Re: [EVDL] Hyper 9 low-end performance problem

[Rick Beebe via EV]

Dan was helpful enough to send me his clone file (it's the controller 
configuration). I compared it page-by-page and only found one 
significance difference. There's a "vehicle information" section that 
has end gear ratio and tire size. In mine the gear ratio was 7:09 and 
tire size 589mm. On Dan's, because he's driving a propeller, it was 1 
and 100mm. So I set mine to those numbers and my low-end performance 
improved dramatically. It still struggles going up my driveway but now I 
feel it's a gearing problem and not a limited current problem. Also, it 
can now back up the driveway. No idea if that change impacts anything 
else, though.


So thank you very much Dan!

My next step will be to swap out the 3.73 gears in the diff for 4.10. I 
think that will give me better low-end torque without limiting my 
top-end very much. As it is, right now, I'm software limiting it to 
about 80mph. 70 will do me fine.

Hey Rick
I have a hyper-9 on my 20' pontoon boat and it certainly delivers full

it is their stock HV 144v controller that can with it.  I'm running it also
at 160v nominal from a split chevy volt pack.  I have a whole other hyper9
HV kit going in an MGA, interesting to see how it works in a car and hoping
I don't have issues as you describe.
I know the software that comes to setup the hyper9 has quite a few options
so I could try and capture some screens if needed.

One thing to realize is that the DC motor would happily take full power 
from the controller, and give you WAY over spec torque at the low end.

For the most part I'm very happy with everything, especially since my 
power consumption has gone from about 2.7 to 3.6 miles/kWh but it 
feels to me like I have a problem at the low end. In normal driving 
the truck accelerates like my old '64 Beetle used to. That's okay but 
it's a real problem going up a hill. My driveway is rather steep and 
the truck can only manage about 10mph going up the hill. If I stop on 
the hill it won't move at all. Nor will it back up the driveway.

Thanks. I should have added that the Hyper 9 has its own controller. The 
Raptor is gone now.

For the most part I'm very happy with everything, especially since my power 
consumption has gone from about 2.7 to 3.6 miles/kWh but it feels to me like I 
have a problem at the low end. In normal driving the truck accelerates like my 
old '64 Beetle used to. That's okay but it's a real problem going up a hill. My 
driveway is rather steep and the truck can only manage about 10mph going up the 
hill. If I stop on the hill it won't move at all. Nor will it back up the 
driveway.

According to the torque charts from Netgain compared to the ones from ADC, the 
motor should be plenty strong. I drove almost all the time in 2nd gear which 
was 2:1 and the TorqueTrends is set to 1.9:1 so there's a little penalty there. 
I am thinking about changing the rear end from 3.73:1 to 4.11:1 which will help 
get the gearing back.

But it feels to me like the issue is that the controller is SLOWLY ramping up 
the current when I step on the accelerator. When I turn in the driveway I can 
put the pedal to the floor and the battery amps don't climb above 100 until I'm 
nearly at the top--about 6 seconds later. If I'm driving at 20mph and stomp on 
it, the amps will zoom right up to 400 and the truck accelerates nicely.

Does anyone know of a setting in the controller that can tweak the current ramp 
up speed? The current limit page shows 100% across the entire RPM range, so it 
has to be somewhere else. The throttle page shows that I'm getting full pedal 
travel. I'm not looking for burnouts but I'm dreading the day I have to stop on 
a steep hill on a real street. Thanks for any help.
