depends how you look at it, but for regenerative breaking, it can be trivial to generate spikes of 10-40kw.
Having a battery that can handle that and not get hot or loose capacity is really useful.
As for 500kw chargers, depending on the round trip efficiency and the discharge rate, using these batteries as a charging source would seem reasonable. It also would be useful for grid stabilization, having something that can instantly absorb a few megawatts would be really useful.
