Hey all,
So... I FINALLY (after about 8-10 months) finished my new ebike build... just need to figure out all the settings because as of right now, I am able to get to ~67mph but the acceleration is like... crazy slow compared to my last build (that had the same battery as this one).
- Controller: Sabvoton SVMC 96120
- Battery: 86v (~72v min and 97v max). I currently have it limited to 50 amps but can output a max of 80 amps continuous.
- Display: Cycle Analyst 2.3 with 150A 0.5 mOhm shunt (this isn't working correctly for some reason though).
- Throttle: potentiometer type - Magura Twist Grip Throttle 0-5K Ohm.
- Variable Regen throttle: Hall type thumb throttle.
- 3-way speed switch (I honestly can't tell which is high, medium or low. They all seem the same because the acceleration is so slow.
- Brakes: Tektro Dorado e-brakes (disk).
- Headlight: Fisher Fab House Ultra 3200 LED E-Bike Light connected directly to main bike battery.
- ignition: key switch.
- Shunt: 0.5 mOhm external shunt for CA-HC, up to 150A continuous, 400A peak https://www.ebikes.ca/shop/electric-bicycle-parts/ca-accessories/shunts/shunt0-5.html
So really I have two issues I'm dealing with.
#1: acceleration is crazy slow compared to my old build that used the same battery limited to 47 amps. Here are my controller settings:
BASIC:
- Lack volt: 74v
- Over volt: 115v
- dc limit current: 50A
- Rated phase current: 150A
- Max Phase current: 150A
- Protected phase current: 200A
TEMP:
- Unwork temperature: 90
- Rework Temperature: 80
- Limited current temperature: 70
FUNC:
- Electric brake: enable - I have variable regen braking setup but it seems to only be 0 or 100. I thought I once downloaded a special version of the software that had an option for variable braking/regen but now I'm not finding it - anyone have a link to that custom software?
- electric brake ph current: 125A (temporarily set it to that because it was barely doing anything).
- Boost/3 Spd: 3 Speed - though I can't really tell if it's working or not...
- Cruise: disabled
- Reverse speed limit 20% (I don't use this though).
- Flux Weakening: enabled
- Flux weaken current: 30A
- Reginerative charge: disabled
- Slide regenerative charge current: 50A
- Slide regenerative charge speed: 100rpm
THROTTLE:
- Throttle min volt: 1.37
- Throttle max volt: 4.47
- Acceleration time: 200
- Deceleration time: 300
- Throttle mid volt: 2.5v
- Throttle mid current: 0.02A
MOTOR:
- Motor direction: 1
- Motor Pn: 16
- Speed limit mode select: no limit
- Motor limit speed set: 100%
- Low speed set: 45%
- Middle speed set: 75%
DEBUG:
- Current loop kp: 999
- Test given current: 0 - not relevant unless testing.
- Hall angle test: disabled (not relevant unless testing).
- Hall angle: 243
Anything look way off? I just finished this build literally today and test rode it with these settings. Should I bump the amps up to 80A (the battery's max continuous output) or should I keep it lower? And if so, should I set the phase amps to 2.5x-3x that number? What about max phase current or what about "protected phase current"?
Should I change any other settings? Like acceleration or deceleration time? I notice it kinds of "jolts" when I first apply the throttle (kind of makes a click sound).
And then yeah if I can find the custom software that I once found but now apparently lost that allows variable regen... that would be fantastic. I could have sworn I had the correct software on my computer but now I don't see an option for it.
Problem #2: I can't figure out what to set my RShunt value to in my Cycle Analyst... it's currently set to 1.9 but I feel like it's not reading correctly. I've found some information on this and they say to test it but... test it with what? I have a multimeter but I don't think I could ride around with it attached... also where do I even connect it to find that value?
Cycle Analyst settings:
- Set Wheel: 2155 mm
- Speed limit: 95mph (throttle is not attached though as I don't need to control throttle through Cycle Analyst).
- Amps limit: 97A (throttle is not connected to CA so it doesn't matter).
- Low Volts Limit: 74v (again, shouldn't be relevant due to no throttle attached to CA).
- Main Display: Watts
- Set Range: Low (0.01A)
- Averaging: 5
- Set RShunt: 1.9 mOhm (this is where I really don't know what value to set it to).
- Zero Amps: N/A (blank)
- Volt Sense: 31.27 v/v
- Set #Poles: 16
- PSGain: 0.08 V/mph
- IntSGain: 200
- IntAGain: 300
- IntVGain: 800
- ITerm Max: 3.79v
- ITerm Min: 0.49v
- Max Throttle: 4.98v
- Set Ratio: 0.0993 LG/HG
- Serial Output: 1 Hz
- Aux Voltage: Off
- Aux Thresh: 0.99v
- VShutDown: 10v
This CA 2.3 is from my old bike that was built by someone else so some of these settings may need to change but... not sure which ones. Even after reading through the manual.
I know this is a lot to read but... any help would be GREATLY appreciated. I've read through (I believe) all of the Sabvoton instructions and am still kind of lost on what I should set some of these settings to.
