What would happen to Prius with dead battery pack?

if the truth was know I'd hazzard a guess that neither the of them will even start. The nomal boot cycle will realize that the HV battery is dead and that will not allow the computer to start the car. The slow degradation of the battery pack will slowly raise the fuel consumption but will we be able to tell? long term spread sheet info will probably signal it, if your still keeping records at that late date.

 

So you're in a stop and go situation the engine will start and stop everytime ?

Sounds like a lot of wear on the engine.

 

If the engine is warm, Prius does the same.

But oil pressure is provided to the engine before combustion starts, so wear is minimal (for a Prius, no idea about the HCH).

 

My 04 Prius keeps showing 2 or 3 pink bars in the battery box on the Energy Monitor. I will get full green bars when I go down hill in B mode. What does this mean? Glad to hear I may never have to replace the battery pack. I always heard the pack ran around 4800$




QUOTE=jeromep;181361]I wouldn't call that an advantage. Anyone who owns a hybrid knows that the battery is an integral part of the vehicle in all aspects, or else it isn't a hybrid. The logic of being able to drive a hybrid without a battery makes as much sense as driving a conventional vehicle without a functioning transmission. A vehicle stuck in 2nd gear isn't very good for much; a hybrid without a battery isn't a hybrid and isn't much of a vehicle either.

What hasn’t been pointed out is that Toyota’s battery management system protects the battery and works to prevent memory effect, which is the biggest danger to battery life. Very sophisticated sensing technologies work to prevent memory effect and to eliminate it if a memory situation starts to occur. So far, any battery issues that have occurred on Prius have been on 1st gen vehicles and on top of that there is no documented situation where an owner was fully on the hook for a battery related issue.

The tuning of the Honda engine for hybrid use doesn't lend itself well to sans-battery operation. In addition, without a functioning battery it is carrying around a lot of dead weight, in the form of a flywheel with an electric motor grafted to it and a battery pack that is not providing any contribution in this scenario.

So, following with my example of transmission failure. How much is it to go through and fix a dead transmission on an otherwise good vehicle? $1500-2000 in many instances (a lot less expensive than purchasing a new car). Estimated cost to replace a battery should it ever happen, and that is unlikely, $1500-2000. However, I cannot stress enough that the likelihood of this happening is beyond slim. You are more likely to spend money to fix an auto trans than you are to spend money replacing a battery in a Prius.

So, the Honda's advantage of operating without a battery is a pretty lame excuse to support an unimpressive hybrid platform.[/QUOTE]

may be the closest independent garage that advertizes Hybrid battery replacement. I expect under half your estimate.

 

I can definitely help you out. I sent you a PM.
