Another day, another better battery for consumer product promise. I really hope one day we will get rid of stinking non electric cars from the streets.

Did we ever figure out a valid EV system for heavy trucks that need to drive 600 miles in a 10 hour shift? Seems like a very tall order for standard EV infrastructure and mobile systems

[bryanlarsen]

If you're driving 600 miles in 10 hours without a 30 minute break you should have your license taken away. And 30 minutes is all you need for enough of a charge top-up on a 400 mile battery.

We figured out a system for that in 1881 - electrified railways!

Of course it requires massive capital investment, a modal shift for the last mile, and it's somewhat inflexible.

“Drivers must take a 30-minute break after driving for 8 cumulative hours”

We already have laws.

Janus has some 900 mile configurations.

Thankfully the that doesn’t describe the majority of non-commercial, or even commercial, requirements.

Ideally a lot of the long-haul freight could be handled by rail, but another option for trucks is to have electrified highways. There are some projects in Sweden (one of which uses power rails embedded in slots in the road surface) and Germany (which uses overhead lines).

The slots-in-the-road approach is a bit more expensive, but it can be used by cars and trucks, whereas the overhead lines are just for trucks.

This is just a question of energy density, cost, and how much weight/cost you are willing to add to the truck.

We'll hit that point soon enough (if we haven't already with some nice truck that hasn't crossed my newsfeed). In the meantime, there's lots of shorter haul trucking routes, and routes with access to fast chargers half way (300 mile electric semis definitely exist), to convert.

[wffurr]

I think they are called freight trains.

[chupchap]

I think the current direction is to use hot swappable batteries and I think these have 600km range

[nzeid]

Nobody drives 600 miles in one go.

Range is meaningless, charging speed is everything.
