Kia Soul EVchip - range extender and regenerative force improvement
Code: SOULBOXProduct detailed description
SoulChip is a range extender controlling load applied to engine via throttle control. No problems with warranty - undetectable by dealer. It is easy to install, as it uses factory plugs. It delivers following extensions to standard Kia Soul EV:
- range extender – it bases on adding „N-mode on demand” (aka glide mode) to D-mode, along with alternative torque delivery strategy (read below). Range extension is around 10% (ECO mode). With normal mode SoulChip is off.
- regenerative force at D mode can be increased by about 20%.
Alternative accelerator pedal interpretation for efficiency
Until now all Souls have simple “accelerator pedal (acc) position → power” transition. Position of accelerator pedal is converted to power demand immediately. This we can see at energy usage panel in the car, but I have verified that also with chassis dyno.
This method suffers from two negative effects:
- Acceleration of the car is not stable at all. The car first accelerates better, then, falls down with acceleration – as acceleration is simply dependent on torque, and because car has almost constant power for any rpm and any desired acc pedal position – it is logical that torque MUST go down (see graph – thin lines in the big graph – torque of car (=acceleration) for various acc pedal positions (verified with dyno).
- Some parts of our acceleration are not crossing optimal motor efficiency (red and orange areas). In some areas it is impossible, but of course everything can be optimized.
Conclusion:
I have prepared an alternative power demand curve (presented as bold line in the small graph vs. thin line with same color – factory) that promotes two things: more constant acceleration and more efficiency.
Constant acceleration is, in my humble opinion, something perfect for our Souls. I understand that it is hard to describe, but all SoulChip samples I will start to send soon to testers will have this new characteristics added (and with option to switch it off back to factory type of power demand – so they can be easily compared). I have been driving for few days with this setup – it is so nice that now, when I press the pedal to some position – acceleration is much more stable. There is no rapid power demand, and power demand changes in time (as the power is now not constant, but rather torque is more constant). This is visible on the power usage panel.
Remaining more in the optimal efficiency area – this is more or less a “side effect”, as we have “constant torque” strategy instead of “constant power” strategy. I cannot directly say whether this will extend the range or not (or maybe a bit) because I haven’t tried this on my test route.
For acc pedal levels over 70% torque demand curve becomes more and more „constant power” type. For 100% pedal it is just factory 100% power line, not altered.
Below 30% of acc pedal I have used less flat torque curves (not shown on the graph) because of the need for a jump start at lights or cross-roads.
Soulchip feature of N-mode on demand. While driving in D-mode you can almost remove leg from acc pedal. SoulChip will set motor power to exactly zero (0 kWh) so you will be rolling without energy conversions. This increases efficiency with longer distance trips and is good for overall range (autonomy). Power gauge is visible on right side.
SoulChip – FAQ
- Do you ship to USA?
Yes, we ship to USA. - What modelyears and versions of Kia Soul EV is SoulChip compatible?
All. - Can it be detected by the dealer/car manufacturer?
No. There is no risk for warranty as it is undetectable. - Is that difficult to install SoulChip?
No. You can do that within few minutes, without any car modification. Box uses factory plugs. - Is there any risk for battery?
No. Battery works with same maximum current as designed by factory. In fact, smoother power control and low speed reduced energy drain in ECO mode helps battery to be more durable (and thus - increases range). Using SoulChip is good for battery life. - Is the range increased?
Yes. You will observe up to 10% better range in ECO mode. This is caused by more sophisticated and precise electric power applying, and gliding (N-mode on demand) functionality + slightly increased regen in D-mode. Battery is not drained to lower level, than factory designed. - Is that legal to use SoulChip?
As there are no car permanent modifications, modifications of power, emissions, safety – there are no reasons for such solutions to be illegal (like for car alarms or other additional equipment). - Can I return SoulChip?
In additional to your Statutory Warranty (2 years) we offer a 14 Day Money Back Guarantee. If for any reason you are unsatisfied with SoulChip, please contact us within 14 days of taking delivery, and organise to return the product and receive a refund. Product must be undamaged. - I have another question concerning SoulChip
