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 with DC energy, including a charger configured for delivering the DC energy, a DC charging cable having a first end and a second end, the first end is connected to the charger for receiving a DC voltage and the second end is configured for connecting the electrical vehicle, a DC voltage sensor configured, if a DC current greater zero flows from the charger to the electrical vehicle, for measuring at least a first DC voltage at the first end and for determining a differential DC voltage between the first DC voltage and a second DC voltage measured at the second end, and a DC voltage adjustment device configured for raising the DC voltage to compensate the differential DC voltage.
