Regen braking non adjustable ? Deal breaker for me.

[Doctors Do Little]

Wouldn't it be nice if regen bias was tunable through the app. Maybe just wish full thinking. Seems like a software issue.

I know! My golf cart has tunable regen via a direct connection from laptop but there are others that are Bluetooth via app…it’s just a controller setting, so seems completely doable?

It's possible that they'll enable it in the future. The truck may not be online, but you'll still update it via the app periodically. I'd imagine they'll allow you to turn it off altogether, but it'll otherwise default to 1PD.

I've never wanted to adjust the regen on any EV. Sometimes I want more regen, but never less. 1PD is one of the most underrated features of an EV.

 

[Daemoch]

The physical controller would have to allow it. Its added complexity to the physical circuit to allow for it. Pennies or dollars, no idea, but its added cost and complexity so not really their target.

 

[beatle]

It would really need to be some strange controller. You've been able to adjust regen and throttle curves on hobby level RC cars for decades. Even if the controller itself only holds one program at a time, the truck's computer could simply load the desired regen program.

I do think that cost has something to do with it though. They have to create and then test every regen program which costs money, even if the hardware is capable. They might only have on or off. Best to create the most aggressive regen profile to assist with efficiency. You can always use less regen by leaving your foot on the pedal a little further, but you can't add regen.

It does raise the question of how much it will be possible to introduce new features or changes into the vehicle's software, though I imagine Slate would have good reasons to discourage that.

Fortunately, almost any feature you add to the truck won't be integrated into that software.

Based on how Tesla has been updating their EVs with more and more regen and less coasting adjustments - Slate may fall into the same trap.

If Slate's 1PD is harsh and can't be adjusted between mild and harsh, I will pass.

My current EV was specifically chosen so that harsh regen is not chosen.

I prefer the old 2PD with regen and friction brakes combination.

Similar to when I taxi a plane, I prefer to have the friction brakes used on BOTH toes.

I was talking about third parties and users adding to or modifying the vehicle software. I would at least expect that, if Slate were to adjust things like regen, they would make it a setting rather than randomly changing how the vehicle drives over-the-air.

It would be weird if they did that, given their stated plans around hardware modding and documentation.

Curtis or Sevcon controller ?

Curtis or Sevcon controller ?

Neither. Denago (cheap Chinese knockoff), uses their own proprietary controller- thus the laptop via dealer.

I have adjustable regen on my Model Y. I really like regen braking, but In two years I have never felt the need to adjust it. So, if Slate can keep the price $300 to $500 lower w/o "adjustable" regen braking, I'm okay with that.

You must have an older MY ?
The new MY have non adjustable regen.

If Slate goes with Tesla's design, then I am out.

I love my Ford BEV with a choice of 1PD or 2PD.

I thought that what was being described by Slate was non-adjustable 1PD, as in, there will be 1PD and 2PD "modes", but 1PD wouldn't be "adjustable".

It would be weird if they only allowed 1PD, especially since the Slate seems to expect interest from many first-time EV buyers.

I'm still perplexed.

I scooped this up with my AI Slop Ladle:

Driver Preference and Control
Comfort and Control

• 1PD: Some drivers find it more enjoyable and easier to use, especially in stop-and-go traffic. It can lead to smoother driving experiences.
• 2PD: Offers more control for those who prefer to manage braking manually, especially in complex driving situations like steep hills.

Situational Use

• 1PD is often preferred in urban settings or when driving downhill, while 2PD may be favored in rural or highway driving where more control is desired.

Conclusion

Both driving modes have their advantages. The choice between 1PD and 2PD often comes down to personal preference and specific driving conditions.

Yeah, that is sloppy slop. It looks like jerky motion can be an issue, if the driver hasn't learned to keep their foot on the accelerator, and lift gently to slow gently. Taking your foot off means you want to stop relatively quickly.

I wish my 2022 Model 3 would work this way. Even if I lift off the accelerator quickly, regenerative braking takes a few seconds to ramp up to full.

No jerky surging here. But that's just me.
