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.

    Liking Snow mode ;o)

    Tried snow mode today as there was a light covering on our road and I'm loving it. It's so smooth on take off and unlike eco mode, the brakes don't feel soggy. The regen being less severe worked great on a steep hill I go down where, in normal mode, I usually have to press the accelerator a bit...

    MG4 EV 51kWh Traffic Efficiency

    Hi all, I have been using my 51 kWh MG4 EV Magnify iSmart (I guess the Trophy Standard Range in many countries) for 2 weeks and 1200km in Indonesia and have been loving it so far. I just have several issues, starting with the range. I believe in the UK the rated WLTP is at 218 miles, which is...

    when the car is regenerative braking, do the stop lights come on?

    Regenerative Braking

    I’ve been wondering how regenerative braking extends the available range compared with simply coasting whenever possible. My last car, a Merc 250e (hybrid) had coasting as one of the regen options selectable by paddles behind the steering wheel, and when you had to use the brakes while coasting...

    At what SOC is one pedal driving available?

    I recently got the base model MG4 (called Excite 51 in Australia, SE SR in UK) and though initially not expecting it to have one pedal driving (OPD) found that the latest update before delivery indeed made it a feature of even this model. I got used to the subtly different driving style it needs...

    What does an MG4 remember?

    Hello all, loving all your work and have been a voyeur of the forum for some time whilst making my buying decision. Picked up a Grey Trophy last week and so far so good apart from the normal stuff (I detest LKA...) Wondering if there is actually a list of what settings the car does remember...

    regen not working ?

    Not sure if the regen is working , mechanically it seems to work ie when you take your foot off the accelerator the regen kicks in however when i look at the display on the central screen it shows no benefit being achieved from regen , Also the little graph thing doesnt seem to work .. Any ideas

    First long run miles/KW

    So picked the Trophy up yesterday and had a run today from Manchester to south Shropshire on a mix of motorway and A roads and got 4.4 mikes/Kw which thanks to the warm weather I don’t think is too bad - had to run the A/C as it’s so hot😀 Pleased to see I got 7 KW regen too Sorry for the...

    Braking queries

    In addition to the MG4 which my wife drives, I also own a Skoda Enyaq. In the Enyaq, the "HOLD" parking brake works and is displayed on the control panel when it is applied and this applies whether the vehicle is in forward or reverse mode. However, in the MG4 there appears to be no visual...

    Adaptive Cruise Control and regenerative braking question

    I just did my first long motorway trip in the ZSEV. I love the ACC but I notice if the car slows from say 70mph to 60mph because of traffic ahead when it stops accelerating and starts breaking you don’t get any regenerative breaking so nothing on the automatic slow down is going back into the...

    Cruise control and regenerative braking

    I have a ZS which was new last August but I have only started using cruise control recently. I have noticed that when the cruise control slows the car, because I am approaching a slower moving vehicle, there doesn’t appear to be any regeneration happening - no green light on the power side of...

    Regenerative braking effect reduced warning on dash?

    This started yesterday on startup. The warning “Regenerative Braking Effect Reduced” flashes up on the drivers binicle on start up. Is this a ‘return to dealer’ issue, or can it be fixed easily? 🤔

    Regenerative Braking - Range Increase

    Hello All, I always wondered how and when does the regenerative braking put back mileage/range back into the battery? I'm assuming it will do this when the car is turned off and the battery starts to settle? I say this because last night after a long trip, the range to empty was at 40 miles...

    MG ZS EV regenerative braking is limited please use brake

    Has anybody else had this issue? Using the new comfort software update if that is of help, cant find any record of this error within the user manual or any google search! any help appreciated!

    Use of KERS (regenerative braking) on the MG ZS EV

    I have been the different articles regarding range etc. and notice that KERS is hardly mentioned. Why is this, I would be interested to know how this has been used, and if so does this affect obtainable range
