Question: How did power, voltage, and current capabilities change from CCS 1.0 to CCS 2.0?
Answer: For DC charging CCS 1.0 supports only charging powers up to 80 kW, voltages up to 500 V, and currents up to 200 A, whereas CCS 2.0 supports charging powers up to 350 kW, voltages from 200 to 1000 V, and currents up to 500 A
