SoulBox Range Extender project

Sun Feb 19, 2017 6:07 am

Hello all Soul EV owners
I'm Thomas, and I'm developer of PHEVBox Range Extender and LeafBox (and also solutions for Hybrid4 PSA systems).
I have prepared clone of LeafBox solution for Kia EV. More about LeafBox and whole concept here (KIa solution is just a fork of Leaf solution): http://vtechtuning.eu/leafbox.html

There is no magic in it - range extension in Leaf works perfect, basing on gliding add-on, better torque distribution, improved regen. I would like to check, if KIA EV gives same nice 10-15% range extension. I look for testers.

Installation is simple, results should come immediately. My problem is, that Kia EV is not in distribution in Poland, so I need some support.

PLZ help if you want.

Thomas

PS: Soon I will start FB page dedicated to Kia Soul EV project. Prototypes are ready.

I love your project because I think in fact that we can gain in efficiency, but I have a question: how to manage the passage in N mode on soul because it is a contact while on the leaf is purely software ?

(sorry for my google trad english)

Yes. I want to know more on that point too. How do you set regen level 0, so that you can emulate N- Neutral. And still be able to switch to the other regen levels. In this video you show regen level 0 is working, but not how you turn it on and off.

And yes I would be happy to help test this project.

In Leaf I emulated glide (N-mode) by controlling power demand level and "gravity" it to exact zero, if driver sets acc pedal in proper range (so LeafBox could find wish of the driver).
Same I have planned for Kia.

-
On the i Miev regen level 0 is called C mode or Coasting. I prefer this term to saying 'emulated N'

Am still not sure how L eafBox switches from coasting mode to another regen mode. For example coasting when coming down a hill onto a flat, before slowing down at the traffic lights by lifting the acc pedal and getting regen a few kms further down the road. Hopefully SoulBox will have the facility to swap regen modes.

I have solved that in following manner:
SoulBox observes behaviour of the driver, and tries to find, when driver seeks "zero power" position of throttle pedal. It learns automatically and after some time it can easily "gravity" torque demand to zero, even if driver is not especially precise (but it looks that driver wants to glide). While removing leg from throttle or accelerating torque/regen demand is similar to factory one, except more linear torque vs rpm (in Kia demand from throttle pedal is linearized to power demand, not torque - and this reduces efficiency (read idea here: http://vtechtuning.eu/leafbox.html, from Alternative accelerator pedal interpretation for efficiency

By the way, I have added a video, how LeafBox is installed in Nissan Leaf. For Kia Soul EV it is exactly same (5 minutes of work):

I did a long distance test witn box installed and programmed for Nissan Leaf (as I have no Kia Soul EV here to test it)
172,8 km, or 107,3 miles till turtle with 24kwh 2013 Leaf, 20,4 kWh available (Battery has SOH = 92,6%, a bit worn)
- winter tires, drive in hills (I have no flat terrain :( ) heat on but minimal possible, seat heating on (LO), ECO mode,
average speed of 62 km/h, I tried to drive not faster than 75, and not slower than 55 km/h
rural area, small cities and villages, maybe 5 stops because of lights, rather smooth drive.
Last 15 km done in higher mountains, as I wanted to be able to return home, so I drived high hill up and down till turtle (I know this is bad for range, but I have no alternative at all - at my home village there are no flat areas longer than 40 m...), and then - I returned home (luckily turtle came 200 m from home).
LeafBox range extender installed.

In 2 weeks I will install normal tires, so I expect improvement, even in our hills.

SoulBox is available for Norway, Denmark, Sweden and Finland via authorised partner - PureElectric

Also PHEVBox and LeafBox and soon - TeslaBox are available there.

I would be curious to test, but it is a little expensive and especially unavailable in france?
