Replying to: gagrice (Nov 04, 2004 11:05 am) Yup. Ovonic filed the lawsuit anyway. I believe Panasonic EV could of fought it and won but it would delay Prius and other HSD car production. It was the best interest for Toyota to settle it ASAP. Maybe that's how Ovonic took the advantage of the unexpected 04 Prius demand. Dennis |

Replying to: railroadjames (Nov 03, 2004 1:50 pm) I believe that Cailifornia mandated 10 years and 150,000 miles. 8/100K is the Toyota warranty.

Replying to: stevedebi (Nov 12, 2004 12:11 pm) That is the way I understand it. My question is if the car has a problem in CA at 125k miles. Will the State of CA force Toyota to fix it. The car is required to get AT-PZEV rating, that it maintains the same level of emissions for that 10 yr 150k miles. So if the battery or electric motor or ICE dies it will not maintain that emissions level.

I'm an electrical engineer, and I did a lot of research before I bought a hybrid. Based upon what I uncovered: - the battery in a hybrid will last as long as the engine (~250,000 miles) - unless you abuse it (lots of stop-n-go) The reason the battery can last so long is because the hybrids barely use it. Lack of use = lack of stress = long life. Troy

Er, yes, but no not really. NiMH Battery chemistry is weird. If you exceed 90%, or drop below 60%, you stress the battery and cause damage. That's why pure electric cars have to replace every 100,000 miles... they damage their battery from overcharging/emptying. . The hybrids only use the "sweet spot" between 60-90% in order to avoid battery damage. They are only using 1/3rd of the battery, but that extends its life to >250,000 miles, and eliminates replacement cost. Plus like I said, hybrids barely use the battery. 10 seconds to boost 0 to 60, 1 second boost to climb a small hill, 10 seconds to slow down. The amount of time my Insight uses its battery is <1% of the total trip. Troy

quote-"If you exceed 90%, or drop below 60%, you stress the battery and cause damage."-end quote If that is true, then my 2004 HCH is damaging it's battery every day. I drive city miles only (very few exceptions in the first 4 months) and my battery charge indicator is ALWAYS hovering between 5% and usually around 20% unless I get on a long road with no red lights and set the cruise for a while, then I can get it up above 75%. |
