Should Dianne Charge my PiP to only 1/2 for shipment to me???

    Dianne states that she will make sure that each new PiP leaves Carson Toyota with a full tank of gas and a fully charged battery.

    My car will be shipped from Carson, California to Minneapolis, Minnesota and this journey will take close to a week.

    Would it be best, for the health of my new PiP's battery, for Dianne to only charge my battery to about 50% (not fully charged) for the trip to Minnesota?

    Nah, fully charged is fine.

    Why wouldn't I charge every car fully?

    Make you a deal. If you prefer it half empty, I'll send it with no fuel and use your gas for my own car! :eek:

    Re: Dianne Charging Only 1/2???

    Because Toyota says in the Owners Manual to "Use the charging timer function as much as possible in order to fully charge the hybrid battery (traction battery) IMMEDIATELY BEFORE STARTING OFF" (emphasis added). See page 93.

    If a car is being shipped, I believe Toyota is saying to wait on charging until the car is put in use by the new owner.

    I have asked for Toyota to tell me if the reason for avoiding EV speed near the maximum of 62 MPH, another point made on page 93, is to prevent degredation, or long term weakening, of the traction battery, but have not yet received a reply.

    It's better for longevity to allow the battery to "cold soak" before recharging. In other words, let it rest after usage. The timer makes that easy to accomodate.

    And for those of us in the north, we'll benefit from the little bit of warmth recharging causes rather than starting totally cold.

    Look, it's a good idea to develop good charging habits during the life of the vehicle to maximize it's life. But you're not going to do any harm by occasionally "breaking the rules". Fully charging before shipping from California will result in a tiny amount of drain/loss, but I bet it's still nearly fully charged when it gets there. Top it up before driving if you wish, but don't drive yourselves crazy thinking if you charge it up then don't drive it for a few days that something horrible is going to happen...it won't.

    I know it's a brave new world for many, but Toyota has built a reliable vehicle that you're going to have to work pretty hard to mess up. Don't over think it, just enjoy it.

    Oh wow! I thought it meant Diane is only charging 1/2 commission. :rolleyes: I would have said sign me up!

    Re: Dianne Charging Only 1/2???

    You PiP battery should be fine.. Hopefully it is like my Volt, and 100% charge is not "100%" of the batteries total capacity... That is the one thing you should think about in terms of the battery.. It is not 0-100% like you would think.. In the Volt 0% displayed is really 40%, and 100% displayed is really only 80% of the batteries capacity... I am sure the PiP operates the same way to prolong the batteries life..

    This is the reason Nissan tells you not to charge the Leaf to 100% all the time unless you truly need it as it shortens battery life. Because on the Leaf 0% displayed is really 22% , and 100% displayed is really 100%.. So they recommend if you don't need it to only charge to 80% capacity to extend battery life.. Tesla also has similar recommendations on the Roadster. Those are full EV's though, so the same rules should not apply to you.

    The thread title was a little sneaky, a play on words to draw you in... :rolleyes:

    I think it'll be fine to charge it full and then ship if it's going to a northern state in the (still) winter. Toyota is more clearly concerned if it's summer and the battery is fully charged and not being used.

    As I've mentioned elsewhere, my Tesla owner's manual says to use "Storage" mode (where the battery is kept below 1/2 SoC) if the car will not be driven for more than 2 weeks.

    Assuming similar protocols, your PiP should be fine with a normal charge for the week it takes to reach you.

    Re: Dianne Charging Only 1/2???

    Maybe not. If the truck is moving (as it likely will be) there will be highway-speed wind flowing around it. This will help cool it, preventing the car from getting much hotter than the ambient air. A parked car in the sun can get much hotter than ambient.

    But I wonder if the shipper (Dianne, in this case) can request a lower-level position for the car.

    Tesla shipped my car to me in an enclosed transport. It had a fancy hydraulic lift to allow cars to be raised to and lowered from the upper level. But of course Tesla is a classy company. ;)

    John

    This post and the one following by Evan raise an interesting and perhaps important issue. If I always plug in (and charge) when I get home from my usual short trip is that good? Or should I wait until night to charge and risk the possibility of a deep discharge in the process? I tend to worry more about the possibility of a deep discharge which could result from several short trips in a day without charging. But the battery management system of the car may prevent that so what is the best habit to get into considering that frequent charging is much better for a battery?

    I am inclined to plug in when I get home every time. But an alternative is to always set an hour delay for charging to cool the battery. I note that my '06 always charges on the fly without any pre cooling. Are we "picking nits" here? (I did read page 93 of the PiP Manual)

    Re: Dianne Charging Only 1/2???


    Toyota told me (engineers) that if you need to come home and leave again by all means plug in, charge up, and go ev again for your next trip.

    They also said if you come home and know that you will not be leaving again, then wait and use the timer built into the car to set the charge to occur at night or even a few hours later. That way the battery has some time to cool down.

    Basically, if you can wait, wait. But if you cannot, it is not an OMG thing to come home and plug in to top off the charge if leaving again. I wouldn't say "picking nits" but accept it for what it is... When you can do it and wait, do it, when you can't don't worry.

    Deep discharge only happens when you force the charge-level beyond Toyota's automatic protection. Pretty much the only way to do that is to drive without any gas in the tank, intentionally disregarding the system warnings. In other words, you have nothing to worry about.

    Drive & Plug all you want. I certainly will be plugging in as soon as I get home if I know I'll be going back out again.

    Waiting is better, but by no means necessary. The system isn't that stressful on the pack anyway. The engine will kick in when tolerances are approached, just like they do now in extreme heat. It's not a big deal.

    Mark

    Thank you for your response. My four years of recent experience with EVs was with lead/acid battery packs. This will be my first Li Ion pack. My six years with a Prius have taught me that Toyota tries very hard to make the Prius as user friendly as possible for the average driver. That explains my use of the term "picking nit". Toyota does not expect us to treat this like a high strung European sports car. They basically expect us to drive the car. But we want to do the best for the car and its traction battery, of course. Not everyone reads the owner's manual and not all who do understand all of it. But there is a very lot of information, there.

    The trick is to do what us sensible, be regular about it and don't worry if I am following your thinking.

    Re: Dianne Charging Only 1/2???

    1) I wonder how Toyota prepares the new car's for their trip from the factory to the US. I can't imagine that they would need more than a 50% charge to drive them into and out of their place on the ship that bring them to our dealers.

    2) If and when Toyota gets back to you on your question about driving 62MPH, please do share the information with the rest of us somehow. I, too, would very much like to know the answer to that question.
