    Hi All:

    The 2019 Kia Niro EV is in the garage and it is indeed all it is cracked up to be. ;)

    Connected for its first charge with my 40A MUSTART 240 L2 Charging Cable and it was accepting its rated 7.2 kW.​

    The first drive was back from the Press Fleet handler’s office in Gardena, CA back to Carlsbad, CA but first, how is it equipped?

    How did they deduce its 239-miles of AER from a 64-kWh pack? This should help describe it.

    Its EPA City and Highway range in miles are 259.0 and 213.6 miles respectively. Using the EPAs 55/45 percent city/highway split, you have (259.0*.55) + (213.6*.45) = 238.6 or 239 miles. The city and highway range numbers had to be pulled from the 2019 EPA data files.

    It is definitely easier to achieve higher efficiency in a city/suburban environment than an all-highway one in my three days of driving it.

    What I do not know is how the 30-miles/100 kWh is deduced. The data files did not indicate the 64-kWh pack was usable or max. The Total V (356) and Ah (180) ratings indicate a maximum 64.080 kWh. How much is usable would be a guess at this point. Maybe 60 kWh? With a usable 60 kWh and 30 kWh/100 miles (3.33 miles/kWh) rating, that only yields 199.8-miles of AER. Even if the entire 64 kWh was usable, that would only yield 213 miles of AER which happens to be the highway rating. I am just not sure but if you have any input on this, by all means, let me know.

    I was watching a youtube video within the last week or two that had some British car guys driving a group of EVs until they died to measure real world electric range.
    The Niro came in second place behind the Model 3, and offered 90% of its rated range while other EVs were closer to 2/3 of their rated range.

    It will be interesting to see what the Niro offers in the hands of someone who doesn't beat it to death in the name of "real world driving".

    Hi Chris:

    Here are the results of the first drive of the 2019 Kia Niro EV on the 405/5 between LA (Gardena, CA) and Carlsbad, CA during rush hour which is always a mess. :( I have more questions than answers unfortunately.

    2019 Kia Niro EV First Drive

    [​IMG]
    Displays reset with 273-miles of AER indicated. The Garmin showed ~ 50' ASL.​

    The Drive info included somebody moving the Niro EV around the Fleet offices after charging apparently. It resets each day. Over what specified number of hours, I do not know?

    2019 Kia Niro EV First Drive Results

    [​IMG]
    [​IMG]
    217-miles of AER available. 99 percent Driving Style - 5.8 mile/kWh over 81.3 miles indicated, 83.1 miles actual in 1 hr. 47 min. for a 46.6 mph avg speed.​

    The Estimated AER is based on the previous charges result so that display is kind of FUBAR. I have seen as high as 299 between charges after my drives... In any case, a loss of 56-miles of range after 83.1 miles is not too bad. If the Niro has 239-miles of actual range at 3.3 kWh, the 5.8 mi/kWh should provide about 420-miles from fully charged to dead on the side of the road. That is not a bad result but how do we get there if only 64 kWh is available??? 64 kWh * 5.8 miles/kWh = 352 miles. In other words, I have no idea how some of the results were derived. And since this first drive was not my topoff - if it was topped off? -- I only plugged it in to top it off for another calibration drive.

    During that first charge, I saw 7.6 kW charging in the diver’s display. It only has a 7.2 kW L2 Onboard charger so a few more ???'s. If you look closely, the SoC indicates 81 percent so I consumed 19 percent of the pack to travel 83.1 miles? I bet I consumed more than that as this would indicate ~ 437-miles before the pack is as flat as a pancake. I do not think I will complete Top off to almost empty drive but I should just to find out. ;)

    Hi All:

    Yesterday morning, I went out for a lengthy RT drive almost to San Diego and back with CC set at 55 mph through the construction zones and 70 mph - 5-over the PSL - for the rest of the drive. The occasional traffic slowups on RCC and maybe 10-miles of city/suburban from my home to the I5, a few miles of city north of SD to turn around, and back again to my home rounded it all out.

    2019 Kia Niro EV 2nd drive

    [​IMG]
    RCC set at the PSLs out and back - 3.6 miles/kWh over 74.1 miles with a 47.2 mph avg speed.​

    This is probably more indicative of an average driver and 3.6 miles/kWh still breaks its EPA.

