Bearing in mind that recharge time increases pro rata with battery capacity.For a given charger power, yes - however it is already possible to charge the large truck battery packs in the same short time window (<45 mins) providing you have enough juice from the charger.
Megawatt (1,000kW - around 4 times the output of a car fast charger) chargers are production ready, and already being rolled out - albeit slowly.
You do need electric grid feed upgrades in many instances however - not exactly trivial.
As with all things in life, there are use cases where an EV truck makes sense. I do a lot of pallet network work at the moment, multi-drop deliveries and collections. Lots of stopping and starting so plenty of free energy from regeneration, and a long run is less than 250 miles. Truck is stationary back at base for at least 45 minutes before the night trunker heads out, so charging window is fine.
My stint on milk tankers was also suitable. 300 miles of trunking/trailer swaps followed by 45 minutes at a dairy whilst tipping. Again, another good charging window.

The rule still holds more battery capacity = more recharge time all else being equal and it will take longer to fill up a battery than a petrol/LPG/hydrogen tank for the equivalent range.
Faster charging means more expense in infrastructure to take the increased load and more energy losses in heat and higher price per kWh.
More demand for electric also means more nuclear energy requirement thereby worsening the odds of a nuclear disaster.
To be fair that would also include hydrogen production.
All to solve a non existent problem although ditching diesel in favour of LPG would certainly solve the diesel emissions issue.
