regenerative braking

Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This method contrasts with conventional braking systems. In those systems, the excess kinetic energy is converted to unwanted and wasted heat due to friction in the brakes, or with rheostatic brakes, where the energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can significantly extend the life of the braking system as the mechanical parts will not wear out quickly.

    Can newer models save the One Pedal Drive setting?

    I think I I have came across this somewhere a while back and just want to verify if that is actually true? My 09/2023 Lux on R67 does not save it - how about the newer models like 2024/25?

    Going backwards

    I am currently driving an MG4 while my S5 is in the dealers. The MG4 seems to remember the regeneration used on the last drive, so I don't have to set it to my liking each time I drive. Also the under the radio display on the main screen the currently playing track info scrolls, it S5 does not...

    Energy Regeneration

    The regenerative braking on an EV can be set to various levels:- Hardly any regeneration, the car will coast when the accelerator pedal is released (hardly any regeneration). Strong regeneration, when the accelerator pedal is released there is a strong braking effect and the brake lights come...

    MG4 Xpower power brakes and regenerative braking suddenly not working

    Today I was toggling between the various driving modes, in the mean time on screen checking which wheels were powered. I ended in Sport mode again. When I had to slow down for the next crossing the car was regenerative braking, but not enough to halt in time. It also felt like the regenerative...

    Anyone done any consumption figures on the IM5

    Had my IM5 standard model now for six weeks and through the weather conditions encountered so far averaged between 2.7-3.1 miles per kWh on mixed driving conditions and journeys, mainly town and rural, no motorways. Playing around with regen between options I get the best consumption with...

    Regen Braking & Rear Brake Lights

    Just a general question. I use regen 3 a lot, and therefore very rarely use the brake pedal. Now I don't have eyes in the back of my head, so never know if my brake lights come on (if ever). Does anyone know if they come on automatically ? Just asking, not very important to know. Many thanks

    MGS5 didn’t accelerate in uphill slope

    Hi everyone. 2 days back while I was driving my MGS5 uphill in a real slope when I had to stop and hold for another car coming downwards. Then when I started to climb again, the car didn’t respond at all . Then I changed mode to SPORT and again pressed the accelerator full but the car moved very...

    Vehicle Control System Fault

    Well it’s back! After first encountering this vehicle control system fault on my 2023 XPower back in June 24 when the dealer did some updates and unplugged and reconnected some modules it’s now back and more annoying than ever. Power limited to 9% with accelerator pressed to the floor, take...

    Pilot question

    Hi all, This is something I noticed during the weekend while I was driving around and playing with the pilot mode. When I am driving the moment I start hitting the brakes and all the way down to 3 mph the car regens. I can see it clearly in the energy consumption graph on the driver's display...

    Regenerative Braking: beginners explanation, please

    Please explain it to me like I’ve never owned an EV before! :) I understand the one-pedal driving concept. Seems like a good idea but not one for me, at least not yet anyway. I also get the mechanics behind regenerative braking, it’s more the selecting of 1/2/3/A that I’m asking about. Is this...

    Regenerative braking inconsistency and danger

    I find that having regenerative braking enabled is very dangerous in this car. Its efficiency slowing the car depends on how much battery is full. If it is full, it will not slow down the car and i find my self in panic when it does that. If I let go gas peddal I would expect that it will always...

    Setting the left shortcut button

    I'd like to set a shortcut button to change the Regen setting (because it sticks to 3!). I've seen people report that they can program the left shortcut button to do this - but I don't get that option. Is there another way?

    Level 1 regeneration. MGS5.

    Well, having written reams on how level 1 regen is the one for me, I've been trying level 2 regen and I'm actually finding its pretty good. Bit of a shame the setting cannot it seems be stored as my preferred setting, but its not the end of the world considering what a good car it is.

    One pedal driving vs KERs

    Is it possible to get the car to start with KERS set to 3 and not 1? It seems to remember everything else.

    we need a level 3 regenerative braking

    2 isnt enough. You still need to use the brake pedal too much - and when you use the brake you can see the power going more negative when means pressing the brake increases the regenerative braking more before the actual brakes are eventually applied. I actually find this baffling and infuriating.

    Transmission Whine

    We've had our GT model for nearly 3 months and covered about 1200 miles. I've become irritated by what I'd describe as a 'transmission whine' towards the rear which is obvious when gently coming off the accelerator between 25 to 30 MPH. I'm not sure if it's getting worse, but I'm certainly...

    Does the Cyberster use regenerative braking when in Adaptive Cruise Control?

    I read in another MG thread that other MG EVs do not use regenerative braking when in Adaptive Cruise Control, does this apply to the Cyberster?

    Wanted to change default 2 setting for the regenerative breaking to setting 1 and it does work well for a single journey.

    Foot brake ..regen?

    Based on my experiments it seems that braking does not use regen in itself...is that other peoples view? Different kers setting impacts the regen but for example if on kers 1 and then use the brake it seems to be capped at a lower level, kers 2 a slightly higher level etc.. My previous leaf...
