This doesn't sound like they are trying to do short routes or fast charging stations. Rather, it sounds like they want to run their EV plows like they run their regular plows.
The majority of LI batteries can be recharged in 1 hour with enough juice. Even if you say "well, it's a truck, so probably needs more time" current level 3 chargers can kick out 350kW of power. Yet this report talks about putting in 50 and 150kw chargers.
The mac trucks they are referencing have 350kWh battery packs in them.
The solution is really quiet simple, recharge the trucks and buy a few more to account for the fact that you have to recharge an hour for every 4 in operation. Stop trying to run your trucks for 12 hours straight.
