Replying to: wvgasguy (Jun 18, 2006 4:14 am) What's your current avg mpg? Do you drive on level ground at low speed limits? Have you went up any long or down any long steep grades? I guess what I'm getting at you may live in an area that is "in balance" with the nature of the car. No extremes may keep your car in the sweet spot.   You're probably right.    Find a steep grade (1 mile or so_up or down) and watch the battery. It should either discharge more or charge more.   I did that, and the battery was charged to all the way to Level 8. After I got on back on level ground, everything settled back to Level 6 again.   Thanks a lot for your help! Replies to this message: wvgasguy (Jun 18, 2006 6:45 pm)

On a long drive it will turn purple if you go low enough before the engine will kick on to charge it.

Replying to: jan123 (Jun 17, 2006 10:08 pm) The design of the HSD vehicles is that the battery is never fully charged and never fully discharged. The SoC is limited to a narrow range so the battery doesn't deteriorate and need replacing.   You are in good shape.

Sorry to change the subject, but I have a Question... ... if one has a Hybrid for 14 years and the Hybrid battery refuses to charge, dies, or is removed ... then can one just drive the ICE until you replace the Hybrid battery? I assume there are two batteries, one for the Hybrid and the other for starting the car.   Gampa Replies to this message: r_nash (Jun 17, 2006 7:22 pm) stevedebi (Jun 19, 2006 12:06 pm) gampa (Jun 20, 2006 5:08 am) grandtotal (Jun 20, 2006 7:43 am) stevedebi (Jun 20, 2006 12:50 pm)

Replying to: gampa (Jun 17, 2006 6:54 pm) If the Hybrid battery dies, you can't start the car. The 12 volt batter just boots the computer so it can start up the inverters. Without the inverters running, the Hybrid Synergy Drive can't run the 2 electric motor/generators in the eCVT to start the engine or move the car.   Ron

Replying to: gampa (Jun 17, 2006 6:54 pm) The Honda IMA system can run without traction (main) batteries.   The Toyota HSD system cannot run without traction batteries. Replies to this message: gampa (Jun 20, 2006 5:08 am) grandtotal (Jun 20, 2006 7:43 am) stevedebi (Jun 20, 2006 12:50 pm)

Replying to: stevedebi (Jun 19, 2006 12:06 pm) OK then theroretically...Toyota specific... as long as the "non-charging" Hybrid battery remains in the car it should run the ICE all the time and reduce your MPG to the 23-25 range from 35-38 range. This way you can drive the car until you have the money to buy the more expensive Hybrid battery.   Does this sound correct?   Gampa Replies to this message: grandtotal (Jun 20, 2006 7:43 am) stevedebi (Jun 20, 2006 12:50 pm)

Toyota hybrids work in a totally different way than other non-HSD hybrids.

The car will not run at all.
#20 of 96 Battery guage never gets to full by joystix2 Jul 24, 2006 (8:53 pm)
Another newbie here. I just picked up my red Camry Hybrid over the weekend and put 300 miles on it already in 2 days. Boy this is a nice riding Hybrid and roomy too. It's been very hot here in the Bay Area California these past few weeks (100+ degrees). My question is that eversince I drove it off the lot my battery guage has never been topped off. Does it take a few weeks before the battery fully charges from the regenerative system? Replies to this message: wvgasguy (Jul 25, 2006 11:03 am)
