Now the same data from the I oniq EV
The battery pack is much further back in the vehicle. This is probably because the roof is so much lower than the Soul. There is less space under the seats. I prefer the Soul EV layout, but the I oniq has the advantage of greatly reduced drag.
There's a great comment about the battery layout by anticitizen13.7 written in Jan 2016 on the TMC Forum
...the I ONIQ is first and foremost designed around a gas/electric hybrid powertrain. If you look at the detailed graphic of the unibody structure, the floorpan is Advanced High Strength Steel (AHSS) rated for over 60 Kgf. You can see the tunnel built for the exhaust pipe, which exists in the powertrain diagram. This is important because it almost certainly rules out the use of a skateboard battery platform in the pure EV version of the I ONIQ (deleting this floorpan to use a skateboard battery would have serious consequences for the rest of the body and chassis, basically requiring an entire re-design). This has several probable consequences for the BEV edition: worse weight distribution, higher center of gravity, and lower cargo space versus T esla, GM, and Nissan....

The I oniq EV has a battery by LG Chem.
It has 192 polymer pouch type cells laid out in a series string of 96 sets of 2 parallel cells.
The rated capacity of the pack is 78Ah Hence the rated capacity of each cell is 39Ah.
The total energy capacity is 31kWh ( What I have heard from people who have heard from LG, this has not been confirmed by a lab test.)
The I oniq EV battery pack is 31 kWh and weighs 271.8kg -> Gravimetric Energy Density = 114 Wh/kg
Edit: Originally I didn't believe the 271.8kg figure - but I've seen that number and the 260kg number frequently elsewhere.

The pure-electric version is much simpler, with a larger, 118bhp electric motor and a 28kWh, 260kg battery.
From - Hyundai I oniq review: A Prius beater from South Korea?
The battery cell used in the I oniq EV is probably LG Chem's LQ 1729-A2 43Ah Cell.
see: PDF datasheet for Lithium-Ion 43 Ah L3 LG Chem – LQ 1729-A2 Cell
192 cells * 43Ah * 3.75V = 30.96kWh which confirms that the total capacity of the I oniq EV is 31kWh.
The energy density of a single cell is 161.25 Wh / 0.966kg = 167Wh/kg
Hence it is probably not NMC622.
