Kia Presents Details On Soul EV Battery – Video

In one of the latest SAE Magazines video, there is a short presentation on the battery pack in the Kia Soul EV, which, in appearance reminds us of the Nissan LEAF battery pack.

Kia is using cells supplied by SK Innovation, with NCM cathodes and according to Steve Kosowski (National Manager, Long-Range Strategy/Product Planning, Kia Motors America) this type will soon be implemented in the Volt (of course, the manufacturer for Volt cells is LG Chem).

27 kWh lets Kia Soul EV get a 93-mile range score in the EPA cycle. This battery pack is also able to accept charge of up to 100 kW.

“Automotive Engineering magazine covers the 2015 Kia Soul EV traction battery. Steve Kosowski, National Manager, Long-Range Strategy/Product Planning, Kia Motors America, provides the details.”

Active or passive cooling? Maybe I missed it…

Its active, but whether liquid or air I don’t know:

Looking at then layout, presumably air.

Yeah, a heater and a churner fan.

Rather like saying my household blender is TOTALLY SOLID STATE, when it has a sole diode for its speed control.

I would think if it’s liquid cooled we would see some coolant lines/ports in the video.

The Kia Soul EV traction battery is air-cooled.

The car pulls cabin air from under the front seats through the battery case and exhausts it outside the car for cooling. There are also resistive heating elements for warmth.

Similar configuration to the i-MiEV (2012 SE/2014 ES) model. Interesting.

I assume passive. but its rather how to talk for 3 1/2 minutes and not say much. So I guess its just to feel good about the battery so potential customers don’t worry about paying double the price.

They have a couple of bits of info here, although nothing about the battery temperature management:

Nice info on energy density and specific energy at the pack level though, with the 274.5kg pack having 27kwh.

Its better than a Leaf or a Volt, but really getting the weight down is proving tough, way tougher than we had hoped.

Getting weight down is overrated. For example, 11% higher weight (300 lbs) in the i3 REx gives it 117 MPGe instead of 124 MPGe. Big deal.

Cost is what matters most by a mile, and after that comes longevity, pack volume, and mass. For the latter three, we don’t really need much more advancement than what Panasonic/Tesla already achieved.

I’d largely go along with that priority order, but it is also partly a case of not missing what we have never had.

Since we don’t have much higher specific energy batteries, we can’t design for them.
If we can hit something over 400Wh/kg than electric flight starts coming into view, for instance.

The other issue is that in practise cost seems to scale pretty well with energy density, judging by the comments the boss of LG Chem made on the battery in the Volt in this video:

That is not to say that other things like scale don’t count, but there is a strong correlation with energy density, and that is likely to get stronger as material costs form a greater part of total cost.

Around 4:30 in the above link, LG Chem:

‘From around 2010 to 2016 for the Volt battery cost will have halved, and energy density increased 40-50%’

That is pretty much scaling.

So much that BMW use carbon figer to get it down!
Much of it for the handling of the “ultimate driving machine” is true, but nevertheless controlling weight also have other important benefit than efficiency.

Too bad the Soul EV is so pokey in the 0 – 60. 🙁

And worst part is that the battery management system of the Soul is so mess up with the Chademo protocol, that it blew the controller of the first one they hook to in Québec.
The manufacturer of the fast charger fix it quicly and issued a ban to unable any Kia SoulEV to charge until they found a cure.
I can’t find any official link to it, but many EV enthusiast have been reported that to be.

So, you are saying that one of the biggest reasons to buy the Kia Soul EV – Fast Charge Ability- was a fail? Any feedback from any of the 14 new buyers on this?

We now have an Eaton L3 (Mitsubishi head office), a Nissan L3 (Nissan head office, near Mitsubishi) , and an ABB CJ53 L3 (PowerStream LDC at 400 & Major Mackenzie), in the greater Toronto Area, which would be easy for Kia Canada to do tests on with the CHAdeMO here in Ontario! BC also has some 10-12 CHAdeMO stations installed that they could test thus car on, as well. Plus, the 700 plus CHAdeMO stations installed Stateside!
