It's gotten cold here and regen is basically never on. I can't believe I have to just guess how hard I'm going to brake with one pedal driving based on how cold it is. You'd think there would be a system to heat the batteries powered by Regen braking if it's cold. Or apply the brakes automatically to make it feels the same as it normally does. Honestly, shocked that this is what they went with. Everything else has been amazing.
I should be taking ownership of my Tesla soon and was wondering what to do at long lights. Do you apply the brake petal or not? My thought is, Tesla doesn’t creep and the regenerative braking is being applied so you can just sit their giving your feet a break.
My understanding is that combustion cars have brakes that turn the car's kinetic energy into heat energy, and electric cars have both these conventional brakes and can also do regenerative braking that turns some of the car's kinetic energy into electricity instead of heat. The reason they have both is that regenerative brakes can't apply nearly as much braking force as normal brakes. My question is, would it be possible for regenerative braking to be engineered to be capable of stopping a car just as quickly/effectively as conventional friction brakes can?
Is it normal for MY not to accelerate when regenerative braking is reduced? I mean, when I press the pedal to the floor, the car does not accelerate at all. It will slowly go from 10, 15, 20, and on, even with the pedal pressed down. Not ideal for highway driving. I am just wondering if this is normal since I have never seen this behavior before. I have owned the car since October 2020 and was bought brand new from Tesla.
as a precaution, I always tap my actual brakes when coming up to a stop sign or construction zone, etc. if someone seems too close because I’ve never learned if they come on when the car is using regenerative braking. Is there any indication to the person behind me that I’m slowing down?
I am working on a new pedal box for our team and I am finding it difficult to decide what is the best way to read the pilot's input for regen braking (we are looking towards some signal that is read before the mechanical brakes are applied, to improve regeneration). I see that some teams use:
1. a load cell on the face of the pedal with a gas spring holding the pedal still until a certain force is applied;
2. a pedal travel sensor (in this case I think we would need to make some kind of mechanism to create a "dead zone" on the pedal so that the mechanical brakes are just applied after some travel);
3. a "throttle off" concept, where regen starts actuating when the throttle pedal is released (I've seen some people saying it is not good for vehicle stability, especially in curves).
What do you guys use or recommend?
Title, working on a club project and I was wondering if someone who knows their stuff would be able to further understand this concept. I've read around the internet but a lot of it is surface level and never specific enough. Thanks in advance!
In an ICE car, one cruises without applying brakes and the speed naturally slows down without braking. Tesla can do the same depending on the driving mode settings.
So when and how does the regenerative braking determine to illuminate the rear brake lights?
I always drive "B" mode. I've always wondered, when I press the brakes lightly is it actually the brake pads physically touching the rotors or does that only happen when I press harder or when I'm going slower? Is the extra slow down I feel when I press the brakes from the brake pads or is it more resistance from the motor? I know the brake pads will eventually have to come into contact with the rotors but when exactly does that happen?
Hey electroboom, I was just wondering about Eddy Brakes And weather they can be used for an electric car and weather we can use the energy generated by the brakes to power the car battery so we will save a lot of energy what do you think? Will it be FREE ENERGY?? :p
Hey there,
I can't seem to find a valid source or not. Does regenerative braking use the brakes at all when set to the max? Is it like the "e pedal" on the nissan leaf where it does use the brakes, or is it just significantly increased? Main reason asking is to lower amount of brake dust for my fancy pants wheels to keep them extra fancy.
Thanks,
When my wife pulls her foot off the accelerator, her car slows down aggressively which is great and by design. Her tail lights do not turn on. So I'm wondering if I should be looking for a blown fuse. Or maybe the tail lights are not supposed to turn on. The sales guy at the dealership said the tail lights are supposed to illuminate when coast-braking.
Why regenerative brakes cannot stop the car to a complete halt?
Is it software that switches to brakes for better driver control? Or it's the physics on how electric motors work and it's not enough energy to charge batteries at low speeds?
Adding dummy characters to meet the minimum character requirements to post it on the subreddit
Just realized this today. I've been mostly using the left steering wheel paddle for braking since I got the car in order to maximize regen, but I haven't been very happy with the arrangement because it's rather unpredictable -- sometimes slows the car down reasonably quickly, other times it's extremely gradual. Now I've noticed that the brake pedal is a much better option, since it will also recover energy for the battery but allows for control over the rate of deceleration. Presumably pressing hard on the pedal will engage actual brake calipers for friction braking.
