ADAPTIVE DC CHARGING CABLE LOSS COMPENSATION FOR EV CHARGING

摘要

The invention relates to an electrical vehicle charging system for charging an electrical vehicle (1) with DC energy, comprising a charger (2) configured for delivering the DC energy, a DC charging cable (3) having a first end (9) and a second end (10), whereby the first end (9) is connected to the charger (2) for receiving a DC voltage and the second end (10) is configured for connecting the electrical vehicle (1), a DC voltage sensor (4) configured, if a DC current greater zero flows from the charger (2) to the electrical vehicle (1), for measuring at least a first DC voltage at the first end (9) and for determining a differential DC voltage between the first DC voltage and a second DC voltage measured at the second end (10), and a DC voltage adjustment device (5) configured for raising the DC voltage to compensate the differential DC voltage.
