Sure, there are all sorts of workarounds you can apply, but all those workarounds have costs. At the end of the day, economics rules, and if doing all those workarounds costs more than just putting in a bigger battery, they’ll just put in a bigger battery.
Also, you’re forgetting something important: most countries have laws limiting driver hours / mandating driver rest. As a practical matter, with appropriately spaced charging stations, a tractor like the one Tesla built effectively imposes no cost in terms of charging time. That’s because the mandatory driver rest periods are sufficient to charge the battery using today’s battery & charging technology. And on that topic, if you try swapping a battery with a forklift, you’ve already lost (in terms of time). You need a dedicated battery swap machine for the “time economics” of battery swap to make any sense.
So why bother with all kinds of expensive connectors, and the rest when you don’t need it anyway? That’s what you’re up against.
- klyrs 3y agoWhile I don't have a rosy view of swappable batteries in general, I must pick a nit. Drivers are mandated rests, but the trucks are not. A delivery company could operate swappable EVs at near 100% uptime.
- labcomputer 3y agoFair point, and you could have multiple drivers too. But the most common objection to BEV trucks is with regard to long haul semis.
