Hi I want to ask that if the toyota camry hybrid 2011 car's hybrid system is not working anymore. In future Can we still drive it normally on fuel? Thanks
Hi Hussain,
Does the car start and run? The Toyota Camry Hybrid uses the MG1 (High Voltage Motor-Generator Assembly) to start the engine, so the engine can be started only with the high voltage system. For reverse "gear" the computer simply reverses the phase sequence to MG2, so the car is propelled only by electricity in reverse. However, if the car is throwing a code such as P0A80 (Replace hybrid battery pack) it can still be driven, the engine will just be running the whole time and the acceleration will be very awkward. Most acceleration from 0-10 or 20 mph is done with high voltage (through MG2). But some codes will not allow the car to even start.
The Toyota Camry Hybrid drivetrain is perhaps built around the Hybrid Synergy Drive system more than the engine. I do not recommend trying to drive the car without the Hybrid system in good working order. If the HV battery is only getting weak and unbalanced, I recommend the Prolong Battery Reconditioning system, which uses cycles of charging and balancing, then discharging, then charging and balancing, then discharging, then charging and balancing, etc., to rejuvenate the battery cells to proper performance. I am very happy with the results of this system on my 2007 Toyota Camry Hybrid.
Good Luck!

Hey cj1,
So I got the Prolong® Deluxe Reconditioning Package, which is $693 for the 2007-2011 Camry Hybrid, from the Hybrid Automotive Company. This setup has a smart discharger, whereas the Value Package ($479) uses incandescent light bulbs to discharge the HV Battery.
I really can't say how much it improved my Miles per Gallon, as I did not do much driving with it before, but I know it is in electric mode a lot more, and can accelerate more without the engine starting. And it regenerates a lot more watt hours of electricity now. The car was throwing a P0A80 Code every once in a while before since I got it in September 4 months ago. I did take the battery the whole way out and load test each of the 34 modules (with Hybrid Automotive's module load tester for $79) and replaced one (individual modules available from Hybrid Automotive for $46) that had significantly more voltage drop than the others. I put it back together and only had time to charge and balance the battery before a 2,000 mile road trip a week and a half ago. The car acted perfect the whole trip and I got around 37 mpg without taking it easy. I just did a cycle of discharging and charge+balancing since then, and I am running another 1,800 mile trip this weekend. I don't expect better than 37-40 really, but I will update this post if I can remember to!

No. There is no solution to this.
If your hybrid battery drained or died, which is rare but not unheard of, you will not be able to start ICE as MG1 does not have power supply.
Pretty much, it is safe guarded so much, that when battery is at the danger of complete discharge, your car will brick. To save it.
As of how much it costs to use Prolong, go to their website and look it up.
I always suggest to go first hand knowledge, instead of listening to opinions.
Dealer can recharge dead hybrid battery also. If it's rechargeable.

See my post above for cost, etc.
is the link to the website of the Hybrid Automotive company, who makes and sells Prolong Battery Systems.
