DC fast charging bypasses the vehicle’s onboard AC-to-DC converter and feeds direct current straight into the battery, enabling much higher power — commonly 50 kW to 350 kW — than AC charging. It is what makes long-distance EV travel practical, taking a typical car from low to high state of charge in tens of minutes rather than hours.
DC charging uses connectors such as CCS2 and CHAdeMO, and its real-world speed depends on the connector, the station’s power rating, and the vehicle’s own charging curve. A "240 kW" station only delivers that to a car and connector able to accept it.
For data, the distinction between AC and DC (and the actual power per connector) is fundamental: it determines trip feasibility, dwell time and cost, so conflating the two, or trusting a single station-level power figure, produces misleading results.
In the Data for EV model
Data for EV records current_type and power_kw per connector, so you can distinguish genuine DC fast-charging capability from AC — and find the real maximum power available at each station across every network.
