The following post, including images and video have been submitted by Maico Marzocchi.
I think it is very stimulating for those who follow Dr. Rossi to have an eye for what happened “before a demonstration”.
Very often, precisely because one has not experienced it in person, one tends to “underestimate” the energy that was spent to achieve a result. The E-Cat EV Demo certainly required a very high investment in terms of “personal energy” but the epochal result that it achieved deserved it ALL!!
It is my intention, even if the time I will have available will be very little, to provide as many testimonies as possible of what was done to arrive at the demonstration of the Ecat-EV.
I’m providing 4 photos and a video
The 4 photos, taken today in my box/laboratory, show the main box of the E-cat interface to the Twizy (actually in the Twizy there is also another board with my SW components, but that is not easily reachable and therefore I think it must only be imagined 😉 ) and it is the heart of all my integration.
It takes as input what comes from the E-Cat (2 of the connectors, black and orange, automotive 1000v 120a ip67 quick release that you see in the photos) and receiving as input from the circular connector the Twizy canbus (the heart of everything that happens inside a BEV, part of that data is interpreted and displayed by my active apk on the cell phone that you see in the photo. The Twizy was on at that moment and via bluetooth my application was receiving real data), it does all those “necessary calculations” and those “energy manipulations that ensure that exactly what needs to enter the battery enters (the other 2 automotive connectors equal to the previous ones that you see in the photo)
The 2 Management consoles positioned on the right of the photos, allow me to check at any time the “energy behavior” of the entire system, as well as the temperatures of the electronics themselves for optimal management (just to give an efficiency figure, the performance of the entire management system is of the 98%, that is, I can put 98% of the energy that the E-Cat provides me into the Twizy battery, energy that is completely under my control.
It is thanks to this control panel that in the last lap (which Dr. Rossi and I “consciously” decided that I would do) by acting on a certain number of parameters I was able to recharge the battery from the 63% that I had decided to maintain up to that point (energy balance between energy put into the battery and delivered by the battery to the inverter) to 83% where I wanted to stop so as not to stress the battery itself.
As I already wrote in my response to an E-Cat World reader, I could have immediately brought the battery to 100% of SoC (the E-Cat was configured to be able to provide much more energy than necessary for the demo) but I would have only harmed the battery of my Twizy.
Having explained what is seen in the 4 photographs, we come to the details of the video.
This video was made before positioning the E-Cat in the twizy (to do so it was necessary to dismantle the entire seat and the sliding guides). Once the seat and the guides were removed, unfortunately you are NOT faced with a flat surface, but unfortunately irregular. Having the E-Cat a “not negligible” height it was impossible to think of positioning it directly in the rear part. In order to facilitate the maneuver, I was forced to invent that wooden platform that you see in the video. A platform that makes the support surface regular, thus allowing the “sliding” of the E-Cat directly into its final position. As I said, I had to invent that solution, and not only invent it but also make it myself, even in this case with considerable expenditure of time (fortunately I know a little about carpentry …. ).
Even for the E-Cat support base I had to do a fair amount of calculations to ensure that it did not receive excessive vibrations or backlash while driving. Under the wooden base that you see in the video there are 2 rubber bases with “controlled” absorption so as to dampen and reduce shocks and vibrations at “specific frequencies” of the automotive.
The cell phone and the control box that you see on the “dashboard” are the ones I gave the details of before, the power cables that as you can see become part of the “Twizy system” (as also said these Automotive of 25mmq certified with 120A male connectors) are the ones that take the output from my Electronics bringing everything to the Twizy battery.
The E-Cat that obviously is not seen here has the same type of connections that therefore also “plug in” as Input to my Electronics.
I would say that this is all, I sincerely hope I have managed to satisfy the “curiosity of many”
