Regenerative braking down grades should be a huge advantage for electric motors over a diesel engine. So even if you expend the same amount of energy going up, you recapture the braking energy going down. You can't recapture that energy when using jakes or service brakes to slow down.
I'm curious how powerful the regenerative braking is when fully loaded. I know they're extremely effective in slowing down passenger vehicles. But will it be enough to hold a set speed without using the brake pedal? It kind of sucks that there's a huge focus on how fast it can pull a load up hill, when they should be highlighting performance specs for down hill.

The motors themselves would be able to handle it, as their power limits are the same whether they're acting as motors or generators/alternators, but most likely much of the recapture would have to be dumped as heat thru a resistive grid as excess input current degrades battery life.petefan4000, Another Canadian driver and Accidental Trucker Thank this. -

I have not doubt that electric wouldn’t work just as well if not batter than a ICE, but electricity storage is the big issue.Another Canadian driver and Hammer166 Thank this. -

We'd be far better off focusing on fuel cells rather than batteries. Even a switch to diesel-electric drive train with centrifugal or capacitor storage of recouped braking energy is a better option than batteries.
Wind and solar aren't up to the task of powering our transport sector. The grid is already stressed, and new power plants aren't exactly popping up everywhere. Transportation needs onboard prime movers and fuel, whatever tech that ends up being. There's a place for batteries in some sectors, but to think it's a cure all is foolish. Of course, the idiots pushing all this live where they think 30 miles is a long drive. They can't even grasp the pushback from folks unlike them.Another Canadian driver Thanks this. -

Electric trucks will have limited applications.
Local, regional, last mile.
My take. I'm not a prophet, though.petefan4000, Blu_Ogre and Hammer166 Thank this. -

Then I remember the over engineered crap that the German automotive industry spits year after year.
Simple and clean design is always overlooked. Always.
I say it as a production team member up to QC final stage in Consumer Electronics. 10 years.
Industrial Electronics 10 years and IT 9 years. Before driving a truck, for 21 years, I mean.
I saw crap engineering for 50 years . It's everywhere, like a curse.God prefers Diesels, dwells40, Hammer166 and 1 other person Thank this.
