Caterpillar has demonstrated the 793 Electric prototype at their Tucson Proving Grounds in Green Valley, Arizona. If you’re not familiar, this allows potential Caterpillar customers to test the trucks on a seven-kilometer course in scenarios similar to real-life operations. During the demonstration, the 793 Electric’s bed was loaded with material from a quarry that needed to be transported to a nearby storage area, just like any other heavy truck in normal operations. Fully loaded, the truck achieved a top speed of 60 kilometerper hour. It also had to travel one kilometer up a 10% grade at 12 kilometer perhour and then down, capturing the energy that would normally be lost to heat and regenerating that energy to the battery. Upon completing the entire run, the truck maintained enough battery charge to allow additional cycles, although it was unclear how many until it needed recharging.
