car energy consume improvements

I'm afraid to assume that this is one of Dr. Holcomb's devices "Boost Converters" ?

Don't assume anything. Have a quick look at the attached PDF's - then you'll know for sure!

It's been an on-going common design challenge for a while already... And not just for EV's - lots of
innovations like this are happening all throughout industry right now. Quite exciting actually!

Some very good $$$,$$$ to boot; if you're an experienced consultant/contract designer/developer
in this area... long term, also.   Plus - you might just discover some "excess energy" along the way!

Hey, like I've promoted many times - get that Engineering and CAE course work behind you ASAP...
unless you want to spend another 10+ years talking nonsense and babbling on these forums!

So, I'll assume none of you guys know (or can figure out) whether these Boost Converters
have any "Gain" associated with the designs.

As shown yes there is a gain in efficiency.

Coincidentally, I don't have a bench power supply and build my own buck/boost/cuk DC/DC converters as needed. There really simple and I have probably build hundreds. I prefer using a micro-computer with PWM, low resistance mosfets and fast switching diodes. I have also used synchronous rectification before but it's seldom necessary. I often test HV circuits above 30kV+ which could feedback through a ground connection so a cheap purpose built converter is a must.

On your post, the gain is obvious and the higher the voltage in the working circuit ie. motor the lower the heat/resistance losses. Simply put doubling the voltage cuts the current by half at any given power level. The current flow produces the heat/resistance/copper losses not the voltage. So it pays to use a converter to run a HV motor well above the battery pack voltage in EV's.

Most people don't get this because they don't understand the concept of energy.

Power is Volts x Amps, so 10,000V x 1A= 10,000 watts and 1V x 10,000A also equals 10,000 watts. However the low voltage/high current power would have magnitudes higher losses than the high voltage. In effect, anyone running a motor or any electrical system at low voltage/high current doesn't understand energy or efficiency.

For example, an incandescent light heats the filament to incandescence to produce light. It generates 80% heat and 20% light which is absurd. Where an LED excites the material causing oscillations which emit a given wavelength of light and minimal heating. Ergo, large heat losses in conductors or circuits is generally a sign of incompetence.

The Tesla hair pin circuit is a good example of what's possible. There were people lighting a 100w bulb underwater with tiny 30 gauge conductors. The trick was the blocking capacitors on both circuit legs which limited the current flow. The energy flow is high but the current flow is very low which many people have trouble wrapping there mind around.

"Simply put doubling the voltage cuts the current by half at any given power level"

If this were a "Transformer" device, I would agree (minus the losses); but this is a "Boost Convertor,"
not a transformer, [plus 200-300 Vin - 400-800 Vout].

This is the mistaken assumption most (all) guys made when evaluating the Holcomb devices!

Anyway, I'll just leave it there...

HINT:

As you study the various "Convertor - Invertor" topologies found in the papers, keep in mind
they generally involve a single inductor with  a single winding. Although some authors do mention
the B-H Curve, they are usually concerned with only the inductance and not magnetic gain aspect.

Recall - a small "H" can induce a large "B" in a "soft magnetic material." This is where some
significant "magnetic gain" can be achieved. Combining this "knowledge" with a Boost Convertor
might have some significant effects!  This has been proven in the Holcomb devices.

Further, combine a B-H Curve related Boost Convertor with an Inverter topology... (as found in
modern high RPM [many pole] ICE generators that employ an inverter [keep the inverter input
capacitor charged - KHz]

Just a little "food for thought!" This is where a good CAE Analysis platform is handy... a quick try
it out before spending money on a brass-board prototype.

Good luck and happy designing!     Anyway, enough of this chatter....

Toyota has néw ammonia engine which they say will bankrupt EV industry

Also Ford has some ammonia engine in the works
Reason =Zero Co2 emissions using ammonia


Yeesh ammonia......;(
