Re: Tesla semi?
The issue with regenerative breaking we have found is that you need really, really big super capacitors, which are physical big and expensive. Batteries can't take charge as fast as breaking produces it and a fully laden truck will produce a great deal of current indeed under breaking. You can then charge the batteries off the super capacitors so as to leave them empty for recharging next time you break, if you're doing this for range (as we were) rather than speed (as F1 does). People generally use big resistors (which need cooling) to dump any current that doesn't fit in the capacitor.
