Quick question about Electric or Diesel Vans Economy
Posted by Ken Wood on March 28, 2023, 10:29:28
I had a delivery the other day, from eBay not Amazon, a diesel van not electric. After a quick chat with the driver, I asked why not an electric van, he laughed saying Amazon drivers with electric vans have to do two runs because of the weight restriction on the payload as opposed to diesel vans, I found this very interesting as my background was in logistics, so here is the question, is it more economical or even greener to use electric vehicles. Amazon use Mercedes vans with an all-electric, payload capacity of 731kg as opposed to Diesel van is 1413kg nearly twice the payload, lot better than the electric as it can load up more parcels and less traveling to return to the depot and reload even more time then return to complete company deliveries. When one starts to work out the logistics, it gets even darker shades of green, let’s take a number say 50 vans all diesel versus 50 electric vans, the diesel vans can carry 100 parcels and complete 150 miles per day and take 6 hours and two hours loading and rest times total 8 hours. Electric vans can only carry 50 parcels and complete first run 75 miles in 3 hours, but that electric van now has to return to the depot to reload now that could be 20 miles return then one hour to reload, then 20 mils to return to the place where he/she left off on first run, this has now added 40 miles and loading times and travel times added another 2 hours, the n another 3 hours to complete the other 50 parcels delivery, it get no better because the diesel vans only had a traffic impact by adding 50 vehicles to the daily traffic jams and fuel emissions were within EU standards, together with road wear together as the van unloaded lighter the van got lighter the full economy get better and just doing one run was also better for the environment as less traffic congestion, now let’s look at the electric van two runs now heading back into traffic for the second time with another 50 parcels and now another 3.5 hours to work because of the 20 miles to return to the place where he/she left off, completing all deliveries not 150 miles but 190 miles = 150 x 20 x 2 = 40 total 190 miles hours worked 10 hours because of the return to the depot and reloading then return to place to re-join deliveries and maybe more as the traffic later in that day traffic may or may not have increased. In summary, whilst electricity looks greener the truth is not so green, lots of situations are cropping up that are never reported, the RAC & AA rescue have diesel generators to recharge vehicles that run out of charge, bus companies are charging electric buses up with very large diesel engines generators, so many situations never reported because of the superpowers demanding on secrecy. Hope you enjoyed my little rant, I am sure some will have an input, but my bets are on hydrogen power will win the day eventually.
