Tevva And ZF Develop A 4x More Efficient Regen Braking System
The title of this post, is the same as that of this article on Electric & Hybrid Vehicle Technology International.
This is the first paragraph.
British electric vehicle manufacturer Tevva has successfully completed development of the regenerative braking system on its 7.5t battery-electric truck. Part of this involved working with global Tier 1 supplier ZF to integrate its electronic brake system (EBS) for use in zero-emission Tevva electric trucks.
I like what I read about Tevva and I suspect, if I still had horses, one of their trucks would make an ideal chassis for a non-HGV horse box.
The Anonymous Widower 
The TVP article talks about Tevva and ZF creating ….”a (EBS) system that recuperates up to four times more energy than a conventional compressed air brake system.” Since a conventional air brake system doesn’t recuperate any energy, it merely converts it to heat through mechanical wear (friction), the energy recovered through regeneration is infinity greater.
I think what was meant was a comparison between an electro-pneumatically controlled and conventionally controlled pneumatic system.
Well conventionally controlled pneumatic system are old hat, all of the major suppliers of brake control systems, Knorr, Wabco, Haldex and ZF have been promoting EBS for around twenty years, you can still procure legacy systems but as much as I like Tevva’s product there’s no real pioneering here.
