Regen Braking - It's an EV Drivers best friend

Regen Braking – It’s an EV Drivers best friend

Regen. Braking, short for Regenerative Breaking is the art of slowing an EV down without using the brakes. Lift off the accelerator and the car slows down, recharging the battery at the same time.

The Technique

Most modern Electric Vehicles have Regen Braking (Regenerative Breaking) What is it and why is it so helpful?

You know when it’s turned on because immediately, when you take your foot off the accelerator, the car will begin to slow down, without said foot being applied to the Brake. 

Also known as one pedal driving

Finesse this manoevure and one finds oneself having a competition with oneself.

 

Coming up to an intersection, you try and see if one can lift of the accelerator at exactly the right time, so as to stop exactly at said intersection!  There is also no doubt it’s easier to use just one foot to drive, solution to first world problem, sure, but it is very convenient.

 

 

Seriously, though it’s a useful driving technique in an EV and has a couple, if not more, great benefits for the Driver; It recaptures energy while you slow down and with less brake use, they last a lot longer.

EV,Regen Breaking

Captures energy while you slow down

The electricity stored in the EV battery is normally used to drive the electric motor, obvious right!  This is because of the special relationship between magnets and electricity, which powers the car.

 

But let’s not get too technical, suffice to say, the same principal works in reverse.  When the EV is slowing down the reverse happens, kinetic energy turns the motor into a Generator.

 

So for a brief few seconds electricity is actually being generated by motor and is returned for storage in the batteries.  

Doesn’t sound significant, but each small amount during day to day driving adds up and it makes a difference to overall range.

Less brake use equals longer brake life

The other main benefit of Regen. Braking, the traditional brakes aren’t used as much, saving brake pad wear (and replacement cost).

 

When drivers try Regen. Braking for the first time, it can be a strange feeling, it can take a while to get used to.  Lift of the accelerator and you feel an immediate deceleration or braking “effect”, without even touching the brake pedal.

 

What’s happening is that while this is also generating electricity, topping up battery,  magnetic friction is also acting as a brake.

 

Getting used to this is easy.  Coming to a stop you often don’t need to use the brake pedal, saving brake pad wear, so they last longer – bonus!

Regen Braking

All Regen is not equal

When we say most modern Electric Vehicles have the facility, we mean different Brands have placed different levels of importance and control on this Regen.

 

We won’t name names, it’s a big list and spec’s are always changing (often by software update) but generally Regen Braking is available on most EV’s with the level of “feel,” adjustable.

 

Turn it up and with full affect, lift of the accelerator and the vehicle will come to a stop, almost as if you were smoothly breaking (with the brake pedal). 

Dial it down a bit, and it will not decelerate so quickly, and need a bit of a squirt on the break as well.

 

There are some notable Brands who have rejected the Regen concept, suggesting it’s not in the spirit of a Driver’s Car !  We disagree and have come to love it in the Tesla – for us, one pedal driving is the way to go (and stop).

 

Remember, Regenerative Braking is NOT designed to replace braking as a driving technique and we recommend it is used with caution until you get fully used to your own vehicle. 

Brakes can be applied at any time while Regen. Braking, to ensure the care comes to a halt correctly.   It should not be relied upon in emergency situations.
