#381 of 393 Re: And when the battery's Empty? [backy] by stevedebi Mar 17, 2005 (1:33 pm)
Replying to: backy (Mar 17, 2005 11:20 am) "Under what real-world conditions would anyone be driving a Civic hybrid or Prius with an empty battery?"   We should note that is a depleted battery, not empty. The Prius won't even start if the battery is below 20%.   The HCH, of course, will just run more slowly. Replies to this message: midnightcowboy (Mar 17, 2005 1:44 pm) backy (Mar 17, 2005 3:36 pm)

Replying to: stevedebi (Mar 17, 2005 1:33 pm) Hills, Mountains and inclines come to mind! It is hard to flatten out the Rockies, it they happen to be in your trip path.   And then ,there is the potential future problem, Battery failure! Maybe just a cel or module, but failure of the traction battery system. Most cars are too new to experince this yet, but fast forwre to 2010 or 2015 and this will be a big discussion topic.   In fact, you might not see a total failure, but you might eperince the partial charge sysndrome, wherby the traction battery under the best hyper mileage conditions will only maintain a partial charge, maybe 90%, maybe 80%, Maybe 70%. who knows. If so, then maybe it would deplete under normal driving.   Anyway why worry, if it happens it happens, I heard one Prius advocate expounds that the battery will last for ever becuase it is almost never used! Maybe it will and maybe it won't   Good Luck and best of wishes,   MidCow the Manual Shift Man Replies to this message: backy (Mar 17, 2005 3:36 pm)

Replying to: midnightcowboy (Mar 17, 2005 1:44 pm) OK, I guess there are lots of times you will climb a mountain, then at the top (before you've gone downhill and recharged the battery), you need to floor the accelerator do a full-throttle 0-60. That happens all the time, right?

You asked how a battery could get completlely discharged and I stated: 'up a hill , mountain or incline.'   I said absolutely nothing about what you would do with the car following a depleted battery. I said nothing about flooring the accelerator or doing a full throttle 0-60 mph on a depleated battery.   However, as pointed out before, maybe too subtlely, when you have a depleated battery state, then you are vulnerable to extremely poor acceleration and potentially this could be a safety factor.   Again, I was only answering the question "How could one ever get a fully depleated battery?"   YMMV,   MidCow   P.S.- My Honda battery just gave out and I had to get it replaced $21 with tax and installation. Now I can start my 5-speed , becuase it is mowing season and the grass needs to be cut Replies to this message: backy (Mar 18, 2005 9:38 pm)

Replying to: midnightcowboy (Mar 18, 2005 8:05 am) I didn't mean to imply you said anything about flooring the accelerator or doing a full-throttle 0-60 on a depleted battery. But that's exactly what MT did in their tests with a depleted battery--did full-bore 0-60 tests. I was just questioning how realistic that is. Especially in the Midwest, where even big hills are few and far between. From reading the hybrid discussions here for the past couple of years, I get the impression a fully depleted battery is very uncommon under normal driving conditions.

How realistic are 0-60 numbers, period?   troy Replies to this message: backy (Mar 24, 2005 11:19 am) gagrice (Mar 24, 2005 11:37 am)

Replying to: electrictroy (Mar 24, 2005 10:16 am) Good point. How often does someone really need to go 0-60 at full throttle? I can count on one hand, with fingers left over, the times I've done that that in over 30 years of driving. And I'll bet I really didn't have to do it, when it comes down to it. Passing acceleration is more important in the real world, I think. Replies to this message: gagrice (Mar 24, 2005 11:37 am)

Replying to: backy (Mar 24, 2005 11:19 am) I totally agree with both of you on this one. I guess that is why I question all the hoopla over high powered hybrids. The HAH has as much HP as my Suburban, that is twice the weight. A Waste of energy IMO.