    Charging after the second drive I saw this in the Niro's EV menus.

    2019 Kia Niro EV Charging Rate Selection(s)

    [​IMG]

    I had already started charging the Niro at 7.2 kW when I booted up the car to see if I could switch the rates on the fly during a charging session? I could not. No matter if I selected maximum which it was set to before I found this menu it charged at 7.2 kW. When switching to the mid or slow rate selection, the Niro EV continued to charge at the prescribed 7.2 kW rate per the MUSTART display. I suspect that before a charging session has been initiated, an owner would be able to select the rate they would like and the charger would communicate with the J1772 box on the charging cable and program it for a lower rate. Max is 7.2 KW so I would guess that the charging rate could be reduced to 6.6 KW and 3.3 KW? I completed a short calibration run with Marian to the Movie theater to see Ford vs Ferrari and back which I will post next.

    Tonight, after the steady states, I will select the Niro EVs "Reduced" charge selection, plug it in and record what the MUSTART is displaying. Remember the Prius PHEV displayed 2.2 kW on the MUSTART 40A cable which was its max charging capability on a L2. After that, I will disconnect, setup for the "Minimum" charge rate, and see what the MUSTART 40A display indicates after that as well?

    Hi All:

    With the MUSTART 40A Charging Cable able to measure to the thousandth of a kWh and our Garmin accurate to a tenth of a mile, we really do not need to calibrate an aFCD - in this case, an aECD - over 50 to thousands of miles. I call that a win for everybody! Especially me as fuel to topoff from wherever the Press Fleet handlers refueled to which is usually $10 to $25 less than topped off, re-topoff at $10 to $50, and again refuel for the long drive back to the Press Fleet handlers if necessary is not free by any stretch. Neither is the electricity either but I digress. :)

    2019 Kia Niro EV - Calibration Drive

    [​IMG]
    Reset to 6.1 miles/kWh over 12.1 miles indicated, 12.7 miles actual.

    [​IMG]
    Reset to 2.061 kWh with the NIro's battery from 98% to Full SoC.​

    12.7 miles on 2.061 kWh = 6.16 miles/kWh or a positive 0.9 percent aECD offset! Oh how I love positive aFCD and aECD offsets!!! :)

    Hi All:

    Like all EVs and PHEVs, when they are close to fully charged, they do not maintain their max charging rate and fall off significantly the closer they come to full. Some EVs charge at just half their initial rated charger kW at 50 percent SoC and the closer to full, they drop off into agonizingly long waits in fact. I am speaking about High Speed L3 DC charging here, not L2 however. There was a minor falloff but the Niro did not fall off like I would have initially expected on a L2 as indicted below.

    2019 Kia Niro EV Charging Rate at 98% SoC

    [​IMG]
    In this case, the initial charging rate is 5.2 kW at 227V and 23.2 amps.​

    Hi All:

    As you can probably tell, this MUSTART 40A Charging Cable, control and display is "Da Bomb" for this kind of thing!!!

    I would have to manually record the rate and SoC at 10-minute intervals to come up with a smooth curve on the fall off for the Niro while on an L2 but from the indications, the falloff is almost non-existent until ~ 99 percent SoC.

    Hi All:

    It is just after 02:00 AM local and I am sure many of you have heard the song by Albert Hammond called "It Never Rains in California" ...


    That is unless you are going to complete steady states. :(

    Maybe tomorrow night.

    I like this Kia DeNiro. It's a correctly-sized station wagon.

    Too bad they don't sell it here.

    Altho EVs can reduce energy consumption, leadfoot drivers are proving that EVs can waste as much resources as ICE, & quickly destroy EV battery packs.

    If I were coked-up inked-up droopy-haired kook writing for one of those car-fan outlets, I would need to know that my EV could complete the quarter mile in under 13 seconds because that's the minimum performance metric for safely merging onto a freeway that has all lanes completely stopped for an average of 21 hours a day.

