Maximizing battery life

    That's very interesting and is good information about how the battery was handled differently by two different manufacturers. I wouldn't touch a Leaf personally, and just read that their new 62kwh vehicle has a issue of some sort, rapidgate where it slows after getting hot or something?
    I wish they(Kia) would clarify if they do have a buffer below 0% and above 100%!

    There is definitely a buffer above 100%. This becomes obvious when you see that regen is still available even at 100% SOC. I've seen it go as high as 135 kw when pulling the left paddle while traveling at high speed. That regened power has to go somewhere. Most other EVs I've driven had zero regen until the battery level dropped slightly to make room for more charge in the battery.

    The size of the buffer is unknown but I'm guessing it's somewhere around 4-5%. The OBD2 sensors show 96.5% BMS SOC for 100% Displayed SOC.

    Still, why always charge to 100% if you don't actually need the range? I only drive 45 miles per day and my 100% range is 272. As a result, I typically only charge to 60%. This still leaves me with a large reserve in case I need to make any unexpected trips or can't charge for some reason.

    My use case is a little different. I'm trying to get by charging only once a week on the Niro, because my wife needs to charge our Volt nightly during the week for her commute, and we only have one level 2 EVSE. So, when I basically get 1 chance a week to charge, I gotta make it count! :)

    That makes sense. I could also drive all week on a single charge but luckily have a dedicated charger for the Niro that I can use each night. I guess there's always the included 120V adapter if you don't need to restore more than about 1.1 kw per hour of charge each night.

    TandM made another good point above in the other thread regarding the L2 charging rate. The fact that charging rate stays flat up to 100% without tapering like other cars, also suggests that there is a substantial buffer above 100%.

    Update- we have a 2019 Niro PHEV. We bought it in May 2019.

    We now have over 10,000 trouble free miles on the vehicle. If the vehicle is not on the road it is plugged in to charge. We use a L2 station in our garage (Clipper Creek unit). We have charged this in weather over 100 degrees with garage temps approaching 105 degrees. Have experience no problems or range issues. Now that winter is approaching we will be charging it no matter how cool it gets.

    That is why we got a Plug In and this routine allows us to maximize savings. Very pleased with this vehicle and its battery management system, battery and hybrid system.

    Incidentally I own electric Kobalt mower and weed eater. They both use modular Lithium batteries. I have 5 of these lithium batteries for the yard equipment (They came with the products). They are numbered so I can keep track of them We have owned these tools and batteries for 3 years. The equipment , batteries and chargers are stored in the garage. Last year I accidentally left two batteries on their chargers from November to April with the chargers plugged in. These batteries performed no different than the other three batteries this season.

    I wish Kia would bring the Niro into the midwest. In talking to local dealers, it sounds like there is no timeline to sell the car here. We gave up waiting and bought a Leaf Plus. Its a great car (I have driven long distances in the height of summer with fast charging without hitting rapid gate, but I know it still is out there), but Kia/Hyundai have a slightly nicer car for a very similar price point. I hope they can ramp up production soon.

    We also had trouble getting our Niro Plug In. Our local dealer told us no way this vehicle could be gotten in our area.

    I was not comfortable with the local dealer from the very start something was just not right with the way they approached us and treated us that made me uncomfortable. They did not listen to our needs and preferences.

    On an impulse I used Edmond's New Car buying service where you list the vehicle you want with options you want and Dealers who abide by the service rules bid on your business. A KIA Dealer 60 miles from us had the car we wanted and bid on our business and eventual won it with his low price and customer service. This service was free.

    I don't think I'll ever walk into a Dealer again after using this service, unless it is to test drive a vehicle. I was very pleased with the lack of hassle buying a car this way. With the different Dealers bidding against each other we got a great price.

    If you haven't done it yet you can go to the KIA website type in the vehicle you want and your zip code and it will show all the Niro's near you. We did receive a bid from a Dealer 500 miles away who offered to ship the car to our house for $350 if we wanted that vehicle.

    The Plug ins are a little hard to locate- I thought you might be interested in our experience obtaining one.

    We didn't want to wait either and so we started getting in touch with dealerships before they were released and picked our Niro EV up in April from a dealership in Maryland and then drove home to Ohio. There are now 4 of the Niro EVs in Central Ohio (and 2 Hyundai Kona) because we were all willing to make a drive to get them (though many of the other folks that have bought since us have had the advantage of looking over our Niro since we frequently take to the EV events and have even met up with a couple people privately so they could get their hands on and get comfortable before committing to a drive to get one).

    What about service?
    My local dealers told me flat out they won’t take the cars for any sort of service. Not even for non-ev items. That seemed like a potential problem point, especially if something incapacitated the car.

    Mine was in within the first 2 weeks of ownership for a replacement (under extended coverage) of the windshield (including calibration of the cameras which takes special equipment). They took care of it locally with no issues at all. I have since been in for the 7500 mile checkup and they took care of that easily as well. It will be returning to the garage later this week for the SA394 service bulletin and I expect smooth service for that as well. The techs at the local dealership had already been to the hybrid/PHEV/EV training before I purchased my Niro EV and already had serviced a couple Soul EVs (plus they dealership had sold a PHEV which they would be offering service for as well).
