TeslaChip - Tesla Model S, Model X and Model 3 - range extender and easy coasting
Code: 5108/S- 5108/3 Choose variantProduct detailed description
TeslaChip 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 Tesla Model S or Tesla Model X:
- 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% (for all sizes of batteries). It does not affect maximum power, but it alters torque distribution along.
- the regenerative force at D mode comes faster. Removing leg from accelerator pedal gives more rapid invoking of regeneration.
- Smooth power delivery promotes battery health. Optionally maximum power can be limited to prolong battery life and health (for usage as taxi car or car for hire)
What can I expect from TeslaChip?
Basically, all these solutions are range extenders basing on lower battery current flows (for both directions: drain or charge) and lower energy usage.
- - it promotes more accurate drive with enhanced pedal precision for low loads
- it protects the battery from unwanted rapid burst discharge, by creating "kick down" behaviour only at the end of pedal position.
- it reduces battery wear by adding coast/glide functionality. EV car without box drains or charges this battery, but it is almost impossible to coast with zero energy usage. As battery efficiency and motor efficiency are not 100%, continuous energy flows cause thermal loss of energy. TeslaChip improves car behaviour and thanks of about 20% lower energy flow - it reduces battery temperature and prolongs its life!
It is especially important in Nissan Leaf (both 2012-2016 versions and new 40kWh versions) as Leaf hasn't thermal management of battery, but of course, it reduces energy usage and battery stress in Tesla too.
Simple like hell: less bi-directional energy flow = less energy converted to temperature = lower temperature of battery = longer battery life. Period.
Alternative accelerator pedal interpretation for efficiency
Until now all Tesla models except P versions (performance versions) have simple “accelerator pedal (acc) position → power” transition. A position of the accelerator pedal is converted to power demand immediately and almost linearly. This we can see at energy usage panel in the car, and we have verified that also with our laboratory chassis dynos (http://vtechdyno.eu).
This method of power demand control suffers from two negative effects:
- Acceleration of the car is not stable at all. The car first speeds up better, then, falls down with acceleration – as acceleration simply depends 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).
- We have scanned Tesla powertrain for efficiency (by comparing power taken from battery vs propulsive power at dynamometer and some parts of 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:
We have prepared an alternative power demand curve (presented as the bold line in the small graph vs. thin line with same colour – factory) that promotes two things: more constant acceleration and more efficiency.
More constant acceleration for a moderate drive is, in my humble opinion, something perfect for Tesla. 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 for more time in the optimal efficiency area – this is a “side effect”, as we have “constant torque” strategy instead of “constant power” strategy. I cannot directly say whether or not this will extend the range (or maybe a bit) but it should at least give positive effects on a range.
For acc pedal levels over 70% torque demand curve becomes increasingly „constant power” type. For 100% pedal, it is just factory 100% power line, not altered.
Below 20% 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 crossroads.
TeslaChip includes feature of N-mode on demand. While driving in D-mode you can almost remove the leg from acc pedal. TeslaChip will set motor power to zero (0 kWh) so you will roll without energy conversions. This increases efficiency with long distance trips and is good for overall range (autonomy).
TeslaChip – FAQ
- Do you ship to USA?
No, we do not. - Can it be detected by the dealer/car manufacturer?
No. There is no risk for warranty as it is undetectable. - What modelyears and versions of Tesla is TeslaChip compatible?
All. - Is that difficult to install TeslaChip?
No. You can do that within few minutes, without any car modification. Box uses factory plugs. - Is power increase safe for my Tesla?
Power increase is optional and bases on limits provided by manufacturer. Thus - TeslaChip does not demand more power, than maximum permitted by manufacturer. - 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 TeslaChip is good for battery life. - Is the range increased?
Yes. You will observe up to 10% better range while moderate driving – of course results can be even better when you will use coasting mode more. This is caused by more sophisticated and precise electric power applying, and gliding (N-mode on demand) functionality. Battery is not drained to lower level, than factory designed. - Is that legal to use TeslaChip?
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 TeslaChip?
In additional to your Statutory Warranty (2 years) we offer a 14 Day Money Back Guarantee. If for any reason you are unsatisfied with TeslaChip, 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 TeslaChip
