Science Scene - Electric Garbage Trucks
The trucks are being built by PVI Electric Powertrain and will feature five strings of seven lithium-ion battery packs providing 250 kWh of energy. The batteries will have a liquid cooling system to keep temperatures in line. Each new truck will reduce CO2 emissions by 130 tons compared to a diesel-fueled truck.
Like city buses, or the hybrid street sweeper that just hit New York City streets, garbage trucks are well-suited for electrification. They have fixed routes, travel at mostly slower speeds and have a lot of stops and starts -- conditions that allow battery power to really excel over diesel or gasoline. The shifts that municipal trucks operate on are also perfect for fitting in recharging or battery swaps.
The electric garbage truck can pick up 16 tons of waste in two rounds of service before needing a recharge or swap. The first truck will be introduced into the Paris suburb of Courbevoie and the next eleven will be in service within the next year.
