It's great to hear from the lead engineer, thanks for joining the conversation!
1. @GetOffYourGas; LED.
- I understand your frustration with the LEDs location. It was designed to indicate diagnostic parameters and not part of the UI/UX. Can you please explain how you'd use it besides the initial setup?
- We are transitioning over to a new LED part which is more efficient (*2 mcd) and we also lowered the current limiters to increase visibility. Not sure though it addresses your difficulties. We are deliberately trying to stay away from external input (buttons) / output (displays) devices to decrease complexity.
- Reading an earlier post on audio feedback; pretty intriguing idea. I've ordered 3 different low-current piezzo buzzers, one SMD and 2 externals for R&D. Will keep you updated, although one of the first things I do on my cars is "nuking" the buzzers...
If I were to purchase this device, I suspect that I would want to change the modes periodically, based on my needs/ desires. If I want to have some fun and don't need the range, a less aggressive mode will do nicely. If I am going on a longer trip with limited charging options, a more aggressive mode would be preferable. Whenever I change modes, it would be nice to have an easy confirmation of the current mode without climbing into the wheel well. That would get old fast, and discourage me from taking full advantage of the modes you offer.
2. @GetOffYourGas; "The lag and acceleration"
- You are right, in its most aggressive mode, the timing effects (it is not a traditional lag filter, rather an optimized dynamic approximation curve - ODAC) can be felt. We have addressed that with a 2 stage ODAC which kicks in based on input evaluations. It sounds like the 2nd stage did not kick in in your case. I went back, replayed the possible scenario you are likely to have experienced in our lab and adjusted the parameter evaluator. The 2nd stage blending function should activate more responsively now, although it may come at the expense of energy efficiency. It is not an easy task to strike the right balance between performance and efficiency, and without going into details, our system constantly analyzes the I/O pmeters and makes small modifications (one may say it tries to learn).
Thanks for the info. I understand that performance and efficiency are competing requirements. Does the delay help efficiency? I'm sure the slow ramp-up of power does.
As I'm driving more with the device, I'm getting used to it. Like I said, the issue is more the sudden unexpected change in response time. If/when you do sell these to the general public, I would make sure that is explained in your literature.
