Instant Start 18 fet Infineon Boards are here...

[methods]

by setting the block time to a large value you can go over the amp limmit for a short time.

What?

Oh crap, that is what "Block time" does ?!?!
That explains everything.

This is why Doc was able to burst 170A with only a ~600uOhm shunt.
Now it all makes sense.
His block time was probably set a higher value than mine. (which I set to 1)

As soon as I get home I am going to start experimenting with larger block times.
I really like the feeling of burst current. Nothing like shooting 150A @ 100V through your butt (if only for a moment)

Thanks for bringing that up. Dont know how I never knew that... I thought I had read everything.

I looked for info on block time a while ago but couldn't find anything, I even asked the question but no-one seemed to know at that time.

Hi
sorry my fault keywin told me I never got to post it I wanted to prouve it first.

Geoff

 

[Mike1]

So what exactly does it do and what settings are appropriate?

 

[geoff57]

hi
for those of us who will be using a older pclink the new boards don't have markings on them as to what order the link pins go, so i took my new pclink to bits took some closeups and followed the wires to the board below is a pinout on the board looking from the component side, as with the previous boards Tx and Rx refer to Tx and Rx on the link NOT on the board. normally you attach tx of a pclink to rx of a controller board but in this case the board has been marked to corispond with the link connections.
the pic is taken from a 12 fet board but the 18 fet is almost identicalin this area so i dont think it matters.

Geoff

Mike I am going to do a bit more research and testing and let everyone know some of keywins traslations are not always correct.

 

[Mike1]

I notice the regen now has a max voltage of 75V. Can we still tune this up a bit by changing R12 and adjusting the LVC to match like we did on the old soft start boards? At 72V I need regen up to about 90V.

 

[geoff57]

hi
I have never known anyone that does use it but the ebs+ pad is disabled on both 12 and 18 fet boards it requires Q6 to work and it is missing. on earlyer versions Q6 was surface mounted now it is a solder in component, that has not been put in.
I have never used it nore have I ever had to do anything but remove it so for me this is fine, but for anyone putting one in a motorbike with rear brake lightson 12v which is the intended of EBS+ Q6 will have to be replaced.

Geoff

 

[Mike1]

I actually use the 12V brake signal so would need to add Q6. Do we know what transistor this should be?

hi
I will have to get in touch with keywin on that the smt transistors on earlyer models dont have a code for me to check.

Hey Everyone,

I just want to let you know i was succesful at flashing my board today.. I had the program on my computer .. but i wasn't using the mod that methods posted earlier about hiting the transfer button then connecting the ground on the usb!

Since i feel like the least experienced on these 18 mofet boards .. I was wondering if anyone could outline how to get regen at a higher voltage then 75.. I'm presently using 24s 10p of a123 batteries .. which fresh of the charger are 88.8v .. anyone please direct me where i could find some more info on the subject!

Glad to hear you got it programmed.

So then you must have plugged in the USB, pressed transfer, and then plugged the header into the board right?
That would basically be the same thing as toggling the ground... Only it cant be done while the case is on.
The way the micro controller works is that it will only allow programming right after power up so something must be done to toggle power.

I dont think you are saying that you soldered in the header, plugged in the USB, pressed transfer and it worked. That's not possible.
The purpose of my mod is to allow you to solder in the header and program the controller after the case is on.
An alternate to my mod would be to solder in the connector and then add a second connector that could be broken/reconnected outside the case to transfer.

No matter what power must be toggled to transfer data.

@ Steveo and Mike1

For regen at a higher voltage then 75 you need to make the LVC mod on R12. I have lowered R12 from 1.2K to 960R. This means the real voltage is the programmed voltage +25%. So 75V max regen voltage is now 94V.
See the last lines on my post and the right upper corner of the schematic: http://endless-sphere.com/forums/viewtopic.php?f=2&t=10312&start=315#p169765

I use EBS+ too. You need just added a NPN transistor (Q6) and then it works fine. I used a SC2240 I had in my stock. But on this one I had to adapt the pining.

hi
thanks sam saves me trying to find out that one

For regen with 24s lithium check first at the 75v setting there can be some leaway in the values, on the first 12 fet infineons they said no regen over 48v but a 16s LiFe A123 worked fine and that is nearly 60V fresh off the charger. 100 volters will need a regen mod no question but at 24s we might be able to get away with it.

[Mike1]

Thanks Sam-Pilot, that helps a lot.

Just confused by one thing. On your previous post it shows R12 being 1K not 1K2 like it was on the old boards. Wouldn't this make the 960 ohm value wrong? :?

Mike.

hi just looked at a 12 and 18 fet board both still have R12 as standard 1K2.

urgent help required
has anyone got the driver for the USB to PC link for Windows XP.
this is the same link that methods modified in a post before and steveo uses one as well I belive as he made the same mod.
I found the software for my vista PC but it will not run on my XP PC neither will my friend's on his XP PC.

