    Fisker Inc. dropped a video of its 2019 production vehicle, the Fisker EMotion, that gives us the closest look yet of the luxury electric vehicle. The EMotion promises a 400-mile electric range and a top speed of 161 mph. The company also claims the the car will charge for 100 miles in nine minutes...

    What a beautiful design... competition can only be good for consumers!

    With similar chemistry to the Hyundai Ioniq Electric, that charge rate is very doable.
    I thought Fisker promisted 125 miles in 9 minutes.

    Let's presume it has a big pack (400 miles), and similar consumption to Model S. So, around 300Wh/mi. It might have permanent magnet motors, after all? 133kWh needed.
    To charge 125mi (37.5kWh) in 9 minutes, would take (60/9) * 37.5 = 250Kw average charging over those 9 minutes.

    Ioniq pack: 28.0 kWh, 360V Lithium-Ion Polymer Battery
    It charges at a peak rte of 70kW. Let's take 68kW over 9 minutes to be safe.
    Extrapolate 28kWh to 133hWk -> 4.75x larger in capacity (not necessary weight or volume).
    4.75 * 68 = 323KW charging.

    So, easy peasy. Basically, Fisker is claiming to have SLOWER charging than the $32K Korean offers.
    And if the 400 mile claim is European, it would be less for EPA, so around 115kW and a proportionately lower required charge rate.
    Really, it's Tesla's turn now. Up the chemistry. We no longer *need* density, it's just nice for production costs so they can make even crazier margin on the battery part of the equation. To truly conquer the car market now, faster cells need to be used to make of the capacity. Chargers are coming (CCS 350kW, Tesla maybe faster?), so where are the Tesla packs to use that charge rate on? Current 100kWh cars are heavity throttled to 1.12C peak, whereas original S85's still get 1.44C.
    If Fisker were to use old school Tesla cells, they might actually get close to that 9min/125mi claim already. At present chemistry and further reduced by the larger 2170 form factor, Tesla itself will have much more difficulty...

    Fisher with old S85's cells: 133/81=164%
    117kW*1.64= 192KW. A good way near 250kW compared to Tesla's 115kW today.
    And if somehow the Fisher is 140kWh and actually only uses 280Wh/mi, it would charge those old 18650's in 9 minutes to 108 miles.

    The Hyundai Ioniq will either have terrible range degradation/batter failure or there is some serious voodoo magic at work. The charge rate this car has is insane. There must be a catch.

    Some of the more agressive power cells seem to actually deal with high cycles pretty well.

    Perhaps Hyundai just didn't put as much emphasis on cost/kWh, as they were going to need only 28kWh anyway to accomplish their range goals? They could also sacrifice some density this way, as there would likely be enough space for a 70-80kWh Tesla style pack, had they designed around that, Ioniq is not a tiny little car. If the 28kWh is relatively heavy or volumous...who cares? With faster charging chemistry and low consumption, this 28kWh car may well beat Model 3 on a road race past fast enough chargers within fair distance intervals. It consumes fewer electrons over say a 90 miles charger leap, and may well charge faster than the 3-60 will. We'll know soon enough!

    The important question is this - what is Fisker's funding and executive situation? Anyone know?