    I can't say I blame them for quoting horsepower - which is a useless calculation of torque over time that has no direct relationship with how fast a car actually accelerates, or quoting quarter mile times - which is useless because it depends on temperature, tire pressure, pavement composition, and ultimately is meaningless because a quarter second improvement is undetectable to drivers and passengers. They need to do this to stir up emotion and sell advertising. While most brilliant drivers will look for the detailed content of engineering journals, that level of technical content doesn't sell to viewers who want to know that "horsepower is up this year to 208!!!"
    Witness how many youtube videos featuring the Tesla are there to show Ludicrous mode and not the ordinary everyday commuting the cars are built to provide.

    Hi All:

    The 2019 Kia Niro EV has not been crash tested by either the National Highway Traffic and Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS).

    NHTSA has only tested the Hybrid with a 4 of 5-star rating including concerns about front passenger side safety.

    2019 Kia Niro HEV, PHEV and EV NHTSA Crash Test Ratings

    [​IMG]

    Moving to the IIHS, they have tested both the Hybrid (HEV) and Plug-in Hybrid (PHEV) but not the EV.

    It has earned a Top Safety Pick+ rating, the IIHS' highest score across the entire gambit of crash tests with only the headlamps being rated Good or Poor depending on trim.

    [​IMG]

    2018 Kia Niro PHEV-26 IIHS Small Overlap Crash Test


    While the HEV and PHEV is not the Electric, we may be able to infer some crash test safety similarities. Just not the actual crash test safety ratings.

    Finally, with the release of the 2020 Kia Niro EV at any time, it should not be to long before we will see the Kia Niro Electric crash tested by at least one of the two U.S. crash test safety bodies. When I see one or both, I will update this review with them here.

    Hi All:

    I completed the Steady States tonight and they were pretty rock solid. 50 though 70 mph on the CC setting, speedo, and Garmin matched up dead on from the bottom all the way to the top.

    Our first steady states data collection with an all-electric!​

    I will generate the graph tomorrow as I have to change the y values to miles/kWh and the formatted range. I also still have to figure out what EPA highway is as that is a figure not provided anywhere that I can find.

    Hi All:

    The reduced Amp charging configuration does not appear to do anything? Maybe slightly less charging current but 31A and 7.2 kW is what I have been seeing under the maximum setting? I just checked after 25-minutes and it is running still charging at 7.2 kW and 7.4 kW still showing up on the Niro EVs display vs 7.6 kW like it was at maximum?

    [​IMG]

    Tomorrow sometime I will go for another drive and come home with it set for the minimum and see what changes if anything?

    Hi Bill:

    I have the MPGe from the Monroney and the EPA. I was looking the highway number as a mile/kWh result. Those fields were left blank for the 2019 Niro Electric within the EPA data files.

    I will probably use the EPA combined 100-miles per 30 kWh rating - 3.33 miles/kWh, and work off the MPGe city/highway at 55/45 percent to deduce the EPA city and highway results in miles/kWh.

    Can you just use the 33.7 kWh/gal multiplier that the EPA uses? So 3 miles/kWh would be 3*33.7 = 101 MPGe. (102 miles/gallon) / (33.7 kWh/gallon) = 3.03 miles/kWh

    edit: added check. 3.33 miles/kWh * 33.7 kWh/gallon = 112 miles/gallon (e)

    edit2: here are the 3 numbers you needed in miles/kWh:

    city 123/33.7=3.65
    highway 102/33.7=3.03
    combined 112/33.7=3.32

    Hi Bill:

    Excellent and you did the work for me!!!

    PS: The 2019 Kia Niro Electric beat its EPA highway of 3.03 miles/kWh at 70 mph. ;)

    Hi All:

    With temps from 49 to 51 degrees and calm winds for the NB and SB runs, the 2019 Kia Niro EV Speed vs Energy Efficiency curve looks like this...

    [​IMG]

    The EPA highway rating of 3.03 miles/kWh was deduced from Bill Lin's 2 posts above. Worked like a charm. :)

    The EPA Highway efficiency rating speed crossover on a straight line estimate occurred at 73.0 mph indicating the 2019 Kia Niro EV is a bit more efficient than its 3.03 miles/kWh would indicate. I have found it is more efficient than its 3.65 miles/kWh rating around town as well.

    Hi All:

    Marian and I went to Costco for a Grocery run. $175 for our church and $220 for us. We needed much of the 2019 Kia Niro EVs 53.3 cu. ft. of cargo volume to bring all $395 of it home.
