Actually, garbage trucks are one of the very few applications where EVs COULD be useful. Garbage trucks make very frequent starts and stops. IF the energy used to accelerate the truck could be recovered while the truck is stopping, they would have significantly extended range. The problem with this is that present batteries cannot be recharged at the rate required to make this possible. The batteries simply cannot efficiently accept this rate of charging. The electric motors are fully capable of charging and discharging at the required rate, batteries aren’t. This is why battery charging times are so long (along with insufficient electrical power delivered to the charging stations).
Recently, I stopped at a local supermarket, and was surprised to see a mountain of trash in the parking lot. It turns out a trash truck had broken down, so they had to unload it so it could be towed to a shop. Meanwhile, another truck showed up to haul the trash away to a distant landfill.
Expect to see more of this if they switch to electric trash trucks.
Hybrid garbage trucks would make a lot of sense. Toyota could scale up the Prius drivetrain.
