Two North Carolina cities made national news recently as they started using trash trucks run by electricity, not petroleum. The Wall Street Journal ran a story October 7, Electric Trash Trucks Are Coming Quietly to Your Town.
Quietly is a key. Gone are the churn and chug of old trucks. Also gone are the belching emissions from the diesel engines.
Greensboro and Hickory, North Carolina, are the cities featured. “Greensboro-based Mack trucks has put another pre-production Mack LR Electric refuse vehicle into service for a real-world trial. The company delivered a vehicle to Republic Services in Hickory, where it will test it in one of its residential recycling collection routes. The truck will be evaluated for its range, functionality and payload capacity.” (Source, images and quote)
The fun of the WSJ report is that their chief auto reviewer tested the trash trucks. Liked them, too. “Also missing from my test drive was the shrill, regular chuffing of air brakes. EV trash trucks will incorporate regenerative braking, using the hunkka e-motors to halt the truck without resorting to the mechanical brakes. The instant I lifted my foot off the accelerator, the big truck slowed like it had hit a sand dune.”
For motor heads reading here, these are heavy-duty trucks: “The Republic Mack LR Electric is equipped with two electric motors with a combined output of 536 peak horsepower. The powertrain delivers 4,051 lb.-ft. of torque available from zero RPM, which is fed through a two-speed Mack Powershift transmission to Mack’s proprietary S462R 46,000-pound rear axles. Four NMC lithium-ion (Lithium Nickel Manganese Cobalt Oxide) batteries are charged via a 150kW, SAE J1772-compliant charging system. All accessories are electrically driven through 12V, 24V and 600V circuits.” (Source)