Maybe it is time to start saying "Instant Start 18 fet 116 Boards are here..."


I think Keywin and Xie-Chang are no longer selling the Infineon chip boards.
Apparently the "116" boards come in 6, 9, 12, 15 and 18 mosfet "flavors".

The standard R12 value is 1200 ohm. Lowering the R12 value will increase the (programmed) regen voltage limit and also increase the (programmed) LVC.


EXAMPLE:
SAM-Pilot changed R12 to 960 ohm.
So if the regen voltage was programmed to 75V it is now actually 75 x (1200/960) = 93.75 V
AND if the LVC was programmed to 21V it is now actually 21 x (1200/960) = 26.25 V

Gotta Love the name of this application ...



Download the exe file here ... http://98.131.176.65/endless-sphere/Parameter_Designer_For_116.exe

You may need to add some COM PORT files for your particular PC OS (Richtx32.ocx & MSCOMM32.OCX).
These are here also (right click "Save Target As...") http://98.131.176.65/endless-sphere/Richtx32.ocx & http://98.131.176.65/endless-sphere/MSCOMM32.OCX
These need to be copied into the C:\WINDOWS\system32 directory for the Parameter Designer.exe to work properly.

Hi Geoff,

I was looking at the wrong resistor I think. I was looking at the one labelled RS12 on page 22 of this thread.

I made my own pclink cable so don't know if my drivers will be compatible with your cable. I'll PM you the driver I use anyway.

Mike.

Knuckles:

Does the new "Keywin Lab" app support the older true Infineon controllers (e.g. EB812XC-A-B board)?

PS - great to have you back...h

 

[steveo]

So I had a chance to test the software out.
Here is a screen shot after a successful burn:

Unfortunatly I cant upload a *.ASV file

Create a file named XXXX.asv
Past this inside:

5:EB218
70
30.0
20.1
1.0
99
0:Switch Mode
100
80
60
1.0
15.0
1:Only Fake Indicate
1:Comm GND
2:
35
75
0:Low
0:NO
0:Fast
0:Cruising Indicate
0:120 Degree


For those who have already had the old software installed you can just run the EXE that Geoff posted.
All I did was run the EXE, choose all my parameters, then save them.
The saved result is what you see above.

I came up with those values by first using common sense, then looking over the values used on the old software, then analysing the choices in the new software.
This is at least a reasonable place to start.

If in doubt set all speeds to 100%.

Remember that the current is a relative value, not an absolute value. If you double it from 30 to 60 you will get double the current. This all depends on your shunt value. They REALLY should have a field to enter your shunt value :wink:

Hey Methods

I tried the setting specified in your provious post .. but i have shitty acceleration .. I'm estimating 30-40amps draw on launch .. i didn't measure exactly.. I am using the factory shunt which i estimate is between 80-100 amps.... could you post another screeny of setting that work good or perfectly for you with the factory shunt!

NO. The "116" is a different chip. This is all new territory.

For Infineon use the older software version here ... http://endless-sphere.com/forums/viewtopic.php?f=16&t=7361#p110931

PS I never really "left". I just needed an "ES" vacation!

-steveo

Actually, you are seeing just what you should be seeing, so good job!

The factory shunt will give you apx. 30A continuous acceleration.
If you want to get up near 100A cont. you must solder the shunt down to 250uOhms
If you lay two pieces of solder wick on top of the shunt and then drench the entire thing in solder you should get close.

The shunts that Keywin put in are NOT matched to the software. The software expects about half that impedance. Setting the software to the max current (60ish amps?) will net 30 - 40A continuous.

I am currently looking for a better shunt solution. Will probably end up being (4) 1mOhm shunts in parallel. This should better handle the heat and it is very hard to find a single, high power 250uOhm shunt.

Maybe SAM-Pilot can guide us toward the best way to re-scale the current sense circuit.
We dont want to rescale it too far since the shunt cant handle the heat....

Power at 100A for various shunt values:

250uOhm shunt
100 * 100 * 0.00025 = 2.5W

500uOhm shunt
100 * 100 * 0.0005 = 5W

1mOhm shunt
100 * 100 * 0.001 = 10W

So... It may not even be wise to spoof the circuit.
To me it looks like the best option is to lower the shunt value to 250u.
You will lose some resolution but it wont affect the controller performance negatively.
The CA actually has a very good input resolution so you may not even take a hit on your Ah readings.

I agree. I am not going to change the name of the thread but I think we should definitely start referring to these as the "18 fet ______ boards" at a minimum.
Perhaps someone can come up with a clever Xie reference.

I guess we could suffix with the 116 but it is so un-descriptive if someone does not know that it refers to the chip part number.
On the other hand, when the chips change again the 116 would help differentiate software versions.
