ToyotaMan, you hit the nail on the head. The regen does little to recharge the battery. I think the next step in reducing energy consumption is to capture the energy in capacitors. It is just a matter of time before the manufacturers figure out a system to re use the energy from regen braking or for that matter regen when the truck is lowering. Jungheinrich has regen when their stockpickers lower. Not sure if that is going back to the battery or they have capacitors or some batteries besides the lead acid battery in the truck to re use the energy captured from regen.
