72V 40A Sensorless controllers $100 (SALE OVER)

[methods]

I am hurting for cash - I need to order parts & PCB's for my run of HVC Breaker Boards.

These are 72V Crystalyte Sensorless controllers with the real CA connector (not the fake one)
LVC is at 55V so these are perfect for 18S Lipo (my current favorite pack)

Here is a brief description on my website: http://www.methtek.com/2011/11/12/72v-sensorless-30/

$100 each
That is below (way below) what I paid for them but I have 12 on the shelf and they are not making me any money right now. I need to put together $1k so I can do a run of these boards.

Shipping will be $10 to the US and $22 to Canada

Can they be toned down to 20a and have regen enabled?

I imagine regen is going to be tricky running sensorless...

? sensorless controllers don't have regen ?

How much for shipping to France ?
thanks

Ordered one and a CA from the online store! Thanks!!

You can use your CA to set the current limit anywhere you like. As far as regen - I cant say for 100% certain but I *think* I tried it some time back and did not get any. That does not mean it cant be done - just means that in my half-ass test it did not happen So dont count on regen.

$33 shipping to France.
Lets say:

$10 to the US
$22 to Canada
$33 anywhere else

To keep it simple.
FYI guys - here is a great tool: http://postcalc.usps.gov/
Just enter your Country, select "package", and enter your weight to get the full list of USPS (best pricing) shipping out of the US. In this case we are looking at a 3lb package.

I can provide any shipping option you see on that page that has an "internet price" (i.e. no first class mail)

Ar they the 12 FET ones? Board possibly marked EB312-C-1?
Do you know if they can be programmed?

[SamTexas]

Is it 72V nominal (19s Lipo) or 72V max (17s)?

[NeilP]

I just had to fix an Xlyte 72 volt 40 amp sensorless controller from Electric rider, a 12 FET unit with FB4310 Mosfets

the data sheet shows them good for 100volts, and the caps are 100volt also

i have run it at 98volt quite happily for a few miles, so assuming this is the same controller then it will be good for up to 24s LiPo

IF I had a CA... I dont.
Are they PURE sensorless or do they have the halls?
Ive used a few sensorless controllers and the ones I bought did have regen..

Are these programable at all?

[methods]

You should buy a CA

Yes, they are pure sensorless.
I don't know if they are programmable. Assume not.

These come from the same source as the Electric Rider model (Kenny at Crystalyte) but these may have been spec'ed out a little different. They do have 100V Caps and 12 x 100V FB4310 fets. The boards will certainly run to 100V - the only real limiting factor is the firmware setting of a 55V LVC. The upper limit is driven by the cap voltage, fet voltage, and power developed over the power resistors (so they may run a little hot...).

To lower LVC you would need to increase the value of R12

If anyone knows more about these than me please feel free to chime in. One thing I will note is that many of this type of controller (like the one sold by Electric Rider) are configured to mate to Kenny's CA knock-off which interacts with the uC in real time. Anything that black box can do you should be able to do - so that probably means changing LVC and current limits. I am totally out of the loop though - I am sure someone has a thread going somewhere on how to talk to these new Infineon chips in real time (i.e. someone has reverse engineered Kenny's box). If no one has - they should

P.S. I am getting close to the $1k I need to place the order - thanks to those who showed up right away to support me - I appreciate it! This sale will probably end this weekend.

Hi

Would your controller work with my bike

http://www.motorino.ca/motorinoxpn.php

to bump up to 72 volt lipo ?So I can dump my sla bricks.

Thanks

PS-are the hvc boards that you have designed going to be used to check the voltage from a charger so i wont have to buy a bms and use my CA as a lvc?

If yes to both questions,i think my dealer will buy some too.

Cheers

This controller will work for a voltage range between 55V and 100V. You need to evaluate the LVC and HVC of your specific pack to determine if this is the case. 18S of lipo has a 54V LVC so that is the minimum lithium voltage you can use. The maximum would be 24S -> (unverified) so if you want to be safe I think you are looking at anything from 18S to 22S.

It is a little more complicated than that... My boards monitor each individual cell (or parallel group of cells) in a pack to detect if any cell goes below LVC or over HVC (two conditions that cause damage). If any one cell drops below LVC (3.0V per cell) it will clamp the throttle voltage to 0V and inhibit further discharge. That is the behavior of the HVC/LVC/Parallel boads. This latest board is an add-on circuit breaker that will terminate charge if any cell goes over 4.29V. It is basically a mosfet circuit that clamps to the OFF position if it gets a signal from my HVC/LVC/Parallel boards.

So this is higher end cell level protection (not just Pack level protection like 90% of folks do). With a system like this you are assured that even in the case of extreme imbalance you can not damage any cell or group of cells by over discharge or over charge. It is also now nearly impossible to have a lipo fire. Total protection.

BUT -> This does not balance your cells - so you very well might need a BMS to do that -> and any *good* BMS should also provide cell level HVC and LVC protection (though many do not).

If your dealer wants to talk about Battery Management have him/her contact me at MethodsTechnology@gmail.com

Thanks to everyone who helped me put together the cash for this HVC build.
This sale is now over.

I will honor the sale price for anyone who has a PM in the queue already.
(or of course anyone who had a sale in progress)

I have got one of these Electric rider controllers.. Methods can you check the board type? I think EB312-C-1

If yours are the same, then programming with either XPD, Keywin, Lyens or Cell_mans software does not seem to work...although the Xlyte "CA" (..the APM.. ) does allow changing the settings. (LVC/HVC current limits etc)

I have tried with with two versions of XPD, and about 4 different versions of the Keywin/Lyen software..and no dice.

Best I have had is XPD giving an error....now, brain fade here ..but the error was something like :

Incorrect Controller response received byte 78...

Sorry i know that is wrong...but can't remember what it was... But anyway..it seems that the TX/RX to/From the controller/PC was working...but protocols were wrong.

i can possibly borrow an APM , and if someone gives me help, I could try and capture the data output from it, when it send commands to the MCU...but on my own I do not know where to start
