12 fet is good up to 6kw. Bullshit...if you cant multiple amps with voltage dont spread wrong facts!
the 12fet can do 10Kw all day long. On heavier EV phase amps may not be enough to last the smile on your face. thats all.
The Sur-Ron controller isn't horrific so the Nucular won't really improve efficiency, just give you more phase amps to play with. And that might actually lower efficiency if you try to run more amps into the motor than actually do any good.
Do you have a Surron? Do you have the Original Controller? Do you know how much the Motor can eat?
No ?....so stop talking diarrhea again.
The Motor handles even the 24f well. The Stock Controllers regen is a joke. Regen is not for efficiency on lightweight EVs. Its more saving your MTB Brakepads. If you ride above bicycle speed, wind resistance eats all your efficiency in no time.....
Variable Regen is the best way to slow down your EV.
Push Button sucks, Auto-Regen sucks too.
A battery pack is a source of current and voltage. So yes...the Nucular will use any battery pack. What I don't know is if the Sur-Ron BMS is tied into the the Sur-Ron controller in any way. Will the BMS allow you to use the battery pack if it can't talk to the controller? I might consider getting another BMS that works independently. There are quite a lot of good ones out there that are smart and not very expensive.
thats the point....your suggestions and knowledge is far away from real world. Stay on your disassamble crap. Open controllers for pics and stop talking about stuff you have no clue.
You dont even rode a nucular controller until now....
Iam so tired of you.
Hey buddy...stop attacking me. I didn't attack anybody including you and I rarely ever do. Deal with facts instead of attacking my character. It shows low character to attack a person instead of dealing with the facts. It shows an inability to deal with ideas and so the common reaction is to attach the persons character. Please stop attacking me and stick to the facts! I'm not an idiot and neither are you!
I got 2 12 fets and a 6 fet just as soon as Nucular would let me buy them. Same for the 24 fet. What exactly are you talking about that until now I've never rode a Nucular? I've had these controllers just as fast as Vasilli would sell them to me! I think you should hold back on those unfounded opinions.
Specs say "Maximum power 10 000W (80V+), Nominal power 5 000W (80V+)"
That sure doesn't read like "10kw all day long".
I only said 6kw becasue I PM'd Vasilli about real world continuous rating several months ago. 5kw is conservative and 6kw continuous is doable.
I've already been thinking about how to make a 12 fet do more continuous wattage. The real hurdle is heat and the TO-220 leg limit of 75 amps.
The Sur-Ron controller isn't an epic pile of steaming doggy doo doo. It's flat out NOT! Is it the best thing there is...well obviously no. But a complete failure of a controller is flat wrong. That's simply NOT the case!
Will a Nucular controller be an incredible improvement? It will be better, but it won't cause the sun to go super nova or even change the world. It's an incremental improvement.
Motors and magnets...everybody knows this...it's pretty obvious. Magnets generate only so much attraction of repulsion. The stator windings can be powered beyond the strength of the magnets. At that point more current in the stator windings does NOT create more torque. You can test this easily. Set your Nucular controller to max phase amps on a motor that can't handle it. What happens? The motor gets hot and doesn't produce more torque. Set the phase amps to whatever is the maximum that motor can handle without getting overly hot and maximizes torque. More phase amps beyond that is pointless...you've reached the limits of the magnets ability to attract or repel. Who cares what motor it is! It's still true. I don't need to own a Sur-Ron to know this!
I do agree with you about variable regen...it's the best way to implement regen. Folks that are technical understand this (you and me). End users that just want a bike with regen don't. That's usually the folks that buy an already complete EV like a Sur-Ron or anything else.
I have no comment about your attack on my comments about Sur-Ron battery packs. What was the point you were making? I did say I didn't know if the Sur-Ron BMS talks to the controller and I did talk about the implications if that was the case. Maybe someone urinated in your wheeties this morning and I'm the vent for your rage? I don't know, but what I posted is sound and what I would do to get away from a proprietary solution.
Is the Nucular controller pretty darn good? Absolutely! I don't have 6 of them...the entire product line... because i think they are shit.
Is there room for improvement? Yes!
Areas where Nucular controllers could improve:
There is no opto isolation between the mosfet drivers and the MCU that I see.
There is no phase current checking. It's all based on the batt- shunts and a calculation. Shunts or current sensors on each phase is best.
The soldering of the mosfets is not great. I've posted on this previously.
No BT functionality.
Good aspects of the Nucular controllers:
Pretty beefy phase and battery busses.
Large phase and battery wires.
Use of firmware that can be updated...this is BIG.
An LCD that programs the controller and also makes for a nice dashboard.
Open source...I LOVE open source!!! I have access to the github repos and sync them locally fairly often. I LOVE open source!!!
Compact, attention to details and yet no lack of performance.
Loads of features that lots of more expensive controllers lack.
Regular firmware updates!
Vasilli/Nucular: Thank you for making pretty darn good controllers. I'm generally very pleased with your work!
