    capable of recharging from 0% to 100% in 20 to 25 minutes

    That’s the most insane part of this. Wouldn’t you want this to have the battery capacity for 4-12 hours and let it recharge over night?

      There’s two modes of thought when it comes to charging

      1. like you mentioned: a slow AC charge overnight. Benefit here is you can slow down the charge at times of the night when electricity happens to be expensive.

      2. a fast DC charge that takes no longer than a lunch break. We typically size these batteries such that they can run till lunch, take a fast DC charge over the lunch break, and then are ready by the time lunch is over to complete the rest of the shift.

      Mining is a 24/7 operation. There is no “over night” rest period. You need batteries that can charge during breaks for workers and usually they have 3 breaks in a 12 hour shift.

      So 4 hours runtime, 20 minutes back to full charge is a pretty good fit.

      Never mind the couple of megawatts needed to charge a 600kW battery in 1/3rd of an hour. 2 MW is enough to comfortably power ~100 homes. Have a fleet of these on charge and you’re drawing the same amount of power as a small town.
