HI Paul.  I'm assuming here that you're using a series DC motor because I 
don't recall that GE made any EV1 controllers for separately-excited motors. 
I may be wrong about that, however.

But if your motor is series-field DC, and the  GE EV1 is indeed not among 
the living, and time is more important than the budget, the quick fix would 
be to replace the EV1 with a modern controller.  

I guess you could say that Curtis is a more or less "standard" choice here.  
They've been making road EV controllers for for many years.  Their former 
incarnation, PMC, built the DCC-96 bipolar transistor controller used in the 
Bradley GT EVs in the late 1970s.

Something like a Curtis 1238E-6521 (rated for 48-80v systems) should be 
plenty to get your car rolling, assuming you have a 60v battery, which your 
message suggested.  

There are other reputable brands, such as Zilla and Alltrax, but 60v seems 
to be kind of in a "no man's land" these days.  Kelley controllers are 
cheap, but I've seen mixed reviews of them.  

Maybe others here will have further controller suggestions.  

Please let us know how it goes. We're pulling for you and your uncle!

The EV-1 is pretty efficient; notice that it has no fans or heatsinks. There is 
also a "bypass" mode where it closes a contactor so it's simply straight through 
to the battery (100% efficient).


The hangup is that the EV-1 has no input filter capacitors; so nothing prevents 
the battery from seeing its pulsing on/off current. This didn't matter with huge 
industrial batteries. But it's hard on small batteries, whose Peukert exponent 
means that their amphour capacity is less when drawing (say) a 0a - 200a 
pulsating current instead of 100a continuous current.


Modern controllers use a big bank of electrolytic filter capacitors on their 
input. They also run at 15 KHz or more, which reduces the size of the capacitors 
needed. The EV-1 runs at more like 1.5 KHz, so it would need 10 times more 
capacitance to accomplish this filtering.

Re: [EVDL] 85 Year Old Uncle Worked 30+ Years on EV, Needs Help

2017-10-20 Thread Cor van de Water via EV 
Paul,
The controller may be perfectly fine.
If there is no voltage on points L3, L5 and L7 *in reference to traction 
battery negative* then fuse 3 (15 amps) is blown or a mis-wiring has happened,
because only fuse 3 and the key switch are between L3 and battery positive.
This discussion list is actually hosting a library with EV component manuals.
The list of controller manuals can be found here:
http://www.evdl.org/lib/index.html#cont
For the description that you gave, I looked at page 3 of:
http://www.evdl.org/docs/ev1_op_maint.pdf
but there are many more documents of the EV-1 controller available as well.
Let us know if you need more help.
Cor.
