Volt Has Regenerative Braking

 
 

Posted by Lyle in: Engineering with 6 Comments

 

We had previously been discussing whether the Volt has a regenerative braking system. It would seem logical that it should, as the current breed of hybrids do. Well it is official, we have heard back from GM and the official word is yes, there is a regenerative braking system.

The system seems the same as the production systems found now:

” When the brake pedal is applied (foot comes off accelerator pedal)
the Electric Traction motor switches to a “Generator”.

The “Generator” mode of the traction motor creates a reverse torque
force to the front wheels…..slowing the car down. The reverse torque
force is caused by the traction motor “Generator” making electricity
which is directed into the battery. ”

….General Motors

    Rich Lannen from GM tells us more about regenerative braking on the Volt in this podcast…

    Correct. Regen is obviously a part of the e-drive system. The previous thread that questioned an EV range disparity between the Scion EV and the Volt insinuated the lack of regen. The range disparity is due to PHEV battery utilization that will likely only use 50% of the battery, from 90% to 30% SOC, to maintain high performance, good HEV action under “depleted” operation and a 10 year/100k mile life time.

    This is a very important feature. So much energy is wasted and lost through braking. I didn’t see regen braking in the specifications so I searched for this info. The EV1 had it, glad to see its being used and it will most likely be a standard feature on all EV’s.

    I’m just getting started with blogging and have learned some nice techniques from your site. Thanks!
