Love the attention to detail with the BMW not indicating for the corner. Keep up the good work.

Regenerative breaking is also used by trains and trolleybuses and the energy is transferred back to the network

The rear motor in Tesla, Volkswagen and Hyundai electric cars is not the induction motor you have represented in the video. They all use a Permanent Magnet Synchronous Motor (PMSM) but the video is still valid because the principle of regeneration is the same. The only difference is that rotor and the stator magnetic field rotate at the same speed: the machine is synchronous. Thanks for the good video.

2:55 I am not sure about Tesla EVs in particular but in general, the power produced from regenerative braking by the inverter is in DC format only. Inverters normally change DC to AC so when operated on reverse, they change the AC power from the motor into DC. So there is no need for an additional rectifier.

But this DC power needs to be brought to a the right voltage for charging the battery, which is where the DC to DC converter comes in. Another interesting thing is that usually this part requires very little additional hardware, as the on-board charger used in most EVs also consists of a DC to DC converter - and that same one is used for charging the battery during regenerative braking, as the on board charger is not in use during driving.

I’m just happy to see that your channel knows the difference between “Braking” and “Breaking” since many here clearly don’t…😅

Tesla now allows regen braking all the way to a full stop. It use to be to about 5mph before the friction brake was needed…. Now I haven’t touched my brake pedal in a long long time

[stevenhill]

Applying friction brakes for complete stop no longer required when optional setting is enabled

[jacekmierzejewski]

Lorentz force vector should point in the opposite direction. This mistake probably occurred because the direction of the induced currents in the rotor is also wrong.

[Cybernatural]

It is probably quite similar, but I would love to see an update with the permanent magnet motors, and how they use one pedal driving right down to Fu stop.

Lesiscs is struggling. And we must have to support them because of chapri youtuber can get million view, why we can't support education.

We're Indian where education is born first. Let's appreciate this man's (Mr.Mathew) effort

After a long time lesics is back hope you will be the most viewed channel❤

It would be interesting to see how Tesla has been achieving a very precise control of the vehicle movement at low speeds now, it seems like it actually uses energy when coming to a stop at low speed downhill and I would also presume on a flat surface too, it's just negligent compared to the energy needed to stop at downhill scenarios

Regenerative braking can fully stop the car these days without using the friction brakes

[chrism]

Gotta love in some car models it does not put the brake lights on when regenerative braking is applied. Is a loophole in the law. If a car in front of you is at max regenerative braking it will be slowing down pretty significantly and there will be no brake lights to tell you. Brakes lights only have to be on when friction braking is applied. Till the loophole in the law is fixed you rear end one, , brake light on or not, your fault.

[Flash]

Always wondered how the brake lights would work with that, and the effect on rear end collisions

[gabedarrett]

4:00 I heard somewhere that it's between 20-60%, not 10%.

Is there a way to actively control regenerative braking torque? The problem with modern regenerative braking is that you have to try and estimate when to remove your foot from the accelerator pedal in order to minimize wasted energy. If you estimate the timing incorrectly, you'll need to use friction brakes at the end, which wastes energy.

Excellent video! Had to watch a couple of times 1:53 to 3:10 was the answer I was looking for.

[fin]

I drive all the time never hitting the brakes. in combination of my timing and Tesla got real good at giving the right amounts of regen. I knows if there is a stop sige or red light coming up

[commieTerminator]

Tell me why we can't force motor to rotate in reverse direction in order to completely stop the car without friction braking

This video is very informative, thank you so much Tesla. Keep up the good work ❤
