The largest barrier right now to mass-market EV adoption is, in fact, the charging problem. Not enough speed charging stations world wide. The problem, though, is that a 250kW inverter costs, at least in this case, $57,600 and is about the size of a very large fridge. Therefore, what the industry needs is not faster chargers, but more chargers, which is hugely difficult given the enormous cost of fast chargers.
