Updated FAQ with Toyota URL -- suggestions?
Hi folks,
An unofficial FAQ editor, I've just added the following URL to the Prius FAQ: I am interested in making this a living document. But I don't have much information for the Prius II, NHW20 model. If someone would like to draft some sections unque to that model, please add them to this thread. After suitable comment period, I'll put them in the main FAQ with attribution. IMHO, something about the Bluetooth-phones and/or how to make the radio 'play nice' would be a good addition Regardless, my ears and eyes are open. Thanks, Bob Wilson |

Hi Bob,
Thank you for the link. Have you ever seen following presentations? They are placed on John's site, but they are written by Toyota engineering. Toyota Hybrid System for 1997 original Prius http://john1701a.com/prius/presentat...ntation_01.htm 2004 Prius http://john1701a.com/prius/presentat...ntation_01.htm Ken@Japan |
Re: Updated FAQ with Toyota URL -- suggestions?
Thank you Ken.
I've added the links under the definitions. I'll probably go back and make it a little cleaner but they are in the right areas for now. Bob Wilson |

According to this slide Toyota was already on the ball with plug-ins when they made this.

Re: Updated FAQ with Toyota URL -- suggestions?
Check transaxle oil early and replace if contaminated or discolored. Early results from an NHW11, Amsoil ATF experiment suggests an annual change or ~11,000 mi., will correspond to the worn out, 15% decrease in viscosity (31 cSt @40(C)). NHW11 uses 'Type T' and the NHW20 uses 'Type W'. Keep the filters clean or replace frequently. Fleet reports suggest the NHW11 models may need to have steering assembly checked frequently. In cold weather, an engine block heater can save nearly 100 ml. of gas due to faster warm-up. Check the throttle assembly every 50,000 miles for butterfly soot. Get a tire gage and/or fill with nitrogen. Keep the tires as hard as possible, 42/40 works for most tires but always ask. The front tires need to be 2 psi harder for proper handling and best ABS operation. that's all for now, hopefully your Faq will encourage more classics to live. |

http://www.toyota.co.jp/en/news/06/0613.html This is the first time I saw Toyota's official announcement about the plug-in hybrid. Is there a Japanese version of the GreenHybrid database? Remembering the roads on Okinawa (maybe not the best example,) I was wondering if the Japanese Prius drivers are getting significantly better performance than we see here in the USA. From what I remember of Okinawa, any Prius should should get stellar performance. Bob Wilson |

One question I've been meaning to ask: Is there a Japanese version of the GreenHybrid database? You're welcome. Yes. There is one, but members are not so many... http://eshy.s22.xrea.com/cgi-bin/nen...?category_s=20 Sorry for the Japanese only. 1st column: life time mileage 2nd column: single tank mileage 3rd column: single tank distance Ken@Japan |

Hi Ken,
This is perfect:

http://eshy.s22.xrea.com/cgi-bin/nen...?category_s=20 Sorry for the Japanese only. 1st column: life time mileage 2nd column: single tank mileage 3rd column: single tank distance Japan: 58.2 mpg - average for middle 50% (78 total samples) 58.8 mpg - median for middle 50% 3.4 mpg standard deviation - for middle 50% USA: 47.7 mpg - average for middle 50% (684 total samples) 47.7 mpg - median for middle 50% 4.4 mpg standard deviation - for middle 50% This agrees with my expectation that USA driving and traffic patterns hit the weaker performing speeds of the Prius. USA drivers tend to have more time in the MG1 transition range and at speeds higher than 65 mph. We also do not have the EV control. This tends to reduce USA Prius MPG (km/L) performance relative to the excellent Japanese performance. Thank you again for pointing us to this great data. Unfortunately, my Japanese is not up to the mark. Could you please share my thanks along with this data to the members of the Japanese Prius database? Bob Wilson |
GREAT STUFF-THANKS!!
Bob,Phil,Ken,Schwa- great stuff.Thanks.
Anyone have any idea of the cheapest way to add a second battery/battery pack? You guys know that biggest boost in FE would be to add maybe 3000 Watt Hrs (2000 useable, maybe 3000 ) and the EV button with plug in capability. This would give ~ 10 mile low speed all electric (10 cents per 1000 WT HR) capability. You could do 10 miles at 2 cents per mile instead of the 6 cents a mile a 50 mpg Prius gets with $3 gasoline. I know that there are a couple of expensive ($5000 and $10000) kits, but the cost is too high. Any of you engineers planning to DIY one of the kits? I'm fairly sure the Lead Acid batteries would weigh only 300 lbs and cost just $300. The EV button is just $50 from Coastal. The frame would have to be reinforced to handle 300 lbs of tongue wt. I would be reluctant to have the batteries in the passenger compartment, so maybe you could add a receiver hitch and carrier and carry them behind the car? If I was more electrically adept-and the Prius was out of warranty-I would give it a try. For brave souls still in warranty, the batteries on the carrier would allow a quick return to OEM configuration just in case you had to bring it in for warranty work?? Maybe this is the wrong thread to post this in, but this would allow a 1st gen Prius to absolutely KILL all other cars in FE, giving it the equivalent of 100-150 mpg -an Insight Killer. This is the real advantage of Toyota's system over Honda's system.Granted hauling 300 lbs of batteries with them protruding 2.5 ft isn't elegant, but it would certainly help the city FE.A quick D/C could be used to put the Prius back in Hy trim(or warranty trim). A HH would be a natural for this treatment. It would require maybe 500 lbs of batteries to get 10 mile range. I don't see any reason to try to make them rechargable by the ICE or regen-too complicated.Just "trick" the control unit into thinking it is in EV mode, and just draining/using its own battery. Sorry to step on the thread.Great stuff posted in the FAQ Bob!! Charlie |

I have some plans but I'd prefer not to 'muddy up' the waters of this thread. But there are several technical challenges: - avoiding triggering a ground fault - a modular approach so you don't have to deal directly with lethal battery packs - non-battery, electrical power source, a compound engine approach - getting the EV switch modification I was thinking this would be a nice project for my second year of Prius ownership.
