Unfortunately the range is becoming a problem on big electric trucks. The batteries cannot store as much energy per weight unit as the chemical fuel. This can be circumvented by using electric wiring overhead.
Sweden is prototyping an electric highway for trucks. It'll make transport cheaper and less damaging to the environment.
- hx87 10y agoIt's less of a problem in dense urban areas, where distances are short and there are many opportunities for regenerative braking.
- bluedino 10y ago>> Unfortunately the range is becoming a problem on big electric trucks. Right, there's only a 126 mile maximum range on that truck. So you'd have to stop and get a new battery every 2 hours, minimum on the interstate.
- fu9ar 10y agoThe point of an urban transport truck is to transport goods within dense urban areas so that we don't have to suck down exhaust fumes all damn day. Your objection is absolutely irrelevant. You could have realized that by reading the entire title of the article!
- mikeash 10y agoAn "urban transport truck" would do poorly on the interstate? How unexpected!
- bluedino 10y agoI'm just adding to the post I replied to, I realize it is an urban truck

This specific effort is urban deliveries, 120 miles should be way more than enough. > This can be circumvented by using electric wiring overhead. You'd need much denser pantograph networks than any I know of for debatable benefits since the vehicles would still need the ability to go "off-network" (to enter private premises for instance). And for longer ranges, you might as well just use trains.
- PeterisP 10y agoIt's not as simple - with current charging speeds, 120 mile charge is not enough even if you're doing 10 mile deliveries; you need to figure out some solution that can keep that truck running for e.g. a 12 hour shift with limited downtime. A gas tank with barely enough gas for 120 miles would work, but a battery for 120 miles can work only if you can quickly, easily and safely swap the batteries in your depot.
- umeshunni 10y agoA fast (level 3) charger can recharge a 120 mile truck battery in 1-2hrs today and potentially less than an hour in the future. A Tesla Model X (5000lbs/2500kg) pulling a 5000lbs trailer uses about 700Wh/mi. If you assume 1kWh/mi for a small delivery truck, you'll need a 120KWh battery. ChaDeMo chargers are ~62.5KW, Tesla Superchargers are ~135KW and future level 3 chargers could go up to 300KW.
- thinkcontext 10y ago> 1-2hrs So 12.5-25% of an 8hr shift. I would guess that would be unacceptably long for a large number of transport operators.
