The question remains, what is innovative about bucking 48 VDC to 12 and 5?

thats 1/12th of the requirements i mentioned.. forgot to mention the compressor would not kick over on inverter power alone either. it had to be plugged in or running on the tesla generator. So now also add the dc power requirements back in line with the other dozen or so, add 8 month as the two engineering teams could not meet all those requirements with in the available voltage being carried on board, and it all gets wrapped up with 300.00 with surplus parts and pizza and a 15 min drawing. not only did it all work i was able to maximise unit efficiency to 12 hours.

and not to mention this is the first time any of this has been done in this application or field. You ever watch Apollo 13 with tom hanks? remember after the command module explosion they shut everything down to save power for the landing? lieutenant dan was spending days in the mock up on the ground trying to power up all the critical systems needed for their landing, but was working on a very tight power budget? and if he powered things up wrong or if he used too much they would not be able to land? same thing but instead of saving astronauts i was helping the company win their part of a 8 million dollar obama era grant for developing electric vehicles.  

that... is how it was innovative, which again is not the name or what i called this project. it is part of the name of the company i created after i was compensated and left the Italian refrigeration company..

wasa matter you no speaky englishie? my "friend"? you mean the one who has my youtube page? the one that has been posting technical videos since 2010? the one that shows a walk through of my shop? the one that shows the equipment that ended this argument? the one that has a couple dozen bible study videos in said youtube account... the one who uses my name and sunflower avatar? that friend? simple atheist that not my friend, it's me

Ok, sure.

To be fair, I don’t doubt in the least that the Drich on YouTube is the same person as our Drich.

Just because it's in a video, doesn't mean drickhead isn't being lead.

I don't think for an instant drickhead is even slightly truthful.

Now, you're getting fuzzy again.  Not interested in movie analogies or company names or mistakes by the project engineers.  What you're describing is a clusterfuck of a project.

So, a soft start for the compressor so that inrush current comes from the generator but switches to the inverter once running.  That's a couple relays.  One being a delay on make.

Two buck converters for control voltage.

A battery monitor.  That's a dial or analog input to the controller.

BTW, what was the controller?  PLC or an OEM board?

The power demands of the refrigeration system are fixed by the setpoint.  The charge time for the batteries are set by the battery type (how much current can they take ) and the current available from the generator.  The charge life of the battery is set by their AH.  How did you program the controller to maximize system run time?

What else?

that's because you are a stupid person who ignores facts in favor of narrative... which you don't seem to be aware that was the whole reason/lesson in this thread. In that most of you are guilty of formulating a biased thought/position about a person or topic, and proceed to ignore fact, in favor of your narrative. i proved this over and over and over again even with the examples you gave. and in your best effort to refute this, you double down in your ignorance. But that is not what makes you stupid. that means you have little to no self awareness. this is why you are still running your mouth after everything is over. you are too... "unaware" to know it's over.. which is why you are pushing another baseless narrative, and still refuse to look at the facts. what makes you stupid in the content of your new uninformed narrative.

because even if i were a team of people... "we" collectively are still kicking your ass. So that means there are no stupid people here... whether it be me or a team the net result is you ass kicked. metaphorically of course. What makes this a narrative is it ignores all the facts and consistency of me being here almost 10 years, and still retaining the alot of the same flaws the 'good people' of this web site have pointed out over and over and over again for almost a decade.

that is why you are stupid. 

after all this, you still ignore fact to propagate a narrative of your own making!

I retract my earlier statement about Drich potentially being a thief. Your linked quotations are clearly not something written by Drich himself, but copy/pasta from somebody else's Jesus fantasy from facebook. It is too grammatically correct, well spelt and coherent to be anything from his brain.

My apologies.

Again you fucking asshat, just because you post something saying you did it, doesn't make it so.

Just like your stupid highway to heaven story.

You are an idiot. Anything you post, that has even a whisper of intelligence to it, someone helped you with it.

here is where you messing up again. the devil is in the detais. the reason i gave you the movie anaology is so you could understand the vital need to sequence and modulate amp draw. all the bs you laid out was similar to what the two engineering teams laid out.. while a soft start would control motor run up it can't help with amp consumption. which is a very big part of running a 15hp compressor on 48vdc batteries only. plus when plugged in the batteries need access to a full charge rate while the unit is running. (gotta keep product cold, and we only have the one power plug @ 25amps.) so pitch the soft start because remember the truck is not plugged into anything generator or line voltage. it only has battery when operating over the road. and it will not help modulate demand while being charged.

also buck the converters (we don't need them with my design and we are also on a tight budget.) Which i came in under.

the control board was an oem i had modified to my spec. ( i also set the parameters and limits for high speed cool, low speed cool, defrost, high and low speed heat./charging cool, defrost and heat.) this is the part that took the longest.. they orginally had two thermostats one that controlled it in cool the other in heat.

as far as the power demand being set by the set point.. wrong again. i used a VFD different types of fans and refrigerant to set the power demands. the vfd allowed me control voltage frequency to the compressor i could change the voltage and the Hz. if i remember the vfd also had a soft start ramp up built into it. that took care of the start on battery issue, then we used it to also control compressor speed and amp consumption by reducing the frequency of power the compressor was being fed. this allow for full charge rate at batteries and for the unit to maintain temp in 'low speed'. once the compressor was running. I think dont hold me too it but i think we could run about 75% of max speed and still progressively cool the refrigerated box about a degree a min. which in plug in mode (at night) is not bad. Then we optimized the system. this drastically changed power consumption by changing the refrigerant, fans and a few other things and dropping the head pressure from 325/350 psig to 150/175psig. this went from 15to 18 amps down to 6 to 8 amps.

oh and your 'fuel gauge' only tells what the surface charge is in the battery not how long you have left. plus it's on all the time.

plus phase selection.. that can be accomplished by buying a 2000.00 phase selector, but it put us over budget, would literally add twice the heavy wire in the box, and would make the whole system sensitive to moisture. so there is a way i fixed that.

then the whole unit had to be rewired as it was wired to accept generator inputs.

reduction in head pressure means the compressor needs less force to build up to double the new working pressure.

that is the what i did. don't ask how. nda/non compete 

Again, there is no generator.

READ THE STORY

The generator truck worked with conventional diesel trucks.. trucks with transmissions and diesel engines.

i was working on one of the very first all electric trucks, so they wanted an all electric refrigeration system

the closest thing on the market was this generator truck system. problem was no way to run the generator. (electric truck don't have transmissions like the diesel trucks.)

purposed solution was to run the truck on battery power for no more money than the cost of removing the generator out of the cost of the existing system. plus we could not add more than 1000 pounds to the whole truck.

so limited weight. limited funds and without the parts they want to take off the unit will no longer run.

plus originally they wanted to use all of the old parts that made the generator truck work. my purposed list redesigned everything but was much cheaper meaning we could add weight and batteries.
