BMW i3 Regenerative Brake Light Test – Video

JUL 4 2014 BY ELECTRICCARSTV 4

Obviously, it’s not easy to check for yourself when the brake lights do and do not illuminate under regenerative braking, but whether or not the lights illuminate is a valid safety concern for most owners of plug-in electric vehicles.

To see when the BMW i3 lights illuminate under regenerative braking, BMW i3 owner David Vottero tested it out by strapping 4 GoPros to his i3 and then driving it around town.

The split-screen video is the end result.

Very cool…when I first got my MiniE years ago we all wondered the same thing…..will I look like a dope braking up hill ๐Ÿ˜‰

All Great! But wouldn’t it be better to integrate energy regenerative mechanism into breaking itself? Meaning, once breaks are applied, engages energy regeneration.
Just a thought ))

No, I highly prefer doing one pedal driving as much as possible. I don’t quite understand those people that think there should only be regen when actually braking. If I am headed downhill and have more speed than what I have given on the accelerator – go ahead and regen. If I don’t want regen – I will simply apply a little more pressure to the accelerator.

I feel that when I actually do press the brake pedal that the vehicle may actually be applying the physical brakes too in addition to whatever regen it can get – which may not necessarily be the case – but why waste any energy that could have been recaptured?

No, it’s really quite simple.

Drive your vehicle at night and watch for the reflection of your brake lights on the signs. That’s how I determined the i-MiEV does NOT turn on its brake lights even under high levels of regenerative braking.
