Charge time

The PIP's charging system automatically charges the battery then when the battery is fully charged the charging system shuts off. You can't overcharge the battery.

 

Overcharging Lithium-Ion batteries can have catastrophic results (fire/explosion). Thus, the chargers for these batteries have had to be "smart" charging systems from the start, whether you are talking about cell phones or cars.

 

Toyota recommends using the built-in charge-start timer to delay charging so that the car becomes fully-charged just before you next use it. My commute starts at 9am, so I set my timer (one button-push on the dash, it remembers the prior setting) to start charging at 5am.

Apparently the battery ages faster if left fully charged.

 

I don't believe that's entirely true. I have a Dell laptop with the original battery in it from 2009 and it still lasts 3 hours. The charging system in my Dell Laptop doesn't trickle charge the battery if the battery has a full charge. I believe that's why the battery has lasted five years. I have my laptop plugged in all the time. I turn off the power strip at night, then turn it back on in the morning every day.

 

Why would the manual tell you not to leave it charged for very long? And why would it still burn off EV when switched to HV right away?

 

I don't know. And I have been driving in EV for a long time not switched to HV.

 

I don't think you understood my question.

 

yeah, you're right, it didn't make sense.

 

From a full charge the PiP will operate in EV assist mode for a few miles even when you're in HV mode. It's not possible to start from a full charge and bank that charge for later use.

 

Again, that doesn't make sense. For instance, I just drove to Subway which is a mile away from my apartment, came home, Started with 9.5 EV miles, I now have 7.5 EV miles left "for later use" I have been driving in EV for two years now and nothing has changed.

 

You still aren't understanding.

He means when you switch into HV. You clearly aren't switching into HV.

 

I don't think "it" burns off EV because when you turn off climate control and ICE turns off EV goes back up to the previous mark minus the amount of EV that was used during traveling in HV. And traveling in EV doesn't burn off to "protect" against being fully charged.

 

When in EV, ICE does come on after about 124 miles to "exercise" ICE not "burn off" EV.

 

lost cause, I'm done

 

Oh! chill!
Congrats! Big Red. On B Ball WIN!
Sad Badger!

 

if you plan on keeping the car more than a few years and 75,000 miles, use the timer.

 

So charging from say 7-10:00pm, fully charged for 8 hours, and driving at 6:00 am does reduce battery life over time?
Does it reduce the Kwh's of charge the traction battery is able to hold, shorten time until it will not function, or both?
Tks.

 

No one really knows....yet.

 

iirc, the manual recommends completing charging as close as possible to using. not sure exactly, but something about a fully charged battery is detrimental. once in awhile is probably no big deal, but i wouldn't do it on a regular basis. and toyota doesn't warranty battery degradation.