Did everyone else already know this? Is this a standard EV thing? It was quite a surprise when I realized what was going on.
Hey I was curious if abusing the regenerative braking to get higher gas milage would wear down your brakes quicker?
I'm wondering if there are any negatives to doing this. Once I train myself on how soon to let up on the throttle before stops, it seems like the best mode for battery range.
After further examination, my analysis of the problem in this thread is actually wrong entirely. The bluetooth adapter detected the presence of the scooter well enough to disconnect the device from Mi Home and add it again. Therefore I feel that it's unlikely that my device's connection to the scooter has anything to do with the acceleration of the vehicle; the problem appears to be with the regenerative brake that is supposed to kick in when the acceleration button is let go.
The issue I'm experiencing is that instead of working as intended, the regenerative breaks "flicker" rapidly as the accelerator is pressed, regardless of how the button is pressed (whether it be held, pumped, or simply let go). This means that even though the accelerator attempts to work properly, it cannot do so since the regenerative brake keeps activating and de-activating rapidly, hence my description of the device "flickering". I suspect the problem has in part to do with the fact that the unit fell onto its side about a half hour earlier, so I'm not exactly sure if it's an error with the software or if it's damage to the hardware that's causing this issue.
If anybody knows about the inner workings of the Xiaomi m365 and would like to provide help on what parts to check and advice on how to see if they're broken or not, I'd appreciate any help of this sort. If I can identify a broken part, there's a good chance I can get it replaced and (hopefully) fix the scooter in the process.
I get how the motors act as alternators, but don't quite understand how pushing the brake harder stops the car faster and creates more electricity. I'm guessing there's no clutch or movement of the motor coils, and that the drive motors are the generators? Thanks in advance!
I’ve been scouring the manual and have found nothing, and google isn’t much help. I found one review that says brake lights definitely come on during regenerative braking, but it doesn’t say if it’s for all levels. Brake lights seem necessary for Level 3’s speedy deceleration, but not necessary for Level 1.
Do the brake lights come on every time I take my foot off the gas, regardless of level? Anyone know for sure the answer? Otherwise I’ll need to beg someone to drive behind me and let me know.
Not sure if this is real or imagine on my part, but I'd like to get other Gen 2 owners' opinions.
So I love my gen 2 Volt, when I've had for 3+ years now, but it feels like the regenerative brake paddles behind the steering wheel does not slow the car down as much as during the first year, when I could basically just use it along with the cruise control (meaning no foot pedals required) when I drive on the highways. My driving style hasn't changed, but now it seems like I need to use my foot brakes a lot more often. Has anyone else noticed this?
This is to prevent overcharging the batteries. Not sure of the exact percentage. This happened to me after getting my Model 3 delivered at 100% charge.
Hi r/volt! Just purchased a used 2015 volt with 47k miles. Still learning the car and the sounds it makes. Whenever the regenerative brakes are engaged or disengaged (I.e. when the battery is starts getting charged or starts using energy) I hear a audible clicking or knocking sound. Doesn’t happen in neutral or while accelerating or braking for a while—only at the moment energy flow switches direction. Not sure if this is a normal noise or something common. Any advice?
Edit: Update for the sake of any future people searching for the same problem! I did as the many comments suggested and tightening my front two axle nuts to 185ft-lbs (they were under tightened) and the knocking sound has gone away. Thanks for the help!
After getting non original pro display on non pro M365 and flash with custom firmware 1.5.5 with KERS off. Doesn't have this issue if KERS is on.
Update: Issue has been solved with newest CFW
I know this is old news, but I forgot about this and hurt myself. I'm posting to remind everyone that on a full charge, your brake may not work. Especially if you live at the top of a hill or even a slight incline like I do.
And don't forget, ATGATT.
EDIT: Some folks below are saying this only happens on "huge hills." This is NOT TRUE. I typically cannot use my brakes at all for the first block and a half even on a perfectly flat road -- the obvious problem here is that a block and a half carries me past an intersection at which I must stop.
My recommendation is to treat an electric skateboard as if it has no brake at all for the first few minutes of riding -- more, if you live on even a slight incline.
