2 mins to charge a 40 kWh battery is 1.2 MW. I can't see that happening any time soon.
You are almost certainly not charging from 0->100%. It's probably more like 10%->90% which gives you 32kW to charge. We currently have 350kW chargers on the market, they'd do that in ~6 minutes.
At some point trying to get 2 minutes vs 6 minutes is just silly nit picking.
