I know how this works.
I can tell you absolutely, I think.,. Tractive effort ( curve ) load, battery ability, RPM rang and kV, all have an effect. Time, current demand, whats what... On how Kelly lays out the power.
For instance: Here is a KEB72801X: 2018 controller.
8Kw rated by Kelly. 350A peak, 165A continuous is the datasheet.
I pulled 280 amps out of the battery.. 18kW battery horsepower.
Explain that "its phase amps" people. Well.. It is.. The waay phase amps and battery amps interact with load and speed... for one thing.. but.. With a good homemade pack. I also ran this bike on a Top of the line hobbyking Lipo.. and it was much much 3worse. 1/2 the power was al the lipo could hack... Lipo complied and that was that.
I just sold a 459$ Kelly for 180$ and it was a " 450A " controller .. with a 160A continuous.. Rated 12kW by kelly.. a heavy golf catr type controller.. It was listed as " 450A for 10 sec, 400A for 30 sec, and 160 A contin." A very large controller (massive).
Basically the controllers peak at start ( when maximum tractive effort is neccesaryon a traction system, prime mover) and igf you have it setup rihgt it will haul inthe RPM rangeyou need..
Lufgging and loping do not do well, the 10 sec is up,revert to controller max rating.. contin...
.....here is another log. KEB 72330
: Somewhere from 2012-2013.. I think. At least before 2015.
It is a 3.3kW rated controllr.
I pulled 7980w and 107.2A out of it. I heat this one up.. I have ALL the tractive effort with this level of power and do pull full controller phase amps.. and battery amps from that.
BIG BUT.. It tries 100a, 8kW... BUT.. after 30 seconds it REVERTS to a current throttled state where it will only put out the ( half) amps of the rating.. So I cruis alot at 40-50A contin ( max contin,.. ) but if I can peak here or there.. it WILL.... given how speed and phase amps are related.. It is a 3.3kW controller and puts out 3500w continious.. but PEAKS when IT CAN.
I could ony pull 280A on the 350A controller. Then the tractive effort dropps, back EMC is up, current drops, blah blah blah.. That was it.
....peaks. Off the line. In the first 10 sec. After 30 sec they revert to the lower rating ( that is quite often half the phase amp rating and yes, Kelly does call it the phase amp rating).
Alot matters from the consumer point of view and the rating and how they work is kinda muddled. PersonA ays this: Person B says this.
I will link Kelly Controllers description of the ratings and current applications. How the numbers work. This is how it does it.
Here is one of the million Indian/Pakistani/Middle Eastern/ Far Eastern Engineers describing ( how to fundamentally model and diagram) Tractive Effort. In ye goode ol (broken) British English.

Here is another in good ol American English. By some kid who looks to be a 17 year old enginoor. Lol. Description is great. Lil ol engineering kid with 3.2 million subs. Lol.
