Confused about charging: is it C K or C L?

As I understand: * K is DC fast charging connectors with the charging range of 50V to 500V. * L is DC fast charging connectors that go up to 920V, sometimes known as ultra fast charging stations. My car's battery is 288V. In the brochure it mentions C L charging, however the charging port has a sticker with C K. Will the car automatically communicate with the charger which voltage it needs?
