i think its a demo screen. the battery is nearly at the bottom of its charge range. in normal circumstances, that would not happen. actually you can make your Prius do the same thing. just start the car, put it in park and turn on the air conditioning and you will get the same situation. i dont think you will get the arrows though although i maybe wrong.
If you're stopped, but have the foot only lightly on the brake, you'd get 0 mpg, but still have arrows flowing for "creep" mode. As for th EV switch, hdrygas - where you sight this?
Just guessing because the battery is low. Probably only available everywhere but the US, along with the sports suspension. I am not bitter though. Nope.
as an interesting aside to Rick's statement about not pressing the brake pedal all the way down. In my Classic today I noticed that when the display shows power flow but your stopped the current draw on the system is 3.2 amps but if you press the brake firmly and shut off the power flow it drops to 1.7 amps draw.
The Highlander has a second elec. motor for the back wheels. I thought that this one would have it too. Huh?!?! :roll:
As I have DRL's I suspect that it's part of the output to keep the battery(12V) in it's normal range of charge. And the traction battery was running at 297Volts at the time. I've never seen it under 289 volts. BSOC 62%
Wow, so 273.6v is nominal on the '02? Was anything else running - such as blower motor, radio, etc? I'd love to see actual data on the '04 - haven't followed it - has someone done a scanner with it yet for voltage, etc.?
the classics did have higher voltage batteries... 38? or 34?( i forget) modules as opposed to the 28 in the 2004
38 is correct. Each "cell" in a NiMH battery has a nominal voltage of 1.2v. Each Prius "battery" module consists of the equivelant of 6 1.2v cells, for 7.2v each (should sound familiar for R/C car buffs). Multiply that by 38 modules and you get the 273.6v rating of the '02 pack. Using the same math, we get 28 modules at 7.2v each, for a total of 201.6v for the '04 Prius. The inverter does the step-up to up to 500v. Using similar math, it could stand to reason that at a higher state of charge (SOC), the '04 battery could sit as high as 218-220v. Anyone w/ a meter want to confirm this?
the only thing running was the DRL's as it was a nice day and I had the windows down enjoying the fresh air. I had just climbed the big hill when I got this data. The highest voltage I've see so far is 340 volts just as the BSOC hit 80% and then it cut to 322 as I couldn't regen anymore. If I went out to the car right now , 4 hour rest on the battery, I'd just about guarantee you 295 volt or better. Tomorrow morning after an overnight cold soak probably 285 or better. The interesting data is for the MG temps. Hill climbs etc. Also when your accelerating up a big hill it's still putting 3-4 amps into the battery. Only time I see the amps dropping along with the battery voltage is when I'm in stealth. If the ICE is running it's charging the battery. Yesterday I did hit 60 amps on regen down the big hill.
