Yes, the inrush current limiting circuit you described would work. The circuit would use a thermistor to limit the inrush current to the DC fast charger. The thermistor would have a high resistance when it is cold, which would limit the current flow. As the thermistor warms up, its resistance would decrease, allowing more current to flow.
