Reply to comment by Vinyalonde in Caterpillar Successfully Tests First All-Electric Large Mining Truck by Sorin61

A lot of these haul trucks run electric motors already. The wheels have electric motors and the diesel engine just spins an alternator. This just replaces the Diesel engine with batteries.

Yes , you are right. I used to work on them. The wheel motors were huge. If my memory serves, I think they were direct current.
