It's even more fundamental than that. The power rating of DC fast chargers is based on their maximum voltage of 500V, but the actual limit is the current (measured in amps) and not the voltage. So an 80kW charger has a maximum current of 160amps (500V x 160A = 80,000W or 80kW).
BUT - the Bolt maxes out at the mid-300 volts at the low states of charge where the maximum charge rates are possible. At those lower voltage levels the charger is still limited to 160A, and so it will only be able to deliver around 56kW (350V x 160A = 56kW). And THEN you have to subtract any power used for HVAC or battery conditioning.
