amps. I'm usually pulling about 90-100
motor amps at 25 mph and about 125 motor amps at 35 mph. Bottom line is so
far it's working fine.

btw - I figured out the shift points for my car using the formula provided
in Mike Brown's "Convert It" book by plugging in gear ratios and the final
drive ratio for my car and assuming 4500 rpm as max for my motor.
