Q100/EB306 Current Settings

[Marctwo]

Oh no!!! Sorry to hear that Dave, I'm feeling for you...

I like the idea of doing the hall wires instead of the motor wires, though. Mine seems to be running as well as I'd expect but it'd be simpler when reconnecting the controller instead of having to remember the magic combination.

Its one reason I prefer a sensor-less setup even if there some slight disadvantages.

Update .. good news is that it appears to be talking to the Lyen mark2 controller program, not sure if thats the right one to use... but hey, it cant get any worse

 

[NRG]

Your phase current is far too high for a standard e-crazyman controller or is that just a screen grab from somewhere else? Rule of thumb is 2~2.5x the battery current so 35 or so with the above.

 

[Old_Dave]

It was just a quick test to see if it would talk to me..

I'll do some sensible settings if the repair goes ok

Don't know if you know but you can't pull settings from a controller, you can only load settings to a controller.

 

[Old_Dave]

Yep.. I knew that

Is there any default 'stock' settings ?

OK understood O_D.....I've got the default 7/15amp 250w settings somewhere, I'll dig them out...

When programming be mindful that the battery current control is not very accurate it can be +5amps over, so a 15amp setting works out at 20amps and given the multiplication factor, say, from your screen shot above (3.6) your phase could hit 72amps...which would blow the standard FETs and probably many good ones as well as the heatsinking is not that stellar...

MOSFET now removed



New one and 7 spares on the way.... At the cheap as chips price of £3.82

Nice one, Dave... Let's hope you don't need the spares any time soon.

I've been using mine @15a for the past week and it seems pretty good so far. It holds a comfortable 22-23mph on the flat with peddalling but seems a bit slow when it drops to 16mph up hill... How they ever came up with a 15mph speed limit is beyond me???

Lol

I hope that as well..

The good news is that in the event of anyone else doing the naked wires juggling trick and suffering the same accident, then I'll have a spare for them.

P.S its the wires that were naked not me.

It was decided on by people who haven't been anywhere near a normal bike, let alone an ebike

 

[Old_Dave]

The mosfets arrived today... They came much quicker than I expected

Update..

Fitted mosfet, fitted controller on to bike and bang.. another mosfet killed it self, replaced 2nd mosfet and zilch, nothing.. dead as a Norwegian blue

Ordered a new controller / swapped plugs and worked out colors for halls and phases... funny thing is that this time the best was different (maybe I hadn't found the best'ist best before it went bang)

Halls & Phases
B - B
Y - G
G - Y

Now using xpd rather than Lyens software as xpd is better, lol

Done a few road tests with various settings... all I can say at this stage is that 120% is interesting, if only I was about 6 stone lighter it would go like a rocket

 

[amigafan2003]

My Q100 show the same no load speed at 110% and 120% - try it and see what you get.

 

[Old_Dave]

I didn't note any no load difference between 100 & 110, but 120 was quite a jump, will connect the laptop and test again..... This time I'll write the results down, lol

You might find this info useful OD....

[Old_Dave]

Ooooops, my bad, armed this time with pen and paper, the no load speeds are
100% = 26 mph
110 and 120% = 33.1

Interesting...

My no load speed at 100% is 45mph so in theory it could be more like 57mph at 110%. I wonder how that'll affect my real world speed...

In the real world.... Not a lot, lol

There are at least 10000000 reasons why, air resistance as speed increases being the main one, a stream lined and enclosed bike ridden by a 5 stone rider with a tail wind however would see a good gain at those speeds.
