another new document for Prius... ENERGY

john1701a · 04-16-2005, 06:47 PM

Just like the "for newbies" document on the PSD, there is now one in the works to describe the ENERGY-FLOW that takes place in Prius.

Here's where you'll find it... http://john1701a.com/prius/prius-energy.htm

It's currently in draft form (the image & labeling complete but no text to explain the flow added yet).

Let me know what you think. The goal is to keep it as simple as possible, with the intent of it being used as an introduction to the technology. And yes, I plan on using it at 2 different "Earth Day" events I'll be attending with the Prius next weekend. So the missing text, and the resulting feedback, needs to be completely rather quickly.

Thanks in advance.

I think it's plenty simple enough. I guess the only thing that comes to mind is that It isn't quite as obvious to me that the PSD actually ties all 3 'power sources' together just by the diagram. That said I sure can't think of a better way to do it either.

The money of this diagram will be the descriptive text...I think understanding the different jobs of MG1 and MG2 at different times is the hardest part of the concept for folks to get...and remember.

What if you kinda encircled the PSD with the ICE, MG1 & MG2....

I've got a picture in my head, but I'm at work and don't have the photoshop know how to make a picture.

The text is now available... as shown in the dynamically updating image above.

Toyota now use the term "Power Booster" instead of Inverter. This is exclusive only to HSD and I believe Ford full hybrid does not have the booster.

Another thing I notice is that you refer to MG1 as 10kW. Are you sure? If battery pack is 21kW and MG2 is 50kW, I would say MG1 is at least 29kW. Otherwise, MG2 would never reach it's max power.

You might want to include the small 12v Lead acid battery there as well. It would have one direction arrow from the booster to 12v.

Looks colorful with a nice layout but the font is too small - I can't read it nor enlarge it!

"Power Booster"? Maybe they've called it that in a public brochure or something, but the repair manuals, and NCF still call them Inverters. I'd stick with that terminology.

I think including the 12v is a good idea to help people understand the 2 battery concept...there could be a second arrow from the 12v to "accessories" or something.

John,
On the diagram, you need to show the flow to the wheels also.
Evan's suggestion re using a "circular" format, with the PSD at the centre, is worth trying.
Also, I suggest the use circular symbols for the ICE, MG's, PSD and wheels, with the other bits as rectangles.
It's difficult to explain the concept of a motor/generators to non-technical people, but it's necessary to be able to understand "regenerative".
Keep up the good work - accurate education is the best means of "spreading the word"!
Hopefully we can all contribute in some way.

John, what about colored arrows ...preferably the same color as on the Energy Screen display. Might translate a little better....you'd have a too and a from arrow from most of those.

I also have some suggestions, corrections, additions to suggest on the text, but I'm gonna have to sit down and think about it more carefully and check my facts first.

For one, though, I'd make sure to show that you're talking about the THSII at the top. Also, I think the ECU regulates energy flow 10-20 times per second, not per minute.
