Charger Hogs
"Fast " chargers aren't designed for a fast full charge because that would harm the battery, so they slow down after 80%

it’s not a Starbucks line; it’s a slow “fast” charger lineup
I learn something new every day. “Fast” chargers slow down after reaching an 80% charge. If someone wants to wait for a full charge, the time on the charger will approximately double, often causing long lines to form impatiently behind them.
excerpts:
“Fast charging can be stressful for a car’s batteries, though. So, to protect batteries from damage, charging speeds slow way down once batteries get beyond 80% full. In fact, it can take as long, or even longer, to go from 80% charged to completely full than to reach 80%. Meanwhile, lines of electric vehicles wait behind almost-full cars…
Electrify America, one of America’s biggest charging companies, is experimenting with a solution to the problem of charger hogs who can make it slow and unpleasant to travel in an EV. At 10 of the busiest EV fast charging stations in California, Electrify America has enacted a strict limit. Once a car’s batteries are 85% charged, charging will automatically stop and the driver will be told to unplug and leave or face additional 40-cent-per-minute “idle time” fees for taking the space.
It’s similar to something Tesla vehicles do automatically. When a Tesla car, truck or SUV plugs into a particularly heavily-used Supercharger station, the vehicle itself may automatically limit charging to just 80% “to reduce congestion,” according to Tesla’s on-line Supercharger Support web page.
In that case, though, the user can still override the limit using the vehicle’s touchscreen. There will be no getting around Electrify America’s limit.”
I think the US Army can use this model to recharge its battle tanks after President Biden/Harris's mandate updates the readiness factor for our combat forces. Enemy tanks will be compelled to wait until American tanks are charged to 80% before engaging in combat, and American tanks will queue up according to the seniority of the tank commander. The Progressive Tank Treaty will guarantee that no one takes advantage of any tank that is either charging or on queue to charge, and prohibits attacking a tank with low charge, provided it hoists a red "Uncharged" flag or a white "Dead" flag, giving crews a chance to tow it back to the nearest charging station.
