    Has anyone used a public charging station in combination with the charge schedule feature on the Prime?

    My office has more (free) EV chargers than people right now, so sitting on the charger isn't a problem, but .. do most public chargers end the session if there's no current draw after a while, or will they stay active until you unplug?

    I'm trying to keep the battery from full as much as possible to extend its life, in as much as that's possible.

    Toyota already practices battery management with the Prime.
    IIRC when your car is "full" your battery won't be.
    It's a warranty thing.
    Toyota Prius models released before 2020 get a warranty battery coverage of 10 years or 150,000 miles in states that have adopted California emission laws, and 8 years or 100,000 miles in states that follow federal standards.

    As far as Charging Edicate (Etiquette?) that's a developing thing, but always remember that you have 2 fuel sources, and BEVs only have one.

    The Golden Rule would seem to apply......

    is it public or private? if public, what system is it? if private (company installed and operated) and works just like home, no problem scheduling. if you have to use a cc, it may be a problem, depending on the sytem.
    edicate only comes into play when demand exceeds supply

    Private but listed on chargepoint . most of the ones pictured are free.

    I understand 100% and 0% aren't the technical limitations of the battery, I had just read that it's less cycles on the battery (and most stable battery chemistry) when it's not at 100% (displayer) all the time. Hence the desire to defer charging until close to when I went to use it

    I charge to full daily. We installed a level 2 charger (juicebox) at the house last month for a Tesla, so I have been using that on the Prime. It charges in around 2.5 hours. We have 179k miles. I think the car can handle it. I'll let you know. We drive 50k miles per year, so we are a decent data point.

    Most public chargers deactivate when the vehicles voltage request drops below a threshold. So it's unlikely you can use a timer.

    As @ETC(SS), already said. Full doesn't mean full on a Prime. I'm not savy on what full is on a Prime but on my old Pip full was 85% SoC. I just charged to full at work and didn't worry about it being like that all day. In fact, I volunteer to drive on the few occasions we go to lunch so I can use that free juice.

    I have done that hundreds of times. When there are 8 chargers and only 3 plug-in vehicles, you can sit there all day without issue. No problem. The scheduled start works fine.

    The session will not end automatically. You have to release the handle to stop communication.

    I have seen the opposite. Think about approach. Billing based on time is very common. You stay longer, you pay more. Deactivate would not support that.

    I don't disagree with you. OP can only try and see what happens.

    And therein lies the rub! One of our haunts (shopping area) has two public chargers and, invariably, the same two BEVs, will be parked there sucking juice for an extended period of time, precluding use by anyone else.

    Etiquette (common decency) should include NOT hogging public chargers on a regular basis in lieu of charging at home!

    Hmmm..maybe plastering one of those impossible to remove stickers on the perp's windshield each day?

    Hi satsuke, my company provided EV charging stations from ChargePoint for employee use. In my experience, if the car didn’t start to charge within a few minutes of session start, the station reports an error and cuts off the current. So using the charge schedule function wouldn’t be useful for timing when the session starts on ChargePoint.

    As to the reason to do this to optimize battery life, I just charge to full at work in the morning then drain it on the 50 mile evening commute home. Recharge to full again at home. Minimizing the time the battery sits at “full” by completing the charge just before driving should not make a difference.

    I think you can do the math and limit the charging current so that it charge slowly and takes longer time.

    Why not just pour some of the gas out of your tank and torch the car while you're at it?
    Some BEV drivers don't just want to scarf up 25 "free miles" but rather they use chargers as their sole source of fuel, and it seems to me that if they get to a public charger first, then they get to it first.
    I hear a LOT more anger from the EVangelists in the room who are effectively ICE'd out of a charger by somebody with a 'compliance' vehicle leaving their car not-charging, but plugged in at a public charger long after their their batteries are topped off.

    I remember a few years ago, some PHEV drivers thought it was their birthright to plug their cars in wherever they found an unguarded outlet. Now there are going to be charger wars....

    I'm glad I can pay my own way for a while longer while they figure all of this weighty stuff out.
    One thing I like about the 2 Tesla chargers in this part of the country is that they put them in an out-of-the-way place in the parking lot, so at least gassers aren't tempted to park there just because they want a good spot near the front door.

    Fwiw, it appears the behavior is that the charger keeps communications open, so the car "sees" charging is available, but it isn't actually there to be called on.
